I'm making the film <a href="http://FoodLies.org" rel="nofollow">http://FoodLies.org</a> and have interviewed a lot of top researchers, doctors, and though leaders of all aspects of nutrition and even the environmental impact of eating different foods. I picked the most important topics and people and got them to do an audio interview with me as well. I modeled it after the awesome "How to Start a Startup" class with Sam Altman.
This is a terrific podcast. Brian is an obviously well-read and inquisitive host. He asks great questions, interviews intelligent guests, and makes all of this complex information very accessible. Highly recommended.
