Celiac.com 03/17/2000 - Finish researchers report that people with celiac disease who eat oats show no adverse autoantibody or intraepithelial lymphocyte level effects. According to Dr. M. I. J. Uusitupa (University of Kuopio), and colleagues: Wheat, rye, and barley have harmful effects on the small intestinal mucosa of patients with coeliac disease, whereas maize and rice are harmless...(H)owever, the place of oats in the coeliac diet has been debated. The researchers studied two groups: 40 adults with newly diagnosed celiac disease and 52 adults whose celiac disease was in remission. The people in both groups were randomized to either a conventional gluten-free diet, or a gluten-free diet that also included oats. Both groups were monitored for autoantibodies and intraepithelial lymphocytes over a 6- or 12-month period. In the patients with newly diagnosed celiac disease the disappearance rates of antireticulin antibodies, antigliadin antibodies, and intraepithelial lymphocytes were the same, regardless of their diet. Likewise the people with celiac disease that was in remission had similar antibody and intraepithelial lymphocyte levels between both dietary groups. According to the researchers: These results strengthen the view that adult patients with coeliac disease can consume moderate amounts of oats without adverse immunological effects. The researchers also note that: more clinical studies are needed to ensure the safety of oats when consumed permanently in a coeliac diet as well as to determine the effect of larger amounts of oats.
