Is gluten-free eating—outside of the realm of the rare autoimmune condition celiac disease—just a fad? Or is it the answer to millions of cases of undiagnosed gluten sensitivity?

This discussion, hosted by Tom Ashbrook, includes perspectives from Dr. James Hamblin; Dr. Peter Green, director of the Celiac Disease Center at Columbia University and author of Celiac Disease: A Hidden Epidemic; Mieke Johnson, proprietor at Tula Gluten-Free Bakery Cafe; and Dr. David Perlmutter, neurologist and author of Grain Brain: The Surprising Truth About Wheat, Carbs and Sugar, Your Brain’s Silent Killers.

The discussion is a response to Hamblin's December Atlantic piece "This Is Your Brain on Gluten."
