Gluten is a type of protein found in wheat, barley, rye, and numerous other foods containing or made from these ingredients. Gluten can also be found in many non-food items, such as medicines, lipstick, and stamp adhesives.

If you have gluten intolerance or celiac disease, your body is unable to digest gluten. Consuming gluten may result in symptoms such as cramping, bloating, gas, and diarrhea. The only treatment is to eliminate gluten from your diet. Following a gluten-free diet can reverse any intestinal damage and nutrient deficiencies that may have occurred as a result of consuming gluten.
