Thanks for all your thoughts on this. I'm not willing to try an unproven (to me) treatment either, but it does make me wonder! We're eating very well but do sometimes miss the spontaneity of being able to grab a bite to eat somewhere if we're out longer than planned (and therefore without a cooler of food in the trunk!).

I know I've read (somewhere - here?) that people with gluten sensitivity often find other food intolerances after being gf for a while (this seems to be true with my son), and that oftentimes they can resume eating those "other" foods after abstaining from them for months. It make me wonder if some of these "treatments" speed up that process. But alas, how to tell which foods are health-threatening and which ones aren't?!
