I have been told that I have a wheat allergy. What is that?

Probably not an entirely accurate statement. There is a growing recognition of a problem known as gluten sensitivity, gluten enteropathy, celiac disease, celiac sprue, or non tropical sprue. All of these conditions are caused by an intestinal allergy to gluten. Gluten is a glycoprotein found in wheat, rye, barley, and oats. Exposure of the small intestine to gluten causes inflammation and damage to the small bowel resulting in a variety of malabsorption problems, bloating, gas, pain, or diarrhea. Treatment is purely dietary, involving foods and medicines (including vitamins and minerals) which contain gluten.
