Indigestible carbohydrates yield little or no energy but provide other benefits. Gi foods regulate insulin levels lipid levels in blood obesity. Introductionall cho is not equal in terms of nutrition. Viscous fibres trap nutrients & delay their transit through the digestive tract. As a result, glucose absorption slows & this helps maintain steady levels of blood glucose & insulin. Large fluctuations in blood glucose & insulin are thought to be associated with the onset of the most common form of diabetes. Glycemic effect - emic = blood extent food increases blood sugar want slow steady absorption, no spikes/ plunges.
