Inulin

Inulin is a water-soluble starchy fiber found in a wide variety of fruits, vegetables, and herbs. These include things like wheat, onions, bananas, and asparagus. It is often considered a health food, since it is a form of edible fiber which is not digested in the stomach, but facilitates probiotic (beneficial bacteria) further on in the digestive system. It is a "fructan" which means that it is composed of fructose molecule chains which are linked in a specific way which the body cannot digest.

Uses

Inulin seems to reduce triglyceride levels in humans by up to 19% after eight weeks of consuming 10-14 grams daily. Many suggest that it helps with weight loss, if for no other reason because it is a sort of filler with is not easily absorbed by the body. Inulin provides about 1.5 calories per gram, which is a relatively low caloric value.
Some also believe that moderate amounts of inulin help reduce the risk of diabetes. However, they also sometimes say that large quantities could actually cause type 2 diabetes, and therefore recommend deliberate but moderate consumption.
