Gluten-Free Dieting Grows, But Incidence Of Celiac Disease Is Steady

September 6, 2016: 12:00 AM EST
Six years of health survey data collected from more than 22,000 people shows that celiac disease remains a problem, but not a growing one, contrary to some reports. The proportion of people diagnosed with the disease, characterized by an allergic reaction to the gluten protein found in wheat-based products, has stayed the same. But U.S. researchers noted that the number of non-celiac people following a gluten-free diet has grown. The numbers gleaned from the sample were extrapolated to the general population: about 1.76 million Americans have celiac disease; 2.7 million non-celiacs follow a gluten-free diet. This may be due to public perception that gluten-free may be healthier; that gluten-free products are increasingly available; or that some people self-diagnose a gluten sensitivity.
