Greg & Liz welcome back Dr. Michael Greger, a physician, author, and director of Public Health & Animal Agriculture at the Humane Society of the United States. Greger talks about the latest research which reveals the health benefits of a plant based diet, including possible reversal of slow-growing early-stage cancers such as testicular cancer. He also talks about foods that have been shown to extend life, and why you have to follow the evidence when it comes to conflicting claims about healthy diets. www.nutritionfacts.org.
