This article in the November, 2010 "Runner's World" re the GF diet was discovered by your one and only, while I was working out a few minutes ago. Yeah, print magazines! It restates what I and other gluten free epicureanistas have known all along: the GF diet can be healthier mainly because it requires one to go back to the basics -- beans, nuts, fruits and veggies, meat cooked without a lot of additives. But it's not necessarily healthier, per se. See my page, "Gluten Free for a Healthy Weight?" It also affirms that some GF grains -- quinoa, amaranth, and buckwheat -- to name a few, are, indeed, chock full of nutrients, fiber, etc. Please see my blog post (December 10, 2010) about the healthier GF grains: "Amaranth, buckwheat, and quinoa: gluten free grains at the the top of the heap!"
