On this week's episode, Moran sits down with Dr. William Li, an internal medicine doctor, vascular biologist, and author of the book "Eat to Beat Disease." Dr Li always had an interest in food and diet lifestyles since he was young, and he studied the links between food, culture and the health of communities around the world for years. Dr Li looked to blood vessels to find common denominators within different diseases and has been involved in 41 FDA-approved medications for disease treatment from his studies.

The medical director for the Angiogenesis Foundation, Dr Li explains the way our body grows blood vessels, a central tenant to health. His research has shown that certain foods help our body overgrow blood vessels that could potentially cause diseases like cancer. Dr Li applies the "Food as Medicine Research" method to his work, talking  about foods that activate our health defenses, and what to add to our body to build ourselves up. His personal mantra is to "love your food & love your health."

In this in-depth conversation, Dr Li discusses fasting & its relation to his research, his "grand slam" foods, what helps treat disease along with prevention, and the power of fiber.
