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

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.

Stay tuned for the next post titled, "Were Early Americans Really Living Shorter Lives?"

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.

Can High-Carb, Low-Fat Be Healthy?

Compared to us moderns, many paleolithic and neolithic cultures who ate high-carbohydrate, starchy diets exhibited good health -- full sets of teeth and nicely developed noggins along with an absence of degenerative disease. A few of these cultures include the Kitavans (tubers, fruit, coconuts, & fish), the Kuna (plantain, yucca, kidney beans, fruit, & wild game/fish), and the traditional Peruvians (potatoes, quinoa, & guinea pigs -- seen in Nutrition & Physical Degeneration by Weston A. Price). As somebody who has adhered to a carbohydrate model (ala Taubes) in explaining present-day diseases and ill health, the fact that human beings can thrive on high-carbohydrate diets fascinates me. So let's explore this!

We'll begin by examining some of the obsevations of T.L. Cleave, who wrote an important book called The Saccharine Disease. In this book, Cleave notes that the rural Zulu of Africa (in the 1950s) were in good health on a diet comprised of 90% carbohydrate calories (Matt Stone recently blogged about this subject and sparked my interest). In contrast, the urban Zulu ate less carbohydrates (81%), yet had more diseases than the rural Zulu. Cleave concluded that the amount of carbs being eaten by the two groups didn't matter so much as the types of carbs. This seemed to make all the difference: the rural population ate maize and root vegetables while the city-dwellers consumed refined, industrialized carbs, such as sugar and white flour. Through observations such as this, T.L. Cleave, like Weston A. Price before him, showed quite convincingly that refined foods are the cause of modern degenerative diseases.

But this isn't the entire story. If we are to think critically about Cleave's theory, we find that he oversimplified things a bit too much, lumping all detrimental foods into one category: refined carbohydrates. What this implies is that a person can consume all the whole grains, fruits, and potatoes he or she wants without experiencing the "diseases of civilization": diabetes, obesity, dental caries and crooked teeth, gastrointestinal ailments, heart disease, etc. As long we avoid sugar and refined grains, we'll live in good health, just as the rural Zulu did. Hmmm ... maybe.

While Cleave may or may not have been right about the general nature of refined carbs and their effects on human health, one glaring hitch in his theory is the fact that he overlooked something very simple: the chemical differences in carbohydrate foods and how these differences may be major factors in present-day diseases. In other words, it's not as simple as whole foods vs. refined foods -- it's also a matter of the qualities of the foods. To illustrate this, let's evaluate two of the evils that Cleave proclaims to be the cause of modern man's health demise. On one hand we have white flour: a starch -- also known chemically as a polysaccharide -- which is broken down to glucose in the body. Sugar, on the other hand, is a disaccharide with a significant difference: it's composed of glucose and fructose, which the body handles quite differently than it does starch. Gary Taubes, author of Good Calories, Bad Calories, explains sugar's disaccharide nature in the body:

"The fructose will stimulate the liver to produce triglycerides, while the glucose will stimulate insulin secretion. And the glucose-induced insulin response in turn will prompt the liver to secrete even more triglycerides than it would from fructose alone, while the insulin will also elevate blood pressure apart from the effect of fructose." (p. 201)

The effects of fructose and glucose on the formation of AGEs (junk proteins in the body implicated in age-related chronic diseases) is also interesting. Taubes writes:

"Glucose [alone] ... is the least reactive of all sugars, the one least likely to attach itself without an enzyme to a nearby protein, which is the first step in the formation of AGEs. As it turns out, however, fructose is significantly more reactive in the bloodstream than glucose, and perhaps ten times more effective than glucose at inducing the cross-linking of proteins that leads to the cellular junk of [AGEs]. Fructose [induced-AGEs] ... seem more resistant to the body's disposal mechanisms than ... glucose. It also increases markedly the oxidation of LDL particles, which appears to be a necessary step in atherosclerosis." (p. 201)


Glucose -- the "least reactive of all sugars" -- appears to be the most ideal carbohydrate to consume if we are to avoid disease. Fructose seems to be the worst. Together, as sugar or honey or high-fructose-corn-syrup -- all glucose/fructose combinations -- they are the worst of the worst. It's kind of like putting Vin Diesel and Chuck Norris in an action flick together. Not good. You know somebody's gonna die.

