I don't know a lot about gluten free diets, but apparently for all but a small percentage of humans, they're completely useless.
If you have Celiac, this obviously doesn't apply to you. Don't eat gluten. But if you don't have Celiac—and that's 99% of the human population, mind you—there's no reason to be gluten free. You're wasting your time. Even the scientist who started this gluten free craze thinks it's useless to be gluten free. Seriously. People, the father of gluten free think it's bullshit. LinkBottom line, for most people, their reaction to gluten is the nocebo effect. It's all in their minds.
