Whey proteins

February 17, 2010

Since some of you are questioning about whey thought I'd just share that not all

whey protein is the same. For this group you do not want a concentrate and if

your protein powder will be cheap -but it will be a concentrate. With the

concentrate you get less protein -and it will not be casein free and is not as

easily digestible by the body. Isolate protein is more expensive -probably 2 to

3 times more expensive but in my opinion as someone who has drank protein shakes

for years -worth it. I can share that while my friends and I who are health and

fitness conscious for years have had the best of the best protein powders -in

our opinion nothing compares for some reason to the nutriiveda. Nutriiveda is

not just a pharmaceutical grade of whey isolate protein -it also contains a

synergistic blend of botanicals and nutrients formulated and endorsed by some of

the top medical doctors in the world. Just like fish oils you can find other

brands than the brands we know that work- but as you learn more you learn that

not all is the same as it appears.

Below is an article about whey protein from a body builder's standpoint. I know

I had found one once before that was more scientific to compare different whey

proteins -but for now this will do. It is clear to me that the whey protein

powder talked about here is a concentrate not an isolate. Concentrate is not

casein free amongst other things -and it will be the easiest and cheapest form

to find. As this body building expert advices -search for the highest quality

whey isolate protein -you'll pay much more but -it's worth it.

The scoop on whey protein

What is available and what is right for you

Protein, protein everywhere, but how do you know if you are getting high quality

protein? There are so many companies selling protein it is confusing to know

what's good and what's not. Let's put it into simple terms and make it

understandable so you can buy with confidence. The type of protein in a product

definitely determines the price. When it comes to proteins whey is king, and

there are several different types. Let's look at the three types of whey

available and understand what makes each type unique.

Whey protein can be broken into three classes: hydrolysates, isolates and

concentrates. Hydrolysates are the most expensive form of whey, followed by

isolates and lastly concentrates. Concentrates are the least refined while

hydrolysates are the most refined. Whey it comes from the milk of cows. The whey

protein in your favorite protein powder can come from various types of

manufacturing processes. Often whey is created during the cheese making process,

which means it has been treated with harsh acids to separate the whey from the

casein used for making cheese. Whey can also come from whole milk being

separated specifically for the purpose of producing high quality whey and high

quality casein. Buyers beware, not all whey is created equal!

The difference between the three types of whey proteins involves protein, fat

and carbohydrate content and degree of hydrolysis. Whey concentrate generally

has a protein content of 30 to 80 percent with the rest being lactose, fat and

minerals. A whey isolate generally as a protein content between 90 and 96

percent with less lactose, fat and minerals than a concentrate. Whey hydrolysate

is a further processing of whey isolate by chemically or enzymatically breaking

down the long protein chains to various degrees. The higher the degree or

percentage of hydrolysis, the more broken down the whey protein isolate. The

reason for hydrolysates is to make it easier and more rapidly absorbing than

whey concentrate or isolate. With hydrolysis comes bad taste. The more

hydrolysed a protein, the worse it is going to taste and the more expensive it

will be. Whey isolate is the second most expensive and the least expensive is

whey protein concentrate.

Where your whey comes from is very important in relation to the quality of the

whey protein powder in your packet or jug. The best source of whey comes from

whole milk, not an offshoot of cheese production. If whey is extracted from

whole milk through a filtration process it will generally be higher quality. The

filtration process also matters, and so do the temperature and other chemicals

used during the processing. The processing techniques are important to

understand because this affects something called biologically active whey

protein fractions. You want to protect these valuable whey fractions so you can

get maximum benefit from them in your supplements. These health promoting whey

fractions include alpha-lactalbumin, beta-lactoglobulin, glycomacropeptides,

lactoferrin, lactoperoxidase, immunoglobulins, lysozymes, bovine serum albumin,

etc. Whey fractions can improve immune function, enhance recovery, improve

mineral absorption and play a major role in improving your physical health and

performance.

There are many different filtration processes designed to preserve the valuable

fractions found in whey. These processes go by names like, microfiltration,

ultrafiltration, nanofiltration, reverse osmosis filtration and dynamic membrane

filtration, to name a few. The objective here is to preserve as many of the

native protein fractions as possible so that when you mix up your protein shake

you get all the benefits of the whey fractions. If the processing damages or

destroys any of these valuable protein fractions you aren't getting maximum the

benefit from your whey.

Most protein powders today are made from blends of whey protein concentrate,

isolate and hydrolysate combined with soy and egg proteins.

Keep in mind that an excellent quality whey protein is VERY expensive. With all

of the trash protein out there at low, low prices the consumer just doesn't

understand the benefit of expensive high quality whey protein nor why they

should pay more for it. Most of the proteins out on the market are not produced

from the highest quality whey protein isolate available due to the cost.

Generally you will find a blend of whey types with casein, egg and even soy.

While casein, egg and soy are great proteins in their own right, they do not

contain the bioactive fractions found in high quality whey. Soy provides high

quality protein, and can even deliver valuable isoflavones, but soy does not

contain the whey fractions. Casein is often combined with whey to slow down the

whey and " time release " the protein. This " time released " protein has its

benefits for meal replacement products and night time products. However, for

post workout delivery, go for a high quality bioactive whey protein isolate.

If you want the most versatile, highest quality, health-promoting protein

available then you should look no further than a delicately filtered, gently

processed, whole milk sourced, high- quality whey protein isolate. This product

will be low in fat and lactose and deliver at least 90 to 96 percent protein per

scoop. Make no mistake, this type of high-quality protein will cost you, but a

high-quality whey will allow you to train harder and maximize your gains.

High-quality concentrate can also be valuable if you don't mind a little more

carbohydrate and fat content. The high quality whey concentrates are often a

better buy due to their lower price, and if processed correctly can have a very

high percentage of the valuable bioactive whey fractions.

If you can't determine the type or quality of whey used in your favorite

protein, contact the company who makes it. The company should be able to tell

you where they source their whey and how it is processed. If they can't then you

need to find another company for your whey protein!

As always, if you have questions e-mail me at editor@.... Until next

month; train smart, eat healthy, supplement wisely, rest well.

I completely agree. We selected ours after consulting with his pediatrician and

nutrishionist. He doesn't have any food allergies, so it made it a little

easier. Also, the can we bought is only 15 full scoops, so only 1/2 month or

less supply for those on mutiple scoops. He has his annual IEP in the coming

weeks, and then tracks out, so we thought it best to wait to start the NV, and

since we had a little time between, and it wouldn't cause any ill effects, to

try just the whey to see what the differences were we we did the NV. Not trying

to stir up controversy....just thought we would post for the purposes of

research.
