The reason we're eating wheat even though we're not made for it is because we could support larger populations on that versus hunting and gathering. Farming societies eventually won, even though hunters and gatherers were more healthy, because farming societies have a food surplus (which it can store), and can then afford to wage war and expand. If you look at skeletons from before and after farming, you see that hunter and gatherers were taller, had bigger brains than we have today, and were overall healthier.
