Ubiquities and other chronic confounders

April 6, 2014

When looking at health and chronic disease, there is a never ending confusion. The most powerful yardstick is to find the root cause of a chronic disease. The root cause of most diseases has eluded science thus far, despite intensive research. Therefore we sit in hope, waiting for breakthroughs. Medical science often uses large population studies and powerful statistical methods, however even these methods often fail to produce results. One reason is that they cannot penetrate the smokescreen of common things- we “cannot see the forest for the trees”.

This reminds me of Geoffrey Rose’s classic paper on the limits of epidemiology. Sick Individuals and Sick Populations.  “If everyone smoked 20 cigarettes a day, then clinical, case-control and cohort studies alike would lead us to conclude that lung cancer was a genetic disease; and in one sense that would be true, since if everyone is exposed to the necessary agent, then the distribution of cases is wholly determined by individual susceptibility.”. The moral being that UBIQUITIES cannot be detected by clinical, case-control or cohort studies. This is very noticeable in hypertension research due to the effect of salt- in industrialised countries it is universal/ ubiquitous for people to consume excessive amounts of salt.

In our case of Paleolithic diet- we must realise that Neolithic diet is ubiquitous. Therefore researchers will NEVER identify that it is causative of most diseases, unless they compare to a Paleo eating cohort. Because almost everyone eats a Neolithic diet, this will continually confound researchers.

Just as Dr Rose said regarding a population where everyone smoked, medical research often indicates that certain diseases are genetic when in fact they are are related to the ubiquitous Neolithic diet. For example, suppose that a particular gene gives you absolutely no risk of disease if your folic acid intake is the Paleo intake of the last 2 million years, but puts you at increased risk of disease if you have a lower intake of folic acid, such as commonly found in many Neolithic diets. Some people would say that you have a genetic disease, but it is obvious that it is also a nutritional disease, as with the right intake of folic acid you  are well. This is a gene-nutrient interaction. In this case the gene is not defective, it really is not a genetic disease per se, it is a case where the gene is a risk factor for the illness, the defect is that it is a susceptibility gene. Unfortunately it is probably a similar situation with many alleged discoveries of genes that “cause this” or “cause that”. If a gene puts you at risk of disease if you eat junk food is that a disease or just karma?

The example of folic acid given above in fact refers to one of the most common “mutations” the C677T mutation of the gene which codes the MTHFR enzyme. The MTHFR enzyme is important in the metabolism of the vitamin folic acid. 20% of the population have 2 copies of the “mutation”, and around 1/2 of the population carry one copy (Hardy-Weinberg equilibrium). It is well researched that in populations with a high intake of folic acid, people with this “mutation” are perfectly healthy, but of they live in areas with low folic acid intake, they are at increased risk of diseases such as DVT, pulmonary embolism, stroke, heart attack, spina bifida, and other diseases which can relate to folic acid metabolism. If you carry a mutation of MTHFR, you are one of 50% of the population, or 2 copies, then you are one of 20% of the population.

There are a number of other ubiquities and we should also add to the list chronic infections, some of which are almost ubiquitous.
Lead poisoning- until the massive EPA lead campaign began in 1990, 88% of American children had lead exposure sufficient to be called lead poisoning (and most of the other 12% with levels which have also been proven to have harmful effects). Lead has profound effects on many tissues of the body, via various mechanisms, particularly involving its similarity to calcium and magnesium, such as the important enzyme protein kinase C, and vitamin D. Lead is a known risk factor for hypertension cancer and heart attack.

Trace mineral deficiency, such as iodine deficiency
Glutamate exposure
Salt intake
Cereal
Dietary acid load
Another important group is lifelong or prolonged infection, many of which are very common:

EBV CMV Toxo Herpesvirus family HS HVZ Chlamydia Mycobacterium-tb-avium.
Helicobacter infection
SIBO (small intestinal bacterial overgrowth)

EBV (Epstein-Barr Virus infection, commonly known as infectious mononucleosis or glandular fever) affects around 90% of people by age 30 in urbant populations, and it invades T-cell lymphocytes and remains in them forever, permanently affecting your immune system. Retinol (the animal form of vitamin A, found in cod liver oil, or any other liver or kidneys) knocks out EBV but not many people eat liver or kidneys etc.

