Why Whey Protein Is So Healthy?

Some ignorant nutritionists and doctors believe that why protein is bad for you.

Whey protein  is a unique source of high quality, biologically active protein and protein fractions.  Whey is more easily digested and contains high concentrations of  leucine, isoleucine, and valine.,compared to:

  • Soy
  • Beef
  • Egg
  • Pea
  • Rice 
  • Casein

 whey is more easily digested and contains high concentrations of the essential amino acids including leucine, isoleucine, and valine. Uneducated nutritionists and doctors think that whey protein is only a bodybuilding supplement to get muscular. They are so wrong.

Whey can offer far more in the way of health benefits to people. When whey is:

  •  Low temperature filtration ( less than 42 degres F)
  • Isolate
  • Microfiltered
  • Spray drying process

It will produce the purest form of undenatured bioactive whey protein. It will preserve IgG, lactoferrin, IGF, and glycomacropeptides, unlike most of the protein you buy in your store, or at your gym. Some ridiculous studies have been done with cheap protein and huge amonts on animal in order to trash whey protein.

  • A good whey protein must have a digestibility of 95
  • A PER of 3.2
  • A  BV of 104

The protein fractions formed by the amino acids bring many biologically significant health benefits

Helps fat soluble vitamin  utilization

Beta-lactoglobulin comprises 55-65% of whey and has binding sites for minerals and fat soluble vitamins like vitamins A, D, and E. Research shows that Beta-lac is capable of transporting compounds like vitamin E and vitamin A into the body so they may be utilized. It is also an antiviral.

Lactalbumin is rich in lysine, leucine, threonine, tryptophan, and cystine. Making up about 15-25% of whey protein, Alpha-lac is very easily digested and forms the basis of human breast milk. The Alpha-lac fraction is often extracted from whey and used as a pure source of protein for high quality infant formulas. Due to its ease of digestion and outstanding amino acid profile, Alpha-lac is also used in formulations for adults on restricted protein intakes due to disease conditions or other digestive disorders. Recent research suggests Alpha-lac may have anti-cancer properties due to the antioxidant benefits of glutathione. Glutathione is produced from the amino acids in whey and is the “master antioxidant” produced by the body. Glutathione also supports the immune system, protecting you from illness and helping you recover if you do become sick.

Suppress appetite and promote healthy bifidobacteria

Whey protein contains about 15-20% Glycomacropeptide. Dental research indicates that GMP prevents plaque build-up and tooth decay. GMP has also been shown to stimulate the synthesis and release of cholecystokinin (CCK) in the stomach. CCK is a chemical that tells your brain you are full, so it is a kind of appetite suppressant. By suppressing appetite, the GMP found in whey protein provides a built in weight management component not found in other protein sources. Still more studies show GMP has growth promoting activity for bifidobacteria (healthy gut flora), helps blood flow smoothly, improves skin cell activity and supports the immune system.

Immunoglobulins may support the immune system

The Immunoglobulin (Ig) fractions make up about 2-3% of whey and, as the name implies, imparts immunological activity to whey. Immunoglobulins encompass a group of proteins including IgG, IgM, IgA, and Secretory IgA, where Ig stands for “Immunoglobulin”. Infants receive immunoglobulins in breast milk imparting “passive maternal immunity” to the child which helps build the immune system. Studies suggest immunoglobulins may also support disease control in adults through similar mechanisms.

Helps fight infection

The Bovine Serum Albumin (BSA) whey fraction is high in essential amino acids and makes up about 2-5% of whey. Research shows that BSA helps infection-fighting white blood cells called T-cells, increasing their numbers. BSA also increases antioxidant activity. This increase has been shown to help prevent fats from oxidizing in the body, a key to maintaining healthy cholesterol levels. Another recent study indicates BSA may fight the incidence of Type 2 (adult onset) insulin dependent diabetes and possibly other auto-immune conditions.

Provides antimicrobial activity

Lactoferrin (Lf) is an iron binding protein fraction making up less than 1% of whey. The iron binding/chelating capacity of Lf gives it antimicrobial activity. By depriving microorganisms of iron, which is necessary for their growth, the organisms cannot continue to make us sick. This iron binding effect is antibacterial, antimicrobial and antiviral because all of these organisms require iron to flourish. There is data indicating that the ability of Lf to bind iron and take it away from bad organisms might also help transport it into our body for valuable health benefits. Recent research has focused on the biological activity of Lf and how it has benefits in fighting cancer, toxins, supporting the immune system, wound healing, and anti-inflammatory activity.

Fight plaque and cavities Lactoperoxidase (Lp) and Lysozyme (Lz) make up other fractions found in whey and consist of less than 1% of the protein. The main function of Lp and Lz is to prevent infection by acting as antimicrobial agents. With the ability to kill and prevent the growth of bacteria, Lp and Lz deal with a number of microorganisms but appear to leave biologically important proteins and enzymes alone. Dental research indicates Lp and Lz can fight plaque accumulation, gingivitis and cavities.

Whey protein also promote weight loss and fat loss.

A well educated lifestyle personal trainer and nutritionist must be able to understand the difference between whey protein.
