Have you ever carefully examined how hard it is for a vegetarian, or especially a vegan, to get all the right nutrients?
I got news for you, primeval man did not have the discretionary ability we have today in our food.
Protein is an excellent example. The primary sources for vegans are nuts/seeds, and legumes. If you can't cook, it's very hard to eat legumes- have you ever tried eating a raw pinto bean? They are literally hard as rocks. Plus they cannot be found across the globe. Nuts and seeds are very seasonal, leaving man high and dry in certain seasons, and it's much much more of a challenge to harvest 6+ oz of nuts every day than it is to buy a jar of them at the store.
