Autoimmunity

Spring is here!.jpg

My previous motivation to write blogs was to inform everyone of all the things I knew, how I could help them and why I was probably correct with a healthy smattering of dogma. These days my motivation has changed and I suppose it goes with the old adage - The more you know, the less certain you become of a subject. Sometimes my purpose to write is to take what I have learnt or discovered and set it down for others to contest it, or to go back years later to compare current to previous writings and if my thoughts have stood the test of time.

 With auto immune disease (AI) protocols, I intend to discuss some of the problems associated with assuming that

a)    that the immune system has lost sense of self and is attacking itself at will.

b)    most of the foods suggested are optimal from an AI perspective

 For an example let’s take one of the most common AI diseases related to thyroid function such as Hashimoto’s which is the most common cause of hypothyroidism.

‘Hashimoto/lymphocytic thyroiditis is an immunologic disorder in which lymphocytes become sensitised to thyroidal antigens and auto-antigen bodies are formed react with those antigens (Gardner et al., 2011).’

 Many recommend and invoke a drastic change to diet. The suggestion of an auto immune paleo type diet, which actually has some merit segmentally but perhaps loses sight of the main issues that drive an auto immune reaction. I’ll address the positives and negatives in the next blog but a common theme that dairy is problematic, and should be removed might better serve an individual if they were aware that it’s their stressed system that drives the response. Much like the assumptions that fruit should be restricted due to sugar content, which matches the dogma that sugar causes diabetes and removes key nutrients that enable efficient metabolism.

 So, on to what might be the most pertinent point of this post. A definition of an auto immune disease (AI) is the following:

 Auto-immune disease may result from the interaction of the genetic load of the individual, modification of self-tissue antigens by environmental agents such as virus or drugs and abnormalities of the immunological system itself such as the loss of controlling or suppressor T cells with age. In the majority of people the outcome is tolerance, maintenance of normal tissue architecture and function. In the unfortunate few the outcome is auto-immune disease, that is, failure to recognize ‘self’. (Panayi, 1976)

 This seems quite logical doesn’t it? The body must be attacking itself because it’s producing antibodies against its own tissues, a clear case of autoimmunity. Diagnosis of Hashimoto’s is usually based upon levels of the anti thyroid peroxidase (ATPO) and thyroglobulin antibodies (TgAb). The higher the levels the increased likelihood of autoimmunity. Increased and sustained antibodies must mean increased autoimmunity and the nefarious nature of attacking oneself.

However there are some that theorise a different view. Enter the Danger Theory proposed by Dr Polly Matzinger who suggests that the immune system is particularly good at recognising damaged and potentially dangerous tissue.

Invoking Occam’s razor and the simplest explanation seems the best choice, although the issues are just as complex. Using the example of the thyroid again as it’s the most common cancer diagnosed and susceptible to a number of insults namely pollution, stress, poor nutrition, preservatives like nitrates/nitrites and a significant factor is estrogen. Matzinger’s suggestions that heat shock proteins (HSP’s) could be at the heart of the AI response to a viral infection and increased temperatures. Estrogen’s actions would be slightly different but their action ultimately decreases body temperature by inhibition of thyroid function, inactivating enzymes, leading to unfolding of proteins.

Estrogen and disorganised tissue has long been implicated in cancer.  L.C. Strong who bred mice for genetic evaluation found back in the 1930’s the implications of estrogen and mutations.

Leonell C. Strong

‘“ The second contribution of genetics was the production and control of biological states that differed in cancer susceptibility and cancer resistance. This contribution made possible the discovery that the female hormone estrogen, was involved in the origin of several kinds of cancer in mice.”


AI disease is 80% more likely in females and estrogen can be considered a primary driver. Increasingly the role of environmental pollutants and their estrogen like effects have been implicated in diabetes, heart disease, thyroid dysfunction and fertility and AI disease doesn’t escape its noose (Gawda, Majka, Nowak, & Marcinkiewicz, 2017).

 In my recent Masters thesis I referenced that malondialdehyde (MDA) as suggested by others is a useful marker for determining the effects of stress on a system why?

 ‘Increased malondialdehyde (MDA) levels have been noted in overt and sub clinical hypothyroidism. As MDA levels reflect increased oxidation of lipids and may represent a suppression of CHO metabolism, this might be another useful marker for analysis when euthyroid serum values are recorded, yet hypothyroidism is suspected.

 Airborne pollutants create changes to reactive oxygen and reactive nitrogen species (RONS), which when increased, are pro-inflammatory and increase MDA via increased fat oxidation . Maybe the primary drivers behind AI action is part of the global response that decreases thyroid hormone communication, production and assimilation? An inability to regulate both blood sugar and utilise carbohydrate through the glucose-fatty acid/Randle cycle is a specific loss of function induced by pollution and thyroid inhibition. Thyroid is organisational, estrogen is a stimulator of growth and suppresses the organisational and protective actions of progesterone increasing growth and disorganisation (Peat 1992).

The strongest predictor for the development of the AI disease Lupus (SLE) is female sex with a female to male ratio of 9:1 (McMurray & May, 2003). Seems to be a pretty constant ratio with development of hypothyroid disease doesn’t it?

The markers below give a common overview of altered hormone levels shown in patients with Lupus. Once again the commonality of increased estrogen/estradiol and its stimulation of the pituitary hormone prolactin is observed. Suppression of the anabolic hormones and thyroid appears to be a key driver of the AI state.

Sex Hormone changes in auto immune disease (McMurray & May, 2003)

Sex Hormone changes in auto immune disease (McMurray & May, 2003)

In a previous blog, I suggested factors that could influence thyroid hormones and their appearance when tested. It might be normal for thyroid antibodies to persist being elevated for some time due to many factors which include use of T4 in isolation, excessive pollution, poor food choices, medical estrogens, lack of selenium and more. Again, blood tests may or may not offer a real time evaluation of thyroid status, which would be the main driver of resolving an AI state. Temperature and pulse rate to track thyroid hormone use and thyroid function at large is extremely useful. Maintaining energy, thyroid hormone and light exposure seems to be the most prudent action when it comes to having better conversations with the environment and what might a long term solution to resolving AI disease.

In part 2 I’ll elaborate on the problems associated with a reduced diet that promotes a decrease in function over time.

Sub Clinical Hypothyroidism

Strange, must-try exotic fruits!.jpg

I’ve seen a number of assumptions from doctors suggesting that there’s no optimal diet for improving thyroid function. If that were the case there would be no optimal diet for heart disease, cancer or autoimmune disease but there are many proposed guidelines of certain foods that should be avoided.

 If you want to slow down the thyroid eating plenty of cruciferous vegetables, fish oils and exposure to oestrogens (environmental pollution, contraception and other medical drugs) seems to inhibit thyroid function dramatically and large amounts of anti-thyroid (goitregens) foods are certainly linked with thyroid cancer. Often an individual’s perceived healthy choices can suppress thyroid function and therefore be resolved with nutrition alone. A functionally suppressed thyroid state that’s treated with thyroid hormone may not yield the best results.

 Sub clinical hypothyroidism (SCH) is an issue that divides endocrinology but when you look at the process of thyroid dysfunction there are some clear indicators that should suggest that it’s treatment would be the most sensible (but not the most money making) action in the long run. Let’s start with defining what SCH is.

SCH is usually defined as an asymptomatic state in which free T4 is normal but TSH (thyroid stimulating hormone or TSH is the pituitary stimulator of thyroid hormone) is elevated. If serum TSH is >10mU/L there is consensus that the patient should be treated with thyroxine because of the likelihood that the patient will develop overt hypothyroidism with subnormal T4 and because this degree of SCH predisposes to cardiovascular disease. When the TSH is in the range of 4.5 to 10 mU/L, there is controversy about the efficacy of T4 therapy (Lavin, N, Ali, Omar., Beall, M.U., Bhutto, 2016).

Although many people with most forms of thyroid disease often present with diverse symptoms due to the systemic effects of thyroid hormone action but are often ignored through reductionist observation. The table below lists most of the major actions of thyroid function and deficits created by a hypothyroid state.


Thyroid hormone is necessary for all aspects of organised biology.

Thyroid hormone is necessary for all aspects of organised biology.

Here’s a short history of some of the contrasting opinions on treating SCH. Biondi cites the original controversies of Wartofsky and Dickey (2005) who favoured a narrower TSH range (Wartofsky & Dickey, 2005), which was in contrast to the opposition to a lower TSH suggested by Surks et al. (2005) (Biondi, 2013).

 The latter authors stated ‘that there was little evidence supporting the treatment of SCH, citing a single small study by Kong et al. treating 40 women with SCH (Kong et al., 2002).  The main findings demonstrated that thyroxine treatment had no impact on lipids, energy expenditure, weight gain or composition despite decreases in TSH levels in the treatment group (8.0 +- 1.5 mU/L change from baseline -4.6 +-2.3 mU/mL compared to 7.3 +- 1.6  -1.7 +-2.0 mU/L in the placebo). However this study, perhaps like many others (Laurberg et al., 2011) (Surks et al., 2005), failed to assess the nutritional status of this small group of patients. For example, if calorific excess were present, these markers may show little change, as weight loss requires a calorie deficit.  Conversely if a patient were chronically undernourished through a low nutrient intake, attempting to enhance metabolic rate and weight loss with TH replacement may be negated when adrenaline, glucagon and cortisol are produced to regulate blood sugar levels.

 Problems associated with some of the smaller seemingly positive older studies, is often the lack of control groups for comparison. A smaller RCT (treatment n-22 control n-19) comparing treatment of subjects with biochemically euthyroid TFTs  yet clinical hypothyroidism with thyroxine, found the intervention no more successful than placebo (Pollock et al., 2001). Whilst the effect of placebo cannot be discounted, the study only focused on cognitive function and wellbeing, factors that are a limited component of thyroid function.  A friend of mine also pointed out that the use of T4 alone and female cohort with an increased weight some 20kgs over the control group are also problematic issues in studies like this.

 More studies trickle through that builds upon previous suggestions that measuring TSH is a poor way to accurately assess thyroid function, primarily due to the facts that stress, environmental pollutants and nutrition can cause biochemistry and in particular thyroid blood tests to present as normal. The problem with ignoring SCH is the following scenario.

 You have isolated or a number of hypothyroid symptoms such as weight gain, high blood pressure, high cholesterol, hair loss, fatigue, low libido, altered menstrual cycle, anxiety or depression, poor sleep, constipation, brain fog, inflammation of the brain, altered heart contraction, dry skin etc.

 Good news Mrs X you have normal thyroid function as your blood tests came back within the normal ranges. The symptom/s you have must be in your head. Here you have high blood pressure take this anti-hypertensive medication.

The pituitary should be considered a source of evaluation that could be useful but should be treated with suspicion. There are many factors that alter thyroid feedback which include the disparity between the enzymes in the pituitary (deioidinase 2 supports the conversion of thyroid hormone in the pituitary and can appear normal)  and other tissues, thyroid receptor and mitochondrial damage. Recent meta analysis and other studies support the role of treating SCH to prevent cardiovascular disease, high cholesterol, hypertension (Ochs et al., 2008)(van Tienhoven-Wind & Dullaart, 2015)(Udovcic, Pena, Patham, Tabatabai, & Kansara, 2017) (Sun et al., 2017) and there’s a strong possibility that hypothyroidism in the central nervous system in areas like the prefrontal cortex are associated with dementia and Alzheimer’s (Pasqualetti, Pagano, Rengo, Ferrara, & Monzani, 2015)(Davis et al., 2008).

Temperature, pulse and symptoms can be a useful indicator of function when bloods appear to support the notion of sub clinical hypothyroidism

.

 It’s worth suggesting that endocrinologists should be well aware of all of the factors that can create the perception of normal blood tests, especially when individual’s present with clinical findings of hypothyroidism as suggested above. My previous posts on assessing thyroid function through body temperature and Ray Peat’s well written post should also be considered an integral part of assessment of thyroid evaluation. The concept of SCH is really only related to the blood test, because the other findings should give the game away.  Treating SCH shouldn’t be problematic when a thorough understanding of nutrition and environmental stimulus are known, and the only people at risk from taking a gradually increased dose of thryroxine would be individuals at risk of an immediate heart attack who generally would  present with a certain set of symptoms.

If Broda Barnes, an MD in the last century found that his patients didn’t succumb to heart disease when taking thyroid hormone. Shouldn’t we be looking for the more global implications of health improvements? Rather than treat high cholesterol, blood pressure, blood sugar, menstrual irregularities, metabolic syndrome (and many others) which all have a substantial relationship with thyroid function, with many studies that show substantial improvements when treated with thyroxine. Call me a cynic but perhaps a more detailed understanding of nutrition, environmental pollutants and their effects on thyroid physiology is probably more challenging to integrate into practice than completing genetic analysis with the proposed mutation driving a specific dysfunction.

Seasonal thyroid fluctuations, biology and mood

 As you may have read from previous blogs, the thyroid, its pituitary stimulator - thyroid stimulating hormone (TSH) and the other thyroid hormones are heavily influenced by environment, nutrition and stress. Additionally these hormones can present as normal when relied upon purely by biochemical analysis from the blood. The seasons, differing temperatures, light exposure and effects of hibernation hormones and neurotransmitters can also be a key factor in the expression of adequate energy, organisation and coherence of an individual’s biology. We get sick more so in winter when our function is suppressed and the immune system is called upon to mount a response.

