If we were all eating the corn that God put on this earth before man improved on it we wouldnt have the obesity problem every one keeps talking about. ;-)
Because corn was a grass and not real nutritious . I’m sure that before the Europeans got here the natives selectively nurtured the better strains for a better food source. Through centuries of selective genetic modification it has become a staple for millions if not billions of people. Corn before man started modifying it would not have caused much of an obesity problem.
