Just the Facts: Whey Protein Concentrate!

Tired of reading articles promoting whey protein concentrate, promising you the world, but not explaining the science behind it? If you would rather get the hard facts on whey protein concentrate, this article is perfect for you. Read on to learn what you can find in whey protein and how it affects your physical fitness.

What Is the Composition of Whey Protein?

Those who have read about whey protein concentrate, and whey protein in general, already know that there are quite a few components making up whey protein supplements. In most whey protein concentrate supplements, and other whey protein powders, you will find substances such as alpha-lactoglobulin, beta-lactoglobulin, bovine serum albumin and immunoglobulins.

Whey protein also consists of smaller components, which are often not mentioned because athletes always look for very specific ingredients, some of which were already mentioned above. In addition to the compounds mentioned earlier, whey protein also contains iron binding proteins, calcium, potassium, sodium, phosphorous, vitamins (A, C, B1, B2, B3, B5, B12), folic acid and biotin. Therefore, athletes can count on numerous health benefits as well, at least if they decide to use a whey protein supplement.

What Makes Whey Protein Effective Where Composition Is Concerned?

A whey protein supplement is effective because of the combination of nutrients inside. First of all, a whey protein powder contains a great balance of essential amino acids, but also peptides that contribute to better fitness.

In addition to the essential amino acids and peptides, whey protein is also a source of sulphur amino acids, more specifically methionine and cysteine. One of these amino acids has extra importance, because cysteine is used during the synthesis of a powerful antioxidant known as glutathione.

Whey protein powders are also a fantastic source of branched chain amino acids. Branched chain amino acids refer to leucine, isoleucine and valine. Each of these branched chain amino acids contributes to your health, but leucine in particular is interesting for fitness fanatics, because leucine plays an important role in protein synthesis.

Inside whey protein, there is also a substance called glutamine, a hydrophilic amino acid that is actually a part of most types of proteins. In other words, without glutamine, muscle growth and muscle repair would not be possible at all!

What Does the Composition of Whey Protein Do for Weight Loss?

The calcium inside whey protein directly contributes to weight loss, because calcium decreases the accumulation of fat inside the body. By decreasing fat accumulation, calcium can therefore accelerate the speed in which you lose weight.

There is a certain type of mechanism in the human body that will promote the storage of fats in the body. The key component in this mechanism is the parathyroid hormone, a hormone that immediately reacts to a low calcium diet and promotes the storage of fat to counter it. If you have enough calcium in your diet, the creation of the parathyroid hormone will be stopped, which means it will also stop fat storage and increase fat breakdown.

What Does the Composition of Whey Protein Do for Digestion?

Whey protein contains lactose, except in whey protein concentrate, a version of whey protein where lactose is removed. When whey protein powder is consumed, the lactose in the composition of the supplement is broken down into substances called galacto-oligosaccharides. These galacto-oligosaccharides are used by gut bacteria, which can be found in the intestines. It is these bacteria that help digestion and reduce the chances of digestive distress.

What Do the Antioxidants in Whey Protein Used?

The antioxidant, glutathione, is more important than people would first think. The antioxidant is used during the detoxification process, but athletes often miss this antioxidant because of intense exercise. Studies have shown that glutathione levels decrease when training, so replenishing glutathione after training will be essential to get fitter.

Research has indicated that whey protein is able to replenish glutathione levels much better than casein protein powders. The results of this study were especially clear in areas such as the heart tissues and the liver tissues.

Another study also indicated that the use of whey protein could fight free radicals. When treating cells with whey protein isolate, results showed that the supplement increased the intracellular GSH by a whopping 64% and protected the cells against free radicals. Researchers believe that these results prove the role of whey protein powders in GSH synthesis.

What Explains the Link Between Whey Protein, Insulin and Supplement Use?

The use of whey protein is closely linked to insulin levels. After intense training, your body is very sensitive to insulin. For that reason, the body starts to transport carbohydrates and proteins to the muscle cells, but not to the fat cells. An athlete’s sensitivity to insulin will decline slowly over a period of time, which is two hours for most.

Considering the quick way in which whey protein is digested, it is best to take the supplement after training, more specifically when the body is more sensitive to insulin. By taking whey protein post-training, athletes can take advantage of that insulin effect and get protein to their muscles quicker and more effectively.

Does the Use of Whey Protein Have Any Disadvantages?

There are some risks connected to the use of whey protein, so athletes should read through all these potential risks before they decide to use whey protein supplements.

First of all, there is a risk of an allergic reaction to the supplement, as is the case with most protein supplements such as soy protein, casein and egg-based proteins. If you are prone to certain food allergies, please contact a health professional before you decide to use any form of supplement.

Athletes suffering from diabetes should also consult a health professional or nutritionist before they decide to go ahead with a supplement regime. Considering the role of insulin in the absorption of whey protein, the use of the supplement could have a negative effect on the athlete.

An excessive intake of protein can cause kidney damage, so it is essential to check your daily protein intake as well; this so it does not exceed the daily recommended amount. If you are unsure, please contact a health professional or a nutritionist who can help you work it out and give you some valuable advice.
