 In the investigators previous study, the acute administration with Whey protein resulted in postprandial insulinotropic and glucose lowering effects in type 2 diabetic subjects. This was associated with increased postprandial response of the total-GLP-1 and of intact-GLP-1, suggesting that the peptides generated from Whey protein may have dual beneficial effects increasing incretin production and decreasing incretin degradation by DPP-4 on glycemia regulation in subjects with type 2 diabetes.
