Autoimmunity part 2: The autoimmune paleo diet - The Pro's and Cons

Where's the ice cream?!.jpg

 In this post I’m going to explore the mechanisms of the recommended autoimmune paleo diet (AIPD)  and suggest why it has very useful short term applications which are a mixed bag of interventions, reductionisms and shouldn’t be considered as a long term solution.

 In the last autoimmunity post you might remember how scientists like Polly Matzinger give an insight of auto immune disease that’s often not given enough credit. In summary of the danger theory, which is the body recognising self and the potentially damaged self. These damaged tissues be they thyroid or another tissue, is marked for removal from the system to prevent more damage occurring. The body is a pretty impressive organism that should be credited with being able to recognise its own tissues and respond with an effective response to restore best working order. So why should we discount this theory?  It’s essential to remember that a significant driver of autoimmunity is the increased prevalence of the disease in females (some 10 x more than males)  is driven by estrogen, estrogen like compounds and their ubiquity in the environment. Recently I’ve seen more people in the preceding months with vitiligo than I have seen in my entire lifetime but then I do live in a very polluted city.

 The recommendations for the autoimmune paleo diet protocol has some positives but the thought process behind such a diet has shortcomings and it’s important to tease out why it can be successful for some. I’ve always found the idea that a paleo lithic diet be entertained for health somewhat problematic. Archaeological specimens of older adults are generally lacking, suggesting mortality ranges commonly found between 20-40 year old samples (Trinkaus, 2011). That’s not to say that there weren’t older adults, ,but to base the efficacy of a diet strategy on a previous era without any data is problematic.

 There are several reasons why the AIPD might have some positive outcomes.

1.     It removes many offending compounds that are known to irritate the digestive tract. Sweeteners,  emulsifiers and thickeners are well documented to increase intestinal inflammation. Gums like guar, locust bean and Irish sea moss (carrageenan) can cause substantial damage over time and is also implicated in blood sugar regulation and diabetes. http://diabetes.diabetesjournals.org/content/67/Supplement_1/770-P?fbclid=IwAR1W8LRbx1fSu02Tr3b19ANtu2qpkZRhnwySvCj8uUC4TpRhvzypNH6lERg

2.     Alcohol is restricted. It should come as no surprise that alcohol has the capacity to affect multiple aspects of function. Most forms of alcohol contain phytoestrogens and just like long term soy consumption has the capacity to influence the body as a source of external estrogens . Additionally, many other additives like yeasts, colorants and preservative like sulphites appear equally problematic. Drinking alcohol in moderation isn’t necessarily problematic but the more susceptible that one is to estrogen issues, alcohol will often be problematic. I have seen many old ladies in their 90’s have been prone to a tipple of sherry or whiskey.

3.     Nuts, seeds and oils which are high in unstable unsaturated fatty acids are also restricted ,decreasing lipid/fat oxidation and improve mitochondrial function. The restriction of grains can also be useful for a similar reasoning and grains like millet, sorghum and barley are known to slow metabolism, but the action of seeds and grains can promote increased intestinal serotonin and histamine production, increasing the burden and damage to digestive function. Both poly and monounsaturated fats appear to promote compromised liver function, degrade metabolism and contribute to obesity.

4.     Nightshades, legumes, egg whites and gluten are well known for their role in irritability of the digestive system.

When all is said and done, there’s every reason why many people should feel better when removing these usual suspects. But there are problems with the AIPD and I have seen individuals who despite following this protocol still present with both digestive and energy issues, primarily because deficits in energy still arise and potential autoimmune reactions persist. Given some of the problems associated with determining cause and effect of specific interventions. It would be easy to speculate why someone who was prone to eating lots of fast food, high in unstable oils, high fructose corn syrups, preservatives, binding agents and suffering autoimmune, digestive, energy and other hormone disturbances might respond well to this in the short term?

 

There’s another plus to the AIPD - it includes fruit but there’s a caveat that natural sugars which include fructose should be kept to a minimum. There’s also an emphasis on eating fruits that are high in intestinal irritating seeds like berries. Carbohydrate is essential for optimal energy production. It promotes adequate carbon dioxide production and allows more efficient energy production and oxygenation of tissues that you just don’t get with sustained fat oxidation. Even refined table sugar shouldn’t be frowned upon and would only be problematic if your diet contained large amounts of refined sugar and devoid of other key nutrients like fats, proteins, and lack of potassium or magnesium as an example.

