Slow release carbohydrate and the treatment of diabetes
1981
Jenkins, David J.A. | Wolever, Thomas M.S.
Recent clinical trials suggest that diabetic control may be improved by emphasizing the quality, not quantity, of carbohydrate intake in the diet. The dietary fiber hypothesis states that feeding a high-fiber diet containing low energy-density foods slows the release of glucose from carbohydrate digestion, and promotes absorption over a greater length of small intestine; this prolongs and flattens postprandial blood glucose response. In contrast, diets containing refined sugars and little fiber are rapidly absorbed high in the small intestine, producing a large rise in blood glucose and a greater insulin response. Foods release their carbohydrate products of digestion at very different rates which may even be independent of fiber content. As this rate of release determines the glycemic response, which carbohydrate foods are eaten, rather than how much, should be a major consideration in dietary management of diabetes.
