<<Disclaimer: Verify this information before applying it to your situation.>> In terms of the symptoms thing, again because I only logged on recently, I don't know what product exactly Don Wiss had a problem with. I know my mom and I (she is also a celiac) have to be careful buying tortillas because of the sulfites that Kemp mentioned. I would be interested to here if others have had problems with sulfites. It is much worse for my mother than me. Both of us experience a swelling in our fingers and kind of a "black cloud" around the head feeling. My mother's swelling is so extreme the skin often breaks and bleeds, and sometimes causes her to feel that she can't function. This happens when she drinks white wine (all wines naturally contain sulfites, but white wines contain addition artificially added sulfites). Most recently we experienced it when there was sulfites in a balsamic vinegar, which is usually safe. That was a long addendum to a short question, so just in case you forgot, the basic question was: Has anyone else had a problem with sulfites? Sincerely, Kristine P.S. Which product was it that Don Wiss reacted to anyway?
