I share Elayne's skepticism of certain absolutist diet trends. I guess I'm specifically responding to the anthropological and anatomic claims of Paleo/Primitive and Veganism. The truth is that diet has always been astonishingly varied. The Inuit might live on whale, the Ancient Chinese on rice and millet; a staple for various primitive tribes was inner tree bark which they pounded into paste. The early Mongols, it is reported, even nourished themselves during thin seasons by drinking not just mare's-milk, but the fresh blood of their living horses.
