Whey protein is a kind of protein that is found in cow’s milk. About eighty seven percent of cow’s milk is water and milk solids constitute the remaining portion. The solids present in milk include fat, lactose, protein and certain other minerals in minimal amounts. In that, eighty percent of the protein portion is constituted by casein and the rest of it is whey protein.
Compared to casein protein, whey protein gets digested more quickly by the human body. Moreover, biological value of whey protein is relatively higher. It is indeed the most nutritious protein source available.
Since whey protein comes from cow’s milk, for making its supplements it need to be separated from fat and lactose, using one of several methods available. At the end of the extraction process, a powder of concentrated whey protein is made.
A much more expensive form of whey protein is termed as whey protein isolate. Whey protein isolate is ninety percent protein and contains only negligible traces of fat. In order to manufacture whey protein isolate, a much more longer and more intricate filtering process is necessary.
Whey protein is extremely popular among those who crave to build a ‘muscle body’. This is because whey protein is the most comprehensive and easily digestible protein available. Moreover it contains natural branched chain amino acids, (leucine, isoleucine, and valine), which adds muscle mass considerably. These amino acids will be used by skeletal muscles directly and is thereby extremely beneficial to those who are engaged in strenuous sports activities. Moreover, compared to other protein supplements, whey protein is cheaper.
The total amount of protein, from all the different diet sources that should daily reach your body is about 1.5 g of protein per pound of body weight. Along with other dietary protein sources such as poultry, green vegetables, seafood, meat etc, protein shakes made with whey protein will see to it that your body gets muscular.
