Obesity & Heredity, Part 4: Epigenetics

I first heard about epigenetics from Dr. Theodore Belfor, the man behind the adult palate expansion device called the Homeoblock.  It is his opinion that epigenetics will be the most important field of science in the next decade.  In brief, epigenetics is the study of  the changes that take place within the epigenome – literally, "on top" of the genome – due to environmental factors, such as food and pollution, without affecting the DNA sequence.  Here's a more lengthy explanation from a website  published by a European group who call themselves “The Epigenome Network of Excellence:”

Conrad Waddington (1905-1975) is often credited with coining the term epigenetics in 1942 as “the branch of biology which studies the causal interactions between genes and their products, which bring the phenotype into being”. Epigenetics appears in the literature as far back as the mid 19th century, although the conceptual origins date back to Aristotle (384-322 BC). He believed in epigenesis: the development of individual organic form from the unformed. This controversial view was the main argument against our having developed from miniscule fully-formed bodies. Even today the extent to which we are preprogrammed versus environmentally shaped awaits universal consensus. The field of epigenetics has emerged to bridge the gap between nature and nurture. In the 21st century you will most commonly find epigenetics defined as 'the study of heritable changes in genome function that occur without a change in DNA sequence.'

Take home quote from above: “...epigenetics has emerged to bridge the gap between nature and nurture.”  This is extremely important in the study of health and nutrition, as there are many questions of what brings about good health and poor health in the context of inheritance, none of which can be fully answered without evaluating specific individual choices – dietary, environmental, etc. – made within each generation (which affects future generations).   In other words, nurture – how we are taken care of as children and how we take care of ourselves as adults  – is what molds and shapes nature – the way our bodies and minds express themselves epigenetically, which is then potentially passed to our children.

How do epigenetic changes take place?  The Epigenome Network of Excellence reporter, Brona McVittie, puts it this way:

The genetic blueprint, like a complex musical score, remains lifeless without an orchestra of cells (players) and epigenotypes (instruments) to express it... Epigenetic factors include both spatial patterns, such as the arrangement of DNA around histone proteins (chromatin), and biochemical tagging...With some 30 000 genes in the human genome, the importance of silence, as with any orchestral performance, must not be underestimated...As cells develop, their fate is governed by the selective use and silencing of genes... Failure to silence genes can produce a hazardous cacophony.

What does all of this have to do with obesity?  Well, scientists have discovered that epigenetic changes in mice that are pregnant mothers can directly impact the health of the offspring.  How?  By turning on or off specific genes through dietary or environmental means.  One of these health effects, in addition to cancer and diabetes, is a tendency of the offspring to become obese as adults.  In one study, if a single gene, called the “agouti gene,” is overexpressed through the failure to suppress another gene (Avy), it greatly influences the ultimate health of the offspring (emphasis mine):

Failure to epigenetically suppress the Avy gene during development causes the agouti gene to be ectopically overexpressed later in life. This high level of agouti expression in essentially all tissues causes numerous downstream metabolic and endocrine effects that ultimately affect gross biological end points such as obesity and survival. This agouti overexpression and its physiological effects have been termed the yellow agouti obese mouse syndrome. This syndrome includes a yellow or mottled yellow coat color, altered metabolism and obesity from a young age. It also results in adult diabetes, increased cancer susceptibility and, by 24 mo of age, twice the mortality seen in normal mice.

Interestingly, whether or not a mouse becomes obese seems to depend on the levels of methyl-donating substances, such as folic acid (a vitamin naturally found in high amounts in organ meats, many kinds of legumes, and dark leafy greens).  The reason behind this has to do with the way that DNA passes information to cells in the body -- a process called  DNA methylation.  Whether or not certain genes are expressed has a lot to do with this process.  Without enough methyl-donating substances, such as the B-vitamins, betaine, choline, SAM-e and genistein (from soybeans), DNA methylation is disturbed and abnormal cell expression, along with switching on or off certain genes, results.  You can see why folic acid supplementation is recommended for pregnant women and why women in traditional cultures consume "sacred" foods rich in methyl-donating nutrients, such as liver, before and during pregnancy.

So, if obese people supplement their diet with folate or genistein, can they reverse the epigenetic changes that may have brought about their obesity?  Short answer: we don't know.  In animal studies, there's more certainty.  Here's what Randy Jirtle, an expert in epigenetics, has to say:

Weaver et al. (Nat. Neurosci. 7: 847-854, 2004) at McGill University, however, have shown recently that maternal nurturing behavior can stably alter the epigenotype in rat pups soon after birth. Moreover, these epigenetic changes are reversible in adulthood following methionine supplementation or treatment with histone deacetylase (HDAC) inhibitors (Weaver et al.Proc. Natl. Acad. Sci. USA 103: 3480-3485, 2006). Thus, data supporting the reversal of environmentally induced epigenetic changes via dietary supplementation or pharmaceutical therapy in adulthood is mounting.

The implications for humans are far-reaching.  Perhaps someday we'll have a way of epigenetically treating obesity, diabetes, and cancer.  For now, the best we can do is eat a nutrient-dense real-foods diet while avoiding processed and refined foods -- the foods that have most likely brought about our health dilemmas in the first place.

For a great overview of epigenetics, check out PBS Nova's educational page on the subject.  Also, here's a nice website by the University of Utah.

SIDEBAR: Is Plastic Making Us Fat?

Aside from diet, another significant factor in the tendency of the agouti mice to become obese comes from the mother's exposure to biosphenol-A (BPA), a common plastic found in many food and beverage containers.  Here's Randy Jirtle again to explain:

We have demonstrated recently that when female pregnant mice are exposed to BPA, the incidence of yellow Avy offspring is markedly increased because DNA methylation of the agouti gene is decreased (Dolino et al.,Proc. Natl. Acad. Sci. USA 104: 13056-13061, 2007). BPA also epigenetically alters gene expression of at least one other gene, indicating a genome-wide effect. Yellow agouti mice become obese in adulthood and have a high probability of developing diabetes and cancer. Consequently, BPA exposure leads to adult diseases in agouti mice by altering the epigenome during the earliest stages of development—a condition that can be counteracted by maternal nutrient supplementation with methyl-donating substances (folic acid, etc.) or genistein.

SIDEBAR: Weston A. Price & Epigenetics

Epigenetics may seem obvious to folks out there who are familiar with Darwin's theory of evolution.  “Of course our bodies and minds are shaped by our environment; and of course we evolve (or devolve) throughout time and generations.  That's the way nature works!”  The big difference, as far as I can tell, is that unlike DNA, epigenetic changes actually take place within one lifetime, not over eons of evolution.  The way the epigenome appears to be altered is by dramatic changes in environment, particularly diet.  Think Nutrition and Physical Degeneration or Pottenger's Cats.

