What is a gluten-free diet?

Gluten is a protein found in wheat, rye and barley. In some genetically predisposed children, food containing gluten causes small-bowl mucusal damage resulting in a disease called gluten-sensitive enteropathy or celiac disease. The treatment is a strict gluten-free diet i.e. elimination of wheat, rye and barley products from the diet. Gluten-free foods are commercially available.
