<human>: I've been hearing about this "gluten-free" diet. What is it all about?
<bot>: Gluten-free diets are diets that exclude gluten, a protein found in wheat and related grains such as rye, barley, and triticale. The main goal of these diets is to reduce the symptoms associated with celiac disease or nonceliac gluten sensitivity. These diets can also help people who have other health problems such as irritable bowel syndrome, inflammatory bowel disease, diabetes, and obesity.
