Whey protein, which is in most protein supplements, is derived from milk. During the pasteurization process the milk is filtered and a foamy substance is left over. That foamy substance is whey. For years farmers and scientists simply used to throw the whey away or feed it to the animals until they found that it is a superior form of protein.
In fact whey protein is the highest BV(biological value) of any protein.
Remember one thing: What does quality protein mean and how is it measured? Protein quality is measured by the number of essential or indispensable amino acids provided and by the digestibility of the protein. Protein quality is measured by the Biological Value(BV). BV is a value that measures how well the body can absorb and utilize a protein. The higher the Biological Value of the protein you use, the more nitrogen your body can absorb, use, and retain. As a result, proteins with the highest BV promote the most lean muscle gains. Whey protein has the highest BV value, rating at 104. Egg protein is only second to whey rating as a 100 with milk proteins being a close third rating as 91. Beef rates as an 80 with soy proteins(tofu included) a distant 74. Bean proteins, due to the fact that are plant-based proteins, only rate a 49.
I am only trying to show you the BEST way. There are other ways, but there is only one BEST way
I take about 5 protein shakes a day as well as eating 1-2 food meals and have done so for about 5-6 years. I eat 1-2 food meals and then have about 4-5 shakes a day. I almost always eat 6 meals a day. 5 used to be my average, but I try to keep it to 6. I have a before bedtime MM shake.
I use Pure Advantage and Cytosport products. Other brands are good such as Optimum Nutrition, Beverly Nutrition, BSN, and others.
Taking protein within 30 minutes after working out is best to return your body from catabolic(muscle breakdown) to anabolic(muscle recovery).
I will take the following info directly from my Smart Nutrition Book which is part of the A.B.1 Training Systems Program.
1. Protein Sources
i. The most important choice here is quality.
ii. Taste should not be a factor. Think about what it is doing to your body.
iii. Muscle Milk(RTDs), Nectar, Optimum Nutrition, and Pure Advantage are all great whey protein brands.
iv. GNC’s Protein 95 is a great (Supro Soy) soy protein source. Spiru-Tein is also a good brand choice for soy as well.
v. The other option is a protein bar. Balance, Zone, Nitrotech or Detour brands are some of the best bars to choose.
