<<Disclaimer: Verify this information before applying it to your situation.>> I just read the rules on summarizing responses, so here it goes: Corn and rice have gluten but not gliadin. Gliadin is the amino acid which is found in the gluten protein of wheat, rye, oats (pending) and barley that is destroying our microvilli. Corn is hard to digest for some, but, unless there is any allergic reaction, it is ok to eat. I say pending with oats because there is still research being done to determine if they cause damage to our villi or not. But until the research is conclusive it is important to stay away from oats. Thanks again everyone! God bless, Elizabeth