Tromp.png

S.W. Tromp Biometerology 1967.

“ The yearly influenza peak in the Netherlands, around February. Which may be related to the usually low humidity and wind-speed in this period, but which effect is probably accelerated by the decreased thermoregulation efficiency of the body as a result of the preceding cold months and the accompanying changes in the physico-chemical state of the blood such as y-globulin level.”

 Ambient temperature can have a significant effect on TSH production in as much as a colder environment increases TSH and warmer temperatures decrease TSH production and thyroid requirement. Observations have suggested a biphasic seasonal nature of TSH secretion, with increased TSH readings during winter time suggesting what could be a functionally hypothyroid or subclinical hypothyroidism which resolved during the summer months (Kim et al., 2013). As this stress increases throughout longer days of darkness, organisational hormones decrease, whilst stress hormones increase. If chronic enough, or in an unstable biology, stress can decrease the accuracy of TSH to predict a low thyroid state

 Light, both red and ultraviolet (UV) are well-known modulators of immune function, metabolism and mitochondrial production of energy or  adenosine triphosphate (ATP) (Wong-Riley et al., 2005) (Karu, 2010). These aspects of sunlight, exert their influence via enhancement of aerobic metabolism (at cytochrome c) and immunity enhancing via infra-red (NIR) and vitamin D synthesized by UV respectively.  The variation in light exposure as a consequence of daily sleep, darkness and seasonal variations present relationships that may explain the secretory patterns of TSH in healthy subjects. More than 100 years ago, thyroid function could be suggestively viewed via uptake of thyroid iodine levels in seasonal variations. (Fenger and Siedell 1913). Thyroid iodine levels rose during the summer in sheep, pigs and cows and decreased during the winter reflecting the variations in the need for TSH/TH production in healthy organisms. 

Seasons, Thyroid and Mood

 Depression is a known symptom of hypothyroidism and some studies have highlighted the need for a lower TSH value in the presence of depressive symptoms (Talaei, Rafee, Rafei, & Chehrei, 2017) (Hage & Azar, 2012). The former authors suggest a cut-off value of 2.5 mU/L for TSH as a point for treating hypothyroidism, which highlights the need for assessing symptoms as part of an effective strategy for diagnosing hypothyroidism. This compares to the attitude taken to expecting mothers where values should be decreased to compensate for hypothyroid states but in reality should be applied across the board.

 Relationships concerning seasonal variations of mood are well documented and decreased Beck mood scores are associated with the shorter days of winter (Harmatz et al., 2000). Seasonal affective disorder (SAD) may be a reflection of the increase in serotonin and melatonin and depression of thyroid hormone, which are increased by shorter days and in mammals are associated with hibernation. This aspect seems to be lost on those treating transient depressed states but light therapy does appear to be taken seriously these days. I would encourage anyone wanting more information on serotonin and mood to check out the extremely well written blog Against Utopia.

 As days become shorter and light exposure is decreased, influencing cellular function and metabolism negatively. The extended effects of melatonin from the shorter days can antagonise TSH secretion via its inhibitory action on TH, increasing prevalence throughout winter. Whilst fluctuations in TSH levels in response to seasonal changes are well-known to occur, these fluctuations are also under the influence of the nutritional and environmental factors that can suppress TSH values.

Wake me up when it’s spring?

Violent suicides increase with the onset of spring from March to May. I was trying to think why this might occur? After speaking to a friend recently about depression, they said that holding onto the feelings of a blanketed, safe, dark environment by being it home (in a somewhat hibernation like state), and gorging on boxsets or podcasts was easy to do and a comfort. I wonder if the shorter phases of darkness and increased light remove that blanket of increased serotonin and melatonin and the light itself might become a stressor that takes away that comfort? Those most at risk might explain this seasonal increase in suicides?

Ray Peat (1997) has discussed various aspects of stressors such as darkness, oestrogen-cold sensitive enzymes and nutritional factors affecting endocrine systems, adding an interesting perspective on hormone production and relationships with temperature changes (Peat, R. and Soderwall, 1972) (Peat, 1997)(Peat, 1972).

In states of undetectable SCH mediated by the stress, a hypothermic state may stimulate the adrenal stress system to compensate for a low-metabolic and decreased temperature state.  Activated compensatory stress response pathways may explain poorly detected hypothyroid patients. Decreased metabolic rate, lowered temperature and pulse rate are well-known signs of hypothyroidism. β adrenergic mechanisms involving increased catecholamine production such as adrenaline and noradrenaline (NA) can increase Tb and RHR. In my previous blog on body temperature, I explained how low temperature can be indicative of low thyroid function when blood tests appear normal.

A Bioenergetic Approach to Restoring Gut Function: Part 2

Copy of Your bowel function might be an expression of your biology.jpg

Oops - A bioenergetic approach to restoring gut function part 1 was almost two years ago, my studies got the better of me, I’m sorry. Following on from the information of how to restore energy and digestion by simply removing foods that are difficult to digest, promote endotoxin, decrease energy and digestion. Replacing them with easily digested, protective nutrients can negate the need for expensive, reduced testing and a supplement list that causes you to rattle as you stroll down the street. Much like the decreased need for stool testing, I have rarely recommended a food allergy or sensitivity test for the same reason that I haven’t used a stool test for many years (or had the luxury of a nice cash kickback from the labs I used to use). Why? Because these tests show the body in a stressed, energy wasting state that is prone to inflammation and reacts with many foods like dairy. Is it the food? No. Could it be you? It’s possible.

Metchnikoff.png

It’s not the dairy it’s you

Elie Metchnikoff suggested over 100 years ago that as putrefaction within the bowel occurs, function and immunity is compromised

 

Many clients have rolled into the office clutching their food sensitivity tests in a file, with dozens of other tests. Red bars, yellow bars, all highlighting so called problem foods. During bouts of stress (pollution exposure, psychological, under eating etc, excessive exercise, poor sleep) the body is prone to decreasing available levels of organisational hormones such as thyroid and progesterone. Usually the adrenal glands have to pick up the slack and compensatory stress hormones such as cortisol, glucagon, adrenaline and activation of serotonin (not a hormone) which  suppress thyroid and progesterone are perpetuated. This often creates a high sodium (salt) and magnesium wasting state and poor digestive function that facilitates increased sensitivity via increased serotonin and histamine levels. This also increases demand for vitamin C for gut mucosa maintenance and adrenal responses.

If this state is perpetuated increases in endotoxin (the by-product of bacterial metabolism and degradation ) burden the digestive system, liver, and can damage the gastrointestinal lining. Endotoxin levels are also  increasing through airborne environmental pollutants such as polycyclic aromatic hydrocarbons  from fossil fuel use and industry (Annamalai & Namasivayam, 2015), so it’s worth considering that some people in a high pollution area, with poor digestive function are at increased risk of presenting with food sensitivities. They get tested, part with their cash and told to cut out 20 foods that they eat on a regular basis. Problem solved? Well no, it’s an intervention that will have some success but it’s some distance of what the person really needs.

 To simplify some of the well-known digestive issues with two ends of the spectrum.

Your bowel function might be an expression of your biology.jpg

Restore function

Restore appropriate movement

Constipation – failure to go to poop daily, hard to pass.

 

IBS irritable bowel like issues. Loose often more than 3 times per day.

 

There’s plenty of reasons to link constipation with a low energy, functionally hypothyroid, subclinical or overt hypothyroid state (Lauritano et al., 2007) and increased bacterial overgrowth like SIBO or small intestinal bacterial overgrowth. The digestive system is energy and thyroid hormone dependant and restoring energy by supplying easily digested high energy foods can be a simple intervention with effective results.

Often when you dig into a person’s history, you might find that those with IBS like states often describe a period of constipation. It’s not impossible to suggest that sustained constipation will lead to increased endotoxin, serotonin and histamine that damages the bowel lining. When this environment is perpetuated by stress, poorly digested foods and low energy, the digestive system is maintained in a high stress state, sensitive and ready to reject any remotely objectionable substance. Any food can become problematic when the digestive system is over-burdened or sustains damage to enzyme producing structures in the villi and microvilli.

 If you follow the chart suggested in restoring gut function part 1, you should find yourself in a much improved state. If you need further improvement then the following factors have always worked well:

 

Constipation:

 Magnesium in forms such as chloride and glycinate or very useful for decreasing perceived stress and lowering the incidence of sensitivities and 400mgs to 1g is useful to experiment with and complements dietary changes suggested.

To restore bowel movement magnesium sulphate or Epsom salts will mobilise the digestive tract and I have found that clients if needed try half to a full teaspoon to grease the wheels.

Vitamin C is a great way of decreasing constipation. A few years back I would recommend a dose of 1-2 grams  but equally I feel adequate intake of orange juice will do a great job. The added benefit of orange juice (polyphenols) has been shown to decrease inflammation and endotoxin which is often present in both high fat and carbohydrate meals (Ghanim et al., 2010).

 

Cascara Sagrada If you need a good clear out to restart function then cascara is an extremely effective solution.


‘ An effective laxative (besides preventing inflammation) causes not only coordinated contraction of the smooth muscles of the intestine, but also adjusts secretions and absorption, so that an appropriate amount of fluid stays in the intestine, and the cells of the intestine don’t become water-logged.’ Ray Peat.

 

Caffeine seems a logical choice and the research on caffeine as a potent factor in the fight against cancer and neuro degenerative diseases such as dementia and Alzheimer’s disease is very positive. Coffee stimulates bowel function and like the suggestions above is useful to decrease the reabsorbed metabolites and toxins that may be instrumental in systemic inflammation. The aerobic/respiratory system is enhance and protected by coffee consumption, providing protection to the mitochondria (Eskelinen & Kivipelto, 2010).

 

Irritable bowel

Carrots I have posted about the power of grated carrot to reduce the irritated state many times and have seen some clients with over 20 years of IBS resolve with this simple addition. Carrots act as a natural antibiotic, lowering endotoxin and other bacterial end products (Babic, Nguyen‐the, Amiot, & Aubert, 1994) and bamboo shoots have the same effect. As increased bacterial issues stimulate endotoxin production the daily use of a carrot salad can be one of the simplest yet most effective tools that you can have to improve bowel function.

Bone broth, gelatin and glycine are also great for helping to support gastrointestinal mucosa, improve the brush border enzyme function and decrease the proinflammatory effects of eating tryptophan and iron rich muscle meats that can also irritate the bowel when excessive.

Mushrooms  when boiled also have a similar effect as the carrot by decreasing aromatase enzymes and estrogen  acting as a natural antibiotic.

I would challenge anyone who either has paid money for a food sensitivity test or who is thinking about it ,to simply try the suggestions set out in these two posts. Over the last few years I haven’t seen anyone who has failed to improve digestive function. Although sometimes other mechanisms involving hormones may need to be explored.

Body temperature and health

Most people are so confused as to what constitutes good health these days and when they turn up to my office in low metabolic states with digestion, sleep, energy, mood and other issues. One of the first things that they say is that they eat really healthily. If you throw into the melting pot the obsession with the keto diet, chronic calorific restriction (CR) or other modalities, those short term gains have turned into long term deficits. I’ve long opined that health in general terms can be defined by:

 

·      Good energy

·      Good Digestion 2-3 bowel movements per day

·      Restorative sleep

·      Balanced mood free of depression or anxiety

·      Desire for life, motivation, hobbies and interests

·      Healthy libido

·      Absence of pain

Humans are endotherms that regulate their temperature at 37 degrees centigrade.jpg

What does your body temperature suggest about your health?

Get cold…read on

I’ll also add to that list a warm body and the ability to generate efficient energy,  a phrase biologists might use is a state of negative entropy. Entropy is a state associated with decay and disorder and as entropy increases, equilibrium is achieved - where a state of no energy in and no energy out or death of a living system occurs. The basis for life and metabolism is governed by the enzymes. Enzymes function well in an appropriate temperature and in a medium that is neither too acidic nor too alkaline. Mammals and specifically humans are endotherms that regulate their temperature in  tight range at approximately 37 degrees Centigrade (C) or 98.6 Fahrenheit (Bicego, Barros, & Branco, 2007). The central compartment theory of temperature  suggests that the head and the core should maintain a relatively stable temperature, due to the rich vascular supply and that the periphery may vary some 2-4 C.  

In a recent study that I conducted I suggested that the peripheral and core temperatures should remain at a similar level of about 37 C . The suggestion that a decreased body temperature recorded in the head, might be the last place that you would see a reduction due to the large quantities of glucose that the brain uses to maintain function. It’s possible to suggest that the slowing of function in low energy and hypothyroid states might be observed initially in the trunk or core. The well documented symptoms of constipation, decreased heart rate, slowed contraction relaxation of the heart and arteries and reduced peripheral relaxation of tendons (Achilles tendon reflex) might appear in the trunk and peripherally due to the preferential oxidation of glucose initially. Due to the vast systemic implications of low thyroid function, many different paths of decreased function might occur, dependant on nutrition, environmental stimulus and other stressors. In my study I didn’t find this but what I did find is strong linear correlations between low body temperature in both the mouth and armpit, multiple low thyroid symptoms (mean 6.8 per subject) and yet normal blood values.

