Inulins are a group of naturally occurring polysaccharides produced from many types of plants. The inulins belong to a class of dietary fibers known as fructans and are used by some plants as a means of storing energy, typically found in roots or rhizomes. Inlulin is a soluble fiber, and may help lower blood cholesterol and glucose levels. Since the human digestive track cannot break down inulin into monosaccharides, it does not elevate blood sugar levels, and may, therefore, be helpful in the management of diabetes. Inulin also stimulates the growth of gut bacteria, due to its indigestible nature and bioavailability for gut bacteria. Inulin has a propensity to cause gas and bloating in those having consumed it in moderate to large quantities, in particular, individuals unaccustomed to it.
