“Whether oats should be included in a gluten-free diet has been debated for half a century. In 1995, the largest and most scientifically rigorous study on the safety of oats was published. Investigators concluded that the consumption of oats was safe for adults with celiac disease. Since 1995, several additional studies have been published. Without exception, these investigations found no adverse effects associated with the regular consumption of moderate amounts of oats. However, there are concerns among some authorities on celiac disease that even if oats themselves are safe, they nonetheless may be contaminated with wheat, rye, or barley. Unfortunately, the extent to which contamination of commercial oat products occur is not known. Ideally, if a patient appears likely to use oats, they should be advised to consume only those products tested and found to be free of contamination.”

“Celiac disease is an intolerance to protein fractions in wheat, rye, barley, and possibly oats. When these grains are consumed by a person with celiac disease, they damage the mucosa of the small intestine, which eventually leads to malabsorption of nutrients. Patients are therefore advised to remove these grains from their diet, with lifelong adherence generally suggested. Although many dieticians and physicians consider this dietary prescription to be standard protocol, it is actually quite controversial. Whether oats can safely be consumed by persons with celiac disease has been debated since the gluten-free diet was first advocated more than 40 years ago. Historically, there have been several reasons for this debate, including the difficulty in identifying the precise amino acid sequence in gliadin that is responsible for toxicity; the differences in cereal chemistry between wheat and oats; and the lack of well-designed studies to assess the toxicity of oats. A growing body of evidence now suggests that moderate amounts of oats may be safely consumed by most adults with celiac disease. If further research continues to find no adverse effects from oat consumption, a consensus may emerge on the place of oats in the gluten-free diet. In the meantime, individual dietary prescriptions, routinely assessed for appropriateness using histologic and/or serologic studies, may be warranted to prevent unnecessary dietary restrictiveness and undesirable medical complications.”