Humans are endotherms that regulate their temperature at 37 degrees centigrade-2.jpg

Thyroid hormone affects all aspects of biology

 

There are many factors that can decrease body temperature such as CR, fasting, estrogen, stress, pollution, over exercise and more. CR has been suggested as a mechanism for maintaining longevity but studies lack any conclusive evidence (Carrillo & Flouris, 2011) and a theory that a cold body, decreases metabolism, oxidation and damage therefore preserving tissues. Another emergent theory and results show in rodent studies, that mammals with a high energy intake, high metabolism and organised biology can increase life span (John R. Speakman et al., 2004) (J. R. Speakman, 2005). Think about this for a minute:

Calorific restriction makes the body cold, decreases metabolic rate  (via inhibition of thyroid hormone) and disorganisation of tissues. Entropy State

Adequate energy, maintains body temperature and organises tissues to function at their best. Negative entropy state.

From an evolutionary perspective fasting due to lack of food was a necessity. Fasting these days could be a useful tool, if you were prone to constant overeating but if your system lacks the flexibility to do so problems can occur. That’s not to say that calorie restriction for weight loss isn’t helpful but sustained CR in a system that doesn’t respond well might be counterproductive. Pollution has increased at a phenomenal rate clearly affecting physiology and hormones (Gore et al., 2015). Does it make sense that a so called detox diet, low in calories, protein, carbohydrates can enhance the function of detoxification, when liver function is energy and thyroid dependant? Skipping breakfast alone in some is associated with increased cortisol, glucagon and metabolic inflexibility (Jakubowicz, Wainstein, Ahren, et al., 2015) (Jakubowicz, Wainstein, Ahrén, et al., 2015). These factors can also decrease the mitochondrial uncoupling proteins which are responsible for increased body temperature.

Ageing is also associated with decreased metabolic rate, colder bodies and accepted increases in thyroid hormone stimulating values (TSH) (Laurberg, Andersen, Pedersen, & Carlé, 2005) . If symptoms of failing biology are present with isolated thyroid symptoms such as increased cholesterol,  , high blood pressure and sugar, cardiovascular issues and even cancer the acceptance of TSH and other thyroid hormone analysis to accurately predict hypothyroidism should be considered. Body temperature and metabolic rate was reliably used in the last century to diagnose hypothyroidism with qualitative analysis of symptoms and symptoms resolved with thyroid hormone treatment (Barnes, 1942) (McGavack, Lange, & Schwimmer, 1945) (Peat, 1999). Whilst thyroid is useful for restoring function, food and other factors can be used to restore and maintain function (previous blog on maintaining the aerobic system)

Certain nuances exist in temperature regulation that are dependant on acute or chronic exposure to stressors and a slowing down of the system through  a functionally, subclinical or overt hypothyroid state. In short term fasting, TSH is initially raised then decreases, negating thyroid blood tests. In the same manner the time frame of any stressor can dictate whether short or long term compensations of  the sympathetic adrenergic system is supporting the system. In well established feedback mechanism it’s known that as TSH increases so does cortisol and as body temperature approaches hypothermic levels (around 35C) cortisol, adrenaline and noradrenaline can increase body temperature as a protective response.

In a world where excess environmental and social stressors are ever increasing - it might make sense to maintain an efficient, organised warm body rather than reducing its function and heat.

Better gut health with less bacteria?

Can you have better gut health with less bacteria? There’s an old saying in the integrative health world that ‘ Death begins in the colon.’ These were the words of the 1906 Nobel science award holder Elie Metchnikoff, a Russian scientist who did much to elaborate on the mechanisms of embryology, immunology and other aspects of health and disease. These days there’s much that has been written about the micro biome and the suggestion that diverse microbes within the bowel are an important factor in health. How we need to eat plenty of fibrous and fermented foods for better health. But how true is this and are more bacteria necessary for better digestion and longer life? “The retention of faecal matter for several days very often brings harmful consequences. Organisms which are in a feeble state from some cause are specially susceptible to damage of the kind referred to.” (Metchnikoff & Metchnikoff, 1908)

Ok so you aren’t likely to die anytime soon from being constipated for several days, you might feel like crap (excuse the pun). But what if the repetition of constipation is over years? We have seen that hypothyroidism and constipation is clearly linked and can induce small intestinal bacterial overgrowth (Lauritano et al., 2007). An inability to remove the waste products is a particular burden on a stressed system.

"Not only is there autointoxication from the microbial poisons absorbed in, cases of constipation but microbes themselves may pass through the walls of the intestines."

This description of endotoxin and other bacterial end products damaging and permeating the intestinal wall is a well-known modern concept of leaky gut or intestinal hyper permeability. Metchnikoff’s describes the putrefaction (think fermenting mass of stinky stuff) of foods within the bowel that lead to the damage described in a permeable gut lining that allows bacteria and endotoxin into the blood stream.

There’s a theory that I have, as it’s clear that not all people have constipation. Many present with irritable bowel syndrome (IBS) like states, loose and perhaps a product of irritation induce by high serotonin and histamine (which by keeping to a minimum can also improve sleep and mood). It’s plausible to suggest that some people have already gone through a constipated phase induced by either a low energy or thyroid state, which may give way to a high adrenaline state over time. The lack of movement in the bowel for some can set the scene for future IBS reactions due to the accumulative damage induced by constipation, putrefaction, bacterial end products and increased irritation. Some clients have noticed that they previously went through a constipated phase before they arrived at their suggested IBS.

So if the current theme of recommending probiotics, raw and fermented foods is in vogue. What does that mean for the digestive system. I remember a newsletter from Ray Peat suggesting that animals born in a sterile environment generally live longer and have a higher metabolic rate. This in itself is a hard, near impossible feat to achieve outside of a sterile laboratory but consider this - Most babies are grown within a womb that does not contain any bacteria, as soon as they come through the birth canal and into the world at large. The bacterial management of life comes into play and had it come any sooner, may have had disastrous consequences. Other observations of Metchnikoff related to the longevity of birds, which have a high metabolic rate and limited intestinal flora -

‘Even in birds of pray which feed upon putrid flesh, the number of microbes in the intestine is remarkably limited. I have investigated the case of ravens which I fed flesh which was putrid and swarming with microbes. The droppings contained very few bacteria, and it was remarkable that the intestines had not the slightest smell of putrefaction. Although the opened body of a herbivorous mammal, such as a rabbit, gives off a strong smell of putrefaction, the body of a raven with its digestive tube exposed has no unpleasant smell. The absence of putrefaction in the intestine is probably the reason of the great longevity of such birds as parrots, ravens, and their allies.’

Metchnikoff also states that despite the absence of bacteria, their organisation and metabolism may be the primary driver for long health. Therefore if we were to keep bacterial interference at bay might we be better at living longer lives by improving our gut health? Our metabolism and cellular health is the key to prevention of many disease states. Extra bacteria may just be another factor that our immune system has to contend with and may be at the heart of autoimmune issues. From a comparative biology standpoint many other herbivorous animals don’t live as long as omnivorous animals. Horses, cows, and sheep live very short lives in comparison to other mammals that eat a wide range of foods. The main exception being the elephant, which has an extremely large intestine like other vertebrates.

Probiotics and fermented foods provide a mixed bag of research(Goldenberg et al., 2015). In many studies bacterial infections and digestive issues have not been resolved by probiotics. They do seem to be particularly effective at reducing bacterial/food poisoning cases and decreasing the diarrhoea like state by a day or two. Primarily this acts as a competing organism in the battle of the bowel and maybe why faecal implants have been shown to beneficial in the short term for some.. Even beneficial strains of bacteria such as lactobacillus can be problematic in excess due to the high levels of lactic acid leading to d-lactate acidosis, decreasing our gut health and overall wellbeing.

After all increased bacteria equals increased immune system responses and constant battles, for some there’s only so much that a faltering metabolism and immune system that one can take. Providing easily digested nutrients that limit bacterial growth and metabolites, that doesn’t burden a compromised digestive system seems prudent. In hypothyroidism gastric secretions such as hydrochloric acid are often lowered, further compromising digestion. Easily digested nutrients equals easily available source of energy and macronutrients.

To read more on how to combat these issues, to improve your gut health, digestion, mood and energy, this article is extended in the members’ area or there's also some information in this blog from 2017.

How to keep your energy chain maintained. Protective compounds.

How to keep your (electron transport) chain-2.png

How to keep your energy chain ( electron transport or ETC) running might not be something you think about, but if you are concerned about being healthier, this is an often overlooked area of maintaining health. It came as a huge disappointment to find out that the historical use of a false tooth compartment to hide cyanide tablets (for soldiers and spies) to commit suicide was pure fantasy. Although cyanide hidden in glasses appears to be more likely, the role of cyanide to induce rapid death is indisputable. We are at a time where industrial pollutants are at an all time high and cyanide being one of those pollutants, might not induce a theatrical foaming of the lips and contorted last throws of life (as seen in many an old war movie); it may induce a slower, less dramatic affect on cell function and efficient biology over time.

Cyanide is certainly ubiquitous in the industrialised environment but unknowingly for many, trying to achieve a ‘healthier’ balanced diet, cyanides are present in many foods favoured by the health conscious.

There are more than 2500 plants associated with cyanide content, these include almonds, millet, lima beans, soy, spinach, bamboo shoots, and cassava roots (which are a major source of food in tropical countries), cyanides occur naturally as part of sugars or other natural compounds. Cassava consumption (especially so in poorer countries) is associated with the neurological, irreversible disease called Konzo (Nzwalo & Cliff, 2011). Some other major sources of cyanide are:

Seeds/kernels of apples, apricots, plums, peach and nectarine, millet, almonds, flax seed, , spinach, sorghum gluten free flour like cassava often used to replace normal flours. Simply type in cassava poisoning into a search engine and you'll see some cases where dozens of people from the same meal have died from a so called bad cassava. Most likely it was the poor preparation and failure to remove the cyanide from the cassava that lead to these numerous deaths. In one case in the Philippines in 2005, 27 children died in such a manner.

Other cyanide sources include vehicle exhaust, releases from chemical industries, burning of municipal waste, and use of cyanide-containing pesticides (Jaszczak et al 2017) and the more obvious smoking.

Excess cyanide (ions) is able to disrupt the efficient production of energy that is produced through the electron transport chain/mitochondria (energy producing cells) where water, carbon dioxide and energy are end products. The loss of this function often creates a decreased ability to utilise carbohydrate effectively and the result can be an excess of lactate, which diminishes cell function further and creates hypoxia. Lactic acid seems to be getting some praise of late but it is the hallmark of inefficient energy production, as observed in the so called Warburg state seen in cancer (5). As cyanide levels increase cellular death occurs through increased lactic acidosis. This is the death throw that you see our actors who have crunched down on that mythical hydrogen cyanide capsule. It's also observed as a cause of death to the unlucky Private Santiago in A Few Good Men, where he has a rag with cleaning fluid, stuffed into his mouth creating a not to dissimilar occurrence.

[embed]http://gph.is/1hyjRwN[/embed]

You want the truth? You can't handle the truth but it might be that a combination of dietary cyanide and pollutants might not be as healthy as you think.

If there’s a ubiquitous source of cyanide and other pollutants in the environment does it make sense to have plenty of cyanide containing foods? Let’s not take this out of context. Here and there - having foods that have some levels of cyanide in should pose no problem to a healthy individual but what if your diet contains a regular supply and also contains plenty of vegetables that contain goitregens or foods that slow down thyroid function (and also contain cyanide) it may be problematic. Many people seem to promote a diet high in raw green vegetables, nuts, seeds, often low in adequate protein and often deficient in adequate energy/carbohydrate. In this instance the so-called healthy diet, in a highly polluted area becomes a burden not a provider of energy to promote optimal thyroid health, energy and liver enhancer (energy, detox, hormones etc.).

Chris Masterjohn’s report - Thyroid toxins, highlights the out of context suggestions of nutritional science evaluation of compounds in a test tube compared to a real world scenario.

The line that divides nutrients from toxins is often thin and equivocal. Since any given chemical may react in any number of ways in a test tube depending on the other chemicals with which it is combined, it is often possible to prove such a chemical to be both a nutrient and a toxin.

If a diet is to be considered healthy, it should meet the body’s energetic demands without reducing its function. A healthy energy chain ensures that carbohydrate is metabolised efficiently without an excess of lactic acid production.

The abundance of glucosinolates found in broccoli, cauliflower (and other brassica vegetables) and other cyanide like food sources combined with other environmental pollutants may pose substantial problems over time. Heavy metals like mercury, which are also increasing environmentally can decrease selenium and iodine uptake creating another algorithm for decreased function.

cell enhancers

cell enhancers

Caffeine can be considered a useful compound for preventing excess uptake of metals and may go someway to explain the anti-oxidant and other positive effects observed in neurological degeneration diseases such as Alzheimer’s and dementia (Liu et al., 2016). Other compounds like methylene blue can be seen in the next diagram that promote a better energy chain.

