"Rice itself is gluten free (it does contain rice gluten, but it is NOT the gluten that triggers the autoimmune response of a celiac, btw.) The problem with white rice is that it is enriched, which means that the rice is sprayed with a vitamin enriched coating. Most of the big (e.g. Uncle Ben's, Mahatma) manufacturers use a corn based starch to get the coating to stick to the rice but that is no gaurantee that they ALL use a gluten free coating, so you have to go brand by brand to determine what is safe to eat and what is not."
