I'm just wondering: where do you think Paleolithic man (and even more primitive ancestors) get all these carbs? They certainly didn't eat grains or other cultivated crops. I imagine they got most carbs from fruit, but away from the tropics fruit is only seasonally available. The rest of the diet was veggies, mammals, birds, insects, fish, crustaceans, & mollusks. I think we are not adapted well to the modern high-carb diet derived from cereal grains.
Ask an aborigine to point at food, he points at an animal.
Ask him about plants, and he’ll reply that that is what food eats.
LOL
Paleolithic man might have eaten fruits and berries, but that was generally subsistence level eating. Their preference was for meat.
For example, the Gwi people of Southern Africa derive only 25% of their calories from meat sources.
Ever heard of tubers?