" As I have shown in my earlier days , one can knock out the whole respiratory chain by cyanide and then restore oxygen uptake by adding methylene blue  which takes the whole electron transport chain over between dehydrogenases and  O2 ."   Albert Szent Györgi

You can also reduce the risk of excess cyanides in foods through heating, boiling and other forms of processing but given that the zeitgeist is as raw, wholesome and as gluten free as one can be, it’s unlikely that this occurs in the upwardly mobile food neurotic.

A biochemical approach to decreasing muscle pain with food and hormones.

pain and hormones

pain and hormones

A biochemical approach to decreasing muscle pain is often the last place most people look and that includes many pain specialists. Modulating pain and hormones through food and other variables can create some impressive results. Aches and pains are a common theme in every day living. Some people seek to push themselves harder with excessive training schedules, others spend more time in a seated position and other factors contribute to tissue not responding the way that it should. Pain and the concept of nociception is a system of feedback for the body that is protective in essence. You touch something you shouldn’t; first pain kicks in to remove you from the painful stimulus (lasts less than 0.1 seconds), after that and depending on severity of damage second pain kicks in.

First pain and second pain (both reside in the anterolateral system or ALS) utilise different chemical messengers and another factor for this form of feedback is that other nociceptive factors like touch, visual, auditory and other sensations of stress can be part of the problematic feedback if not resolved. All of these have the capacity to interrupt optimal motor control and functioning of joints and soft tissues and affect hormone profiles. Even a bad smell can create neurological chaos.

Another less well known aspect (in therapy based settings) of disruptive function in muscle tissue are the effects of hormones that may lead to decreased feed back and be responsible for pain. Hypothyroidism affects muscle tissue via energy and neurological deficiencies.

Hypothyroidism results in

Slower peripheral and central nerve conduction velocity Lower body temperature is a factor creating slowed velocity Decreased active cell transport in the cerebral cortex Decreased flux of sodium and calcium for contraction/relaxation Poor production of energy for contraction/relaxation Decreases depolarisation of action potential

cold body

cold body

In a nutshell a colder, slower body leads to a decreased   coordinated body that has a hard time contracting and relaxing muscle tissue. This can lead to increased incidence of injury and pain.

A slowed heart rate is a sign of hypothyroidism and the bradychardia (slowed heart rate) should serve the purpose of describing the decreased rate of function throughout all muscle tissue. Thyroid hormone can improve both rate of contraction and relaxation in both fast and slow twitch muscles but also exerts a cardio protective role on blood vessels and bowel function via smooth muscle tissue. The documented symptoms of hypertension and constipation along with the neuromuscular actions tend to resolve with adequate thyroid hormone (Gao, Zhang, Zhang, Yang, & Chen, 2013).

Prior to initiating thyroid therapy it’s essential to rule out functionally hypothyroid states induced by diet, stress, excess exercise and other environmental factors. Many clients often present with lowered temperature, with cold hands, feet and nose, altered bowel, sleep and emotional function, which can often be resolved with appropriate energy and decreased intestinal irritants.

Chronic pain increases cortisol production which decreases thyroid hormone production (Samuels & McDaniel, 1997) as does fasting or calorie restriction which induces a decrease in available T3 (thyroid hormone) (Hulbert, 2000).

This gives us two approaches 1) to reduce pain with appropriate therapy and to ensure that adequate energy modulates the suppression of excess cortisol and increases available thyroid for tissue organisation and recovery.

Hormones also affect tendons; diabetics and poor insulin profiles appear to create disorganised tendon structure but this may be a factor related to decreased available thyroid hormone. Hypothyroidism decreases available T3 within tendons, which can decrease growth, structure, and collagen production and create hypoxia of tissue leading to calcification.

Estrogen, although necessary for growth of tissue can often be found in excess creating problematic growth. Estrogen is also well known to decrease thyroid hormone and can provide an explanation why more females then men tend to be hypothyroid. The decrease in both thyroid hormone and progesterone can increase muccopolysacharides, which increase pressure in tissues, creating puffy, oedema like states. The swelling can be linked to many pain states which include carpal tunnel, which can be resolved with progesterone and thyroid in the absence of physical therapy. Progesterone also appears to induce myelination of nerves (surrounds and allows nerve conduction) and decreases inflammation (Milani et al 2010).

Energy production remains  a most potent form of therapy for decreasing pain, optimising rehabilitation and restoring tissue function.

Poly Cystic Ovary Syndrome - inheritance, environment and stress. Recently I took on a client who was diagnosed with polycystic ovary syndrome (PCOS), a slightly wayward insulin profile and the ‘best practice’ of oral contraceptives and Glucophage (metformin- blood sugar regulating drug) were suggested. My client had started bleeding daily and was informed that this was normal for three months but would help out with PCOS and weight gain. However this seemed at odds with my current knowledge and experience of biology and endocrinology. There are plenty of studies highlighting the diabetes inducing effects of estrogen and oral contraceptives.

Glycemia constitutes a fundamental homeostatic variable, and hence its alteration can lead to a number of pathophysiological conditions affecting the internal milieu of the human being. Since the early 1960s, the intake of oral contraceptives has been associated with an increased risk of developing disorders of glucose metabolism.(Cortés & Alfaro, 2014)

Is best practice the efforts of a global network of doctors or simply a corporate led strategy? Don’t get me wrong; the world is full of competent, passionate and well-meaning doctors who signed up to help others. But the concept of both best practice and clinical governance seem a utopian ideal when those that are responsible for drug development are companies whose primary function is to make as much money as possible, without appropriate direction.

Joseph Dumitt in his book Drugs for Life (2012) highlights that there hasn’t been a scientist at the head of a pharmaceutical company for many years and their direction being driven by economists and marketers. As there are many examples of absolutist statements regarding drugs and their positive effects on health that lack congruence over time, you’ll forgive me for sounding like a conspiracy theorist. How about hormone replacement therapy (HRT) for better health despite its negative outcomes related to cardiovascular events or cancer? Or statin therapy for decreasing unnecessary risk factors based upon skewed data and early terminated trails with no public access to trial data (Lorgeril & Rabaeus, 2016)?

Back to PCOS. I have written previously about the effects of metformin and its use in gestational diabetes, and the problems it poses trans-generationally. It’s possible to suggest that the failure to act with appropriate biological interventions perpetuates the cycle of acquired traits from parents that are passed to offspring, treated ineffectively and generations of reproductive (and other tissues) tissue conditions continue without being resolved.

The biologist Jean Baptiste Lamarck's fourth law stated:

“ Everything which has been acquired..or changed in the organisation of an individual during its lifetime is preserved in the reproductive process and is transmitted to the next generation by those who experienced the alterations. “

It's worth pointing out that this is not isolated to the female of the species as the factors below have been shown to be instrumental in reproductive issues (testicular dysgenesis, hypospadias etc) in males.

The environment has been shown to be instrumental in the development of reproductive tissue disorders, diabetes and cancer but more emphasis is placed on the individual and their food choices rather than acknowledgement of industrial responsibility. Positive associations between levels of polychlorinated bisphenyls (PCBs), pesticides, polycyclic aromatic hydrocarbons (PAHs) and dichlorodiphenyldichloroethylene (DDE) have been confirmed in multivariate data analysis (Yang et al., 2015). Relationships between increases of luteinising hormone (LH) PCO, hyperandrogenism, annovulation, insulin resistance and pollutants are significant and may add to issues of detection, due to the subtle long term perturbations that often affect endocrine function. Stress, other pollutants and medications contribute to further problems that burden not only reproductive tissue but also other organizational hormones such as thyroid hormone.

PCOS is defined medically by the following: One of the main problems of treating PCOS with contraception is the many studies that clearly show a relationship between estrogen and decreased insulin sensitivity (Godsland et al., 1992)(Cortés & Alfaro, 2014). Progestin’s, the synthetic version of progesterone, also pose many problems but this has not deterred the inclusion of estrogen and progestin contraceptives as another inappropriate form of treatment. The burden of estrogen induced by the sources suggested above comes at a cost and it’s well known that an excess of estrogen can suppress thyroid function (thyroid is necessary for detoxification of estrogen and another organisational hormone progesterone.

Both thyroid and progesterone are known to improve insulin sensitivity and can create beneficial changes to disorganised tissue induced by an excess of estrogen. Thyroid nodules and uterine fibroids appear to be intimately linked by an excess of estrogen (Kim et al., 2010) and suppression of thyroid tumours can be achieved by thyroid stimulating hormone (TSH) suppression by thyroxin supplementation (Grussendorf, Reiners, Paschke, & Wegscheider, 2011). An old rambling on thyroid nodules and fibroids.


Breaking the cycle requires interventions that address inheritance, environment and individual stressors. Strategies that involve adequate nutrition that build biology not reduce it, use of protective compounds like progesterone, thyroid and adequate carbohydrate can be of great benefit. Although this stands in contrast to the best practice of contraception, blood sugar medication and poorly thought out nutritional advice of restricting carbohydrates. As the environment appears to drive most of the increasing numbers of issues like PCOS, it becomes important to increase robustness, restrict exposure to what we can control and become more adaptable to what we can’t.

Sleep, stress, sugar. Eat sugar for better sleep.

Onset of sleep

Onset of sleep

Can you improve sleep and decrease stress by eating sugar for better sleep? If you put sleep, stress and sugar in the same sentence, most people think they have already put the three together with something like; too much sugar causes stress and affects your sleep. If you read on you should find yourself advantageously aware of sleep biology and why consuming sugary foods before sleep, and indeed if you wake up are the answer for a deeper nights sleep.

Ah a good nights sleep. You remember one of those don’t you? As a father to 3 children I have had my fair share of sleepless nights but a recent 11 hour sleep whilst my kids slept for 12 hours, recently reminded me of why everyone should strive for better sleep and the common approaches that people tend to fail to implement. A couple of years ago I studied a short course on the neurobiology of sleep with the University of Michigan and I found it useful as it correlated with aspects of serotonin function that Ray Peat (7,8) had talked previously talked about.

Generalisations of sleep biology phases are:

Sleep latency - Getting your sorry arse to sleep

NREM sleep - Keeping your sorry arse asleep

REM sleep - Deep arsed sleep

Wakefulness - Wake your sorry arse up

One of the primary driving factors of the onset of sleep or sleep latency is the production of adenosine. Caffeine is a well-known antagonist of adenosine and therefore many a wise word about not drinking caffeine after 3-4 pm as it has a half-life of 6 hours are well heeded (yes I know there are some of you that metabolise caffeine really well after that time with no impact on sleep, STOP SHOWING OFF).  Avoiding caffeine though out the day isn’t necessary and caffeine is a widely mis-understand compound that shows many beneficial effects, if you follow the rules for its consumption.

Often there is much focus on the role of melatonin and sleep induction and structures like the suprachiasmatic nucleus and waking. Melatonin does indeed promote sleep but so does adenosine and I think the supplementing of melatonin misses key biological functions that induce sleep more effectively and without the negative effects associated with its use.

Serotonin and melatonin confusion

Sleep wake compounds

Sleep wake compounds

Just like the holistic health practitioner that suggests that coffee causes adrenal fatigue (it doesn’t but that’s another blog by itself), some practitioners recommend the use of 5HTP - tryptophan supplements (tryptophan converts to serotonin) for better sleep but this is misguided for the following reasons. It’s true that melatonin is a hormone of sleep and that it is derived from serotonin and that serotonin has a small but limited role in inhibiting the cholinergic system responsible for keeping you in an alert, thinking state. In the diagram below and born out of many studies is that serotonin is a powerful compound of wakefulness that synergises with histamine and the histaminergic system to bring you out of the deeper REM sleep, and start the process of waking you the hell up. The diagram from Brown et al (Brown, Basheer, McKenna, Strecker, & McCarley, 2012) highlights the complexities of the sleep wake compounds but also useful for highlighting serotonin's role (5HT) in the excitatory waking state. It’s also a great overview of the many areas and compounds that aren’t addressed in this blog. One thing that should become clear is that the neural structures controlling sleep are many and so are the interactions between hormones and other compounds of wakefulness. My advice below is not complete but merely a reflection of some of the simple changes that you can do (and which I have done with many clients) to create better sleep and recovery. 

Here are a few pointers on serotonin and melatonin.

  • Many people are aware of the fact that at least 95% of the body's serotonin is produced in the intestines - namely the enterochromaffin cells.

  • People associate serotonin as a hormone of calmness. 1) It’s not a hormone 2) well known side effects of serotonin excess are insomnia and anger.

  • Serotonin induces spasticity of the colons smooth muscle tissues

  • Eating excess muscle meats increases serotonin (as does eating poorly digestible foods), inflammation and can contribute to increased wakefulness by synergising with histamine.

  • Melatonin may be implicated in seasonal affective disorder due to increased levels in darker winter days. Sunglass wearing may pose similar issues (Alpayci, Ozdemir, Erdem, Bozan, & Yazmalar, 2012)

  • Supplementation with melatonin during the day can induce disruptive changes to fertility and also suppress thyroid hormone (Creighton & Rudeen, 1989).