 

So is the AIPD useful? Yes, but it’s extremely limited. So how about a strategy that allows function to improve systemically rather than in isolation? Studies are limited on the effectiveness of AIPD. Whilst not autoimmune as such, a study that utilised the AIPD in patients with IBD (irritable bowel disease) completed remission in 11/15patients or 73% (Konijeti et al., 2017). That’s great, but it shouldn’t be surprising, if you’re removing all the intestinal irritants and this reasoning should extend to some improvements in autoimmune patients, resolving digestive function should follow. Gut function improved but markers of inflammation such as CRP did not, and one participant withdrew due to irritation from raw food consumption.

 

Aspects of the autoimmune and or autointoxication theory of disease is derived from Elie Metchnikoff’s work on immunology, bacteria and gut function (Metchnikoff & Metchnikoff, 1908). Metchnikoff proposed that death and disease started in the colon. Whilst there’s little doubt  that optimising gut function has many beneficial effects, problems arise beyond the digestive tract that might occur in otherwise healthy diets. The bowel can be a hospitable place for problematic bacteria when hydrochloric acid is low, and motility is slow induced by a low energy/thyroid state. Metchnikoff proposed that beneficial strains of bacteria can be useful to prevent unwanted maladies related to bowel function. However he was keen to point out that animals blessed with longevity often shared features of high metabolic rates and low levels of gut bacteria. This may explain why supplemental probiotic studies are not consistent in results and may simply act as a competing factor against more problematic bacteria (Goldenberg et al., 2015). The AIPD preference for more fermented goodies might be useful, but more is definitely not better. As food is poorly digested and bacterial metabolites increase so does endotoxin, intestinal hyperpermeability (leaky gut) and changes to biochemistry and hormones.

 I won’t discuss dairy produce here as it’s rarely the issue, the stressed digestive system has a problem with dairy products. I have seen countless clients return to eating dairy products like cheese, ice cream and  milks.

Eating ice cream & walking in the sunshine is an easy way to lower aspects of autoimmunity.jpg

It’s rarely the dairy that’s at fault, it’s usually the stressed digestive system that’s the real issue.

The AIPD, well there’s plenty that can be improved upon to create longer lasting function without the need for reductionist notions like the greener, the more natural, the better. Especially the problems that have been known for many decades that cruciferous/brassica vegetables high in isothiocyanates and glucosinolates, are well known to increase levels of cyanide in tissues and are anti-metabolic in nature disrupting thyroid function.

Siri what is broccoli?.jpg

Broccoli was not a palaeolithic food

Brassica vegetables may have very little place in resolving autoimmune diseases.

The most effective form of preventing autoimmunity might be to keep metabolism at its best working order rather than slowing it down. The fascination of broccoli in the modern diet is not without paradox.  Broccoli certainly wasn’t consumed in the palaeolithic era, although other cruciferous vegetables may have been (Buck, 1956). It’s elevation to farmed commodity and food stuff appeared to take place in Hellenic culture and more rapidly promoted to support the invading Roman army.

Promoting a diet that has easily digested nutrients, energy and facilitates available thyroid hormone, addressing internal and external sources of estrogen, without increasing stress responses may be the most pragmatic approach of any diet to decrease autoimmune responses. Eating plenty of fruit, sugars and honey combined with good quality proteins, moderate saturated fat and low in unsaturated fats, seeds might be the best autoimmune diet.

Another problematic aspect of the AIPD is the emphasis on Omega 3 fatty acids such as DHA to lower inflammation and this isn’t limited to poorly constructed diets but a common error in autoimmune and inflammatory protocols (Constantin et al., 2018). Many studies and review such as this invoke the antioxidant effect properties of omega 3s due to their ability to lower markers such as triglycerides, cholesterol and crease metabolism. Surprisingly when you decrease metabolic rate, you decrease metabolic function, therefore inflammatory and oxidative markers are reduced. Sustained omega 3 and other unsaturated fatty acids accumulate in the brain and liver and decrease aerobic metabolism through sustained lipid peroxidation, especially so when carbohydrate metabolism is lost.


‘ Calorific restriction and well established diet supplementation with omega 3 regulates total cholesterol, LDL-C and triglycerides.’ (Constantin et al, 2018).

