Whey Protein May Blunt Blood Glucose Spikes

Consuming whey protein before a meal could help reduce post-meal glucose spikes in people with type 2 diabetes. In a small study, 15 people with well-controlled type 2 diabetes (treated with metformin, sulfonylureas, or no medication) drank 250 milliliters of water (about a cup) mixed with either 50 grams of whey protein or a placebo (participants sampled each drink on different days), and then ate a high-carb breakfast. Blood glucose levels three hours after eating were 28 percent lower with the premeal whey than without. The glucose-lowering effect of the whey was greater than the 12 to 24 percent reduction in post-meal glucose levels typically seen with sulfonylurea drugs, the researchers say. (Note: The study was partly funded by the Milk Council.)
