In search of the perfect human diet, Victoria Boutenko compares the standard American diet with the diet of wild chimpanzees. Chimpanzees share an estimated 99.4% of genes with humans, but their diet is dramatically different from ours. The most glaring difference is that chimpanzees consume significantly more green leaves than humans. Victoria developed a series of greens smoothies that enable anyone to consume the necessary amount of greens in a very palatable way.
