Inulin, a fructooligosaccharide (FOS), is a soluble prebiotic fiber that is resistant to digestion and reaches the large intestine essentially intact. Intestinal probiotic bacteria consume Inulin and in turn, produce the short-chain fatty acids that nourish the cells lining the colon. Inulin thus helps to maintain intestinal health and function. Inulin has a pleasant flavor that adds a mild sweetness to foods and drinks, but has a very low glycemic index and will not negatively impact serum glucose levels.
According to the study at Jackson Lab, Sacramento, CA led by A.Ryazanov, mice fed by inulin lived 16% longer.
