Gluten-free Diets Questioned

Tuesday, 21 Feb 2012 02:12 PM




Italian researchers are questioning the benefits of gluten-free diets for most people, suggesting they may be a waste of money for some.
University of Pavia researchers, writing in the Annals of Internal Medicine, suggested the newly recognized condition known as “nonceliac gluten sensitivity” is not well-defined enough to justify the added expense of a gluten-free diet.

“Recent studies support the existence,” of the condition, the authors wrote, but added: “The lack of an unambiguous definition of nonceliac gluten sensitivity [is] a major pitfall” to the argument that a gluten-free diet will help.

Gluten is a component of wheat, rye and barley flour. For people celiac disease, foods that contain gluten trigger the immune system to attack the small intestine and a diet free of gluten is typically recommended.

But in recent years more people have been told they have “nonceliac gluten sensitivity,” said Dr. Gino Roberto Corazza, a co-author of the new study.

“Considerable debate about nonceliac gluten sensitivity has recently surfaced on the Internet, with a sharp increase in forums, patients or patient groups, manufacturers, and physicians advocating a gluten-free diet,” the researchers wrote. “Claims seem to increase daily, with no adequate scientific support to back them up.”
