Part #2 – Protein: Why Whey?

Protein is a macronutrient involved in repairing and building muscle tissue. Athletes and bodybuilders of all levels and from across the world realize the importance of protein for muscle growth. In addition to many whole food protein choices, there are countless protein supplement options. And therein lies the dilemma: which type of protein supplement should you take, and when?

Of the various types of protein consumed, some of the best-known whole food protein sources are chicken, beef, eggs, fish and legumes. Some of the best-known protein powder supplement sources include whey protein, casein protein, egg protein, beef protein, and various other veggie protein sources. One thing to consider when choosing your protein supplement source is its Biological Value (BV). BV is a measure of how well a protein source is absorbed and how well it's utilized by the body. Originally, egg protein was ranked as having the highest BV, at 100. But after some time, it was realized that whey protein was ranked highest, at 104. Other protein sources' rankings include: milk at 91, beef at 80, casein at 77, and soy at 74. So, based on this information whey protein is the best protein source to consume when you need to get protein to your muscles, fast – like right before or right after your workouts.
