They tend to have yearly summits on different health topics. Each of them is capturing a niche in the new functional medicine frontier and the summits are chock full of interesting information and you can listen for free for 24 hours and can then purchase the whole series usually for about $97. It’s a model many of them use. Dr. Michael Greger is different. He has a video blog where he discusses medical studies on different conditions and is a complete advocate of plant-based eating. He gives all the proceeds of his books to charity. Mark Hyman is more middle-of-the-road. He heads up some functional medicine division at the Cleveland Clinic.

I found out about all these doctors through John and Ocean Robbins’ Food Revolution Network, which has another very substantive blog about the nutritional value and environmental impact of all kinds of foods. Also plant-based. He’s not a doctor, but a master researcher on nutrition, and a humorous, entertaining writer. The father, John Robbins, wrote a bestseller in the 90’s called Diet for a New America. He was a principal heir to the Baskin and Robbins ice cream fortune and went in a radically different direction. So much good information on staying healthy out there!
