Tell me about celiac disease?

The suitability of oats in the gluten-free diet is still somewhat controversial. Some research suggests that oats in themselves are gluten free, but that they are virtually always contaminated by other grains during distribution or processing. However, recent research indicates that a protein naturally found in oats (avenin) posseses peptide sequences closely resembling wheat gluten and caused mucosal inflammation in significant numbers of coeliac disease sufferers. Given such conflicting results, excluding oats is the only risk free choice for coeliac disease sufferers.
