Doctors say there’s no reason for a gluten-free diet unless you have celiac disease or gluten sensitivity. But if you have regular digestive problems, such as recurrent diarrhea, bloating, or abdominal pain, or a history of hives, eczema, or food allergies, you may want to try a gluten-free experiment. Tim Buie, HMS assistant professor of pediatrics at MassGeneral Hospital for Children, is quoted.