So perhaps it is sugar (more specifically, fructose) and not refined foods like white flour or white rice (starches) that lead to our modern health ailments. It's hard to say for certain which food caused problems when evaluating primitive cultures as Cleave and Price did because, in every case examined, where there was smoke there was fire: white flour and sugar were being eaten at the same time. Yet, if it were all refined carbohydrates that lead to ill health, then how are we to explain healthy cultures on a diet centered around white rice such as the Japanese and Koreans? These cultures also consume animal foods in the form of fish, beef, and eggs -- all cholesterol-rich foods. Yet they have little heart disease. What's missing, which many industrialized cultures consume plenty of, is excessive sugar and high-fructose corn syrup (particularly in the form of soft drinks). Fructose intake in these countries has been very low traditionally, although it continues to grow from year to year.

I was actually in Seoul, Korea recently and noticed that almost everybody was slim and healthy-looking. The only obese Koreans I observed were a few children here and there. As consumption of soda, candy, and other fructose-sweetened products are increasing, displacing the starch calories in the diet, it appears that nation-wide obesity (and its slew of health complications) is on the rise.

With all of this to consider, we are left with a question: is fructose the culprit in present-day chronic disease? A man by the name of Dr. Richard Johnson theorizes that it is. His research strongly indicates this food as the main player in everything from diabetes to heart disease. The more and more I research it, the more I am convinced of such a theory. The Nutrition & Metabolism Society had this to say in a paper on fructose:

The alarming increase in fructose consumption may be an important contributor to the epidemic of obesity and insulin resistant diabetes in both pediatric and adult populations.

And this (italics mine):

A high flux of fructose to the liver, the main organ capable of metabolizing this simple carbohydrate, disturbs normal hepatic carbohydrate metabolism leading to two major consequences... perturbations in glucose metabolism and glucose uptake pathways, and a significantly enhanced rate of de novo lipogenesis and TG [triglyceride] synthesis, driven by the high flux of glycerol and acyl portions of TG molecules coming from fructose catabolism. These metabolic disturbances appear to underlie the induction of insulin resistance commonly observed with high fructose feeding in both humans and animal models.


What I'm getting at here, in a long-winded, haphazard sort-of-way, is this working theory:

• Fructose in excessive quantities (i.e. standard American diet) is detrimental to human health.
• Starch alone is not detrimental to human health.
• A high-carbohydrate, starch-based diet -- that includes animal proteins & fats -- is a viable diet for long-term health.
• Human beings can thrive on a wide variety of diets -- a high-fructose diet does not seem to be one of them.

All of that being said, there is one important caveat to consider. If a person is already affected by diabetes and/or obesity or some other degenerative condition, a simple reduction in fructose may not provide health improvement. When the metabolism or equilibrium of the body is disturbed in such an unnatural way (theoretically from over-consumption of fructose), starch or any other carbohydrate may exacerbate the condition further. For these kinds of people, a low-carbohydrate diet may be the most therapeutic diet for the long-term.

I'd also like to add that, although fructose -- and not carbohydrates in general -- may be the true instigator in degenerative disease, a high-fat, low-carb diet has advantages that a high-carb diet does not: lipolysis, stable blood sugar, greater satiety, lack of hunger, more "protective" and nutrient-dense foods, and so on.

Not to mention the fact that the more carnivoristic tribes of ancient and contemporary history dispaly greater strength, minimal dental caries, and denser bones compared to agricultural, starch-eating peoples. Here's Dr. Price's observation in Africa:

In contrast with the Masai, the Kikuyu tribe...are charcterized by being primarily an agricultural people... [they] are not as tall as the Masai and physically they are much less rugged... teeth with caries [were] 5.5 percent ... 36.4 percent [of the population]. (pp. 138-139)

Therefore, although it's interesting that human beings can live in good health on a starch-based diet, I'll stick with a low-carb (100 grams or less), diet rich in animal products, thank you!
