View clinical trials related to Dietary Fibers.
Filter by:Dietary fibers are generally not degraded by the endogenous digestive enzymes, but rather by the complex ensemble of microorganisms that reside in the human gut [1]. This ensemble, collectively known as the human gut microbiome, plays a key role in breaking down, fermenting, and ultimately converting such dietary fibers into a variety of beneficial metabolites, including most notably, short chain fatty acids (SCFA). These end products of fibers' fermentation affect host metabolism, immunity, and physiology, and have been implicated in multiple diseases including obesity, metabolic syndrome, diabetes, and cardiovascular diseases. Intermediate fasting, and in particular circadian intermediate fasting (i.e. 16 hours of fasting followed by 8 hours of allowed eating), has been shown to have positive associations with multiple health conditions as obesity, diabetes mellitus, cardiovascular disease, cancers, and neurologic disorders In this study, we will try to answer open questions utilizing the long fasting period during the day to investigate the isolated effect of dietary fiber consumption, uncovering the degradation effect, but not the bulking effect, on the microbiome and the host physiology, and in particular its glucose response.
NUTRIOSE is a food ingredient defined as a carbohydrate polymer of vegetable origin (wheat starch or corn) with a degree of polymerization ≥ 3 and chemically transformed. It is soluble in aqueous solution, very poorly digested in the small intestine, it mostly reaches the colon where it stimulates fermentation. AFSSA, in its opinion of July 30, 2007, considers that this ingredient is a "soluble dietary fiber." The objective of this research is to determine, among healthy subjects, the effect of this dietary fiber on changes in gut microbiota and digestive tolerance during a 28 days consumption. Microbiological analyzes will be performed by RT-PCR. Digestive tolerance will be measured by the intelligence of a questionnaire by volunteers.
