Brief Summary
The purpose of this study is to assess the prevalence of Gluten Sensitivity, by a double-blind placebo-controlled challenge with gluten, followed by two months period of Low-FODMAPs (Fermentable Oligosaccharides Disaccharides Monosaccharides And Polyols) diet, in patients spontaneously adherent to gluten free diet because of symptoms upon gluten exposure and in whom diagnosis of Celiac Disease and Wheat Allergy has been ruled out.