CMV (Cytomegalovirus) is a close relative of EBV and is also knocked out by retinol.
Chlamydia is interesting. Around 8% of birds are infected, and have it for life. The more I test for it (pneumonia cases) the more I find.


Beans Means Not Paleo

February 20, 2014

Here in Australia, everyone loves Dr Oz too! Recently Dr Oz interviewed Chris Kresser who is suggesting that dairy, beans and legumes are part of a Paleo diet. This is not so. Chris has just launched his book Your Personal Paleo Code, and we wish him success. Chris is a licensed acupuncturist and has a podcast show Revolution Health Radio which I highly recommend as a very interesting show if you are a podcast fan.

Prof Loren Cordain has written a rebuttal on legumes which outlines all the technical issues why and you can read this here. Beans and Legumes: Are They Paleo? This is a great summary of all the problems with beans and legumes. I also noted his past post about potatoes in response to other enquiries regarding other authors. I have some further comments below.

Like me, you may not have any serious illness (such as coeliac disease) that makes a strict diet necessary. Most of us are eating an UHG diet, that’s my name for an Urban Hunter Gatherer diet. Which means a fantastic diet, but we might slip in the odd glass of wine, chocolate, ice cream or other indulgence. Most people would still call this a Paleo diet, being 80 or 90% Paleo by calories with 10 or 20% palaver (in comparison Joe Average has 25% of diet as Paleo and 75% non-Paleo foods).

Paleo diet is a science, and proud of it. The usual definitions of Paleo are those you will find from researchers like Prof Cordain and Prof Staffan Lindeberg, the two of whom virtually established our current understanding of Paleo. They and their protegees, research teams and students are the source of power behind the explosion in understanding which has taken the world by storm. The correct definitions of Paleo found are in books by Prof Cordain, Robb Wolf and Ray Audette (Neanderthin was the first book outlining the current understanding, after Ray was advised by Prof Cordain, and managed to cure his diabetes and rheumatoid arthritis).

The real Paleo diet does not include dairy, beans/legumes, grains or potatoes. Commentators often compromise and sometimes, and say they are “allowable cheats” and some even go so far as to say that some of these are somehow Paleo. They are not. I suppose people should say “they are not Paleo, but a little bit won’t hurt most of us” (but not those with autoimmune disease or other serious health issues that may be caused by food). As for me, well I just admit that wine and chocolate and cheese and ice cream are definitely not Paleo, but they are less than 10% of my calories, and I am weak at times, and slowly slowly I hope to reduce them.

At least everyone agrees that wheat is not Paleo. Some people say dairy is Paleo- it’s not- a Paleo diet plus dairy is a pastoralist diet, and look where that got Ghenghis Khan- 2/3 of the known world! As for a Paleo diet plus potatoes, well please don’t ask me, I think the humble spud deserves to be humble. And beans and legumes, well sacre bleu! it is just not on.

There are several paths to get to a Paleo diet. The anthropologist path is based on research on hunter gatherers, the archeologist path is based on research on ancient man, or Ray Audette’s test (if was naked with a rock and a stick and no fire, could I have eaten it?) and several others. But one which I discovered early on in my journey (from 1999) and think is very important is the antinutrient test. Antinutrients is the term nutritionists use to describe toxins in everyday foods, probably because toxins or poisons does not sound nice, but that is what they are in every sense of the word. And what amazing toxins they are, with the ability to do tricks that no other known toxins can do, such as turn the immune system crazy.

Real Paleo foods have the lowest level of antinutrients of any nutritious foods. This is why a Paleo diet is the only true “detoxification” diet, all other diets are full of toxins, including most alleged detox diets. This also is why all Paleo foods can be eaten raw- at least in theory, you don’t need to feel obliged to do so. For a long time people ate a lot of foods raw. 10,000 years ago we started to eat toxic beans and grains, when it was discovered that cooking them first makes it possible to survive, though not thrive. Times were tough in those days, surviving was cool, they didn’t need Charles Darwin to tell them that, but the price of short term survival is long term health problems.