Actually, one might say that Price and Pottenger recognized epigenetics when they observed physical degeneration in the people and animals they respectively studied, although they didn't call it that.  The changes in facial structure and lowered immunity in their studies appeared to be a direct result of poor diet generation after generation.  Once again, during one lifetime, the epigenome can be altered significantly.  Could it be that the mothers and fathers eating a modern diet and the cats eating cooked food altered their epigenome and then passed on these traits on to the next generation?  Is this why each generation appeared to be progressively worse than the last?  The field of epigenetics suggests this is the case.

Adult Palate Expansion

I am deformed.  I look nothing like my ancestors.  As a child, I had braces.  I was a frequent mouth breather.  At age 16, I said bye to my wisdom teeth.  I have only 24 teeth left.  My dental palate is not broad and sweeping; my jaw isn't square; my nasal passage isn't wide.  I'm a human being raised on a processed food diet, and this is the result.  When I first read Weston A. Price's book, Nutrition and Physical Degeneration, it was hard to find out that I'm not developmentally optimal.  I thought, "Well, crud, there's yet another thing that's wrong with me that can't be fixed."  I began comparing photos of myself as a child with some of the photos from Price's book.  Here's me next to a traditional Swiss gal:

See the lack of resemblance?  Check out the overall roundness of the Swiss girl compared to my more narrowed facial structure.  Compare my nasal passage to hers.  Cheek bones?  Jaw?  And, wow, how about them teeth!  This isn't due to genetics, as many of you know.  It's all about nutrition during the developmental years, as Price discovered.  Damn you, margarine, sugar, and white flour!

The other day I was thinking about how it might feel the have the facial features characteristic of the healthy cultures in Weston Price's studies as opposed to the narrow palate, brace-straightened teeth, weak jaw, narrowed nasal passage, and lackluster cheek bones that characterize my own facial structure.  If I were all of the sudden blessed with an optimal facial structure and all the teeth the good Lord intended me to have, would I breath easier?  Speak better?  Smile more fully and more often?  Have less tension in my jaws?  Feel a heightened sense of well-being?  While it's interesting -- if not somewhat depressing -- to imagine such a possibility, I never thought once that this would ever be achievable.  I guess you can say that's why I've come to terms with my deformed self.  I can't change it, can I?  What other choice do I have besides acceptance of my not-so-optimal lot in life?  Sigh.

I was impressed by a study about two twins recently referenced in Wise Traditions, the Weston A. Price Foundation journal.  One twin received palatal expansion, while the other did not.  Here's a photo that shows the dramatic difference in the two -- not just in their teeth, but their overall facial structure:

Impressive, eh?  It's readily apparent that dental appliances can make a huge difference towards regaining the facial structure of our ancestors.  But I'm far beyond the developmental time period during which such devices can help me attain a facial appearance closer to that of the human genetic blueprint, right?  These things only work for the growing child or teenager.  At age 18, the bone plates are fused, and there's no budging them.  Once you're an adult, there's no room for any adjustments, right?  Well, I began to wonder: Is there such a thing as adult palatal expansion?  And, if so, would it make any difference health-wise if I were to apply such technology to my own head?  Let's just find out.  (Google, you are my friend.)

The first website I came across, called Facial Development, is absolutely fascinating.  It's authored by Theodore R. Belfor, DDS, who has a clinic in New York state that actually specializes in expanding adult palates using a dental appliance called a Homeoblock.  From his website:

The Homeoblock™ appliance is a revolutionary patented oral device that is much like a retainer in looks, but the results go way beyond teeth straightening...The Homeoblock™ appliance works with the body, so that physiological changes occur naturally; developing the bones of the face and resulting in the strengthening of facial muscles. These changes occur due in large part to each person’s genetic potential  Often, facial development does not reach its potential due to the food we eat, polluted air and poor dental care to name a few.

Wow.  A dentist who acknowledges that facial development is influenced by diet?  I wonder if he knows about Dr. Price.  Browsing the website further, I came upon a paper that Dr. Belfor wrote called, "Facial Changes as a Result of Palatal Expansion in Adult Patients Using the Homeoblock Appliance."  Check out this before and after 3d image taken of one of his patients who used a Homeoblock:

Look closely and notice the differences in the cheek bones, chin, and lips.  Pretty incredible.  So not only does palatal widening make for straighter teeth, it also induces significant changes in the overall facial structure -- even in adults.  Dr. Belfor markets his work as a way of creating a more youthful appearance in addition to straightening teeth.  An interesting effect of palatal widening is reduced wrinkles.  But he's also very enthusiastic about other changes that occur with the procedure (emphasis mine):

 I am experiencing the most incredible excitement on a daily basis. I routinely expand adult underdeveloped maxilla and mandible taking the teeth along for the ride. There are many different goals, as many as there are different patients. However, the result is always the same; more prominent cheekbones, wide smiles, and strong jaws!"  

Prominent cheek bones?  Wide smiles?  Strong jaws?  Is this guy Weston Price incarnate?  So, wait a minute, how can any of this actually work if the bones are fused by age 18, as is commonly believed?  Well, let's let Dr. Belfor answer that one:

Bone is essentially plastic in nature. Tension and intermittent pressure persuade the bones to redefine at any age. In fact, our typical patient is between 30 and 60 years old. In the upper dental arch nature has provided a suture line front to back between the two bones that form the palate. This allows for an easy widening process and as the palate expands, the cheekbones as well, creating more prominence.

Okay, so maybe there's a chance for a "deformie" like me to experience optimal facial structure after all!  I would like a second opinion, though.  I  mean, isn't there a possibility of teeth relapsing or other complications happening?  Let's see what one scientific study had to say about adult palatal widening procedures and the risks involved, in this case using an implement called a Haas expander:

Rapid maxillary expansion (RME) in the adult is thought to be an unreliable procedure with several adverse side effects and, consequently, surgically assisted RME is considered the preferred procedure...Rapid maxillary expansion using a Haas expander was examined in 47 adults and 47 children...The results indicate that nonsurgical RME in adults is a clinically successful and safe method for correcting transverse maxillary
arch deficiency.

This study had a follow-up time of an average 5.9 years, and the patients' teeth remained in place.  Here's a dramatic before-and-after image from the study showing one case of palatal expansion, a 30-year-old female:

Now that's just amazing.  30-years-old and there's still room for correction of the dental arch.  I wonder, though, are there any health benefits to having the palate expanded and the resultant craniofacial changes that take place?  Dr. Belfor, what do you think?

Orthopedic jaw development, particularly arch expansion, allows for improved sinus drainage and widens airflow passages. This can result in snoring reduction and lessened symptoms of sleep apnea...Voice enhancement. Improved facial balance and skin tone. Arresting and reversing the premature aging of the face. 

 Sounds to me like it would be worth it.  Only one problem, I have no idea how much the procedure actually costs.  I'm sending an e-mail to Dr. Belfor to find out.  Also, I'm going to ask him if he's influenced at all by Weston A. Price, as he seems right there with the 1930s dentist philosophically.  If anybody out there has more information on the procedure, please leave your comments.

