That surely does not jibe with the good feelings I get from eating venison. Or fish.
Fact is, we humans are omnivores and have developed for eons by including meat in our diets. Humans are quite adaptive, and there are instances of peoples living primarily on fruits just as there are instances of people living primarily on vegetable and instances of peoples living primarily on meats who fare reasonable well - but we are adapted to take advantage of a very wide range of nutrients as well as healthy fats, some of which are found almost exclusively in meats.