The worst sources of antinutrients are beans/legumes, and potatoes. Generally I would say that the worst legume in the Western world is the soy bean, followed by the kidney bean, then all the other beans. Green string beans are 90% husk and 10% seed, and only the seed part is harmful. If you want to know just how harmful some legumes in poor countries can get, read about lathyrism on Wikipedia  and Google Images.

Beans/legumes and potatoes rival wheat for toxins. I regard beans as detestable. I can understand that people who have eaten lots of lentils might miss them. I used to like them myself. Once I went Paleo, I quickly found that I became very sensitive to an upset stomach and general tiredness after eating beans and lentils, so I am glad to stay off them. As for potatoes, my patients with gastroenteritis bugs seem to often link a recurrence to taking some potatoes, and I hope somebody researches that one day.

If you want to eat beans or legumes as part of your diet, that’s your right, but rest assured that it is not a Paleo diet. And they certainly do not pass the antinutrient test.

Chris Kresser has posted a rebuttal to Prof Cordain click here.


Autoimmune disease treatment with the Paleo Diet

February 17, 2014

Autoimmune disease means a disease that is caused by a the immune system behaving wrongly and attacking the body. The proper role of the immune system is to attack viruses and bacterial disease etc.. When the immune system turns on us it is abnormal and this is the cause of many diseases such as rheumatoid arthritis, multiple sclerosis and hypothyroidism. “Officially” the root cause of most autoimmune disease is not known (like most diseases), however there is a large body of scientific literature which indicates that diet can play a critical role in the cause of these diseases.

This has been recognised for many years, as fasting and elemental diets (very purified diets mainly used in research) sometimes cause reductions in many autoimmune diseases. It is now strongly proven in some cases, as people with Coeliac disease are completely better if they are on a gluten free diet, and people with Crohn’s disease or Ulcerative Colitis can often be cured if they are on yeast free diet (particularly if their blood tests showed positive ASCA yeast antibodies). Please note that traditional hunter gatherer diets do not contain the wholesale amounts of yeast found in standard western diets, they only contain the odd small amount of yeast on the outside of certain fruits, like grapes.

Autoimmune disease is very common in modern man, yet very rare in hunter gatherers (whose diet is the basis of the Paleo diet). Research indicates this might be due to differences in diet and lifestyle. Researchers have pinned down many factors in food which affect immunity, and it appears the Paleo diet is low in factors that cause autoimmune disease.

Around 80% of the immune system resides in the gut in order to protect us against infections from our food and water, which until recent years was a major health problem in all countries, and still is a major problem in most of the world. The spleen is the largest immune organ in the body and blood from the spleen is mixed with blood from the gut which then travels to the liver for processing, so the immune system is intimately mingled with everything we eat.

It is also now apparent that immune system is programmed in the gut by a range of factors working together:
- genetic background
- diet (many different effects from diet)
- the presence of bacteria in the small intestine (SIBO= small intestinal bacterial overgrowth)
- the type of bacteria in the large intestine
- whether your gut leaks and how much (leaky gut- particularly small intestine and also large intestine)
- medications
- toxins
- vitamin D status and omega 3 status
- chronic infections such as glandular fever (Epstein-Barr Virus EBV) which permanently infect the T-cells that control the immune system.
- EVERYTHING that affects the gut or diet has implications for the immune system.

So when your immune system malfunctions, there is reason to believe that the malfunction has occurred in your gut, and attention to the above factors may help improve the immune system. Paleo diet addresses several of the factors- dietary proteins, the types of bacteria, SIBO and leaky gut can all be improved.

The Paleo diet has very little in the way of factors that upset the immune system. Whereas modern foods (the Neolithic diet) such as dairy and grains, beans, and potatoes do upset the immune system very directly. Neolithic foods contains toxins such as lectins which can make immune cells malfunction in bizarre ways. It also contains many proteins that were never present during the long evolution of our immune system.

SIBO means small intestinal bacterial overgrowth. The small intestine is supposed to have little or no bacteria, but it has been found that many people have quite a lot of bacteria. This can contribute to autoimmune and other disease. Neolithic food toxins such as lectins and protease inhibitors increase SIBO. The large intestine is the last part of the gut where the faeces is found and it is supposed to be full of bacteria as the large intestine has a different role to the small intestine.

