Arabinoxylan Interactions Overview

Arabinoxylan is a type of dietary fiber present in the cell walls of cereal grains such as wheat, corn, rice, rye, oat, and barley. It has a structure comprising a xylose backbone with arabinose side chains and can be extracted from byproducts of wheat-flour processing. In natural medicine, arabinoxylan has been utilized to address conditions like diabetes, impaired glucose tolerance, and metabolic syndrome. However, the evidence supporting its effectiveness in these areas is currently insufficient. Mechanistically, arabinoxylan functions as a prebiotic, fostering the growth of bifidobacteria in the gut. It may also reduce colonic protein fermentation while boosting the production of short-chain fatty acids. Arabinoxylan in clinical research has demonstrated hypoglycemic effects by lowering postprandial glucose levels and hypolipidemic effects by reducing serum triglycerides.
