Benefits of Whey Protein
There are several benefits to choosing whey protein
over other protein sources. Whey protein has an extremely high biological value (BV) afforded to it (Whey Protein BV = 104 with Whey Peptides having a BV between 110-159). The BV of a protein is essentially a measure of how well it is utilized by the body, and takes into account the amino acid profile, solubility and digestibility of the protein. Whey protein is an ideal source of protein post workout as it is absorbed extremely quickly to help rebuild damaged muscle.
Whey protein contains the highest percentage of BCAA's of any protein source as well as high levels of essential amino acids. BCAA's protect muscle from protein breakdown and help to stimulate protein synthesis or muscle growth. Whey protein also contains protein fractions. These are the active components that high quality whey proteins should contain. These include Alpha-Lactalbumin, Immunoglobulins, Glycomacro-peptides and Lactoferrin. These components possess properties that support the immune system, act as antioxidants and can help with cell growth and repair in the body.
Essential amino acids are important as the body cannot manufacture these itself and relies on getting them from the diet.
Whey protein may also suitable for some lactose intolerant individuals as it is extremely low in lactose with some whey protein isolates being virtually lactose free.
High quality whey proteins tend to be relatively expensive, with whey protein isolates being the most expensive source of protein available. Many companies produce several different sizes with the larger containers being more economical. Whey protein is also low in the essential amino acid phenylalanine as well as glutamine when compared to other protein powders. Many brands add these two components to help increase the BV of the protein and improve its effectiveness.
With so many protein powders on the market you could be excused for not worrying too much about what sort of protein you use. Many people probably don't care about whether the protein they are using is instantised, partially hydrolysed, ultrafiltered, ion exchange whey protein isolate with low molecular weight whey peptides, featuring full spectrum whey protein fractions, including Glycomacropeptides, Beta Lactoglobulin and Lactoperoxidase. If you understood all of that then you probably don't need any help. But if you're like the majority of people who base their decision on whatever they find tastes best or which one your favorite bodybuilder used to pack on twenty kilo's of solid muscle, then you may find some of the following information useful.
While it may not be necessary to know exactly what all these terms mean, if you want to be able to make an informed choice and get the most from your training, it can be of benefit to know a few of the basics. Article Source: EzineArticles .com /4202137
