Whey protein : Supplement Reviews

Whey protein is a pure, natural, high quality protein from cow's milk. It is a rich source of the essential amino acids needed on a daily basis by the body. In its purest form, as whey protein isolate, it contains little to no fat, lactose or cholesterol . It provides the body with the necessary building blocks to produce amino acids that are used for building muscle tissue. Whey protein contains the perfect combination of overall amino acid makeup and in right concentrations for optimal performance in the body. Both hormonal and cellular responses enhances with supplementation of whey protein. It has the benefits on immune system of the body too. Whey protein plays a role as an antioxidant and helps support a health immune system. Consistent whey protein intake coupled with exercise results in consistent muscle building.

Benefits:

Whey protein is a naturally complete protein, which means that it contains all the essential amino acids required in the daily diet. It is the ideal combination of amino acids to help improve body composition and enhance athletic performance
Whey protein is the rich source of amino acids which metabolises direct in the muscle tissue and are the first ones used during the exercise.
Whey protein provides the body with amino acids which replenish depleted levels and start repairing and rebuilding lean muscle tissue.
Whey protein is an excellent source of the essential amino acid, leucine. Leucine is important for athletes as it has a role in promoting muscle protein synthesis and muscle growth.
Whey protein is a soluble, easy to digest protein and is efficiently absorbed into the body. It is often referred to as a "fast" protein for its ability to quickly provide nourishment to muscles.
Whey protein isolate is pure protein with little to no fat or carbohydrates. It is a perfect complement to any low carbohydrate diet plan.
Hypertension is the main cause of heart disease and strokes. Whey protein helps in fight against hypertension.
It also reduces cholesterol level
Whey protein is a good protein choice for cancer patients as it is very easy to digest and very gentle to the system.
Whey protein is good choice for diabetic patients.
Whey protein initiates the growth of new skin during the healing process.

It reduces stress and lower cortisol
It increases brain serotonin levels
It improves liver function.
It reduces blood pressure and improve performance.

Whey isolate and concentrate:

Comparing these both, whey protein is more expensive than concentrate because of its high quality, and it has higher biological value. Whey protein isolate contains more protein with less fat and lactose per serving. Isolate contains 90-98% protein while whey concentrate contains 70-85%. Whey protein isolate is the highest yield of protein available which comes from milk. Because of its chemical properties, whey protein is the easiest to absorb into the muscles. With its high concentration whey protein isolate is the best to use. Whey protein isolate has the immune boosting properties. It is better to use whey protein concentrate with some isolate blended in it.

Side-effects:

People who are allergic to diary products can react to whey proteins and therefore should avoid it. Long term and excessive intake are associated with deteriorating kidney function and osteoporosis. There can be development of diabeted in children

Whey protein and cancer:

Several studies have been done on animals in regard of cancer causing chemicals to see what effects whey protein concentrate has on cancer prevention or treatment.

Rats were given various proteins and then carcinogen dimethylhydrazine. Rats which were given whey protein concentrate showed fewer tumors and a reduced area of tumors. Whey protein concentrate inhibited the growth of breast cancer cells at low concentrations. Cancer patients showed a regression in some pateint’s tumors when they were given whey protein concentrate at 30 grams per day.

The two basic methods used to process whey protein are

Microfiltration and ultrafiltartion
Ionexchange

Microfiltrartion process gives a lower concentration of proteins and amino acids, where natural ceramic filters are used to separate whey protein from protein solution. Undesirable components such as fat and lactose are filtered out. The particles are separated based on their molecular size and shape.

The advantage of this processing methods are:

It preserved protein microfractions.
It gives amino acid profile.
It does not damage the many immune boosting components
Microfiltrations has highest level of undenatured protein available.
Separation of protein without the use of heat and chemicals.

Ion exchange whey protein:

It involves separating proteins based on their electrical charge. Two chemicals are used to achieve this: hydrochloric acid and sodium hydroxide. The electrical charge on the proteins attaches them to the resins in the reaction vessel. Its benefit is that its end product has less fat and lactose