Here's one more link with an article and video on adult palate expansion: "Skull Stretching."

Primitive Nutrition Talk: Health Stories

Here's the first of a series of videos from my discussion/presentation on Primitive Nutrition, which took place at the Wintercount Rendezvous 2010.  In this video are a few of the diet experiences shared by folks that sat in on the talk, as well as my own health story.  I'll be publishing more videos of this presentation in the coming weeks, covering many nutrition and health topics from an evolutionary and anthropological perspective, as well as diving into the work of Weston A. Price.

By the way, if anybody knows how to sync video and audio, I'd greatly appreciate some advice, as you can see that the second half of the video is a few seconds off.

Video Footage of Weston A. Price

I'm currently working on crunching some numbers to put together part two of the "Small Game in Primitive Living" series and will hopefully finish it soon.  Until then, I thought I'd post this video I came across on YouTube the other day.  It's a segment from an odd, somewhat dated television show -- public access, I'm guessing -- called "Homekeepers."  The host is interviewing a woman -- a "Certified Nutritional Consultant" -- who describes the findings of Weston Price.  I'm not sure who this woman is or what she's all about (besides the fact that she's very politically correct when it comes to nutrition) but I'm very grateful that she dug up some fascinating video footage of Price.  If you want to skip the interview (which I would recommend) and go straight to the press release footage of Price, fast-forward to 3:26.

 

The People of the Deer

Lately I've been enjoying an anthropological narrative called People of the Deer by Farley Mowat -- the famed and tenacious environmentalist, humanitarian, and defender of true scientific inquiry. In this colorful true-story adventure, first published in 1952, Mowat finds himself drawn, as he so often does, to a place far away in the middle of nowhere in the deep northern territories of Canada. It is here that he befriends and lives among an Eskimo group called the Ilhalmiut and begins to understand how modern encroachment -- namely fur-trapping and government policy -- is negatively affecting the native peoples' ability to live in a place where their ancestors had thrived for thousands of years before them. Mowat writes, quite bluntly, in the foreward of the 1975 edition of the book: "Genocide can be practiced in a variety of ways." Similar to Weston Price, he is not hesitant to place blame on Western culture for the decimation and struggle of the traditional peoples with whom he became intimately acquainted. From the foreword:

We have long prided ourselves on being a democratic nation, dedicated to the altar of freedom. Freedom for whom? If it is only freedom for ourselves to do as we please at the expense of others, then our pious stance is even more abhorrent than that of any overt tyrant -- for ours is based on a vile hypocrisy.

Fat and Deer Hairs

While the book contains many fascinating tidbits, among the most intriguing are Mowat's detailed descriptions of the traditional Ilhalmiut diet and their shifting health as a result of Western influence. When he first arrives at the small settlement of Ilhalmiut, the author is welcomed with a tray of meat that might make any Westerner's stomach churn:

Half a dozen parboiled legs of deer were spread out in a thick gravy which seemed to be composed of equal parts of fat and deer hairs. Bobbing about in the debris were a dozen tongues and, like a cage holding the lesser cuts of meats, there was an entire rib basket of a deer.

Still hungry? There's more!

There were side dishes too ... a skin sack, full of flakes of dry meat ... a smoking bundle of marrow bones ... neatly cracked to so that we would have no trouble extracting the succulent marrow. (p. 82)

Yum.

The cooking varied somewhat, but the food did not. The rule was meat at every meal and nothing else but meat, unless you could count a few well-rotted duck eggs which served as appetizers. To satisfy my curiousity I tried to estimate the quantity of meat Hekwaw [a member of the tribe] put away each day. I discovered he could handle ten to fifteen pounds when he was really hungry... (p. 85)

It doesn't take Mowat long to identify the key ingredient of the Ilhalmiut diet: fat. From his own experience on lean meat for an extended period of time, he describes the vast importance of fat in an all-meat diet through his battle with an affliction which he names, for want of a better term, mal de caribou, also known by a great many arctic explorers, prisoners of war, and human carnivores as rabbit starvation:

... persistent diarrhea was only part of the effect of mal de caribou. I was [also] filled with a sick lassitude, an increasing loss of will to work that made me quite useless ...

Mowat's guide -- a half-Eskimo, half-white man named Franz -- prepared and administered a peculiar remedy:

... he took out a half-pound of precious lard, melted it in a frying pan, and, when it was lukewarm and not yet congealed, he ordered me to drink it. Strangely, I was greedy for it ... I drank a lot of it, then went to bed; and by morning I was completely recovered ... I was suffering from a deficiency of fat and did not realize it. (p. 88)

Death and Disease Among the Ilhalmiut

Concerning the health of the Ilhalmiut people, Mowat goes into extensive historic, anecdotal, and statistical detail while attempting to get at the root of the Northern natives' plight of disease and illness following the arrival of Western culture. It's no secret to those who have studied into the writings and theories of nutritional heroes such as Weston Price, Sir Robert McCarrison, T.L. Cleave, and others that when modern foods such as white flour and sugar are introduced to a traditional culture ill health follows, worsening from generation to generation. Farley Mowat joins the ranks of these great independent thinkers when he waxes sensible, explaining his own theory as to why the people of the far North and other native peoples in history have succumbed to tuberculosis, measles, and small pox:

Perhaps you have heard of the decimation of the forest Indians brought about by disease, by lack of adaptability, by inherent laziness and indolence or by other causes ... you have never heard the truth, for all of these apparent causes are manifestions of the real destroyer, which is -- starvation. If you ask about the thousands of Indians and Eskimos who die each year of tuberculosis, if you ask about the measles and smallpox epidemics which ... have destroyed over one-tenth of the Northern natives ... these people too die of starvation ... (p.91)

Is it just me, or is Mr. Mowat on to something here? He goes on to tell the story of an Inuit tribe he lived with in the winter of 1948, the Idthen Eldeli -- literally meaning "Eaters of the Deer":

In 1860 ... there were about 2000 members of the Idthen ... when the deer moved ... the Idthen people followed after ... [they] anually traveled over a thousand miles through the Barrens.

In the eighteenth century the famous explorer Samuel Hearne journeyed ... with a band of these Indians and he speaks, as do many others, of the almost superhuman endurance and physical capacity of the Idthen people.

