Fructooligosaccharides (FOS) also sometimes called oligofructose or oligofructan, are oligosaccharide fructans, used as an alternative sweetener.
Fructo-oligosaccharides are used for constipation, traveler’s diarrhea, and high cholesterol levels.
Fructo-oligosaccharides are also used as prebiotics. Prebiotics act as food for “good” bacteria in the intestine. Don’t confuse prebiotics with probiotics such as lactobacillus, bifidobacteria, and saccharomyces, which are live organisms that are good for health. People sometimes take probiotics by mouth to increase the number in their intestine.
In foods, fructo-oligosaccharides are used as a sweetener.
FOS has been a popular sweetener in Japan for many years, even before 1990, when the Japanese government installed a “Functionalized Food Study Committee” of 22 experts to start to regulate “special nutrition foods or functional foods” that contain the categories of fortified foods (e.g., vitamin-fortified wheat flour), and is now becoming increasingly popular in Western cultures for its prebiotic effects. FOS serves as a substrate for microflora in the large intestine, increasing the overall gastrointestinal tract (GI Tract) health. It has also been proposed as a supplement for treating yeast infections.
Several studies have found that FOS and inulin promote calcium absorption in both the animal and the human gut. The intestinal microflora in the lower gut can ferment FOS, which results in a reduced pH. Calcium is more soluble in acid, and, therefore, more of it comes out of food and is available to move from the gut into the bloodstream.
FOS can be considered a small dietary fibre with (like all types of fibre) low caloric value. The fermentation of FOS results in the production of gases and acids. The latter provide some energy to the body.
Fructo-oligosaccharides seem to be safe when taken in less than 30 grams per day. They can cause intestinal gas (flatulence), intestinal noises, bloating, stomachcramps, and diarrhea. These effects are usually mild if the dose is less than 10 grams per day.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Not enough is known about the use of fructo-oligosaccharides during pregnancy and breast-feeding. Stay on the safe side and avoid use.
None are recorded.
