<<Disclaimer: Verify this information before applying it to your situation.>> About my son: he is 3, in diapers, and partially verbal. He is celiac and autistic, and is gluten and casein free. Question: How long should a gluten reaction last? Last month he had a reaction that lasted a few weeks, after having eaten cookies that contained gluten, or something that upset his tummy, for about a week. This month, he is having another reaction, after about a week of ALMOST normal-for-him bm's (which are a couple of mushy, pasty, non-formed, light-colored stools per day), after eating suspect cookies for only two days. His reaction, both times has been many ( I stopped counting at 5) large-volume, noisily-expelled, horrific smelling, pure liquid, DARK, stools, which often contain bits of undigested food, per day, with bloating. I can tell when he is about to have a movement because it is the only time of the day when his pants don't fall down without a belt (he is really thin) - the bloating is enough to keep his pants up. Immediately after having the movement, his pants start to fall down again. Another question: How can you differentiate btwn a gluten reaction and another food intolerance? My son has had classic gluten reactions both this month and last month. Last month it was after I made cookies with quinoa flakes that I got from a bulk bin at Wild Oats, and this month after using amaranth flour in cookies that I got form a bulk bin at Wild Oats. Yes, I know bulk bins are bad, and I won't use them again, because it is possible that this is cross-contamination from the bins or scoops. And I know that the CSA is extremely conservative in warning away celiacs from amaranth and quinoa. But is it possible that more sensitive celiacs can't handle these grains as well, perhaps the protein in them is similar to that of wheat gliadin? I'd like to hear from any celiacs out there that also have intolerances to either of these grains, in order to ascertain if the reaction is the same as the reaction to gluten. Thanks! Catherine in AZ
