How fiber prevents diabetes and obesity

Scientists have known for the past twenty years that a fiber-rich diet protects the organism against obesity and diabetes but the mechanisms involved have so far eluded them. A French-Swedish team including researchers from CNRS, Inserm and the Université Claude Bernard Lyon 1 (Unité Inserm 855 “Nutrition et Cerveau”) has succeeded in elucidating this mechanism, which involves the intestinal flora and the ability of the intestine to produce glucose between meals.