In the winter of 1948 when I lived with the Idthen ... they numbered a little over 150 men, women, and children who spent the winters on their scanty trap lines, starving through the cold months until they could fish for life along the opening rivers ... They are a passive, beaten, hopeless people who wait miserably for death. (p. 92)

What could be the instigator of such an unfortunate circumstance? Ol' Farley doesn't mince words:

Starvation first came to them when they began to subsist on a winter diet which now consists of 80 percent white flour, with a very little lard and baking powder, and in summer almost nothing but straight fish. The Idthen people now get little of the red meat and white fat of the deer, once their sole food. Three generations have been born and lived -- or died -- upon a diet of flour bannocks and fish eaten three times a day and washed down with tea. Each of these generations has been weaker and had less "immunity" to disease than the last. (p. 93)

Government aid: giving natives the short end of the stick in America since 1492. It's interesting how what Mowat refers to as starvation can also be seen as a displacement of native foods, as Weston Price pointed out in the 1930s. Either way, the result is lowered immunity and degeneration. Mowat's solution for the dilemma of this "starvation?" Here it is, in characteristic common sense:

Surely there is but one way to cure a man of the diseases which are the products of three generations of starvation, and that is to feed him. (p. 95)

Let them eat meat and fat!

The Darwin of Nutrition

Here is an excerpt from an article I wrote called, "Weston A. Price: A Search For True Health," recently published in The Bulletin of Primitive Technology, Spring 2009.

Following the realization that food was the major contributing factor in human health and disease, Weston Price kept a keen eye out for what specific foods seemed to keep the primitives in good health. It was already obvious that industrialized foodstuffs weren't supportive of optimal health, so now it was Price's mission to determine what particular “nutritional programs” contributed to the well-being of the primitive groups. What food traditions had thousands of years of trial and error resulted in? Dr. Price noted every culture's dietary habits, including special foods utilized during times of child-rearing for the man and woman. It impressed him that the primitives seemed to be aware of preventative measures beginning with the health of the parents:

A very important phase of my investigations has been the obtaining of information from these various primitive racial groups indicating that they were conscious that [physical degeneration] would occur if the parents were not in excellent condition and nourishment. Indeed, in many groups I found that the girls were not allowed to be married until after they had had a period of special feeding. In some tribes a six month period of special nutrition was required before marriage. (Nutrition & Physical Degeneration, p. 3)

Dr. Price was convinced by the ubiquitous nature of this practice that many ailments of modern civilization were caused by prenatal undernourishment and that many of these problems could be prevented by the proper nutritional reinforcement of the parents to be.

Curious about the nutritional content of the primitive diets – particularly those that were emphasized for child-rearing – he took several samples of foods from each locale in order to test them at his laboratory in the United States. Armed with such information, Dr. Price believed that he could then determine what all the varied diets of each culture had in common and further understand the nutritional wisdom of the primitives. When he analyzed the traditional foods, he was excited to find that, on the whole, foods in the native diets were four times richer in water-soluble vitamins and minerals and ten times richer in fat-soluble vitamins than the industrialized American diet of his day. Of the native foods studied, Price realized that the foods which the primitives most emphasized and often times considered sacred (especially for child-rearing) were rich in “fat-soluble activators:” vitamins A, D, and what he referred to as “activator X” – now understood to be vitamin K2. This included foods such as fish eggs, liver, certain insects, and other cholesterol-rich, fat-rich foods (see table below; foods high in fat-soluble vitamins are in bold).

The qualities of the foods, Price came to realize through testing native foods as well as conducting experiments in his laboratory, depended greatly on the quality of the soil and the feed given to the animals. For example, grain and hay-fed dairy products in the United States had far less vitamin and mineral content when compared with dairy products from the Swiss in Loetschental Valley, which was produced from cows grazing on “rapidly growing green grass” in the spring and summer and chlorophyll-rich hay in the fall and winter. Price determined that the color of the butterfat from such dairy products could accurately predict the nutrient-density: a deep yellow or orange color reliably indicated high vitamin content. The laboratory tests of traditional foods further bolstered his confidence in the “wisdom of the primitives.”

Health Profile: Geronimo

A well-known Chiricahua Apache and leader of his people, Geronimo is most recognized for his bouts with -- and escapes from -- Mexican and U.S. military troops in the mid to late 1800s. Among the Apache, Geronimo was thought to have great powers, including the ability to see into the future and leave no tracks when moving through the mountains and deserts of his tribe's territory. His band of Apache warriors were among the last Native American peoples to surrender to the U.S. government and live on reservations.

Tales of Geronimo's cunning retreats from his military pursuers abound. One story holds that Geronimo and his band disappeared without explanation when trapped in a cave that had no second entrance. On horseback, he and his warriors were able to keep ahead of the U.S. cavalry -- with its horses and loads of supplies -- at a pace of 70 miles a day while carrying very little and living on wild plants and animals, even resorting to killing their own horses for sustenance. During battles, Geronimo was shot and wounded several times yet never succumbed to death from a bullet wound.

In short, the man was -- like most traditional native peoples of his time -- quite a specimen.

Looking at his photos, Geronimo's beautiful facial structure -- round face, square jaw, prominent cheek bones, wide flaring nostrils -- is readily apparent. This indicates a full and proper development during his formative years as an infant, young boy, and teenager. (We can't comment on his teeth as he never smiled in photos, but he probably had all of them.) His broad shoulders and upright posture suggest agile movement and strength. Like a wild animal, Geronimo was optimally built for his rugged environment of high mountain sky islands and vast seas of low desert. Having lived near, and backpacked through, the Chiricahua Mountains in southeastern Arizona (Geronimo's former stomping grounds) for several months, I can attest to the ruggedness of this landscape.

Lifestyle plays a major role in the fitness levels of Geronimo. Traveling on foot or horseback for up to 70 miles, stalking wild game, and crafting tools and shelters from his surroundings, he spent his life using his body. This lifetime "use" was certainly a major contributing factor to his physical capabilities. Yet, perhaps he wouldn't have been as capable -- his body not as supported, his build not as solid, his immunity and ability to recover from bullet wounds diminished -- if he hadn't also eaten the natural, primitive diet of his people. What kind of diet was that? Here's a list of some of the staple foods that the Apaches ate and the nutritional qualities that make them supportive:

• Wild game: deer, elk, quail, rabbit, etc. --> utilizable proteins and fats, which provide amino acids, b-vitamins, fat-soluble vitamins, and, when using the whole animal (as was common in Geronimo's day), every single needed nutrient the human body needs. (Interstingly, the Apaches had taboos against eating snakes, frogs, fish, and bears.)
  
• Corn, beans, and squash--> starchy carbohydrates traditionally processed to eliminate anti-nutrients (fermented, roasted, soaked, leached, etc.) providing supplemental energy and sparing fat loss; additional vitamins and minerals (for an interesting account of how Apaches prepared a fermented corn drink called tizwin, see bottom of this post)
• Agave--> heart of the plant pit-roasted, young stalks eaten; provides supplemental starch and sugars in the diet; spares fat loss ... but gives horrible gas (I can attest to this myself after eating a pit-roasted agave -- yeesh!)
  