 In essence this has as much benefit as taking medication to lower cholesterol. Of course eating less calories produces less inflammation and if calories are restricted below a certain threshold, this lowers metabolism, giving the impression of less oxidation. If you’re going to support the notion that taking omega 3s lowers inflammation and as many espouse, lowers cardiovascular risk, the net effect will be degraded cholesterol that’s prone to oxidation and left with an excess of fatty acids also prone to lipid peroxidation. If we’re going to help more people with a so called autoimmune disease, perhaps we need to be thinking a little more holistically? If estrogen is a main driver of a perceived autoimmune state then improving its excretion through adequate energy, liver function and robust biology should be the answer. There’s no doubt that improving digestive function is helpful but the current zeitgeist, promoting plenty of undercooked vegetables in their most natural state, high in metabolic inhibitors is restrictive to decreasing aspects of autoimmunity.

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 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 (PCOS) - inheritance, environment and stress.

Estrogen excess.png

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.

Scar tissue - is it an issue?

Is scar tissue really an issue? 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).

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

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.

Muscles, pain, hormones and other stuff.

As a therapist who works within the fields of pain, movement, energy and digestion I have seen my share of pain and muscle dysfunction in clients. As my exposure to these situations increase, I realise more than ever, that the muscles are very rarely the problem. Specific muscle dysfunction usually boils down to spindle cell

Thyroid pic

dysfunction and notably Nuclear Bag Fibres (NBF) and Nuclear chain Fibres (NCF). The primary roles of these structures are related to stretch and contraction of muscle function. There can be other factors involving neuro transmitters, involved in nocicpetion such as glutamate, utilised in the withdrawal reflex and often referred to as first pain, (also known as Neospinalthalamic tract located in the Anterolateral system or ALS) and lasting, less than a tenth of a second. Problems can arise when the following pain pathway, called second pain (or Paleospinalthalmic tract also part of the ALS) has problematic feedback with first pain, this is mediated by Bradykinin.

Further complexities arise with serotonin and other structures associated with pain such as the Amygdala and Peri Aqueductal Gray (PAG) that are beyond the scope of this short blog. However a common, over looked feature of pain, may arise with hypothyroidism .

Low thyroid function can be classified effectively with assessment of a basal temperature test and a reading of between 36.6 and 37 degrees. Most blood tests designed to measure thyroid hormones such as TSH, T3, T4 and others, often do not reflect accurate function of thyroid hormone. This is often due to feedback loops between cellular function and the Pituitary gland. Some of the regular hallmarks of hypothyroidism are poor energy, weight gain, poor sleep, hair thinning, digestive dysfunction (constipation and also alternating loose stools), cold hands and feet and pain. Here's an old blog on thyroid and adrenalin issues.

Another assessment of thyroid function is the Achilles return reflex. When stimulating the myotactic reflex a hammer hits the Achilles tendon stimulating, the dorsi flexors or calf muscles. The response should be a quick return of the foot to it’s resting position but with low thyroid the foot returns slowly. Low thyroid output equals low ATP (Adenosine Tri Phosphate – the energy used by the mitochondria/cells). This low energy state does not allow for optimal contraction and relaxation. This is where we can see specific issues with NCF and NBF’s within the muscle spindle cell.

Muscle tendons and associated ligaments provide a feedback loop via the Golgi Tendon Organs or GTO’s. There’s potential for pre-existing GTO dysfunction to drive muscle dysfunction and vice versa. As far back as the 1960s symptoms associated with muscle disorder from low thyroid were.

* Weakness

* Cramps pain and stiffness

* Hypertrophy

* Myotonoid features.

A well-documented feature of hypothyroidism is muscular hypertrophied calf muscles and despite their size may often test weak to stimulation.

Muscle pain, may indeed not be muscle related, it may be due to many factors, suggested above and these may even be related to hormones and neurotransmitters. Many people often deal with muscle aches and pains by constantly focusing on mobility work but these structures continually return to their pre mobility work status (although this could also be an underlying stability issue). In reality there can be many factors that create dysfunction such as crude touch, vibration, nociception, Golgi, Pacini-pressure related structures and many more. But even after seeing a skilled therapist, these still don’t appear to get better, then addressing the chemical aspects of pain and function might be the next sensible thing to do.
