Whey is one of the two proteins found in milk. It is obtained as a by-product during the cheese-making process. It is a mixture of globular proteins that is separated from whey. It is a very rich source of amino acids, and contains minimal fats and cholesterol. Once its nutritional properties were discovered, it began to be used by athletes, bodybuilders, and sportsmen. Today, it is gaining popularity among people of all age groups due to its numerous health benefits. Whey protein is a very good source of essential amino acids (EAAs) and branched-chain amino acids (BCAAs). EAAs and BCCAs that are present in whey help in the maintenance of muscle tissues, as well as protein synthesis by the body. It contains leucine, which is an amino acid that plays an important role in protein synthesis and muscle growth. It also contains cysteine, which is essential for the production of an antioxidant called glutathione. Being an antioxidant, glutathione helps prevent oxidative damage that is caused by free radicals. Antioxidants also help strengthen the immune system. Proteins isolated from whey could help in losing and maintaining weight. It helps maintain cardiovascular health and improves memory. It also provides nourishment to infants. It can also be used by cancer patients. Weight Loss and Weight Management This protein contains minimal fat and cholesterol and is consumed as a pre-exercise meal. Studies suggest that the amino acids present in it help improve the body composition by promoting fat loss. It has bioactive components that reduce appetite and burn down fats. Nourishment for Cancer Patients Proteins isolated from whey provide the essential nourishment that cancer patients require, but are not able to get, due to loss of appetite and other adverse effects that are associated with cancer treatments. It is soluble, easily digested, and easily absorbed by the body. It also strengthens the immune system of cancer patients. Memory Improvement Studies show that it improves memory, cognitive performance, and performance under stress. Cardiovascular Health Inclusion of this protein in one's daily diet is believed to lower the risk of cardiovascular disorders. It also helps lower blood pressure and cholesterol levels, thereby preventing many kinds of cardiovascular disorders. Diabetes Whey is beneficial for individuals affected by Type 2 diabetes, as its biological value is high. Diabetics can include it in their diets to control blood sugar levels. Infant Nourishment Whey is being included in infant food formulas, as it is essential for their healthy growth and development. It provides them with adequate nourishment, as it contains similar components that are found in breast milk. It is also beneficial for pregnant women, as it provides them with the increased amount of protein that their body demands. Aging This protein also lowers the risk of sarcopenia, which is the gradual loss of muscle mass or weakening of muscles that is associated with aging. It reduces loss of protein, and promotes the process of protein synthesis in the body. Whey protein is available as a dietary supplement in the form of powders, drinks, and concentrate. Though it offers numerous health benefits, it's still advisable to consult your healthcare provider before you start taking this supplement.