Leaky gut means that there is leakage of gut contents into the gut’s bloodstream through tiny abnormal breaks and holes in the lining of the gut. This occurs in the small intestine in response to many factors (such as gluten, lectins, saponins and other toxins, and to casein) and can also occur to some degree in the large intestine. I also remind people that “leaky gut starts in the mouth” and it is well known that autoimmune disorders have a bad effect on oral health, and conversely oral disease aggravates autoimmune disorders, all types of inflammation and is also a significant risk factor for heart disease. There can be variations in the leakiness of the large intestine which can be improved by diets with more soluble fibre and resistant starch (this increases large intestine butyrate production which reduces the leak in the large intestine).

For abnormal immune cells to cause real problems they need to be stimulated by proteins that resemble our own tissues. Such proteins are found in Neolithic foods, and in  some bacteria in our gut. This is then amplified greatly if the gut leaks as the proteins can come in direct contact with the immune cells, in wholesale amounts. If the gut is not leaky then there is little opportunity for these proteins to come in contact with the immune cells in the blood stream. The leaked proteins can stimulate the immune system to malfunction both by increasing the general degree of inflammation (the amount of activation of the immune system) or by activating specific squads of immune cells that will attack a particular tissue such as bowel, joint or brain to cause a specific autoimmune disease.

High levels of vitamin D and long chain omega 3 “tune up” the immune system to make autoimmune reactions less common and less severe. Long chain omega 3 comes from animal sources such as fish oil and has many benefits, whereas short chain omega 3 comes from such as flax seed oil. It is not recommended to take flax seed oil as it comes with significant amounts of omega 6 fats which are pro-inflammatory and have negative effects on metabolism.

When food upsets the immune system, there are “two sides of the coin”- disease can occur in the gut itself (such as ulcerative colitis or Crohn’s disease), or it can occur outside of the gut (such as rheumatoid arthritis or multiple sclerosis). However in both cases the illness has been programmed within the gut.

Once it goes wrong, the immune system is very sensitive to tiny amounts of food. This is already well known as people who have food allergies can react to tiny amounts of peanut or egg for example. Any every exposure to the wrong food can increase the effect, every single time. This is probably true with autoimmune disease- for example in patients with severe Coeliac disease, a tiny 1/100 of a slice of bread will reactivate it. Therefore if one is to treat the disease with diet, it can only work with strict avoidance of the suspect food. This requires one to follow what is called a “Paleo diet automimmune protocol”.

Epstein-Barr Virus can be knocked out by retinol, the animal form of vitamin A. Plant forms such as beta-carotene can be converted to retinol but this is very inefficient. Retinol is found in high amounts in liver, kidneys and cod liver oil.

Unfortunately what can be done cannot always be undone, therefore there is no guarantee of success with diet. However, remember that we all have to eat, so why not eat the best possible diet? Also to remember that you can combine the Paleo Diet with your normal medical treatment, so they work together as a club, not in competition with each other. If you do respond to dietary therapy, there is good reason to believe that it will give you many additional health benefits as well as treating the disease you are focusing on.


Paleo food based antibiotics, SIBO and gut health

January 19, 2014

Small intestinal bacterial overgrowth (SIBO) and leaky gut(LG) and insulin resistance(IR) are all hot topics these days.

Robb Wolf brilliantly connected SIBO/LG to IR. http://robbwolf.com/2012/03/09/paleo-diet-inflammation-metformin/

It is also well known that the antibiotic metronidazole reduces leaky gut, thus showing that SIBO and LG overlap/ interact/feed each other. It’s also clear to me that these issues get a life of their own and gradually deteriorate.

I’ve long been aware of the potent antimicrobial effects and broad spectrum of spices (esp cinnamon, cassia and cloves), and of citrus peel extracts (both pith and the essential oils). (NB citrus and spice essential oils may have some toxicity, just saying). Good references for spice antibiotic effects below, and also see enteric coated peppermint oil . And then there are the peels and skins of fruits and vegetables, and these are all full of antimicrobials. This google search shows they are potent broad spectrum antimicrobials. Don’t forget that birds and animals can’t or don’t peel their fruit and vegetables. I found this paper interesting. Abstract pasted below .

