Celiac.com 03/26/2008 - According to the results of a recent study, adults with diet-treated celiac disease show no elevation in anti-avenin IgA by oats. Celiac disease is effectively treated with a gluten-free diet that is free of wheat, rye, barley and related grains. While it is well known that wheat, rye and barley trigger the disease, for decades there has been controversy about the safety of oats.

Recent evidence from a number of studies has supported the idea that oats are safe for people with celiac disease. In several countries, oats are now on the list of safe foods for people with celiac disease. The studies on oats and celiac disease have had various designs, but most have been small, and often with high patient drop-out rates. To date, there has only been a single randomized and double-blinded study measuring the effects of oats on celiac patients. The studies have been nearly unanimous in concluding that consumption of oats is safe to celiac disease patients.

Most of these clinical studies have assessed blood histology in reaction to oats, or measured normalization after patients had been diagnosed with celiac disease and were already following gluten-free diets. Three large studies from Finland have investigated the effect of dietary oats and their influence on antibody levels to wheat gluten and to tissue transglutaminase. Previous studies have shown that people with untreated celiac disease show elevated IgA antibodies in reaction oat
