Tailored dietary re-education program leads to a significant improvement of fructose intolerance in adults

Background: Fructose, a hexose sugar consumed either naturally or as a sweetening additive, is absorbed by GLUT transporters in the small intestine. If this process fails, abdominal symptoms due to fructose intolerance (FI) may arise. Since the short-chain carbohydrates (FODMAP) low diet may improve functional gut symptoms, the effect of a personal alimentary program on gastrointestinal (GI) complaints was assessed in FI subjects. Methods: In total 679 subjects with a suggestive history of lactose/fructose intolerance and without evidence of other organic/functional diseases underwent H2-breath tests (Lactofan®)…