Our forebears (and wild primates) used to eat loads of fruit and vegetable peels and skins, and local spices and barks etc. So they used to eat a bunch of natural antibiotics every day, sweeping their small intestines clear of bacteria. So they did not need neomycin or rifaximin or metronidazole or other pharmacological antibiotics. They naturally suppressed the SIBO to keep the small intestine near sterile. The foods in question are then digested and break down somewhat, before appearing in the large intestine where their breakdown products interact with the microbiome there in an ancient cycle. This is in contrast to the pharmacological antibiotics which continue unchanged through the gut (rifaximin and neomycin which are not absorbed nor broken down) or go through the entire body (metronidazole) and destroy large intestinal bacteria en masse.

Even a cursory look at the antimicrobial spectrum of herbs spices peels and skins shows that they are potent antibiotics, with a broad spectrum. There can be no doubt that they must impact the level and type of bacteria in the small intestine, and there is an obvious possibility that they might alter the composition of the large intestinal microbiome.

Allison Seibecker lists a range of antibiotic herbs, on her SIBOinfo website, but I’m just wondering if it might be as simple as not peeling your carrots and citrus, and choosing some herbs and spices etc. Conversely current high levels of SIBO might relate to low dietary levels of these natural antibiotics. So wash 4 oranges then put them through your juicer, throw out the juice and eat the pith!

Abstract (NB streptomycin is a potent antibiotic with a similar antibiotic spectrum to Neomycin): Extracts of ripe, unripe and leaves of guava (psidium guajava); ripe, unripe and leaves of starfruit (Averrhoa carambola); ripe and unripe banana (Musa sapientum variety Montel); ripe and unripe papaya (Carica papaya); passionfruit (passiflora edulis F. Flavicarpa) peel; two varieties of Lansium domesticum peel (langsat and duku); rambutan (Nephelium lappaceum) peel and rambai (Baccaurea motleyana) peel were evaluated for antimicrobial activity against gram positive bacteria, gram negative bacteria, yeast and fungi (Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Lactobacillus bulgaricus; E. coli, Proteus vulgaricus, Pseudomonas aeruginosa, Salmonelli typhi; Saccharomyces cerevisiae, Candida lypolytica; Rhizopus spp., Aspergillus niger, and Chlamydomucor spp). The antimicrobial activities were tested using both the filter paper disc diffusion and tube dilution assays. Extracts from ripe starfruit, guava leaves and rambai peel showed strong activity against all the bacteria tested, in most cases with activity stronger than 50ug streptomycin. Passion fruit peel, ripe and unripe guava showed activity against all the bacteria tested except E. coli. Rambutan peel too showed activity against all the bacteria tested except towards Pseudomonas aeruginosa. Most of the fruit wastes showed some activity towards bacteria but poor activity against yeast or fungi. Extracts from bananas, papayas, passion fruit peel, Lansium domesticum peels and rambutan peels showed activity against Candida lypolytica while extracts from guava showed strong activity against Saccharomyces cerevisiae. Other than guava, ripe starfruit, rambai peel and rambutan peel showed potential for use against bacteria.

Paleo Diet Fights Back- response to US News Health & Wellness rating Paleo diet last.

January 12, 2014

As The Paleo Diet has continued to grow exponentially every year, it is now creating some jealousy and detractors. Its growth is driven by the fact that it is a strong science, whereas most other diets have a weak scientific basis. Due to its strong science, The Paleo Diet works much better than other diets. The latest criticism has been from US NEWS Health and Wellness. Prof Loren Cordain has written a rebuttal to their comments which you can read here. And below is what I have to say on the topic.

The Paleo Diet is not just some diet that some guy wrote one weekend (unlike some diet books). It is a major international scientific movement involving thousands of scientists- doctors, dentists, dietitians, biochemists, physiologists, paleontologists, archaeologists, and other dedicated scientists..  It is the most evidence based and sound diet ever developed, and the only one that is 2 million years old. Because it is a SCIENCE, it can be IMproved but scarcely DISproved. Similarly you cannot disprove chemistry but you can improve it.

