I'm semi-sensitive to it because one of my kids has been gluten-free for about 3 years. She had digestive problems (bad constipation) which lead to behavior problems (she always felt bad, so she was often moody and unpleasant). Eliminating gluten solved the physical problem, which greatly improved the behavior problem, and we went from something that was a constant source of stress to an afterthought. Sure, there are a bunch of douche-bags who have taken to it like every other fad diet, but Bernie Lincicome can eat a bag of dicks for his dismissive and condescending statement (particularly to open an article, which I'm sure only got worse)
