<<Disclaimer: Verify this information before applying it to your situation.>> I've been following this list for several months after discovering it while searching the web for possible causes of a chronic sinus infection. I've learned a lot about celiac disease on this list and I don't think that is what I have. I've been skin-tested for allergies and all were negative. Nasal smear showed tones of bacteria, and xrays confirmed extensive inflamataion. I have been plagued with ongoning sneezing and runny nose for at least 5 years along with a chronic loose stool (not diarrhea.) I'd be interested to hear from anyone who has found relief from sinus problems after going GF. Thanks all, Don Hildebrand Eugene, OR