  • Peak concentrations of thyroid stimulating hormone (TSH) occur at night and might be suggestive of thyroid hormone suppression induced by melatonin and other hormones. The pituitary responds by increasing TSH to bolster thyroid hormone supply.

Of course there are other compounds which include acetylcholine, GABA, oxycretin, histamine and many other areas of the central nervous system that could be mentioned but I have tried to stick to the mechanisms that can be changed and promote change in a short space of time.

If you find it hard to drift off, these are my suggestions as to why this might happen:

  1. You are eating foods that promote intestinal inflammation and increase serotonin and histamine.

  2. You are exposed to excess stimulus such as blue light, Wi-Fi or other source.

  3. Your blood sugar levels are not balanced and promote the stress hormones that liberate glucose from stored fats and proteins - adrenaline-glucagon-cortisol.

If you wake up at night the following might be also be an issue

  1. You are eating foods that promote intestinal inflammation and increase serotonin and histamine.

  2. Your blood sugar levels are not balanced and promote the stress hormones that liberate glucose from stored fats and proteins - adrenaline-glucagon-cortisol.

Point 2 may be a significant factor for many people and available efficient glucose production may be one of the most under-rated factors in both the onset of sleep and maintenance of sleep. Waking up to urinate at night is a feature of the diabetic like state. Poor blood sugar regulation requires, that instead of relying on blood and liver glucose stores, the stress response be relied upon to liberate energy from stored fats. This is an inefficiency that requires a stressed state. You should not be waking at night to go for a pee.

Morning Cortisol profile

Morning Cortisol profile

You can see from the average nighttime cortisol profile that cortisol generally starts to rise around 2 am, steadily increasing prior to the onset of waking. If your ability to regulate blood sugar levels is compromised this can increase the burden to blood sugar regulation and increase waking further. The REM phase of sleep uses a similar amount of glucose as the waking state.

Here are some useful tips that I use with clients to promote better sleep and recovery.

  1. Take a look at the previous post on resolving digestion issues. This helps to take away some of the factors related to serotonin and histamine excess.

  2. If you are exercising hard, low carb, busy parent or whatever form of stress and therefore don’t manage your blood sugar levels, you don’t manage your sleep. If you struggle getting to sleep a sweet drink like milk and honey (yes the old wives tale works like a charm). A glass of fruit juice with gelatin is also good. Any pattern with something with sweet with a little protein/fat is useful.

  3. Add some salt - increased stress burdens the adrenal glands, usually though thyroid hormone suppression. Salt is wasted in this state and so is magnesium. Salt spares magnesium, so adding a little salt also helps magnesium regulation.

  4. If you wake during the night. This can be common when trying to resolve these issues as liver function and hormone regulation take a little time to adjust. Therefore having something sweet by the bed can help to help you re-enter sleep. Squeezy honey tube or pouch of juice with straw I find useful so that the juice goes straight down rather than covering my teeth.

  5. I have often found that progesterone and thyroid play a key role in sleep and many clients have benefitted from resolving the states of low progesterone/thyroid, which may not have resolved with food alone.

  6. Optimal blood sugar regulation often starts with eating breakfast to decrease adrenaline, glucagon and cortisol (Jakubowicz et al., 2015)(Levitsky & Pacanowski, 2013). Drinking a kale smoothie or coffee on an empty stomach is not the best way to break your fast and set up the day.

  7. Of course aspects of sleep hygiene related to no phones, WI-FI etc goes without thinking and go as far as turning your router off at night.So armed with some facts that you can decrease stress and improve sleep by eating sugar in the right amount, you can go and experiment for yourself.

Is testosterone replacement therapy necessary?

Is Testosterone replacement therapy (TRT) necessary or symptom chasing? [embed]https://www.youtube.com/watch?v=KC0-xL0JVrI&feature=youtu.be[/embed]

In a world where it is increasingly normal to be convinced that we fall into a risk classification, need a treatment and can convince our doctor accordingly, negating any experience that he or she might have. The marketeers and economists that run pharmaceutical companies are doing a great job of increasing profits. Before we keep looking for the next wonder treatment we should take stock of what food and exercise can do.

Testosterone can be increased by some very simple strategies such as:

  1. Having adequate liver and vitamin A in the diet to assist in the conversion of cholesterol to pregnenolone - the base hormone responsible for production of testosterone and other androgens.

  2. Ensuring that adequate energy and thyroid hormone are available to maintain communication of the hypothalamic- pituitary- (signalling centres for hormone production-brain to testicles) gonadal axis.

  3. Understanding stress, sleep and interactions between excesses of estrogen and their impact on testosterone production.

  4. Less understood but increasingly keeping mobile communication devices out of pockets and bags that are close to reproductive tissue, including females (ovaries, endometrium etc), appears to be a pragmatic approach in the future. Steroid producing tissues have increased production of problematic compounds that may be prone to damage.

Here's some of the technical aspects to the situation that are taken from a recent assignment as part of my masters degree..

Introduction

Testosterone is a hormone found in both males and females but is the major reproductive hormone in men that also has a variety of other beneficial functions for maintaining physical and psychological aspects to health. Testosterone levels may decrease with disease and/or be part of an age related decline of output. The use of testosterone supplementation has increased substantially in recent years counter these states, primarily due to increased marketing as an agent of change for energy, strength, fat loss and sexual function. Whilst its use appears beneficial in some areas, caution has been recommended on the effects of T supplementation use and it’s effects on the cardiovascular system.

 Diagnosis

Testosterone (T) is the most important androgen found in males and produced primarily within the testes, when low it is defined as hypogonadism. Hypogonadism is classified as either primary, derived from the testes or secondary, which involves the hypothalamus, pituitary or derived from illness or disease. A low serum testosterone (<300ng/dL) is suggestive, but not definitive of hypogonadism and measurements of luteinising (LH) and follicle stimulating hormone (FSH) is used to establish a primary or secondary diagnosis (Crawford & Kennedy, 2016). A worry trend is that despite striking increases of testosterone prescription a substantial amount (approximately 29% in this review) of patients often fail to have their levels checked prior to undertaking testosterone replacement therapy (TRT). (Corona G, Rastrelli, Maseroli, Sforza, & Maggi, 2015). Additionally only 45 % had their testosterone levels checked during or post TRT intervention.

Low testosterone and cardiovascular risk

Previous studies have highlighted an increase in all cause mortality associated with low testosterone levels in men (Araujo et al., 2011). Conditions that increase risk of mortality related to low testosterone are increased abdominal obesity, inflammatory biomarkers, dyslipidaemia, diabetes mellitus and metabolic syndrome. However the diagnosis of an isolated low testosterone level should be qualified by ruling out other potential diagnosis such as long-term illness, nutritional deficiencies and other endocrine issues such as subclinical or overt hypothyroidism.

Testosterone supplementation and risks

A number of studies and meta analysis have demonstrated a number of beneficial effects of TRT which extend to increased sexual satisfaction, muscle mass, strength mood and metabolic function (Corona G et al., 2015) (Gagliano-Jucá & Basaria, 2017). However the suggested risk to increased CV adverse events have appeared vague in many studies and previous extrapolations/anecdotes between men having increased levels of testosterone (and therefore increased cardiac risk) and females having less testosterone and more oestrogen were not just problematic but incorrect. Many studies have correlated low testosterone to low biomarkers of health and increased cardiovascular disease (Pastuszak, Kohn, Estis, & Lipshultz, 2017) (Kloner, Carson, Dobs, Kopecky, & Mohler, 2016).

TRT reductionism and treating symptoms

A comprehensive review of the data compiled by Oskui et al (Mesbah Oskui, P., French, W.J., Herring, 2013) described the major CV implications of TRT which can be observed below. The authors draw attention to previously conducted studies, that did not show any relationships between low levels of testosterone and CV risk and suggest that both the subfraction of testosterone (Total T compared to Free T) and method of analysis for CVD were inappropriate and therefore unreliable for inclusion. 

Cardiovascular analysis Studies Major findings Association between T and mortality 8 8/8 studies found relationship between low T and increased all cause and CV mortality. Type 2 DM 6 6/6 studies showed improved insulin sensitivity through HOMA-IR/HgA!c and improved blood glucose Cholesterol 3 2/3 studies found no change to LDL/HDL from TRT Markers of inflammation (primarily C reactive protein CRP) 8 4/8 studies found reduced CRP Intima media thickness 8 8/8 found an inverse relationship between low T and IMT

The above studies reviewed by the authors, established a link between low levels of testosterone and increases in mortality (all cause and CV), insulin sensitivity and increases in intima media thickness that are resolved by TRT. Yet markers for lipids and inflammation markers such as CRP are less convincing. Hypothyroidism is related to low testosterone and hypogonadic states mainly through hypothalamic-pituitary dysfunction. Treatment of hypothyroid and subclinical hypothyroid states also resolves low testosterone and hypogonadic states, decreases intima media thickness, improves insulin sensitivity and decreases lipid levels (Crawford & Kennedy, 2016), (Krassas, Poppe, & Glinoer, 2010),(Donnelly & White, 2000) (Gao, Zhang, Zhang, Yang, & Chen, 2013). Is TRT the correct therapy for many males, given a) the rapid increases in often undiagnosed and prescription and b) when hypogonadic states, that have similar (cardiac) manifestations and are improved beyond the effects of TRT, are resolved with thyroid hormone?

Another factor concerning reliability of the studies used in previous meta analysis is the size to determine true risk between CV adverse events and TRT (Onasanya et al., 2016). The authors suggesting that to achieve a two-sided p value of 0.05 and power of 80% some 17664 participants would need to study to clarify any relationship. Observational data conducted over 5 years suggested that control groups treated with testosterone in short term had a lower mortality (HR 0.88 95 % CI 0:84 - 0.93) than controls (Wallis et al., 2016). From the meta analysis and other studies discussed above both age (>65) and predisposition to existing disease states may indicate the likelihood of adverse CV events when treated with TRT.

Another draw back of meta-analysis is the inclusion of data and bias produced by pharmaceutical companies that may not be adequately reflected or assessed. Much like cardiovascular end point studies being scarce. Testosterone studies that are funded by financial interests are usually in place to validate the benefits of TRT and fail to evaluate CV adverse events as end points. The increased adequate sample size needed to validate the safety and efficacy of this treatment often increase cost and decrease profit margin over time. The many studies that have been conducted so far, show much smaller sample sizes and a wide range of TRT delivery and dosing.

In a recent case crossover analysis that is not included in any current meta analysis, Layton et al (Layton et al., 2018) found a unique association between testosterone injections and short term cardio (and cerebrovascular) events in older men. Increased associations with myocardial infarction and stroke, post testosterone injection showed odds ratio (OR) were increased for all outcomes, OR =1.45 (95%: CI 1.07, 1.98).

Summary

Testosterone replacement does appear to have many positive effects on a number of markers related to cardiovascular health which include sexual performance, increased muscle mass, metabolic health, physical performance and decreasing mortality in a younger population. However, despite the many benefits of TRT the use of this therapy may have significant risk in late onset hypogonadal states, in ages >65 years of age, those susceptible to conditions associated with erythrocytosis and an association with acute cardiac events exists. It remains essential to ensure that not only adequate analysis of hypogonadal states are present but to ascertain if low testosterone levels are merely a symptom of other endocrine disturbances, such as hypothyroidism which has striking similarities to low levels of testosterone.

Alongside myself, scars may be one of the most under appreciated and neglected structures, when it comes to assessing aspects of an individual's pain and movement limitations.   For many people, which include physicians, surgeons and often the owners of said scars, there’s an acceptance that the scar has healed and is not involved in any process of pain, strength or movement dysfunction. Dr’s and surgeons often assume that time enables optimal healing and patients simply forget about the previous trauma. Time may be a great healer but the healing is only partial - the nervous system always remembers. Writing this, reminds me of a client who had filled in all historical injury and trauma that he had experienced on my intake forms, which might have been a factor in his chronic back pain. It wasn’t until he took his top off and under questioning revealed that he had  donated his kidney to his brother some twenty years ago. It wasn't a big deal though as it was twenty years ago apparently.

This sequence of events has been summarised as homeostatic, inflammation, granulation and remodelling phases (1) which are undergoing symbiotic relationships with other structures and dependant on energetic, endocrine and other functions of the individual, which often depend on environmental stimulus. During the granulation and proliferation phase, sub-phases, which include collagen deposition, remodelling of blood vessels and tissues occur. It’s likely that during these phases the health and energetic response of the individual will dictate the capacity to regenerate and may also influence the layers of dysfunction that are present with scar tissue.

“ In childhood, wounds heal quickly and inflammation is resolved, in extreme age, or during extreme stress or starvation, wound healing is much slower and the nature of inflammation and would closure is different. “Ray Peat.

Unsaturated vegetable fats, serotonin and estrogen promote collagen synthesis and resulting fibrosis and keloid scars are associated with these states (3). Perhaps the capacity to organise energy and regenerate are instrumental in decreasing the associated dysfunctions that can be found in all scar tissue? Most Drs that I have spoken to just assume that after 12 weeks the scar has generally healed and that normally activity can be resumed. As a rule, there is no thought given to mechanical, pain sensitising or emotional constraints induced by the presence of the scar. It’s generally accepted that most scars have 80% tensile strength of the previous structure, but again might that too be a product of the quality of healing available to the individual?

