Truthological spirit

Before having to face the consequences of our actions, we must consider the optimal way to proceed.  As it pertains to the human diet, this is my definition of Truthology.  It’s a study of what we should be doing – what is in our best interests – to help guide our decision-making process.  That’s not to say we are forbidden from indulging, but we should do so with complete awareness.  Many people go by the notion of “everything in moderation”, especially when it comes to eating, yet do not fully realize what exactly they are doing in moderation.  What are the long-term effects (to you and the world around you) of what you are doing in moderation?  There are many things that I would never choose to do at all, much less “in moderation”.  It’s very important to be aware of the long-term actions we engage in (both good and bad), so that our results live up to our expectations.

Following is a great article written by Kathy Freston, which was published in the “Healthy Living” section of the Huffington Post.  To me, whether you believe this or not, this embodies the spirit of Truthology. 

Shattering The Meat Myth: Humans Are Natural Vegetarians

Going through the comments of some of my recent posts, I noticed the frequently stated notion that eating meat was an essential step in human evolution. While this notion may comfort the meat industry, it’s simply not true, scientifically.

Dr. T. Colin Campbell, professor emeritus at Cornell University and author of The China Study, explains that in fact, we only recently (historically speaking) began eating meat, and that the inclusion of meat in our diet came well after we became who we are today. He explains that “the birth of agriculture only started about 10,000 years ago at a time when it became considerably more convenient to herd animals. This is not nearly as long as the time [that] fashioned our basic biochemical functionality (at least tens of millions of years) and which functionality depends on the nutrient composition of plant-based foods.”

That jibes with what Physicians Committee for Responsible Medicine President Dr. Neal Barnard says in his book, The Power of Your Plate, in which he explains that “early humans had diets very much like other great apes, which is to say a largely plant-based diet, drawing on foods we can pick with our hands. Research suggests that meat-eating probably began by scavenging–eating the leftovers that carnivores had left behind. However, our bodies have never adapted to it. To this day, meat-eaters have a higher incidence of heart disease, cancer, diabetes, and other problems.”

There is no more authoritative source on anthropological issues than paleontologist Dr. Richard Leakey, who explains what anyone who has taken an introductory physiology course might have discerned intuitively–that humans are herbivores. Leakey notes that “[y]ou can’t tear flesh by hand, you can’t tear hide by hand…. We wouldn’t have been able to deal with food source that required those large canines” (although we have teeth that are called “canines,” they bear little resemblance to the canines of carnivores).

In fact, our hands are perfect for grabbing and picking fruits and vegetables. Similarly, like the intestines of other herbivores, ours are very long (carnivores have short intestines so they can quickly get rid of all that rotting flesh they eat).  We don’t have sharp claws to seize and hold down prey.  And most of us (hopefully) lack the instinct that would drive us to chase and then kill animals and devour their raw carcasses. Dr. Milton Mills builds on these points and offers dozens more in his essay, “A Comparative Anatomy of Eating.”

The point is this: Thousands of years ago when we were hunter-gatherers, we may have needed a bit of meat in our diets in times of scarcity, but we don’t need it now.  Says Dr. William C. Roberts, editor of the American Journal of Cardiology, “Although we think we are, and we act as if we are, human beings are not natural carnivores.  When we kill animals to eat them, they end up killing us, because their flesh, which contains cholesterol and saturated fat, was never intended for human beings, who are natural herbivores.”

Sure, most of us are “behavioral omnivores”–that is, we eat meat, so that defines us as omnivorous. But our evolution and physiology are herbivorous, and ample science proves that when we choose to eat meat, that causes problems, from decreased energy and a need for more sleep up to increased risk for obesity, diabetes, heart disease, and cancer.

Old habits die hard, and it’s convenient for people who like to eat meat to think that there is evidence to support their belief that eating meat is “natural” or the cause of our evolution. For many years, I too, clung to the idea that meat and dairy were good for me; I realize now that I was probably comforted to have justification for my continued attachment to the traditions I grew up with.

But in fact top nutritional and anthropological scientists from the most reputable institutions imaginable say categorically that humans are natural herbivores, and that we will be healthier today if we stick with our herbivorous roots. It may be inconvenient, but it alas, it is the truth.