• Acorns & Pine nuts--> roasted, soaked, leached, pounded, or eaten fresh (some species); beneficial proteins and fats; particularly rich in monounsaturated fatty acids
  
• Prickly Pear Cactus--> fruit cooked into syrup or eaten fresh and young pads boiled or roasted (high in oxalic acid raw); fruits rich in electrolytes for a hot, dry climate; pads rich in calcium and vitamin A beta-carotene

Really, if we break it down, we find that the Apaches were quite omnivirous much like other hunter-gatherer tribes across the world (Australian Aborigines and Bushmen of the Kalahari come to mind). Geronimo's very supportive, nutrient-dense Apache diet of meat and properly prepared plant foods allowed for the full facial and skeletal development -- as well as the mental sharpness and alertness -- common to traditional peoples eating a traditional diet (see Weston Price's studies for more on this).

So, it seems that the famous Apache leader lived healthfully with vigor and "fierceness" (as many accounts report) throughout his life. But what of his lifespan? Does it fit the description, "nasty, brutish, and short?" Not in the least. Geronimo lived from 1829-1909, dying at age 79 from pneumonia after drunkenly falling off his horse and contracting a severe cold. Had his life not been cut short by this accident, perhaps he would have lived well into his 80s or 90s.

"I cannot think that we are useless or God would not have created us. There is one God looking down on us all. We are all the children of one God. The sun, the darkness, the winds are all listening to what we have to say."

Making "Tiznin" -- An Apache Fermented Corn Drink

"First, they soaked the corn overnight in water. They dug a long trench and lined it with grass, placed the soaked corn in the trench, and covered it with another layer of grass. Sometimes they covered the whole with earth or a blanket. After sprinkling the corn with water morning and evening for ten days, during which it sprouted, they took it out, ground it with their grinding stones (mano and metate), and then boiled it for five hours. Finally, they strained off the liquid and set it aside. After about twenty-four hours, when it stopped bubbling, it was ready to drink." (From Geronimo: The Man, His Time, His Place by Angie Debo, p. 22)

So What's For Dinner?

Part 5 from my paper, "Modern Health, Primitive Wisdom: American Health History and the Findings of Weston A. Price."

"Meat, potatoes, and gravy. I don't like vegetables; I can't hardly eat any of them. The potatoes take care of all the vegetables."

-- Lena Stanley, Centenarian (Edelman 1999, p. 378)

The world of human health and nutrition is a bewildering labyrinth at times. Just about everybody has their own idea of what is and isn't healthy, and there are plenty of diet books, doctor's recommendations, health gurus, and dieticians out there to guide the way. Who is right? Who is wrong? What is the optimal human diet? It is questions such as these that can stir up confusion and debate. Yet, nutritional science is still in its infancy, having only been in the public light since the late 18th century. There is plenty of room for confusion and debate. As one nutritionist says, "It's all theory" (A. Minear, personal communication, January 17, 2007).

If we are to only work with what the last 100 hundred years of research and science has told us about how the foods we eat affect our health, we are left with but a small period of time upon which to base our ideas -- we only see how food has affected human health over a millisecond of the time that people have been eating. During this brief period of history, we have conducted multitudes of studies that make very convincing arguments for or against certain aspects of nutrition. An interested, research-oriented individual can find in books, articles, and journals many studies supporting a low-fat, high-carbohydrate way of eating, for example. That person can also find many resources that support the complete opposite -- extolling the benefits of high-fat, low-carbohydrate diet. Add in the varied interpretations by the scientists involved in these studies, as well as the opinions of independent researchers, the media, doctors, nutritionists, friends and family -- and that's when bewilderment arises.

This is where Weston A. Price comes in. His research and conclusions are drawn from a combination of modern and ancient dietary wisdom. The traditional population groups he studied had all been eating a certain way for thousands of years. With the aid of modern science, Price found that the foods these people ate provided needed nutrients in consistent quantities to allow for optimal growth and development -- and these foods worked for these cultures over thousands of years. In studying nutritional science, why work with only a miniscule piece of human health history (as in the last hundred years) when there exists a firm foundation in the dietary wisdom of primitive peoples -- a foundation built over thousands of years? In interpreting our own health, why not look to our ancestors and ask what kept them free from degenerative diseases? Dr. Barry Groves, a health researcher and author, puts it this way:

We should not be looking for answers to the diseases we suffer from today, but why many peoples in the world don't get them at all. That way we might stand a better chance of an answer to the dreadful plague of ill-health we are beset with.

It is extremely important for our modern world to acknowledge the findings of Weston A. Price. In considering Price's discoveries of healthy traditional cultures, we have the basis for a logical advancement in modern medicine: the creation of a benchmark that describes what true health looks and feels like. This is something that does not currently exist in the medical establishment. Though we have many tests and procedures to determine whether or not a patient is "normal" or "at-risk" for disease, we have no set standards for optimal human development. This was Price's idea in the first place: he wanted to find "control groups" of healthy populations who were not suffering from the physical and mental malfunction of his day -- he wanted to define what it meant to be truly alive and healthy:

Instead of the customary procedure of analyzing the expressions of degeneration, a search has been made for groups to be used as controls who are largely free from these affections (p. 1).

And this is what Weston Price found in primitive peoples across the world. He found in these people a new standard for human potential. But how can we define such a standard in a world where disease and deformities are the norm?

Like Price, we simply observe the people who are actually healthy. When we look at the photos that Dr. Price took during his travels, we witness a level of physical and mental well-being simply unknown to most modern human beings. When we see those broad faces, perfect teeth, and -- as Price stated again and again -- high moral character of primitive peoples, we are observing a higher degree of human health. It is readily apparent that primitive peoples have many qualities that modern people do not possess. Through the observation of these ancient cultures, whether through books, photographs, documentaries, or travel, it isn't hard to see that they are different -- and not just culturally. We can gain immense benefit from observing these differences and determining what they possess in health and well-being that we do not.


Minds and Hearts

Let us consider the way primitive people use their bodies and minds: how they respond to excitement or danger, the values they live by, the nature of their temperaments, and the way they breathe, eat, play, and live. Are they hyper-anxious? Do they steal, cheat, and murder? Do they have nagging physical problems, such as back, neck, and shoulder tension? In large part, the answers are: No, no, and no. We moderns can use the answers to such questions -- and the implications therein -- in the betterment of our own health. In addition to subjecting the "control groups" of healthy indigenous people to medical tests, let us also communicate with these people and sense with our hearts the degree of their well-being. Let us observe closely what separates them from us in body, mind, and spirit. And let us ask what we can learn from these differences.

Perhaps a good start would be to eat the way our ancestors did. In returning to the food traditions of antiquity in the United States, we have a chance to restore our health. Much has changed in American food habits over time. Most people would say that our nutrition has improved immensely in modern times; after all, we have progressed in technology, medicine, and hygiene -- isn't it obvious that we would have enhanced our nutrition as well? With all of the knowledge that we have accumulated in the sciences, children are still being born with facial and dental deformities. These deformities are not questioned so much as they are accepted. In fact, they aren't even referred to as deformities as they were in Weston Price's day, and they are not at all believed to be connected with nutrition as Price's research revealed.

