One Question, Answer all parts. Nutrition class

Discussion Instructions:

Research suggests that our human ancestors consumed a diet higher in animal protein, and much more modest in carbohydrate content than current modern-day recommendations, with the majority of the carbohydrates coming from fruits and vegetables, and no cereal grains. How do ancestral diets compare to modern day diets of competitive athletes? Is it possible for a dietary scheme similar to that described by Lindeberg to sufficiently support high-level athletics, such as elite and Olympic-level performers? Provide a clear, detailed rationale, drawing parallels and contrasts between exercise nutrition needs during both human eras. Include examples where appropriate.
