what is oligofructose
A few foods, including onions contain oligofructose. Oligofructose is a subgroup of the fiber known as Inulin. It is also known as fructooligosaccharide. Oligofructose is an insoluble fiber that is not digested in the upper gastrointestinal tract so we do not get any calories from it. Because it is still intact when it reaches the last region of your digestive tract, it is able to feed the host of microbes that live in your colon and large intestines.
