Fructooligosaccharide

Fructooligosaccharide (FOS) is a type of oligosaccharide derived from fructose units. It is a prebiotic, meaning it promotes the growth of beneficial gut bacteria. FOS is commonly used as a sweetener and is also found in a variety of plants including onions, garlic, and asparagus. It is not fully digested by the human body, thus providing fewer calories while promoting gut health.