“ The amount of disorganised fibrous material formed in injured tissue is variable and depends on state of the individual and tissue situation. “

In hypothyroidism, high levels of the pituitary hormone TSH (thyroid stimulating hormone) are known to stimulate fibrosis (1) Maintaining adequate thyroid hormone production promotes DNA transcription, optimal energy production, carbon dioxide production and probably decreases the proliferative effects of 'estrogenic' states that can be attributed to keloid scar formation.

The bigger the scar, the more likely the associated dysfunction? Perhaps the more disorganised tissue that exists, the increased likelihood of fuzziness between the central nervous system and output to structures associated with that scar. In scar tissue that has not been assessed or treated, it's relatively easy to induce weakness or stress to the surrounding tissues by a variety of stimulus which might include thinking and different types of pain,  touch or vectors of stretch that create neurological chaos or threat to to the individual.

Good therapy should allow for conversations between the clinician and patient that create stimulus that may (or may not) affect the output of surrounding structures associated with the scar. Poor feedback mediated by the scar might involve the following:

Emotional: Aspects of recall of the event that the individual finds upsetting.

Nociception/pain: First and second pain, visual or auditory, crude/fine touch, tickle/itch temperature, stress or recall od suffering responses to stimulus. (Involve pain feedback related to spinothalamic, spinotectal, spinohypothalamic and spinomesencephalic tracts)

Mechanical: Pressure, rebound, stretch, joint mechanoreceptors and other responses to tissue and structures. (Related to Golgi, Pacini, Ruffini and other dorsal column feedback pathways.)

Improving the optimal healing of scar tissue might involve aspects such as adequate carbohydrate, proteins, sunlight (or red light), carbon dioxide, thyroid, progesterone, vitamin A and E. Avoiding phytoestrogens and low carbohydrate diets would also be prudent.

Despite optimised nutrition and endocrine function, it’s likely that many scars leave some artefact that prevents the nervous system communicating with tissues. C - sections, episiotomies, appendectomies, laparoscopies and most surgeries, injuries or trauma leave a trace that needs to be resolved with the right therapy. Inhibition can be purposeful but restoration might need a little nudge from therapies like proprioceptive deep tendon reflex (P-DTR).

Sunlight, health and cancer

The more you read, the more holes you find in many theories.

The more you read, the more holes you find in many theories.

Increasing sunlight exposure increases an individuals health and decreases cancer risk. In the last year or two I remember reading a quote from a professor of dermatology at a university in the U.S. who stated, “ There is no amount of sun that is good for the skin.” Clearly said professor skipped basic biology in secondary school or has had a lifetime of examining patients with excess PUFA (polyunsaturated fatty acids) in their diet, which is associated with increased incidence of skin cancer (there’s also a hopeful possibility that he was quoted out of context but I live in hope). Sun and skin cancer are clearly linked. Or are they? It doesn’t appear so clear cut. I first became interested in light around 2009 and its benefits to health after reading Female Hormones in Context by Ray Peat. His suggestions that sunlight can, “cure depression, improve immunity, stimulate our metabolism, while decreasing food cravings and increase our intelligence, ” (Peat, 1997) intrigued me to gain a deeper understanding.Whilst I was aware of the harms of an excess of UV light, which can damage skin but is essential for increasing vitamin D levels. The far-reaching benefits of the spectrum of red and orange lights were unbeknownst to me.

Seasonal affective disorder or SAD is well documented and the mechanisms may be due to a number of factors such as increases in serotonin and melatonin. People generally get sicker and more depressed in winter and light therapy appears to be a useful tool in overcoming some of the symptoms associated with mood, energy and immune system related issues. If light is so harmful, why is it we often need more in these times and why has sunlight become so vilified?

Sunlight appears to get a bad rap in an ever increasingly reductionist causal relationship, in as much as sunlight causes skin cancer. Therefore wear sunscreen and avoid it. However current literature suggestions are along the lines of; “Wearing sunscreen increases sun exposure and increases incidence of melanoma and skin cancer.” Like many other approaches this A to B inference neglects to mention other pertinent mechanisms that can be attributed to increased incidence of cancerous states.

Cancer is a well known metabolic disease that can occur when specific effects to cells, namely mitochondria and the electron transport chain (ETC - often termed respiratory defects which allows problematic features of metabolism to occur, increasing damaging compounds). Cancer can be a feature of poor differentiation. Damage to tissues can often require new tissue to be formed. If an architect informs the site manager how to build the structure from just the blueprints without appreciation of the surrounding land and features, you can’t always guarantee success of completion.

Promoting better conversations between structures     

Vitamin A - promotes cell differentiation (this is very important when damaged tissue is rebuilt), improves immune system function and optimal hormone function. A meta analysis in 2016 highlighted vitamin A’s protective functions and usefulness in protection against skin related disease such as melanoma through inhibiting malignant transformation and decreasing tumour size and improving survival rates (Zhang, Chu, & Liu, 2014). It’s important to note that retinol from liver sources is the effective compound in this action and not carotenoids. Other findings such as anaemia are synergistic with decreased vitamin A levels due to its critical role in the immune system and fighting infection (Semba & Bloem, 2002). Vitamin A has similar actions to organisational compounds such as progesterone and thyroid.

A question worth exploring - Does a vitamin A deficiency decrease differentiation and lead to a potential increase in cancerous type states when exposed to UV light?

Estrogen

Estrogen has been implicated in many cancerous states, primarily due to its role in tissue proliferation. When unchecked by levels of progesterone, it can be responsible for unwanted tissue growth and mutagenicity (Mungenast & Thalhammer, 2014) (Troisi et al., 2014). Levels can be increased due to external sources in the environment and through increased conversion of testosterone in adipose tissue to estrogen via aromatase in both men and women (Skakkebæk, 2003)(Cargouët, Bimbot, Levi, & Perdiz, 2006). The potential increases in cancerous states such as melanoma due to modulation of estrogen might be an easy target for excess levels of U.V. light to exert a negative influence in susceptible tissues. Therefore keeping estrogen low and utilising estrogen lowering strategies through food choices and avoidance of certain compounds can be useful.

Fat status of tissues.

I often found that when my diet was high in unsaturated fats my skin burnt extremely quickly. It’s been noted that people who often use sunblock often burn much quicker when in the sun without sunscreen. Increased consumption of unsaturated fatty acids appear to be linked to an increase in melanoma (Bourne, Mackie, & Curtin, 1987). Anecdotally I found that with a large decrease in PUFA my skin tolerates much longer bouts of sunshine before burning (not bad for a semi ginger pasty bloke from Kent!) , even in the intense middle-eastern heat. High fat diets, whether un/saturated also decrease mitochondrial activity and lower oxidative metabolism (Titov et al., 2016). It’s well known that vegetable oil consumption is linked to cancer (Niknamian, S., Kalamian, 2016) and heated vegetable oils that enter the body are already oxidised causing additional inflammation.

Perhaps melanoma is substantially increased when an individual has increased estrogen exposure, excessive amounts of unsaturated fatty acids in the skin and vitamin A deficiency but does that still implicate sunlight as the cause of skin cancer? The A to B scenario hopefully seems less convincing.

Modulating estrogen and decreasing PUFA in the skin is a step in the right direction. Increasing skin tolerance for longer days in the sun will be beneficial for many people. Using a homemade sun screen with minimal PUFA in can be useful for those wanting to spend extra time in the sun without damaging the skin and of course depending on the latitude, avoiding peak sun times is prudent to avoid excess UV light.

More information on resolving these issues can be found in the member’s area.

Being holistic versus (holistic) critical thinking.

sunrise-2.png

Is being 'holistic' an advantage to holistic critical thinking? It’s relatively easy to get drawn into a naturalistic fallacy of consuming all foods in their most raw natural state. Perhaps you’re someone who went from a fast food diet, where you didn’t feel your best, to consuming more whole foods, fresh fruit and vegetables? It’s easy to see how a switch and positive changes can occur in the short term. The next step is to start preaching to the masses how sugar is bad, how your life will be saved with green smoothies, nuts, seeds and coffee butt cleanses. For the record this is a waste of coffee and not to far from what I was preaching a decade ago. So what does it mean to be holistic?There’s a large movement within the health fitness and wellness industry (and lay people) that are drawn to  'holistic' thinking, and their definition is often enforced by the fallacy that everything in its most natural state is better for human health. This appears to include foods like nut milks (yes you can milk a nut), kale smoothies, seed oils like flax and undercooked broccoli and other greens, despite their negative effects on human health when consumed in substantial amounts. It’s a religion, and much like religion and with this mind-set it isn’t going to make you any healthier. I’ll make reference here to the late, great Beastie Boy, MCA who despite being a vegan and a Buddhist died far too early from throat cancer.

It is true that eating plenty of foods in their most natural state f(or some foods) can be important for health. But the image on the right highlights the faulty narrative of being holistic without thinking about the consequences. Fruits, vegetables, dairy products, meats and the like require minimal processing but in the quest for longevity, taste and profit, adding preservatives and flavour enhancers causes our food sources to become problematic. The so called ‘holistic’ folk get lost in this narrative urging your diet to become abundant in the rawest, greenest and brownest foods, that are most indigestible and contain potent inhibitors of biological function.

To integrate a level of holism into nutrition and function requires a level of critical thinking. What do these foods contain? How do they affect physiology? It’s well known that the brassica vegetables like broccoli, cauliflower and sprouts contain potent compounds that decrease energy output. These goitregens inhibit thyroid output and isothiocyanates found in cruciferous vegetables affects TPO or thyroid peroxidase, both of which are exacerbated when iodine uptake or restriction is present. Research tends to support these problematic effects (Choi & Kim, 2014)(Truong, Baron-Dubourdieu, Rougier, & Guénel, 2010), but much attention is focused on the smaller compounds that seem to work well in test tubes, rather than its global effects. As the environment becomes more stressful for biology do we need more building or reducing factors within our control?

The environment can be a harsh place. There are plenty of pollutants that have a negative effect on fertility, metabolism and other key endocrine aspects of health, some of which are industrial, others purposively added to food (arguably another form of industry) (Rajpert-De Meyts, Skakkebaek, & Toppari, 2000)(Upson, Harmon, & Baird, 2016). We can argue that the environment has always been a harsh place and adaptation has taken place as a response to selective pressures at the heart of evolution. Yet currently we are heading towards a tipping point, as environmental stimulants appear to be at the heart of acquired biological damage that is inherited by offspring. Cancer, fertility and other metabolic diseases are more common than ever and yet the approach is to keep seeking the magic bullet to ameliorate the fate that awaits many of us.

If we were to ask:

What enhances biological function, makes us more robust and allows us to have a stronger conversation with a stressful environment?

Rather than succumb to its stressors.

The highway to health

The highway to health

A biological system in its best working order could be represented, as an infinite road stretching into the  distance, perhaps with the odd bump along the way or a slight deviation but an ability to get back on track is available. Compare that to the inhibitory T-junction where the body cannot function as the clear straight road, it deviates from its true organised direction. The journey is laboured and restrictive. The ability to flux and respond to stressors is key and adequate energy is an essential component of reorganisation.

Nutrition is an important factor for such conversations with the environment. Eating a diet that is dominated with foods that are difficult to digest, decrease energy availability and create more stress are not going to make chatting any easier. If we make the effort to understand what keeps a cell and its mitochondria functioning at its most efficient state, we can understand why aspects such as sugar, adequate protein, moderate exercise, light and other factors, can play a role in overcoming current stimulus that decrease function and increase disease states.

The following article is definitely worth a read for an understanding of the concepts that I have talked about. http://raypeat.com/articles/articles/vegetables.shtm

Methylene Blue - Let’s play the blues.

Methylene blue - an overview: There’s been many times when I have recommended compounds/agents to create change in clients. Even the basic strategies of increasing sugar, not wearing sunscreen or the use of aspirin for improving energy and decreasing oxidative stress has moved the odd eyebrow to be raised. Objections often dissipate when presented with the line of reasoning and research that supports my recommendations. Effective clients will often do their own research and come back armed with significant questions for a better understanding of what is trying to be achieved. Research previously conducted by the Nobel scientist Albert Szent Györgi showed that previously damaged cells that produce efficient energy can be restored with methylene blue.

So with the tradition of raising more eyebrows let’s suggest the use of a blue dye that can be added to aquariums for improving marine life health. That’s right you put it in fish tanks. Why indeed would you not think of consuming glassfuls of the stuff?

Methylene blue (MB) is a dye that has shown promising results in the following areas:

  • Tissue hypoxia
  • Hyper dynamic circulation of the liver post cirrhosis
  • Improved low blood pressure states
  • Hepato-pulmonary syndrome
  • Anti malarial agent
  • Improves mitochondrial function
  • Detects parasites such as h-Pylori
  • With additional treatment of red light has anti-parasitic effects.
  • Anti-microbial-kills MRSA
  • Hepatitis C and other conditions also effectively treated in tandem with red light application.
  • Anti-Alzheimer’s agent- attenuates amyloid plaques and improves mitochondrial function.

