Gluten is a protein found in wheat, barley, rye and the derivatives of these grains, including malt and brewer’s yeast. A gluten-free diet excludes all products containing these ingredients. Those who are gluten-free can still enjoy a healthy diet filled with fruits, vegetables, meats, poultry, fish, beans, legumes and most dairy products. Such ingredients are naturally gluten-free, and safe for individuals who do not have allergies to these respective food groups.
