title: Changes in plasma insulin related to the type of dietary carbohydrate in overweight hyperlipidemic male patients.
abstract: Five patients with mild diabetes mellitus or angina pectoris were studied, each of whom consumed two sequential diets containing 40 to 50% carbohydrate. When 75% of the dietary carbohydrate was derived from food containing polysaccharides, the mean plasma insulin response to oral glucose was decreased relative to that seen following complementary diets providing carbohydrate mainly as simple sugars. Under both dietary conditions, glucose tolerance was improved compared to that seen prior to the study. These results suggest that with sugar restriction an improvement in the efficiency of the pancreatic beta-cell mechanism occurs. This effect may have been mediated by changes in the rate of secretion of pancreatic glucagon, or by an enteric secretogogue of insulin.
