> all the things you listed are only eaten with the modern, unnatural manmade vegetable/grain counterparts, the wild ancestors of what you listed are either extremely scarce, as in humans never naturally subsisted off of them, or were simply indigestible. humans have been consuming plant seeds for over 200,000 years. even neanderthal was eating grains before they went extinct. we have been cultivating them for well over 10,000 years. tribes that have existed since before the cradle of civilization was born in the mesopotamian region have been cultivating plants both in farms and in natural situ environments. the ojibwa would collect barrels worth of wild rice from naturally growing wild rice plants and they would intentionally cast some rice into the water to ensure a strong crop in the future. natives all over the americans ate tubers, potatoes, ancient corns, beans, squash, etc. long before any industrialism or advanced civilization was formed. trying to classy human behavior as unnatural is retarded. animals do what they can to get nutrients. humans would go to new lands and find ways to consume every little thing they possible can, because food is survival. saying they can't eat grains is like saying they can't eat berries. it's gathering, retard.
