* Historically, oats were not recommended because it was thought that avenin (the storage protein found in oats) was also toxic to gluten-intolerant individuals. However, recent research in Europe and the US has described that oats are well-tolerated by most children and adults when consumed in moderation and do not contribute to abdominal symptoms, nor prevent intestinal healing. PLEASE NOTE: regular, commercially available oats are frequently contaminated with wheat or barley. However, “pure, uncontaminated” oats have recently become available from several companies in the US and Canada. These companies’ process oats in dedicated facilities and their oats are tested for purity. Pure, uncontaminated oats can be consumed safely in quantities < 1 cup per day. It is important that you talk to your physician and your registered dietitian prior to starting oats.
