Sweet potatoes are a separate species (Ipomoea batatas) related to morning glory; both 'sweet potatoes' and yams are gluten-free. The Celiac Disease Foundation, FDA, and major celiac organizations confirm potatoes' gluten-free status. People with celiac disease can safely eat potatoes prepared in gluten-free ways.
