Healthy adults had less bloating, increased well-being, and a small but significant weight loss on low-gluten compared with high-gluten diets, a study published in Nature Communications found. However, the study found those benefits may be linked to the diet’s dietary fiber rather than lack of gluten. “Gluten-free may not necessarily be the healthy choice many people think it is,” said Dr. Oluf Pedersen of the Novo Nordisk Foundation Center for Basic Metabolic Research at the University of Copenhagen in Denmark.
