Whey protein and supplements made from whey protein are natural proteins made from cow's milk. Athletes, bodybuilders and weightlifters are dedicated consumers of whey protein. Nutritionists have concluded that this form of protein is vital as a source of amino acids. Amino acids fuel the body and helps maintain muscle mass. Supplements with whey are excellent sources of amino acids. They are necessary for growth and maintenance of all bodily tissues including bone, skin, nails, and muscle. Whatever your goal is bodybuilding or losing weight on a fat restricted diet, whey protein needs to be part of your arsenal.
There are three forms of whey called protein isolate, whey protein concentrate, and hydrolyzed whey protein. Of the three, isolate is by far the purest. Although all three provide significant health benefits having high amino acid content, whey isolate is the best. When researching products containing whey, look for protein isolate in the ingredients.
Whey protein is one of the best sources of branched chain amino acids called BCAAs. BCAAs are very important to preservation of muscle mass and directly absorbed into muscle tissue. BCAAs are converted to glucose and burned quickly during intense physical activity or exercise. Whey isolate is reputed as being highly valued by sports nutritionist.
BCAAs are made of Valine, Isoleusine, and Leucine. Leucine is most effective at preventing tissue damage which whey contains. In fact, whey contains more Leucine than milk, soy, or eggs. Leucine helps regulate blood sugar and reduce body fat. Research indicates that people with diets rich in Leucine have a higher ratio of muscle to body fat. Whey can promote weight loss by stimulating release of two appetite suppressant hormones called Cholecystokinin (CCK) and Glucagon-like Peptide-1 (GLP-1). Whey boosts the immune system by increasing levels of Glutathione which is the bodies' most abundant antioxidant. Preliminary research indicates whey may also help lower blood pressure in people with borderline hypertension. Whey protein digests easily, including in most infant formulas, and an excellent supplement for the elderly and patients diagnosed with chronic wasting conditions such as AIDS and cancer.
If you are a serious athlete, body builder, trying to lose weight, or have a compromised immune system, then whey is strongly recommended. Lastly, the natural aging process causing loss of muscle can be slowed by having whey as part of your diet.
Whey protein isolate contains very little fat and lactose. Isolate is a great choice for those who are on reduced-fat diets. When purchasing whey products, inspect the label for amounts of protein, carbohydrates and fat in each serving. Look for supplements that contain 100% cold filtered whey isolate. An added benefit are supplements high in immunoglobins, lactoferrins, glycomacropeptides and BCAA lean mass activators.
