<<Disclaimer: Verify this information before applying it to your situation.>> If you're into this kind of stuff. Here's an article that explains zonulin better than any other I've seen. It's called "Loosen Up" by John Travis and is found in Science News On Line. It summarizes how zonulin was discovered which really helps the reader understand what it is and how it is related to celiac disease. As many are aware by now, Alba is doing human trials on a drug that will inhibit zonulin's activity in the gut. I don't yet see how that's really going to help us celiacs, but who knows? I'm trying to remain optimistic. http://sciencenews.org/articles/20000422/bob8.asp Valerie in Tacoma *Support summarization of posts, reply to the SENDER not the CELIAC List*
