Whey Protein The King Of All Protein
When you consider that protein is the main component of lean muscle mass, finger and toe nails, and hair, it becomes pretty self-evident why getting enough of this nutrient in our daily nutrition plan is so important. In fact, the word protein comes from the Greek word prota meaning “of first importance” and that should give you an idea of what nutritionists think of this important food component.
Unfortunately, many athletes, kids and babyboomers aren’t getting enough of protein and as a result they are paying a price for it in premature aging. But it is not difficult to intake proper portions of protein once you know what foods are high in it. Best sources of protein are eggs, lean red meat, chicken breast, fish, milk, cheese, yogurt and some legumes particularly soybeans and lentils.
The Protein King
Whey and casein are two major types of protein found in milk. Whey was originally isolated as a by-product of cheese production. whey protein offers one of the highest quality sources of proteins you can use. Those in the know consider it to be the Mercedes of protein supplements. Even though it is the most expensive protein source available, we felt that its benefits justified the price. Let’s take a look at some of those benefits:
* Whole whey protein isolates contain approximately ten percent intact immunoglobulin proteins. These proteins have been shown to help support the body’s immune system.
* Whey proteincontains the highest concentration of BCAA’s of any protein source. Branch Chain Amino Acids play an integral part in muscle metabolism and help spare lean muscle tissue.
* Whey Protein helps increase the body’s natural production of glutathione – the body’s most important naturally occurring antioxidant.
* Whey Protein isolates contain quadrapeptides which have been shown to have pain killing effects.
Biological Value (BV) is a measure of how well various proteins are utilized by the body. Due to its excellent amino acid profile, solubility, and digestibility, whey has a very high BV.
The Prince - Casein
Casein Protein is also derived from milk and is the main component of the “curds and whey” combination produced in the cheese-making process. Casein Protein has been used for many years in the supplements industry as a source of high-quality protein. Like whey, casein too has some outstanding benefits:
* Casein is digested very slowly thus helping to regulate (slow down) transit time of other proteins through the intestinal tract. This slowing of transit time helps increase the absorption of amino acids, peptides, and whole proteins. This helps to prevent muscle breakdown during sleep or between meals.
* Casein is very high in the peptide form of the amino acid glutamine (20.5%) – higher than whey, soy, and eggs. High concentrations of this amino acid can help spare lean muscle tissue, something extremely important to an aging adult.
* Casein Protein contains high amounts of glucogenic aminos (threonine, glutamine, arginine). These amino acids assist in glucose production for energy during exercise and other physical activities|strenuous activity and healthy training. Similar to glutamine, they also have been shown to slow down muscle breakdown.
