Whey protein appears to have insulinotropic and glucose lowering properties in healthy adults (6-9), and also in individuals with type 2 diabetes (10,11). The magnitude of postprandial blood glucose reduction following ingestion of whey protein is comparable to that observed with pharmaceutical interventions such as sulfonylureas (12) or nateglinide (13). These findings imply an important role for whey protein in the management of type 2 diabetes (10).
