This reminds me of a UK TV-show I saw (Supersize vs Superskinny). In this one episode there was a very obese woman who was eating at a "soul food" buffet with her family, and after helping herself to the third or fourth gigantic portion of crappy food, she got a comment from her family for using too much salt!. After all, salt is unhealthy... (They didn't even seem to notice the fact that she ate 3-4 times the normal serving size in food). It was like they were thinking "oh, if you would only stop having so much salt on your food you would be thin and healthy in no time."
Sometimes, I feels like people apply the same logic to gluten/gluten free food.
