The native mixed linkage beta-glucan of cereals is classified as a soluble dietary fibre, with rheological properties generally similar to guar gum and other random coil polysaccharides. The ability of oat and barley products to attenuate postprandial glycemic and insulinemic response is related to content of (1 -> 3)(l -> 4)-beta-D-glucan (beta-glucan) and viscosity. A role of viscosity of beta-glucan has not been directly demonstrated for lowering of serum cholesterol levels, and not all studies report a statistically significant lowering. The wide range of effectiveness reported may partially be explained by the properties of the beta-glucan in the diets used, as well as the dose. Crown Copyright (c) 2007 Published by Elsevier Ltd.
