Whey protein is a dairy protein, which is very high in nutritional value. It's a complete protein containing all the essential amino acids and it is also a source of branched chain amino acids too. It is used to promote fat loss by increasing lean muscle mass. So today, whey is no longer seen as just a secondary product in the dairy industry, it's become a very popular supplement.
Whey protein is the highest quality and best form of protein providing the body with the building blocks to produce amino acids used for building muscle tissue. Compared to other sources, whey protein is the best combination of amino acids in the right concentration for optimal performance in the body. Each of the smaller protein sub-fractions has unique biological properties. Hormonal and cellular responses are also enhanced by it.
Whey protein has been shown to increase protein synthesis. It also has powerful antioxidant effects enhancing glutathione levels. Glutathione is a tri-peptide containing one amino acid residue from: glutamic acid, cysteine and glycine. Glutathione is present in plant and animal tissues and protects skeletal muscle and other tissues from oxidative damage. Glutathione maintains compounds such as iron in its proper oxidation state in hemoglobin. Protein sources that contain high levels of cysteine are effective in maintaining and replenishing whole blood glutathione. Glutathione is the most important antioxidant found in the human body. It is essential for immunity, but also for general well being while reduced levels of glutathione are associated with a large list of diseases.
There have been concerns about the hormone content of whey protein because it's an animal based product. However, the same is true for anything we eat, especially if it is derived from animal sources, and even plants can also contain hormone or hormone-like compounds.
Whey concentrate protein is found in sports supplement protein powder. In the past few decades, whey protein powders have evolved from low-grade concentrates to high-grade concentrates and isolates. The latest type is hydrolyzed protein which is easier to digest.
Whey protein is especially important for bodybuilders and dieters because it helps muscles to recover and grow faster. For people who are on a diet, whey protein offers the possibility of balancing blood sugar levels. When blood sugar level is balanced, you have more energy but do not feel the need to eat a lot. As helpful as such a supplement may be, very high doses can overload the liver and you will not enjoy the benefits of a consistent lower amount.
Recent studies have found that it might reduce cancer rates, combat HIV, increase brain serotonin levels and reduce blood pressure. Isolate whey protein is also given to pregnant women and children. It has been scientifically proven to reduce cholesterol, working as an appetite suppressant, so it can be used for women who are trying to lose weight by eating less. Whey proteins have beneficial effects on the immune system as they help increase the antioxidant Glutathione which strengthens the immune system.
