It may be a well-worn saying, but scientific data backs it up: You are what you eat. And not only that: You are what your earliest ancestors ate. In short, the story of humanity is inextricably linked to the foods we eat. Award-winning professor Alyssa Crittenden, Ph.D., provides a research-based approach to the history and science of the human diet, taking you far beyond the supermarket and laboratory. Understand our current — and future — relationship with food by looking back in time to the roots of food and food culture, and its intersection with science.
