<<Disclaimer: Verify this information before applying it to your situation.>> In a previous post I made a comment about vinegar, which seems to have caused some misunderstanding. I said that my husband understands now why I react to it. I did not mean to say that I react to all vinegars. I also didn't mean to say that vinegar contains gluten. However, the vinegars that are made from gluten grains do cause me, and many other celiacs to have a celiac type of response. However, "scientifically speaking" there should be no gluten in vinegar, even those made from wheat. Again, I better explain "celiac-type response". I am not talking about intestinal damage which, in my understanding, is only discernable over time. I am talking about an immediate immune system response causing digestive symptoms and in my case, severe weakness. Others on this list have mentioned vomiting, muscle aches, etc. as symptoms they encounter after accidental ingestion of gluten. Someone suggested to me privately, that my post and others like it are leading people to believe that they will sustain intestinal damage if they eat vinegar. The same guy also seems to consider intestinal damage to be the only true celiac symptom. (Since it is the one common to us all.) I do not mean to say that vinegar causes intestinal damage, just that it MAY cause some of the other symptoms. (I honestly don't know about intestinal damage). I think the celiac FAQ's for this list say that some celiacs have trouble with vinegar, and some don't. And they recommend avoiding vinegar only if you react to it. (Hopefully I remember correctly!) This would be my suggestion as well. Last of all, to answer a recent question, apple cider vinegar and wine vinegar should be safe for anyone. I hope this helps clear things up for someone. Thanks to those who sent me encouraging responses to my biopsy post! Janet Olympia, WA