MB is able to decrease both nitric oxide and guanylate cyclase, both exert their influence on smooth cells and tissue, explaining its role in reversing severely low blood pressure states ( Medically termed - catecholamine refractory vasoplegia)

If we look closely at a couple of the major mechanisms, we can see that from a metabolic standpoint MB has some interesting benefits. It decreases hypoxia or increases oxygen saturation within the body, whilst also improving mitochondrial energy production.

The respiratory/ electron transfer (ETC) chain, that is essentially the mechanism providing optimal use of oxygen, carbohydrate, fat, when this functions well, carbon dioxide is produced, which allows for optimal dissociation of oxygen from haemoglobin. When the respiratory chain is damaged, cells often have to switch to inefficient anaerobic sources of energy production, wasting sugar and increasing lactic acid, which continue to decrease aspects of cellular function.

Methemoglobinemia is a state where haemoglobin is unable to carry oxygen. MB reacts within the red blood cell and converts ferric ions, which have been oxidised, to its former oxygen carrying state. Additionally it helps to repair the ETC that is often damaged due to pollutant, poison or inefficient metabolic induced changes as seen in states of Alzheimer’s (Oz, Lorke, & Petroianu, 2009).

Another novel aspect of MB is the treatment of parasitic infection. MB absorbs and reacts with the spectrum of red light acting as an antimicrobial/parasitic agent.

“ Protozoa require the invasion of a suitable host to complete all or part of their life cycle.”

So what constitutes an appropriate host? I offer the following definition.

An individual or organism that is unable to assimilate and produce energy effectively, organise optimal cellular function and provide an immune response capable of expelling or eradicating an opportunistic parasitic/bacterial infection.

I quote Ray Peat with the following:

“ Occasionally you have very vigorous parasites that have intentions. If they encounter you in a state when your blood sugar is low, for example, the parasites might find an opportunity and start disorganising your system. So the competing systems’ lower system getting a foothold in a higher system, counts as randomness. The assumption of randomness is usually that everything is always random. What has been ordered is achieved at a high cost, the arrow of time for these people is that you have to expend energy to create order, and get things piled up in a certain way can only do that by expending energy somewhere else. "

MB and the use low level laser therapy (or LLLT which uses red or near infra red light) have a commonality with their ability to reduce the inhibitory actions of nitric oxide. This leads to enhanced cytochrome c oxidase action at complex IV of the ETC ( in English this means the enzyme that promotes better function of the cells that use oxygen efficiently), promoting increased cellular respiration and energy production (ATP). These dual actions appear to be an effective anti-parasitic treatment.

If your still running around taking a rucksack full of supplements, restricting energy and immune enhancing foods to kill parasites and candida, this may be a far more effective therapy to consider. It should be no surprise that that considering these actions, the use of MB is being investigated as a serious therapy in the fight against cancer. The biology of cancer can be attributed to metabolic defects/damage within the mitochondria leading to mutations.

Of course like any compound whether it be oxygen, water, broccoli or vodka certain doses are problematic. However these are generally high. For example doses used to treat malaria are suggested as 36-72mg/kg over 3 days (Meissner et al., 2006) and safe therapeutic doses are suggested as <2mg/kg (Ginimuge & Jyothi, 2010). Newborn babies seem susceptible to MB side effects such as skin discoloration, respiratory distress and other unwanted symptoms. However, the mechanisms of why this might happen, requires a blog alone. It also appears problematic to those taking SSRI’s and can increase serotonin uptake to toxic levels.

What I have learnt from taking MB.

I found that if I took doses of more than 5mg total within a day or two of each other, my urine turned blue. A self -limiting factor that probably suggests that I was taking too much. I also had the odd crazy dream. I generally found that a total intake of 2.5 mgs or around 5 drops 2-3 days per week seemed to serve me well. I titrated up and found the optimal dose, something which I strongly recommend doing for all.

I found that my pulse oximeter readings improved from a general SpO2 93-97 to regular 98. Which is interesting as one side effect previously suggested is the ability of MB to underestimate pulse ox readings. It’s prudent to imply that any therapeutic dose may only create change as the system allows. Therefore basics strategies such as effective blood sugar regulation, through regular eating and other strategies should be applied.

Ps it’s also great at reversing cyanide and nitrate poisoning in fish. Might it be useful in humans consuming too much bacon?

Estrogen and aromatase - Keeping the wolves from the door.

Estrogen and aromatase,  (and the  role of prolactin and a lack of progesterone) in cancer are well documented and so are the stimulatory effects of the neuro-endocrine (nervous system/hormones) disruptors termed xenoestrogens, which mimic the action and excess of estrogen (Kim, Kurita, & Bulun, 2013) (Mungenast & Thalhammer, 2014). Estrogen and notably estradiol/E2 is often measured by a standard blood test, which remains as problematic as other blood tests such as TSH, which I have previously described. “ At first, it was assumed that the amount of the hormone in the blood corresponded to the effectiveness of that hormone. Whatever was in the blood was being delivered to the “target tissues.” But as the idea of measuring “protein bound iodine” (PBI) to determine thyroid function came into disrepute (because it never had a scientific basis at all), new ideas of measuring “active hormones” came into the marketplace, and currently the doctrine is that the “bound” hormones are inactive, and the active hormones are “free.” Ray Peat

In addition to the obvious production of estrogen in the reproductive tissues, it’s possible to increase estrogen conversion via aromatase, an enzyme which converts androgens such as testosterone to estrogen, is one of the other main factors. Adipose tissue is a prime location for increased aromatase activity.

Another problem with measuring hormones in the blood is that it rarely accounts for the intracellular accumulation of hormones. Estrogen in excess in the cell, promotes fluid retention, swelling and causes an increase in calcium. Measuring pituitary hormones and in particular prolactin (PRL) may give us a better indication of the relative excess of estrogen due to estrogens stimulatory effect on the anterior pituitary and PRL.

PRL excess is associated with issues such as breast cancer, prostate cancer, resistance to chemotherapy, infertility in both men and women, male reproductive health and galactorrhea (Sethi, Chanukya, & Nagesh, 2012) (Rousseau, Cossette, Grenier, & Martinoli, 2002). Treating PRL excess, particularly linked to the most common form of pituitary tumour (1:1000), the prolactinoma is often treated effectively by the dopamine agonists Bromocriptine or Cabergoline. However, it’s not beyond the realms of possibility that prevention and treatment of excess PRL production, be achieved with decreasing synthesis and exposure to estrogens both endogenous and from external sources.

Myopic thinking.

Modern medical thinking and analysis has led us to a reduced proposition when it comes to diseases like cancer. Cancer is essentially a metabolic disease, and the proposed respiratory defect, the idea of scientist Otto Warburg, is often replaced by the mechanistic thinking of the receptor theory of disease. Estrogen receptors are one of the main evaluations for assessing types of cancer but the very essence of the testing leads us to an increased myopic line of questioning, failing to ask the necessary questions that underlie a persons health status.

If a city is being evacuated, its railroad transportation system, will be quickly “saturated,” and the impatience of a million people waiting for a ride wont make much difference. But if they decide to leave on foot, by bicycle, boat or balloon, in all directions, they can leave as soon as they want to, any number of people can leave at approximately the same time. A non-specific system is ‘saturable,” a nonspecific system isn’t saturable. The idea of a cellular “receptor” is essentially that of a “specific” transport and/or response system. Specific transporters or receptors have been proposed for almost everything in biology - for very interesting ideological reasons-- and the result has been that the nonspecific processes are ignored and supressed. Ray Peat

Solutions.

Sometimes there are minimal opportunities for people to change their environment. Perhaps creating more solutions to enable better conversations with the environment, is the most pragmatic solution available?

Maintaining the body’s production of energy by optimising thyroid production, suppression of TSH (thyroid stimulating hormone) and lowering of other stress hormones like ACTH, intake of carbohydrates, protein and adequate light can support the necessary energy needed for the liver and digestive system to enhance detoxification of estrogen and estrogen mimickers.  A sluggish, fatty or hypothyroid state of the liver, makes it difficult for estrogen to be excreted. In states of constipation, beta glucaronidase converts inactive estrogen to the active form.  Keeping both estrogen and aromatase low seems a step in the right direction.

Foods also have the capacity to enhance estrogen synthesis. Mushrooms have shown to be a potent inhibitor of aromatase enzymes and have the capacity to lower the systemic production of estrogen (Grube, Eng, Kao, Kwon, & Chen, 2001). However it’s important to note that mushrooms need substantial cooking to reduce the liver toxins present.

“The hydrazine-containing toxins that Toth and others wrote about are destroyed by heat. Since extracts made by boiling the mushrooms for three hours were very active, I think it's good to boil them from one to three hours.

If you want to know more about prepping mushrooms and soups, then check out the link below for The Nutrition Coach, who reminded me why mushrooms for lowering estrogen and a great source of protein will be helpful when consumed regularly.

Gestational diabetes and metformin-Is that the best that medical thinking has to offer?

Gestational diabetes or elevated blood sugar is often treated with metformin to improve blood sugar levels and considered the standard approach to treating gestational diabetes. The research suggests that it has little negative effects on the pregnant mother. However, does significant risks to both mother and baby if the incidence of premature birth count? Here are a few aspects to consider regarding the use of metformin to control blood sugar during pregnancy. A study of patients receiving a dose of metformin, combination of Clomiphene citrate (CC) and metformin both faired better than CC alone for the induction of ovulation (Neveu, Granger, St-Michel, & Lavoie, 2007).  As the combined group showed no benefit compared to metformin alone, one might consider that metformin alone may be considered for the positive effects.

In another study metformin and diet interventions showed a significant outcome compared to non-metformin-diet interventions. The metformin diet showed a reduction of 14 adverse events in a group of 76 expectant mothers, compared to the non-treated group of 36 adverse events out of 76 pregnancies (Glueck et al., 2013).

Thatcher and Jackson (Thatcher & Jackson, 2006) compared pregnancies of 188 women. 61 experienced miscarriages and 11 of those had stopped taking metformin, suggesting other abnormalities beyond metformin’s actions. 81% of women with pregnancies before metformin, 67% had prior miscarriages. 37% of these also miscarried again. Whilst metformin appeared to show minimal effects to mother and foetus 22% were born prematurely.

Whilst metformin has shown favourable outcomes in PCOS states, questions around pertinent biological mechanisms should warrant further discussion. It’s well known that two key endocrine actions may be compromised during the failure to achieve full gestation. Estrogen induces hypoxia in the uterus (Peat, 1997) and failure to produce adequate progesterone to counter the effects of estrogen may be implicated in the commonly fragile time around weeks 9-10 of pregnancy and incidence of miscarriage.

A concern of metformin are its affect transplacentally. Metformin appears to influence testicular size in males and affects sertoli cells. In females it may also lead to decreased androgen synthesis. Birth weight percentile is also significantly lower in pregnancies treated with metformin (Bertoldo, Faure, Dupont, & Froment, 2014)I Metformin has generally appeared safe in expecting mothers but considerable concern should be made regarding its long term effects to offspring and development most notably to reproductive tissues.

Hypothyroidism is a key factor in maintenance of pregnancy and alongside progesterone, thyroid hormone deficiency can be implicated in poor cellular energetics, production of adenosine triphosphate (ATP) and blood sugar regulation. There remains much debate about the issue of subclinical hypothyroidism, values and when to treat and perhaps metformin’s role despite showing some promises may be treating a symptom related to insulin sensitivity.

So perhaps these questions might be more pertinent before prescribing an agent that shows potentially negative effects to the fetus?

  1. What is the nutrition of the mother, is it enough and does it contain enough nutrients to enhance/maintain adequate progesterone/thyroid production?
  2. Is estrogen increasing at a rate that suppresses progesterone/thyroid levels and persistently decreases insulin sensitivity?
  3. Is there enough carbohydrate in the diet to ensure that carbohydrate is effectively utilised instead of persistent conversion of fats, increasing overall stress to both mother and fetus?
  4. Are the values of hypothyroidism and the identification of subclinical/functional hypothyroid factors appropriate?
  5. Is gestational diabetes a reflection of the above points?

The use of metformin, without questioning these mechanisms, remains at best a reduced treatment that fails to address a range of biological interactions and function.

What is functional hypothyroidism?

You won’t find the term functional hypothyroidism in the medical literature, or at least not yet. Primarily due to clinical hypothyroidism being bound to a rigid assessment usually diagnosed by the blood test thyroid stimulating hormone or TSH. TSH secretion is controlled by synthesis of thyroid releasing hormone or TRH in the supraortic and supraventricular nuclei of the hypothalamus. TRH is transported to the anterior pituitary by the hypothalamo- hypophysial portal system where it stimulates synthesis of TSH. T4, T3 and TRH control the secretion of TSH (Gardner et al., 2011).

TSH production can also be affected by TSH receptor damage, medical drugs, disease states, iodide, blood glucose levels and other circulating hormones TSH may also be affected by environmental pollutants and heavy metals (Llop et al., 2015).  Metabolic disease and increases in Body Mass Index appear to be correlated with an increase in TSH levels (Ruhla et al., 2010).

