May help treat type 2 diabetes

Type 2 diabetes is a chronic condition characterized by elevated blood sugar levels and insulin dysfunction. Insulin is a hormone that stimulates the uptake of blood sugar into cells, keeping it within normal levels. Whey protein has been shown to be effective at controlling blood sugar levels by increasing both insulin levels and sensitivity to its effects. When compared to other protein sources, such as egg whites or fish, whey protein appears to have the upper hand. These effects of whey protein may be akin to those of diabetes medicines like sulfonylurea.

As a result, whey protein can be utilized effectively as an adjunct treatment for type 2 diabetes. Taking a whey protein supplement before or after a high-carb meal has been found to lower blood sugar levels in both healthy and type 2 diabetic persons.