Because it is a science, Paleo diet gladly embraces all scientific research. Paleo diet concepts have steadily improved for the past 60 years or so, to the point where it is the most healthful diet known, and unlikely to make major changes in its recommendations.

One of the main tenets of Paleo diet, is that any deviation from the mainstream diet has consequences. We don’t need to go back 10,000 years to prove that changing our diet has consequences- even changes in our food supply in the past 50 years have been disastrous! Consider that in the past 50 years:
-the gluten content of wheat has increased several fold due to selective breeding and other factors. We now have an epidemic of gluten related disease- coeliac disease (1% of the populaton), gluten intolerance (5 to 6% of the population).
-our sun exposure has dropped (a major change in lifestyle from the Paleolithic era) vitamin D deficiency now affects around 50% of the population
-the iodine content of dairy products, added entirely by processing, has dropped 80% and iodine deficiency (around 50% of the population despite recent changes). Authorities now recommend all pregnant and breast feeding women take an iodine supplement unless there is a medical reason not to do so. (reference).
- the increased intake of salty industrial food has contributed to many diseases, particularly hypertension. (reference)
- the flooding of the diet with polyunsaturates has been implicated as the cause of the epidemics of depression, asthma and arthritis. (reference).
-  reductions in choline intake (in conjunction with insulin resistance) have led to an epidemic of fatty liver disease. (reference)

All of these points add up to prove that every change that we make to our diet and lifestyle has consequences, and most are harmful, and the best diet is found by rolling back all the changes to our original diet. This diet already contains everything that all dietitians agree is good for us- more vitamins, more minerals, more fibre, more omega 3, less trans fats, low GI, low salt, high potassium, low in toxins (yes a plethora of toxins have been scientifically identified in many commons foods) the list goes on. No other diet can provide everything in one package- I challenge you to find another diet that does! Similarly when you go over the Paleo Diet, you will find all these questions have been answered.

Sadly The Paleo Diet has some detractors, just as Galileo was opposed in thinking that the Earth revolved around the Sun, and many physicists thought Einstein was wrong. While healthy scepticism is good in science, being a Luddite is not acceptable. Most detractors have a poor knowledge of the science of Paleo Diet or are over-interpreting studies which Paleo Diet scientists are already aware of. Unfortunately most people either “get it” or “don’t get it” immediately, and I have written about why before (click here). If you really want to get “under the hood” of the science, then have a look at research by the 2 leading lights in the Paleo world- Prof Cordain and Prof Lindeberg. Or have a look at the books and websites of Prof Cordain and Prof Lindeberg. Then come back and tell me you’re not convinced LOL!


Blue Paleo- the new Black?

January 16, 2013

I’ve come up with a new shade of Paleo- Blue Paleo! This is the safer way for people who want to get the benefits of raw Paleo without the ickiness of raw. Indeed you can even get sashimi cooked blue now- see below.

Robb Wolf’s blog post of 7 Shades of Paleo is a great list of the most common forms of Paleo diets. Of course, we all know that the ultimate for purists must be the Raw Paleo diet, though few of us would care to venture there. While we all eat fruit raw, and are comfortable eating most Paleo vegetables raw, it is a different matter when it comes to meat (using meat broadly to include meat, offal, fish, chicken etc). We like the security of cooking our meat as it zaps those little nuisances called bacteria, and perhaps we feel it is a little icky from years of social conditioning. Indeed in many countries it is essential to cook your meat and there is nothing you can do about it. Some countries even have tapeworms or pork trichinosis and it is essential not only to cook the meat but to make sure it is well done. However, many of us live in countries like Australia with strong government supervision of food safety where we can be more liberal.

Many of us have eaten raw meats such as sashimi, carpaccio, steak Tartare, oysters, clams and fish eggs. Perhaps you are eating more raw meat than you realised. The French are renowned for eating their steaks barely cooked, perhaps even quivering, but few are bold enough to venture down the hairy-chested road of full raw meat. I have toyed with the idea off and on for years. Indeed I have met some esteemed colleagues who eat raw Paleo (and who follow anapsology in France). These raw Paleo devotees rave about the health benefits and how wonderful they feel, and they look very healthy and energetic.

