What evidence is > their that humans are carnivores rather than omnivores? Not carnivores, necessarily, but there's evidence that we evolved on a meat-heavy diet virtually devoid of grains, beans, and other concentrated carb foods. An article in The American Journal of Clinical Nutrition in March, 2000, reported on a multi-university, multi-national study of hunter-gatherer diets, both from paleoanthropological evidence, and study of the few remaining hunter-gatherer groups, and concluded that hunter-gatherers generally get over half their calories from animal foods, with the rest coming primarily from vegetables. It specifically said that "protein was elevated at the expense of carbohydrates." -- Dana Carpender
