Billy Bob Thornton stopped eating dairy after discovering it was causing health problems. But is that a healthy decision?

Dr. Neal Barnard joins Chuck Carroll to separate fact from fiction.

Could milk and cheese be behind symptoms such as bloating, stomach pain, fatigue, skin issues, congestion, brain fog, or feeling sick after eating?

Dr. Barnard explains the difference between a true dairy allergy, lactose intolerance, and dairy sensitivity. He also discusses what PCRM research shows about dairy, saturated fat, cancer risk, heart health, and the health benefits of choosing dairy alternatives.

Then we look at Thornton's wheat sensitivity. What is a true wheat allergy? How is it different from celiac disease or gluten sensitivity? And when should someone get tested before removing gluten from their diet?

Plus, Billy Bob Thornton also said he eats for his AB-negative blood type. Dr. Barnard explains what the research actually says about blood-type diets, and whether blood type should determine what you eat.
