Benefits Of Whey Protein
What Is Whey Protein?
Whey protein is found in milk. In whey protein supplements, the whey found in milk is separated from the fat and carbohydrates using various processes to ensure that on average 80%-95% of the weight of the product is pure protein.
Why Is Protein Beneficial?
Protein is made up of amino acids, which are the used by the body build and repair muscle tissue (amongst being used for countless other processes). Therefore and adequate intake of protein is essential when trying to build muscle mass and strength.
Weight training, or any sporting activity for that matter is a catabolic activity, meaning it breaks down muscle tissue. After these activities proper intake of protein is essential to prevent continued muscle breakdown and start actually building new muscle mass.
Why Is Whey The Best Source?
Whey protein has risen to the top because of a few factors that separate it from other protein sources.
Firstly whey protein has the fastest rate of absorption of any protein source. As whey is the purest source of protein it is digested and absorbed quickly resulting in a fast rise in amino acid concentration. This means that whey is the best source of protein for stopping muscle breakdown after strenuous activity.
Secondly, whey has the highest biological value score of all protein sources. In essence, whey delivers more protein per serving than any other protein source.
Biological Value Of Proteins
The biological score of protein sources refers to how much ingested protein can actually be broken down and used by the body to build new proteins.
Initially you may think that the BV score of proteins is the only factor to consider when choosing a protein source however, other factors such as rate of digestion must be considered.
Whey is the fastest digesting source that delivers the most protein, however due to its quick absorption it only delivers protein in the short term. This means that after about 2 hours either more whey protein must be consumed or there will be no amino acids available.
In contrast a protein source such as casein digests much slower, almost ‘drip feeding’ your body with a constant flow of amino acids for up to 4 or 5 hours. The amount of protein per serving is less and there is no spike in amino acid concentration, but the body does continue being fed amino acids in the long term.
Why Take Whey Protein?
Whey protein has the biggest benefit to muscle growth as it delivers more amino acids per serving and sparks muscle growth more than any other protein source. Whey is ideal to take in the morning and almost essential to take around your workouts to insure you against muscle breakdown.
Other protein sources such as chicken, beef or powdered supplements such as egg protein, casein, or even protein blends also have their place to ensure long term amino acid utilisation, but whey will always be the king for muscle building.
Conclusion
Whey is by far the most popular protein supplement. Whey simply delivers the most amino acids and sparks protein synthesis (muscle building) more than any other protein source. Other protein sources do have their benefits for preventing muscle breakdown, but nothing builds muscle like whey protein.
