I've been told that I'm allergic to gluten. Is this true, and how do I know for sure?

It's true!  Gluten is a protein found in wheat, rye, barley, and oats. People with celiac disease must avoid foods containing gluten, as it can damage the lining of the small intestine. Symptoms of celiac disease include abdominal pain, bloating, diarrhea, weight loss, fatigue, constipation, and anemia. To test if you're sensitive or allergic to gluten, try eating a few slices of bread or a slice of pizza without gluten. If your symptoms worsen, then you are likely sensitive to gluten.