In the U.S. these days, it is just part of life to have your wisdom teeth removed, have a narrow face, get braces, or develop a chronic health condition. We assume we are advanced enough to know if something isn't right with human growth and development. Yet again, how can we know that something isn't right if we don't have any clue as to what is "right" in the first place?

Once again, traditional peoples like our American ancestors paint a picture of how human beings are meant to be. Our ancestors provide -- through their facial and skeletal development and lack of degenerative disease -- an example of close-to-optimal health. I say "close-to" because Americans at the turn of the century still did not match up to the vibrant glow of the aforementioned primitive cultures of Price's studies, all of which were completely free from disease and deformity. However, early Americans were far healthier in many ways than we are today. And, as was suggested earlier, all things in consideration: early Americans' lifespan closely matches the life expectancy of today.

Once we observe the characteristics -- physical, mental, and spiritual -- in traditional peoples across the world, it is readily apparent that modernized populations are sorely lacking. It is only sensible then to ask how traditional peoples attained such refined attributes. It was apparent to Weston Price that diet was a key factor, and this is my assertion as well. Centuries of nutrient-dense foods have allowed for the creation of superb human beings in traditional societies:

One immediately wonders if there is not something life-giving in the vitamins and minerals of the food that builds not only great physical structures within which their souls reside, but builds minds and hearts capable of a higher type of manhood ... (p. 27).

The "minds and hearts" of primitive people provide our modern civilizations with a lucid, inspiring picture of what true health is. We are given a wonderful opportunity to observe these examples and ask how we can attain this health through employing traditional food habits and following the wisdom that our ancestors have left for us.

What About Cholesterol?

Here is Part 4 in a series of blog posts adapted from my paper, "Modern Health, Primitive Wisdom: American Health History and the Findings of Weston A. Price."

It is commonly believed that saturated fat and cholesterol are primary culprits in the current heart disease epidemic in the United States. We have already taken a look at saturated fat, but what about cholesterol? Is there any substantiation behind the claim that a high-cholesterol diet leads to clogged arteries or dangerously high blood cholesterol levels? What about early Americans and other traditional people who ate cholesterol rich foods and did not suffer from heart disease?

Returning to Weston Price's studies of traditional cultures, one finds that the most prized foods were very rich in fat and cholesterol. Some of these foods include liver, butterfat, fish eggs, and a variety of rendered animal fats, such as lard, tallow, and chicken fat. These cholesterol-rich foods are also rich in fat-soluble vitamins, the catalysts responsible for proper protein and mineral assimilation, and may be the key to rearing healthy children with round faces. Price found no evidence of heart disease, cancer, and other degenerative diseases in the people who enjoyed such nutrient-dense foods. On the contrary, he found primitive people to be the most vibrant and healthy people he'd ever seen.

Like other traditional cultures, early Americans saw no reason to avoid cholesterol-rich foods. They savored hearty, nutrient-dense foods that were high in cholesterol. Butter, cream, egg yolks, lard, tallow, and untrimmed animal meats (including organs) were not disdained -- these foods were thoroughly enjoyed and used extensively in recipes of all kinds. Before the advent of nutritional sciences and USDA food pyramids, turn-of-the-century Americans were enjoying such foods while having no knowledge of cholesterol and its function in the human body. They were unknowingly supplying their bodies with a nutrient that is very supportive to good health.

Cholesterol is not a fat -- it is a waxy alcohol that is not utilized for energy by the body; it does not supply calories. Rather, it is absorbed directly by the intestinal wall without needing to be broken down like fats, proteins, and carbohydrates. The amount that is absorbed by the body generally amounts to less than 50%. Cholesterol plays a key role in brain growth and development (especially in infants), cell membrane integrity, and the healing processes of the body -- thus, it is usually present in scar tissues where there is a repair process happening, as in arteriosclerosis (scarring of the arteries). In addition to all of these functions in the body, cholesterol is the raw material for our hormones. This includes sex hormones and adrenal hormones (also known as "stress hormones"). The adrenal hormones are especially needed in the modern world where stress is a constant part of our lives (Enig, 2000, pp. 48-50, 56-58).

The story of how such a vital nutrient went from being revered in the early century, to being maligned and feared in modern times, is well-documented in The Cholesterol Myths, by Uffe Ravnskov. In this book, Ravnskov makes it clear that there is very little reason for Americans to fear the theory that dietary cholesterol contributes to heart disease and high blood cholesterol levels (the diet-heart theory). (Interestingly, according to the author, blood cholesterol levels may not have any pertinence in evaluating the risk of heart disease.) Several population groups are cited by Ravnskov that consume substantial amounts of cholesterol-laden foods and do not have heart disease or high blood cholesterol levels. This includes both modern and primitive populations. It is also noted by Ravnskov that the studies upon which the diet-heart theory are based are either flawed or skewed to prove the truth in the theory.

One of the pillars of the diet-heart theory is The Framingham Heart Study, which is often referred to as proof that high cholesterol levels lead to a greater risk of heart disease. Ravnskov found this study to be flawed in a number of different ways. The director of The Framingham Heart Study had this to say about the final results of the project:

In Framingham, Massachusetts, the more saturated fat one ate, the more calories one ate, the lower the peoples' serum cholesterol ... we found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories weighed the least and were the most physically active (as cited in Enig & Fallon, 2001, 5).

Such inconsistencies in the diet-heart theory have spawned an entire network of scientists, researchers, and health professionals who call themselves The International Network of Cholesterol Skeptics, or THINCS. This organization has among its members many reputable individuals who have taken it upon themselves to disseminate unbiased information and engage in discussions concerning the science and health effects of dietary cholesterol. Armed with this information, the interested individual can arrive at his or her own conclusions about whether or not one should worry about cholesterol in the diet, as well as determine whether or not high-cholesterol foods were detrimental to early Americans.

Big, Fat Changes in American Foods

Part 3 in a series of posts adapted from my paper, "Modern Health, Primitive Wisdom: American Health History and the Findings of Weston A. Price."

Over a hundred years, we have conquered tuberculosis and pneumonia, improved safety measures in work environments, developed methods to increase food supply, and improved infant survival rates. Yet the quality of our lives is now diminished through conditions such as diabetes, heart disease, and cancer. These changes in disease patterns over the last century correlate strongly with changes in diet. Aside from an increase in processed food consumption since the early 1900s, our consumption of fats and oils has shifted quite dramatically in terms of quality (not so much quantity, contrary to popular belief). In other words, the type of fats (animal, fruit, and vegetable) and specific fatty acids (saturated, monounsaturated, and polyunsaturated) that Americans ate one hundred years ago were very different from those that are eaten today. The table below provides an overview of the changes that have taken place.