Scientific discussion of cooking focuses on its effects on bacteria count, digestibility etc, and doesn’t really make a great case for raw. Certainly scientists reject out of hand the notion that we need active enzymes etc in our food as they feel they are generally destroyed by our digestive processes. The most startling evidence in favour of a raw diet was Dr Francis Pottenger Jnr’s Cat experiment- he studied groups of cats fed cod liver oil, meat and milk. If either the meat or the milk were cooked, there were massive health consequences to the cats and their progeny that progressed each generation. Even plants did not grow well on their droppings!

But I keep being drawn back to the concept of raw meat, and here is why: At stages of our evolution we ate completely raw meats, followed by a period where we ate a mixture of raw and cooked meats, and eventually we ate only cooked meats (in many cultures and religions, always cooked well done). Rather than look for research to show that raw has benefits, I would like to reverse the question and ask “what are the consequences of cooking our food, particularly on our metabolism, immune system and our gut?” We don’t really know the answer to that so why not give it a try in planned and safe way.

With this in mind, I had planned to start trying some meat cooked blue- which is less cooked than rare- basically the outside is cooked (sterilised) and the inside is totally uncooked and still cool. The inside of meat should be sterile (however in some countries this cannot be guaranteed particularly for chicken), provided it is not minced or skewered (both unsuitable for blue cooking).

Cooking your meat blue:

  1. Kills bacteria on the outside of the meat
  2. Gives it the same look and colour as fully cooked meat
  3. Has a great mouth feel as it is very tender
  4. Tastes as good or better than fully cooked meat
  5. Will have 100% of the vitamin content without any degradation
  6. Will digest more slowly- both the protein and the fat, as cooking “externalises” some of the digestive process. This explains the observation that many people make that raw meat makes their appetite go away and that weight control happens automatically.

Recently I got to try a blue form of sashimi, called New Style Sashimi invented by famed chef Nobu Matsuhisa at his Nobu restaurant in Waikiki. He has a number of these restaurants and his partners include Robert de Niro. You can see how it is made here. Basically the fresh salmon sashimi (raw fish) is sliced thinly, dressed with various garnishes, and then he heats a mixture of sesame and olive oil, and spoons this over the food to cook its outside on the plate. I can tell you the taste is astonishing, as were the other dishes that my wife Sandra and I ate at Nobu!

Now that I am back in Sydney, the wonderful Nobu taste sensation has spurred me on to finally start on a Blue Paleo diet- so this week it has been all blue meat, mainly lamb, and a few vegetables and a small amount of fruit. I also went low salt for the first time (I should have done so years ago, apologies to my friend the late great Dr Trevor Beard www.saltmatters.org ). Where has my appetite gone? I’ve been mainly cooking in a fry pan, with olive oil, to ensure coating of the meat- such as diced lamb, lamb cutlets, or beef steak. Once the outside has been browned, that’s it. You can look at Google for more on blue steak.

I can only say that if you have been tempted to try raw, just go Blue!

Disclaimer: Consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of food-borne illness, particularly in the elderly, in children and those with immunosuppression or chronic diseases such as gut diseases, diabetes or renal impairment. The risk may be worse in certain countries. If you are unsure, consult your doctor prior to changing your eating habits.


The Lord of the Diets

July 31, 2012

My poetry has been favourably compared to Vogon poetry, so I thought I would rewrite the Lord of the Rings Epigraph as an ode to Paleo.

Paleo, The Lord of the Diets:
Omega 3 for everything under the sky
Vitamins minerals fibre for body and bone
Saving mortal men doomed to die
One free of dark toxins to gut and immune
From the land of the past where our ancestors lie.
One Diet to rule them all, One Diet to find them,
One Diet to unify them all and from the darkness free them
From the land of the past where our ancestors lie.

Ben Balzer

 

 

“Epigraph”, The Lord of the Rings:
Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.

J. R. R. Tolkien
