Last Thursday Paleo promoter Chris Kresser went head-to-head against Vegan advocate Dr. Joel Kahn - it was a 3.5 hour long debate (and they have it all on video and audio file if you want to watch or listen)! Their goal was to clear up the confusion of which diet is the "best" diet.
I listened to it and I have to say Chris was the clear winner, though Dr. Kahn had some really good points.
Chris created a Why Eating Meat Is Good for You “cornerstone page” with a link to the replay of the show, a summary of his key arguments, and links to relevant new and existing articles, as well as links to studies categorized by topic.
This is without a doubt the single most comprehensive resource he's ever created to answer the question: “Should meat and other animal foods be part of the diet?”
