Methods of using gamma cyclodextrin to control blood glucose and insulin secretion

Abstract

Disclosed are methods of producing a blunted postprandial glycemic response in an individual, and/or reducing postprandial insulin secretion, said methods comprising administering to the individual a nutritional or other product comprising gamma-cyclodextrin. Also disclosed are similar other methods directed toward the use of such products to provide weight and appetite control, to normalize blood glucose levels in individuals with impaired glucose tolerance, to minimize nighttime hypoglycemia in diabetic and non-diabetic patients, to prevent reactive hypoglycemia in susceptible non-diabetics, to normalize blood glucose levels in individuals with gestational diabetes or impaired glucose tolerance during gestation, and/or to provide a prolonged glycemic response during exercise. The methods are based upon the discovery that gamma-cyclodextrins are rapidly metabolized and absorbed in the small intestine, but subsequently result in a surprisingly blunted postprandial glycemic response and reduced insulin secretion.
