Inulin-type fructans (ITFs) are a type of fermentable dietary fiber that can confer beneficial health effects through changes in the gut microbiota. However, their effect on sensitivity and nutritional behavior is matter debate.We evaluated impact consuming ITF-rich vegetables daily microbiota, gastro-intestinal symptoms, food-related healthy individuals.A single group-design trial was conducted 26 individuals. During 2 wk, participants were instructed to adhere controlled diet based (providing mean intake 15 g ITF/d). Three test days organized: before after intervention 3 wk returning usual diet. We assessed nutrient intake, behavior, fecal microbiota composition, microbial fermentation, gastrointestinal symptoms.The major modifications during an increased proportion Bifidobacterium genus, decreased level unclassified Clostridiales, tendency decrease Oxalobacteraceae. These reversed intervention. The volunteers showed greater satiety, reduced desire eat sweet, salty, fatty food, trend increase hedonic attitudes towards some inulin-rich vegetables. Only flatulence episodes reported intervention, whereas intestinal discomfort, inversely associated with Clostridium cluster IV Ruminococcus callidus, improved at end intervention.A higher consumption allows substantial well-tolerated fiber, which may turn improve behavior. Moreover, it leads composition function. This registered clinicaltrial.gov as NCT03540550.
