Gluten Free Since Sept...but ... Still Sufferring in Food Intolerance & Leaky Gut Posted January 17, 2013 · Report to Admin That is what happened to me. In my case, I traced it to corn intolerance also. I found going gluten-free was easy, this is the best day/time in the world to do that, as more companies are careful to label things gluten-free. Its not the same with corn, there are many derivitves of it, hiding under other names, and it is used in/on nearly everything. Going on a clean unprocessed diet is not much help, because, for instance, fresh produce is sprayed with corn, meat processors use corn based cleaners. Good luck finding your answer. You might want to look at corn next. Celiac and corn intolerance seem to go hand in hand.
