This chart presents another way of looking into the diet of our evolutionary ancestors by comparing one researcher's understanding of the Paleolithic diet with the diet of the diet of 20th century Americans. As I pointed out in this post, there's still considerable debate about the merits of a Paleolithic diet and its implications in the modern diseases of affluence.
Is the diet of our evolutionary ancestors a good place to start looking for a model diet and lifestyle? Weigh in on the discussion here.
