Gluten is a protein found in grains primarily wheat, barley, and rye. Gluten allergies, like any other allergies, develop when our body’s immune system becomes over sensitive and overreacts to gluten.

It causes several digestive issues such as gassiness, bloating, abdominal pain, and diarrhea.  It is not essential that people with a wheat allergy will also be allergic to other grains. They may or may not be allergic.
