Benefits of Whey Protein

I occasionally use a protein powder as a snack or part of a meal replacement. While I don’t believe we can truly replace a meal with supplements, sometimes protein powders can be a handy way to boost our protein intake. For people that tolerate dairy well, whey protein can be a good choice because it mixes easily and tends to be very palatable. Because of its particular amino acid compositions, whey protein also offers some benefits that other protein powders don’t. For instance, in a small study participants given whey protein, who otherwise ate as they wished, experienced a slight weight loss compared to those given soy protein who had no change in weight. This group also saw a reduction in ghrelin, a hunger hormone that makes us crave high calorie foods. Whey protein is also commonly used by athletes and has been shown to reduce post-workout muscle damage. Whey protein is high in branched-chain amino acids like leucine that have been shown to improve upper body strength and lean body mass. Whey protein can also help seniors shape up by helping improve muscle mass and function. In fact, whey protein led to skeletal muscle improvements that were superior to those from control groups of participants taking an equivalent amount of amino acids, the building blocks of proteins like our muscles.

In addition to helping body composition, whey protein can improve our well being in several key ways. One study demonstrated significant decreases in cholesterol, triglycerides and fasting insulin levels when participants consumed whey protein, but not when they received casein protein. Whey protein may also help with detoxification and cancer prevention since it is a source of cysteine, which our bodies need to make glutathione, a critical antioxidant for protecting our bodies from toxins. There are also immune benefits from whey protein as demonstrated in a study where elderly subjects receiving pneumonia vaccines produced more of the protective antibodies against the pneumonia-causing organisms. Whey protein is also a good choice as part of a protocol to speed healing from surgery.
