<human>: I've been hearing about this "gluten-free" diet. What is it all about?
<bot>: Gluten is a protein found in wheat, rye and barley. People who have Celiac disease cannot tolerate gluten. A gluten-free diet excludes foods containing gluten, such as bread, pasta, cookies, cakes, crackers, cereals, and other baked goods. The goal of the gluten-free diet is to reduce symptoms of Celiac disease and improve health.
