There is a menace in our supermarkets. And it is nothing short of a dietary WMD: A Weapon of Mass Diarrhea. Its name is gluten. Gluten is a mixture of proteins found mostly in wheat, but also in barley, rye, and oats.
These grains make up many of our breads, pastas, granolas, noodles, tortillas, and beers. That's trouble for many people who suffer from celiac disease, an autoimmune disorder in which gluten causes the body to attack the small intestine.
