Protein Royalty

When you consider that protein is the main component of skin, muscle, hair, and nails, it becomes pretty self-evident why getting enough of this nutrient in our daily diet is so important. In fact, the word protein comes from the Greek word prota meaning “of first importance” and that should give you a hint of what nutritionists think of this important food component.

Unfortunately, many athletes, kids and the babyboomer aren’t getting enough of this vital nutrient and as a result they are paying a price for it in premature aging. But it is not difficult to consume adequate levels of protein once you know what foods are high in it. Best sources of protein are eggs, lean meat, poultry, fish, milk, cheese, yogurt and some legumes particularly soybeans and lentils.

The King of Protein

Whey and casein are two major types of protein found in milk. Whey was originally isolated as a by-product of cheese production. It 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 on the market, 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 protein contains the highest concentration of branched-chain amino acids (BCAA) of any protein source. BCAA’s 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 - Casine

Casein Protein is also derived from milk and is the main component of the “curds and whey” combination produced in the cheese-making process. It has been used for many years in the supplements industry as a source of high-quality protein. Like whey, it 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 lean tissue 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 us boomers.



• Casein Protein contains high amounts of glucogenic aminos (threonine, glutamine, arginine). These aminos assist in glucose production for energy during exercise and other physical activities. Similar to glutamine, they also have been shown to slow down muscle breakdown.
