EVIDENCE-BASED ANSWER
Are Oats Gluten-Free for Celiac Disease?
Pure oats do not naturally contain wheat, barley, or rye gluten, but ordinary oats are frequently cross-contacted during growing and processing. People with celiac disease should choose oats specifically labeled gluten-free. A small minority may react to avenin, the oat protein, so introduce oats with clinical guidance if symptoms or lab results remain abnormal.
