Your dog won't protect your kid from type 1 diabetes. This goes against the theory (which I tend to agree with) that "eating dirt protects us from autoimmune diseases."
Gluten-free diets don't appear to cut heart disease risk. Let me get this straight: celiac disease affects (thankfully) a very small fraction of people. For the rest of us, going gluten-free may increase our risk of diabetes and doesn't seem to have other beneficial effects. So why are so many people going gluten-free?
