Whey Protein Isolate: What do we really know?

Posted Feb 19 2011 8:25am

This whole argument between science and religion has raged on for decades now. And despite the fact that religion is now waging a losing battle, scientists everywhere have to accept the fact that we still "don't know" as much as we would like to.

Yes, if that hasn't been obvious enough… that's the real deal here.

Science and industrialization has gone hand in hand, and along the way, there have been realizations that have dawned on mankind especially in regards to what they consider valuable or not.

And while there are a bazillion examples to justify this claim of mine, there is one such  product that comes to mind when it comes to the matters of health and fitness.

And it has always been derived from the now-dreaded dairy product… cheese! The very product that little Miss Muffet was making a meal until the spider scared the poor creature away.

Yes, we're talking about whey…

Whey: From By-product to superfood

Whey was considered to be a waste by-product until scientists and experts in the medical and fitness community realized what an excellent source of protein this product is for anyone who is interested in building a great body or is an athlete at the highest level.

Apparently, this by-product is one of the best sources and is just as good as the much-acclaimed soy products since it is able to provide protein that can be used to generate all the essential amino acids that the body cannot produce by itself.

And if you don't know already, whey is actually the liquid portion that remains after milk is curdled and strained, and in most cases, its primary source is being a by-product when cheese is produced commercially.

From a scientific standpoint, there are three forms of whey these days such as the concentrate, hydrolysate and its purest form known as the isolate.

Whey Protein Isolate

Since the other two forms aren't as pure as its isolate version, there are several ways to produce whey protein isolate, among which the cross-flow filtration comes up trumps over the method of producing it using the Ion exchange.

While both methods seek to produce the highest amount of protein, the latter isn't able to capture the sub-fraction peptides that offer the most benefits to its consumers along with the protein, and which is why health experts consider the former method to be the best.

Since, in this form, whey protein isolate contains almost 90 to 96 % protein, you can imagine what this can do for people who want to build mass safely while also not necessarily being too difficult to consume, thanks to its milky taste.

Benefits of Whey Protein Isolate

The bottomline is that there are several benefits that include the reduction of LDL cholesterol to having a high Biological value (the amount of protein that will be absorbed as a whole) as well as supporting one's immune system and decreasing soreness after training.

In Closing

No matter how you look at it, whey protein has found its place in the health community, and one can only wonder what the future holds when it comes to waste by-products turning into superfoods…
