Fructooligosaccharide, or FOS, refers to a short chain of fructose molecules with a natural, mildly sweet taste. FOS is a soluble, but indigestible carbohydrate with a low caloric value, typically derived from inulin in Jeruselum artichoke or other tubers in the West. In Japan, where it has been popular for many years, it is usually derived from Aspergillus cultured on saccharose.
FOS improves overall health of the gastrointestinal tract by supporting the growth of "friendly" bacteria in the large intestine. In doing so, it appears to increase calcium absorption, and may also increase magnesium absorption. Some references to FOS indicate it may assist in the prevention of yeast overgrowth.
FOS naturally occurs in many fruits and vegetables, particularly those with edible rhizomes, bulbs and fleshy tubers, such as sweet potato, chicory root, garlic and onions, and to a lesser extent in barley, bananas and tomatoes. The Jerusalem artichoke contains the highest amounts of FOS.
