Definition

A gluten-free diet is an eating plan that cuts out foods that have a protein in them called gluten. Gluten helps foods keep their shape. It's found in grains such as wheat, barley and rye. It's also found in crosses of these grains, such as a mix of wheat and rye called triticale.

Some people have health conditions such as celiac disease that cause problems when they eat gluten. If your healthcare professional recommends a gluten-free diet to manage your condition, you'll have plenty of foods to choose from. Some foods that are made with gluten are available in gluten-free versions. And many foods are naturally gluten-free. These include meats, seafood, fruit, vegetables and some grains.
