What is whey protein?
Whey protein is made from cow’s milk and contains vitamins, minerals, protein, lactose and traces of milk fat. Most commonly, whey protein and casein are harvested during cheese production. Liquid whey is separated from casein while whey proteins are then isolated from the liquid whey and purified. Whole milk is only 6.25% protein. The two proteins that make up milk are casein (approximately 80%) and whey protein (approximately 20%). Whey is a complete protein, meaning it contains all essential and non-essential amino acids vital to your metabolism and good health. It is often referred to as the “Gold Standard” of protein as it is the most nutritious protein available. Studies have shown that undenatured whey protein can increase our blood levels of glutathione. Glutathione is an antioxidant which is essential to a healthy immune system. As we get older glutathione levels decrease and our immune system weakens. At the University of Nebraska Medical Center scientists were able to extend
Whey Protein a by-product of cheese manufacturing: supports protein synthesis and muscle development. Depending on the method of production, whey products can vary in the amount lactose, minerals, fat and proteins (including lactoferrin, beta-lactoglobulin, alpha-lactalbumin, glycomacropeptide, and immunoglobulins). Whey is a popular dietary protein supplement because it contains a full spectrum of essential amino acids and high concentration of branched-chain amino acids (BCAA). Amino acids are the basic building blocks of proteins that are essential to human metabolism, growth and development. BCAAs-leucine, isoleucine, and valine are needed for the maintenance of muscle tissue, preserving muscle stores of glycogen (a storage form of carbohydrate) and helping to prevent muscle protein breakdown during exercise. BCAA are readily oxidized as an energy source during stress.
Whey protein is made by distilling whey (a by-product of milk and cheese) into a high-quality powder that is fat-free, starch-free, and lactose-free. Whey has an advantage over other protein products. It enhances one of the body’s natural antioxidants which helps protect from free-radical damage. Whey protein contains amino acids that boost the immune system. It is easy to digest and is absorbed quickly into the blood stream through the intestines. Whey protein contains amino acids that may help decrease muscle soreness from exercise. There are also health benefits such as fighting infection and possibly fighting cancer. Whey protein seems to positively effect bone growth. Studies show that it may strengthen bones by increasing the level of bone proteins such as collagen. It helps in tissue repair and supporting the breakdown of muscles under stress. Whey protein dissolves easily in water and makes a convenient, healthy, low calorie drink for people on the go, people who exercise, work
Whey is a protein found in milk and has been promoted as having a number of health benefits. Milk has two proteins: Casein (approximately 80%) and whey protein (approximately 20%). Whey protein is used as a supplement in those interested in body building. A high protein intake can help many people restrict food intake since protein has satiating effects.
