It sounds like an unfolding epidemic: A decade ago, virtually no one in the U.S. seemed to have a problem eating gluten in bread and other foods. Now, millions do.
Gluten-free products are flying off grocery shelves, and restaurants are boasting of meals with no gluten. Celebrities on TV talk shows chat about the digestive discomfort they blame on the wheat protein they now shun. Some churches even offer gluten-free Communion wafers.