Much of the fats that Americans have eaten for centuries -- and that many traditional cultures have eaten for thousands of years -- have been mostly saturated and monounsaturated. Animal fats top the list in 1890 as the fat of choice for cooking, baking, and spreading. Yet, heart disease (commonly believed to be caused by animal fat consumption) was far less prevalent during this era. In 1990, we see vegetable oils are leading the way, while animal fat consumption is so minimal that it does not make the list. For the first time in history, people are ingesting large amounts of polyunsaturated oils extracted from seeds and grains. These oils are often unknowingly eaten in prepackaged foods, as they are the oil of choice for the modern food industry due to their cost-effectiveness. Most potato chips, for example, use corn, canola, or soybean oils -- none of which were consumed in significant amounts by our ancestors.
As the type of fats and oils that the United States consumes has changed in the last 100 years, degenerative diseases have became more and more common. Saturated fat consumption has been blamed for causing many modern diseases. Modern Americans are claimed to be eating too much saturated fat and have been encouraged to cut back as much as possible to prevent disease. Is saturated fat to blame? If it were, one would expect the consumption of saturated fat to have increased substantially since the early century. This has not been the case, however:

Over the course of the 19th century, as heart disease has increased and cancer has become a common cause of death in the United States, saturated fat consumption has remained quite stable. Monounsaturated fat consumption has increased substantially. Yet this change pales in comparison to the growing popularity of polyunsaturated fat in the American diet. In the 1950s, with polyunsaturated vegetable oils gaining favor by the edible oil industries (whose primary motivation was to make a profit), Americans began eating more and more of these unnatural, man-made fats -- fats which were traditionally only consumed as whole foods, such as grains, vegetables, seeds, and nuts.

In her book, American Food Habits in Historical Perspective (1995), Elaine N. McIntosh states: "Essentially, the consumption of animal fat has declined since 1940, and the consumption of vegetable oils has increased steadily since 1909, overtaking animal fats in 1950" (p. 210). The transition from a diet rich in saturated and monounsaturated fatty acids (mostly from animal fats) to a diet high in polyunsaturated fatty acids (vegetable oils -- many of which are hydrogenated trans fats) has been one of the most significant changes in human nutrition in the past 100 years.

Next, Part 4: "What About Cholesterol?"

Were Early Americans Really Living Shorter Lives?

This is Part 2 in a series adapted from my paper, "Modern Health, Primitive Wisdom: American Health History and the Findings of Weston A. Price."

Looking deeper into the life expectancy statistics that are used to gauge our country's health status, one quickly finds that it is not a simple black-and-white procedure. Many factors create discrepancies in the data. One prime example is the role that infant mortality rate plays in determining life expectancy data. As the mortality numbers of the overall population are added up, every infant death contributes a "0" to the tally, significantly impacting the final average. Below is a graphic representation of the result of this phenomenon. (blue = infant mortality; yellow = average lifespan.)


In the above figure, we see that infant mortality rates in 1900 are quite high at 14 %. Correspondingly, average life expectancy of newborns in 1900 is very low at 47.6 years. In 1992, with infant deaths (along with infectious disease, undernourishment, and death from injury) being largely controlled by medical technological advancements, the infant mortality rate drops drastically to less than 1%. For that year, we find that life expectancy has risen by nearly 30 years compared to data from the year 1900.

It is also important to note that the data for life expectancy in the above figure is only representative of the number of years a newborn infant is expected to live. In other words, at age "0" a white person in 1900 is expected to live up to 48 years; in sharp contrast, a white person born (age "0") in 1992 is expected to nearly 77-years-old. However, if the 1900 person escapes infectious disease, injury, miscarriage, and undernourishment and manages to reach 40-years-old and beyond, the numbers shift significantly (blue = 40+ life expectancy in 1900; yellow = 40+ life expectancy in 1992):


Here we see that if a white American in 1900 reaches age 40, he/she can expect to live 28 years longer (age 68). A white American in 1992 is expected to live 39 years longer (age 79). This is a difference of 11 years. Furthermore, if the 1900 person should live to age 80, he/she is expected to reach age 85. If the 1992 man lives to 80 years, he can expect to see age 87. This is a difference of 2 years. Thus, it can be seen in the above figure that as the age of the individual increases, the gap between the life expectancy data of 1900 and 1992 diminishes. Returning to the first figure, which is based on newborn (age 0) life expectancies, we find a much larger gap in the data -- a difference of nearly 30 years.

Once again, we must remind ourselves of the many changing factors over the century that play an important role in interpreting this data: better hygiene, control of infectious disease, increased food supply, and improved infant outcome. Such influential factors must be taken into consideration when using lifespan data to analyze the health of the United States population throughout the century.

American Health Then & Now

This blog post is adapted from a paper I wrote in 2007 called, "Modern Health, Primitive Wisdom: American Health History and the Findings of Weston A. Price." Enjoy!

One dietary characteristic that was readily apparent in the traditional primitive cultures of Weston A. Price’s studies was the lack of modern, processed foods. There was in these cultures a widespread use of foods high in nutrient content and comparatively low in calories. When processed foods replaced traditional foods, physical deformities and ill health followed. This pattern of less consumption of nutrient-dense foods and greater consumption of processed modern foods has happened in the United States just as it has in the primitive cultures of the world.

A look around the American population with Dr. Price’s discoveries in mind quickly reveals the state of health in our country today. It's common for modern Americans to require braces and other dental corrections, as well as frequent visits to the doctor due to general illness, such as flu, colds, and other symptoms of lowered immunity. As Dr. Price noted in Nutrition and Physical Degeneration, it only takes one generation of men and women who regularly displaced their native foods with processed foods to give birth to children displaying physical irregularities and exhibiting lowered immunity to disease. These deteriorations are now commonly observed in modernized societies, like the United States, where a large proportion of the foods eaten are processed and devitalized.

Comparing American eating and disease patterns in 1900 to those in 2000, one can find several significant changes that have taken place over the last century. In 1900, Americans ate mostly whole foods, although substantial amounts of processed foods were eaten as well. The whole foods eaten by turn-of-the-century Americans included untrimmed meats from pasture-fed animals, fresh vegetables and fruits, grains, and fats like butter, lard, and coconut oil. Of course, this diet differs significantly from the foods Americans eat today: vegetable oils, refined and “enriched” grains, simple starches, sugar, and factory-reared grain-fed meats (in a few words: fast food). Table 1 provides an overview of the changes in American disease patterns before (1900) and after (2000) these processed foods fully crept into the food supply.

Table 1. Leading Causes of Death in 1900 & 2000*

1900_________________% Total_______2000__________________% Total
Tuberculosis.......................11.3...........Diseases of Heart.................31.4
Pneumonia.........................10.2...........Cancer .................................23.3
Diarrheal Diseases..............8.1............Stroke...................................6.9

Bronchitis............................2.6...........Kidney Diseases....................1.0
Diphtheria...........................2.3...........Liver Disease & cirrhosis..........1.0
*Adapted from Food Politics (Nestle 2002, 32)

In Table 1, it can be seen that the shift in American health over the last century has been one of major transition. In 1900, many deaths were due to infectious diseases or injury (6 of 10). This was an era when hygiene was not fully understood and such untimely deaths were commonplace. Heart disease and cancer -- the diseases of modern man -- are seen occurring in moderate percentages during this time. Flash forward to 2000, following many years of processed food consumption, and a very different picture is painted. Almost all of the top diseases (8 of 10) causing death at the time of the millennium are chronic degenerative conditions. The numbers for heart disease and cancer top the list, increasing by four and six times respectively compared to 1900.

