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."
Shattering The Meat Myth: Humans Are Natural Vegetarians
That's just off the charts stupid. Of course we can rip through and chew meat. We are omnivores not herbivorous. Billions of people have proven it.
Ding dong was comparing human teeth to wolves, which are carnivores. And just because we can eat meat, it doesn't mean we should. As I already pointed out, our intestines are long, while a carnivores intestines are short and can digest meat much faster. Obviously, you didn't read the entire link.
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.
