Chocolate, Cheese, Meat, and Sugar -- Physically Addictive

Neal Barnard MD discusses the science behind food additions. Willpower is not to blame: chocolate, cheese, meat, and sugar release opiate-like substances. Dr. Barnard also discusses how industry, aided by government, exploits these natural cravings, pushing us to eat more and more unhealthy foods. A plant-based diet is the solution to avoid many of these problems. Neal Barnard is the founder of the Physicians Committee for Responsible Medicine (PCRM).
