Gluten

Gluten is a special type of protein that is commonly found in rye, wheat, and barley. Therefore, it is found in most types of cereals and in many types of bread. Not all foods from the grain family, however, contain gluten. Examples of grains that do not have gluten include wild rice, corn, buckwheat, millet, amaranth, quinoa, teff, soybeans, and sunflower seeds.
