One thing that continues to confound me is the difference between the popularity of whey protein is (thanks in large part to yours truly) and how there is confusion about this popular supplement . Why are men so insecure, the whey? I concluded that complement some of the misleading advertising by some unscrupulous companies, little research articles prepared by self-styled “guru” types, and the fact that whey is indeed a protein complex. In this article I will try everything at once and for all. . . Lift up the valley of secrecy cast off the myths and break the hyperbole surrounding this ultra popular supplement.

Over time you will read through this article, you know what to do regarding the differences in whey, such as concentrates vs. isolates, micro filtered vs. ion exchange, and many Other answers to questions that seem to exist, no matter how such hard-Guy writers like myself have tried to give up all the myths and misinformation / disinformation surrounding whey. Read this article carefully, put it in memory, experts and whey in the gym and you surprise your friends at the next barbecue if whey becomes a topic (in this case, you are some boring cookouts GB !).

What is whey?

If we love, we talk about whey referring to a complex element of protein, lactose, fat and minerals. Protein is the best known component of whey and is composed of several sub-fractions of smaller proteins as follows: beta-lactoglobulin, alpha-lactalbumin, immunoglobulins (IgG), glycomacropeptides, bovine serum albumin ( BSA) and minor peptides such as lactoperoxidase, lysozyme and lactoferrin. Each sub-fractions in whey has its own unique biological properties.

Until recently, separating these subfractions on a large scale was impossible or too expensive for anything other than scientific purposes. modern filtering technology has improved over the last ten years as part of the company highly bioactive peptides such as lactoferrin and lactoperoxidase-from whey separate.

Some of these sub-fractions that are found in very small quantities in cow’s milk, usually in less than one percent. For example, although one sub-fraction of the most promising for the prevention of various diseases, improving immunity and overall health, lactoferrin 0th represents about 5% or less of the protein cow’s milk whey (milk protein that man, up to 15% lactoferrin). In recent decades, whey protein powders have several generations of low protein concentrates to very high protein isolates.

What is the benefit about whey?

Whey protein has become a basic supplement for most bodybuilders and other athletes, and for good reason: It is a large protein to a number of advantages. Whey has more recently taken on groups anti-aging/longevity-minded too.

A growing number of studies have shown, the whey may potentially reduce cancer rates, the fight against HIV improve immunity, reduce stress and lower cortisol, increase brain serotonin levels, improving function liver lower in those who suffer from certain forms of hepatitis, high blood pressure and improve performance, just to name a few potential applications of sports medicine. Whey also rated very high biological and exceptionally high Branch Chain Amino Acid (BCAA) content.

One of the main effects of whey is its ability to increase the apparent glutathione (GSH). The importance of GSH for the proper functioning of the immune system can not be overestimated. GSH is the most important antioxidant soluble in water present in the body.

The concentration of intracellular GSH is directly related to lymphocytes (an important component of the immune system) reactivity to a challenge, the intracellular GSH suggests, are a means to modulate the immune system. GSH is a tripeptide-up of amino acids L-cysteine, L-glutamine and glycine. Of the three, cysteine is the main source of free thiol group of GSH and is a limiting factor in GSH synthesis (although the effect of whey on GSH is more complex than just their cysteine content).

Since GSH is known to be essential to immunity, oxidative stress, and general welfare, and because a decrease of GSH are associated with a long list of illnesses, whey has a place in the nutrition program, anyone . Reduced GSH is also training syndrome (OTS) in athletes, so whey may very well be applied to prevent or at least mitigate associated OTS. Directly with the athletes, some recent studies suggest whey may have direct effects on performance and muscle mass, but this research is primarily at the most. Some studies have shown oxidative stress contributes to muscle fatigue while increasing levels of GSH may allow you to train longer and harder than some of the most recent data point to it.

Different types of whey

Most of the confusion surrounding whey appears to be in understanding the different types of whey: concentrates, isolates, ion exchange, and others. In the following sections, I will try everything clear to the reader.

whey protein concentrates:

First generation whey protein powders contain as low as 30-40% protein and large amounts of lactose, fat and denatured proteins. They are classified as whey concentrate and are mainly used in the food industry for baking and other purposes. Modern now concentrates contain 70-80% proteins high with reduced amounts of lactose. This is achieved by ultrafiltration process reached the lactose removed, the result of the concentration of proteins and lipids in the finished product. Although many companies have invested heavily in marketing isolates maligned, concentrated well done is always a source of high quality whey protein, even if it contains more lactose, ash, and then isolate the fat.

The advantages and disadvantages of the isolates, micro filtered vs. ion exchange and debate

Whey Protein Isolate (WPI included) in general as much as 90-96% protein. Research has shown that whey proteins are denatured in their natural state (native conformation IE) biological activity. Treatment of whey proteins, lactose, fats, etc., no need to withdraw their biological activity, special attention by the manufacturer. Conservation of natural undenatured state of protein is essential for its anti-cancer activity and immune modulation. The protein is processed at low temperature and / or conditions of weak acid, not to denature “the protein. IPG contain more than 90% protein with minimal lactose and virtually no fat.

The advantage of a good WPI is that it contains more protein and less fat, lactose, and ash than concentrates on a gram for gram basis. However, it should be clear to the reader today is that whey is far more complicated than simple protein content and protein content in itself to use by far the most important factor in the determination of whey. For example, ion exchange has isolated the protein most apparent of all.

Isolate the power, he is the best choice for you? No, but many companies will grow as the holy grail of whey. Ion exchange is focused by the plug and run it through what is an ion exchange column has been called an ion exchange “whey isolate.” Sounds pretty fancy, but there are serious drawbacks to this method. As mentioned above, is the complex protein-protein whey numerous sub-group of peptides that have their own impact on health and immunity. Some of these sub-fractions were found only in very small quantities. The truth is that really what is ultimately sub-fractions of whey proteins are unique, it is.
