Whey protein has become a popular supplement amongst athletes, but its traditional use has been in animal and food manufacturing as an additive to other foods. Modern supplemental whey protein is highly processed, but this processing may ironically increase the functionality of the supplement, rather than have detrimental effects. The benefits of whey protein stretch beyond its ability to facilitate skeletal muscle growth and some health benefits against serious diseases like metabolic syndrome and diabetes have been identified and observed for whey supplements. One benefit of whey protein appears to be its ability to reduce blood glucose levels which may be beneficial on insulin levels and this may cause some mild weight loss effects in those with insulin resistance. Weight loss is significantly associated with a number of health effects including a reduction in the risk of cardiovascular disease, suggesting that whey protein may be a significant health supplement for those that wish to avoid major western lifestyle diseases.
