Viscosity a physicochemical property which is the
main cause of increasing viscosity in the intestine slows
intestinal transit, delays gastric emptying (Anderson and
Chen 1986), and slows glucose and sterol absorption by
the intestine (Kahlon and Chow 1997) and lower serum
cholesterol, postprandial blood glucose, and insulin levels. These health benefits are related to viscous fibers or
soluble fibers (SDF).