Often, you will see clear links and studies to key micronutrients such as zinc, selenium, iodine and other important co-factors. These deficiencies can exist demographically but usually in westernised societies, there deficiency can be linked to impaired absorption rates, perhaps linked to digestive dysfunction and other factors.

“Measuring the amount of thyroid in the blood isn’t a good way to evaluate adequacy of thyroid function, since the response of tissues to the hormone can be suppressed (for example, by unsaturated fats) (Peat, R.1999).

 Dietary factors such as unsaturated fatty acids in the diet may potentially be one of the most overlooked factors that supress thyroid function. Other factors such as caloric restriction, stressful environments, over exercising and other factors are some of the others. It’s well known that in certain areas of hormone dysregulation such as menstrual cycle irregularities, oligoamenorrohea (loss of cycle), anovulation (failure to ovulate) and lack of libido and fertility in both men and women,  can be attributed to poor energy intake and environmental factors (Nieuwenhuijsen et al., 2014) (Skakkebæk, 2003). Dietary factors have synergy with hormonal imbalances perpetuating high levels of estrogen.

The functional suppression of thyroid function by unsaturated fats, eating a so-called healthy diet (full of uncooked brassica vegetables, nuts and seeds) orthorexic states and other factors is largely ignored by physicians.

I can say with some certainty, after completing postgraduate studies at university with a number of Doctors, that diet and inhibitory factors of diet rarely get assessed when it comes to assessing energy and thyroid function.

A persistent functional hypothyroid state, induced by unsaturated fats may lead to the pre-diabetic and diabetic states induced by an inability to utilise carbohydrate and the preferential shift to use of fats instead of sugars as suggested in the Randle or glucose fatty acid cycle (Randle, Garland, Hales, & Newsholme, 1963). Increased cortisol, oxidation, decreased carbon dioxide and an increased stress on the oxidative system, could potentially lead to glycolysis and an increase in lactic acid, further increasing damage, stress and further suppression of thyroid function.

Measurement of thyroid blood tests remains inaccurate and problematic without the inclusion of a variety of symptoms and previously accurate assessment, such as basal metabolic rate, body temperature and pulse. The suppression of both thyroid and adequate energy states will always remain.

As the common approach for diagnosing hypothyroidism is having TSH above 4 or 5 mmUL and the preferred treatment is to supplement with synthetic levothyroxine. How much change can you realistically achieve if you fail to address the supressed metabolism induced by diet, an individuals susceptibility to stress and their own environment?

An energetic approach to restoring gut function: Part 1.

Let’s kick this blog off with a question as to whether or not an energetic approach to restoring  gut function is useful or should we rely on testing and supplements? Let me clarify, that I have had my fair share of success stories with a reduced and diagnostic approach to improving gut health. Just like I have also had my fair share of kickbacks from the laboratory for recommending their tests. At one point I was using nearly 200 stool tests per year and making a little cash on the side. Many of the tests worked in isolating some specific disturbance to their gut bacteria, presence of a parasite or elevation of putrefied fatty acids. A ‘cleansing’ diet was promoted and a few supplements for good measure created some short term change whilst the client was in my care. But here’s why the long-term approach to that type of assessment and treatment may not be the best response. A standard functional medicine approach  after spending quite a lot of cash on an integrated stool test is using the 4 R approach.

Remove (offending parties)- spend money on supplements

Restore function- spend money on supplements

Re-inoculate - spend money on nice expensive probiotics

Repair gut lining- spend money on supplements

Regurgitate. Ok the 5th one is mine but no supplements needed.

By taking this approach, an important question is not asked of the individual. Why is this person experiencing an overgrowth of bacteria/SIBO, parasitic infection, endotoxin overgrowth, inflammation and degradation of the bowel lining? I like to think that it is not because of the easy kickbacks FM practitioners are getting for the lab tests and supplements they recommend? So what is the persons level of biological energy and immune system function that allows their digestive system to get in such a state. We know there are some usual suspects. Food, stress or alcohol perhaps?

The typical gastrointestinal complaints people came to me with, were bloating, excess gas, constipation or irritated loose stools combined with poor energy. It was Ilya Mechnikov who originally stated that death starts in the bowel or colon and there’s’ certainly many degenerative and inflammatory conditions that appear at the last stop to poopy central. But is the bowel the main driver of this dysfunction? Many of the symptoms that I recalled earlier are also key symptoms of an energetic and perhaps a thyroid dysfunction. So instead of reaching for our drastic 4 R protocol with an expensive poo test lets consider the following.

 The likes of Broda Barnes and Ray Peat have highlighted how a lack of energy, either from a low or inappropriate food intake or a dysfunctional hypothalamic-pituitary-adrenal-thyroid axis can be evaluated by assessing body temperature and the combination of pulse. Additional information on Thyroid and TSH evaluation can be found here.

Most people are aware that when they get stressed or exercise, blood is shunted away from the digestive system to the periphery and other working tissues. Even the concept of high Adreno-corticotrophic hormone (ACTH), cortico releasing hormone (CRH) and adrenal production of cortisol is becoming common place in work and gym environments alike. These hormones suppress thyroid hormone and the energy compound ATP that provide energy for tissues.

It’s also well known that low energy states create tight painful muscles that are difficult to relax and one might be able to apply that line of thought to the smooth muscle tissues that regulate bowel contractility. Therefore a low energy state that does not allow for adequate energy production will not allow adequate digestion and bowel function to occur. Cold hands and feet can be a symptom of not eating enough carbohydrate and protein.

If the cold hands and feet, low body temperature, fatigue, constipation don’t resolve from eating energy rich meals that contain plenty of fruit and contains little of the foods that promote the bowel irritants histamine and serotonin (nuts, seeds, vegetable oils, grains, gluten free products, beans and pulses). Then, often factors that influence the hormones such as thyroid, estrogen and progesterone may need a deeper consideration.

I drafted a little flow chart that will be helpful for some quick strategies on what might be happening but what I would like to focus on the low energy state that might have its source from a food or hormone factor or perhaps both. Instead of using a strategy like the 4 R approach, these simple questions can help guide you to understanding whether it is the foods that you eat or an energetic factor that could be causing your digestive system to suffer. It's not a complete algorithm but it does offer some simple solutions that have helped plenty of people resolve digestion and energy issues.

Foot note: I haven't needed a stool test with a client for over 4 years now following this chart.

 

In part 2 I will elaborate on foods and basic supplements that can be used to resolve most long standing digestive issues and understanding other hormone actions that create digestive discord.

Osteoporosis- could your exercise, nutrition and medical advice be better?

Osteoporosis and bone health, like many other aspects of optimal biology is a product of an organisms inputs and reactions to environmental stimulus. Osteoporosis is a condition like others, where prevention is often easier than the cure but perhaps the cure has been overcomplicated? Osteoporosis is a multifactorial musculoskeletal disease that is usually associated with the ageing process, decreased bone mineral density (BMD) and its tendency to fracture easily.       It’s clear that a number of factors that can be maintained throughout life to reduce the incidence of Osteoporosis in both men and women. Before we review those and compare with current guidelines, here’s some background info on the subject.

Primary Osteoporosis is the age related decline in men at around 70 and suggested as being a postmenopausal state, induced through the decreased production of estrogen in females. This last point is accepted in medical literature as the main cause of osteoporosis in females but may be severely flawed (more on this point later).

Secondary osteoporosis can be related to the following factors

Hypogonadism - testosterone/estrogen deficiency
Endocrine disease - Cushing’s syndrome, acromegaly, thyrotoxicosis, Addison’s disease and hyperparathyroidism
Dietary or assimilation deficiencies of calcium, vitamin K, vitamin D and other nutrients
Inflammation-rheumatoid arthritis, systemic lupus and ankylosing spondylitis
Neoplasms- Myleoma, lymphoma and leukaemia
Reduced physical activity
Medical drugs - corticosteroids, antiretroviral, antipsychotic, chemotherapy, hormone therapy, nicotine and excessive alcohol
Family history/genetics
Diabetes

The financial burden from osteoporosis generally, will increase from 98 Million Euros to 121 billion with proportional increases of 27.5 million to approximately 34 million people between the years 2010 to 2025 (Hernlund et al., 2013). Despite these huge burdens there appears to be a lack of well-designed educational programs that are geared at prevention of osteoporosis through non-pharmacological means.

The supplementation of vitamin D and calcium are well documented in osteoporosis strategies but a strategy to avoid these states are diets containing adequate calcium, vitamin A, K, magnesium (and others) adequate sunlight and moderate exercise.

Ok, so there’s a problem, it’s big business and there’s a lot of great info on how to avoid it right? Well no and here are the major points why I believe its not.

Diagnosis

 Dual energy X-ray absorptiometry (DEXA) is the recommended choice for osteoporosis diagnosis, serum calcium, phosphate, creatinine (with GFR) alkaline phosphatase, liver function, 25 OHD, total testosterone, estrogen CBC and 24 urinary calcium excretion are recommended for the interpretation of secondary causes of osteoporosis (Watts et al., 2012).

Hormones

Estrogen loss is touted as the most significant factor in decreasing BMD yet it’s action only retards resorption, or the removal of calcium from bone. Estrogen tends to inhibit the action of osteoclasts which ultimately reduce BMD. It’s the main reason the introduction of hormone replacement therapy (HRT) was considered as the primary treatment until its long-term use was found to induce clotting and cancer in women. So estrogen does not reverse Osteoporosis, it prevents further bone loss.

A variety of studies have suggested little influence of testosterone in males on BMD and that low estradiol levels combined with elevated sex hormone binding globulin appear to increase the loss of BMD (Cauley et al., 2010). A point worth noting from the correlation associated with higher estradiol levels and decreased BMD loss is that all participants in the study were recorded as having increased weight and BMD, which may influence skeletal modelling due to increased bone-loading parameters. Perhaps too much emphasis has been given to the suggestion that estrogen and its primary role of tissue proliferation amongst others, which should follow the course of age related decline?

Progesterone on the other hand has been shown to be a bone trophic or building factor that increases mineralisation of BMD, via osteoblasts (Prior, 1990). Stress increases cortisol and decreases progesterone binding at the receptor, with a preference for the glucocorticoid. Ray Peat (1997) points out that cortisol causes bone loss and its widely accepted that progesterone has an “antiglucocorticoid” action, it is reasonable to think that progesterone should protect against bone loss, and that it is a progesterone deficiency after menopause which is a major factor in the development of osteoporosis.

Thyrotoxicosis has been suggested as a mechanism of bone resorption but this appears inaccurate-  Ray Peat does a much better job at explaining this.

Medical treatment

Bisphosphonates are the first line medical treatment for treating osteoporosis and show modest changes to hip and vertebral BMD over 3 years. There use may come at a risk. Gastro intestinal side effects are well documented and in some the increase of osteonecrosis of the jaw has been observed. In some, the long-term use has been shown not only to increase the rate of fragility fracture but also to inhibit the healing process. It should be noted that adequate calcium and vitamin D in the diet are essential for bisphosphonate effectiveness

 Nutrition

 There tend to be two well-known stances to the fitness industries approach to nutrition. One, the transformation approach, where limiting of nutrients, particularly dairy and carbohydrates and intermittent fasting are the norm. Another, the holistic warrior whose consumption of chia seeds and all things green, raw and limiting of dairy and sugar again,  may be a factor into lowering BMD in later life. Calcium is an essential nutrient for bone health and dairy is indeed a great source of calcium. Here’s an old blog on the subject.

 It’s clear that adequate vitamin D is a nutrient that is important in BMD maintenance. It regulates calcium levels, decreases the production of parathyroid hormone, which is a potent resorption factor of skeletal calcium when calcium or vitamin D are low. Here are the main points that relate to diet.

  • Vitamin D in isolation and particularly high doses increases fracture rates (Janssen, Samson, & Verhaar, 2002)
  • Unless vitamin D is accompanied by adequate calcium, BMD can decrease further.
  • Vitamin K2 can prevent the calcification of soft tissues and help improve blood calcium levels (Masterjohn, 2007)
  • High meat and diets high in pulses and beans can have a negative effect on calcium levels due to their high phosphate levels.
  • Unless you assess other key nutrients like magnesium and the factors discussed above
  • Low diary intake can be associated with poor bone health.
  • The low carbohydrate, raw green and seed eating diet suggested by holistic health practitioners may contribute to lower BMD.

Exercise

Regular exercise has been touted as a significant factor in maintaining muscle mass and increasing BMD. But is the type of exercise that people are doing, increasingly in their younger years, contributing to better or worse outcomes to BMD. For bone to form adequate carbon dioxide (CO2 ) is essential. Some exercise regimes are so challenging, they contribute to excess levels of metabolic acidosis (lactic acid) and passing of CO2 from the body (worth noting that sugar consumption can also help to increase CO2 production) . Perhaps for exercise to be effective it should be light to moderate, with adequate rest periods that don’t mean that the participant is lying in a pool their sweat and vomit.

Walking, strength training with adequate rest, yoga, Pilates and other modes of moderate exercise appear most suitable for modest improvements to bone health but the diet and hormone factors are key.

It’s clear that osteoporosis is in the rise but it can be reversed. But instead of heading advice like cutting out dairy, eating lots of uncooked vegetables and training to complete exhaustion. There are more suitable mechanisms for improving bone health
