Since I've been reading up on that formerly forbidden subject of evolution, it occurs to me that my ideas on diet have been wrong. Too.
Here's my idea: All early human societies were of the hunter-gatherer type. Now this probably means they ate a lot of meat. According to 'The 3rd Chimpanzee' by Jared Diamond, the early people who came to N and S America decimated the animal population by 73% and 78% respectively because of over-hunting. That's a lot of meat-eating!
Now, deducing our earliest ancestors were of the eat-a-lot-of-meat types, is that why the 'high-protein' diets of today work so well?
Even when our ancestors were farmers, they still kept a lot of livestock for eating.
So, is being a vegetarian (which I was--right before I got cancer!!) that natural for us if we evolved from humans that were heavy meat-eaters. They were also gatherers, but maybe meat was their mainstay. How much could you gather in the winter?
Any rebuttals or comments?
