Milwaukee heart doctor William Davis is convinced the single biggest threat to health in North America is wheat. Or at least the modern super-hybrid “dwarf” kind found in all manner of processed foods. As a cardiologist, Dr. Davis, saw radical results in his patients when they cut our wheat-based foods and he synthesized it into his New York Times bestselling book Wheat Belly. Pushing up against half a century of received nutritional wisdom has meant some controversy around the book, which blames wheat for a host of physical problems including the striking rise in obesity and Type II diabetes in North America since the 1980s. In the video below we discuss what happens to our bodies and brains when we eat (modern) wheat, why wheat is in just about every processed food there is and the surprising reason that Dr. Davis became interested in the connection between wheat and health to begin with.
