Gluten-free diets may be linked to increased type 2 diabetes risk
Gluten-free foods often have less dietary fiber and other micronutrients, making them less nutritious and they also tend to cost more. People without celiac disease may reconsider limiting their gluten intake for chronic disease prevention, especially for diabetes.
Gluten intake may not exert significant adverse effects on the incidence of [type 2 diabetes] or excess weight gain. Limiting gluten from diet is thus unlikely to facilitate type 2 diabetes prevention and may lead to reduced consumption of cereal fiber or whole grains that help reduce diabetes risk.
