<<Disclaimer: Verify this information before applying it to your situation.>> Let me start this by saying that I do eat distilled vinegar. Although, being a scientist myself, I agree with Bonnie's view that it is very unlikely to find gluten after the distillation process, I think this calls for a definition of "find". Biological systems provide the most sensitive chemical sensors we know. This is one of the many reasons that biotechnology has become so popular lately. For example, there are companies developing biosensors for monitoring pollution of the air. If an insect can smell one scent molecule in a billion, we cannot offhand deny the possibility that maybe an extremely sensitive Celiac could detect a trace of gluten which would be below the detection limit of chemical analysis. If this is an autoimmune disease, not simple poisoning, the threshold for a reaction could be extremely low. This brings up another interesting point: can we safely conclude that if someone doesn't notice a reaction to vinegar, it is safe for them to eat it? This seems to be the general consensus, but I wonder if it is the right decision. I know that I can eat small amounts of gluten without noticing a reaction. I've had Nacho flavor Dorritos, and only later noticed the wheat in the ingredient list. No reaction, although I am a biopsy confirmed Celiac. Now surely nobody (except for the ignorant doctors we keep reading about) would argue that this means it's okay for me to have a little bit of wheat now and then. But we will classify vinegar, msg and other things as "don't eat if you're very sensitive". I am not arguing that we should all stop eating a food whenever someone reports a reaction. After all, you can have belly aches from a lot of things. But I do worry that because unlike other's bodies, mine doesn't punish me instantly for every gluten mistake, I'm slowly damaging it. Maybe the people with the violent reactions are actually better off, and we should follow their example in thoroughness when it comes to eliminating gluten from our diets. This is a personal decision everyone will have to make for themselves, but we should accept other's choices and take them seriously. I think that despite my worries, I will continue to eat vinegar. I simply can't face another dietary restriction. Sylvia in Ithaca, NY.