The drastic changes in American disease patterns require a broad perspective to fully comprehend. As stated before, in addition to dietary changes, many environmental changes (crowded living conditions and an inadequate food supply) no doubt had a prime role to play in the shift in health that took place over the last hundred or so years. This is one reason why the average lifespan in the United States in 1900 is commonly believed to be far less than it is today. The average lifespan data during this time is also influenced by untimely deaths, such as infectious disease, injury, lack of food, and miscarriages.

Storm & Family: Degenerating Raw Vegans

While individual dietary experimentation can be fascinating, far more valuable information can be gained by observing entire groups of people on certain diets. Weston A. Price's studies are a good example of this, as each unique primitive group he came across displayed varying levels of health on varying diets. What they had in common was beautiful cavity-free teeth and freedom from degenerative disease. All were healthy and vibrant beyond a modern person's wildest dreams. All included animal foods in their diet.

With this in the back of my mind, a friend of mine informed me of a family of 100% raw-food vegans. She handed me a DVD of the family that endorsed their diet and themselves as the ultimate way to optimal wellness. She simply said to me, "I think you'll find this very interesting."

The idea in and of itself was intriguing: an entire family on a raw vegan diet. What did they eat? Were the parents healthy? Were the kids healthy? What were their temperaments like? I was excited to observe the family with these questions in mind.

Here's a decription of the family from their website:

Storm has been eating a raw-vegan diet of fruits, vegetables, nuts and seeds in their natural unheated state for over 30 years and is known for his body builder's physique. At 60 he looks far younger than his years. Jinjee started eating a raw diet 15 years ago. Her before and afters show her weight loss transformation. Our family is 100% raw-vegan and thriving! On this site we share our photos and stories, photos of the kids growing up raw, and videos of raw vegan cuisine being prepared.

Watching the DVD, it's clear that this is a family on a mission to be the healthiest people they can possibly be. Storm, the husband and father, is the most enthusiastic of the bunch, sharing his reasoning behind the "Garden Diet" (as he calls it) and stories about improved health in his family and others who have experimented with this way of eating. His physique is quite impressive for a raw vegan, although nothing close to some of the omnivorisitic hunter-gatherers I've seen. Over the years he'd eaten higher-fat and protein versions of the raw diet -- mostly nuts and seeds -- which seemed to be best years for him in terms of building muscle and being fit. Slowly he transitioned to a more low-calorie raw vegan diet, and now he drinks mostly fresh orange juice for his calories. A low-protein, low-fat, high-sugar diet. Whoa, dude.

Here are a few pictures of Storm over the years.

It's pretty easy to see that his transition from nuts to orange juice isn't helping him much. To be fair, he is 60-years-old now. But this ripped, omnivoristic Austrailian Aborigine (below middle -- not a raw vegan) amidst some other phenomenal physical specimens from his tribe looks to be about the same age or maybe older, and time doesn't seem to be hurting him much:

Of course, there's more to a person than their physical form. In addition to appearance, Weston Price also noted the generous, vibrant, and uplifting nature of the healthy primitives. So I kept an eye out for the overall temperament of the raw vegan family members while watching the film. In certain segments, Storm can be seen philosophizing about the raw lifestyle in a very solemn, kind of soft, muted tone. His eyes look relaxed and sedated. Other scenes find Storm all fired up and ranting like a madman with his eyes bugging out all over the place. There seemed to be some definite blood sugar swings going on, which would make sense since the man was living on orange juice during the making of the film. Lacking a proper balance of amino acids, fats, and b-vitamins -- not to mention a complete absence of fat-soluble vitamins -- Storm appears to be unstable and obsessive. Someone get this man some fatty meat!

Storm's wife, Jinjee, makes several appearances on the DVD, endorsing the raw vegan way of life as whole-heartedly as her husband. Yet Jinjee expresses difficulty in sticking to the diet. She describes periods where she reverted back to cooked foods, but she "knows" raw is the ultimate path to unimaginable health and energy -- if she could only stick to it for life! It's evident that she's torn between listening to her body -- which obviously is craving cooked foods -- and adhering to the arbitrary law of raw. Her pregnancies were either mostly raw or 100% raw, as she explains in the film. Video clips are shown of her pregnancies with each child, and it's a little disturbing how skinny she is for a pregnant woman (see photos).

This brings us to the most fascinating portion of the film: the children. In Weston Price's studies of primitive populations, he discovered that adults suffered suboptimal health when abandoning their traditional diet for one rich in industrialized foods. The children of those adults then grew up with lowered immunity and physical degeneration. We'll get to the raw vegan kids shortly, but for now let's remind ourselves what a healthy traditional child (left) looks like compared to an unhealthy modernized child (right), according to Price:

Notice the round face, prominent cheek bones, wide nostrils, square jaw, and broad dental arch of the child on the left. Now observe the narrow face, sagging cheeks, pinched nostrils, weak jaw, and dental deformities of the child on the right. The child on the left was raised on nutrient-dense food (including animal foods high in vitamins and minerals), while the child on the right grew up eating processed foods like white flour and sugar.

Now that we've been refreshed as to what a healthy, properly-developed child on a traditonal diet actually looks like, take a look at the kids who Storm and Jinjee raised raw vegan (see photos).

Observe the narrow faces, weak jaws, pinched nostrils, and sagging cheeks of the raw vegan children. Like every modern child raised on a deficient diet, these children exhibit facial and dental deformities. The raw vegan diet -- though consisting of primarily whole foods in their "natural, unheated state" -- has not rescued them from the classic manifestations of poor physical development.

The theory of raw veganism is steeped in fanciful and delusional thinking. There has never been a group of human beings in the entire evolution of our species that were 100% raw vegans -- or even vegan for that matter. During Price's travels he was always on the lookout for a primitive population that subsisted solely off of vegetable foods. He never found one. Not only did every group utilize animal foods, they also made great efforts to obtain these foods and held them in very high regard -- particularly for child-rearing. Anthropologists and archaeologists have determined that meat and animal fat consumption (in some cases full-on carnivory) have been a mainstay in the human diet for several million years. Today, healthy traditional cultures all over the world eat cooked plant and animal foods and stay healthy from generation to generation.

Those that believe raw veganism is the ultimate path to wellness -- as Storm and his family do -- fail to take note of these facts and completely disregard hundreds of thousands of years of time-tested human foodways. We were left with the knowledge of proper diet by our ancestors -- perhaps we will only attain optimal health by returning to those food traditions of the past.
