A whole-foods, Starch-Smart® diet supplies more than enough protein to meet our daily requirements. "Protein Overload" is an excellent article written by Dr. John McDougall. He explains that "A little protein is good, but more is not better. Protein consumed beyond our needs is a health hazard as devastating as excess dietary fat and cholesterol. Unfortunately, almost everyone on the typical Western diet is overburdened with protein to the point of physical collapse. The public has almost no awareness of problems of protein overload, but scientists have known about the damaging effects of excess protein for more than a century."
