What's the difference between whey isolates and blend?

mandypumpkin · 01-13-2005, 03:08 PM

I'm looking on alltheywhey.com and I can't figure out the difference. I know that the isolate has the following (shortened version)

Calories 102
Total Fat < 1g < 2%
Saturated Fat <1 g 2%
Total Carbs 1 g < 1%
Dietary Fiber 0 g 0%
Lactose < .6 g
Potein 24 g 48%

and the whey blend has this:

Calories 108
Total Fat 1 g 2%
Saturated Fat <1 g 2%
Total Carbs 2 g 1%
Dietary Fiber 0 g 0%
Protein 22 g 44%

The only difference I really see is that the whey blend has a few more cals and two less grams of protien, and one less carb. Does that really matter? The blend is less expensive....

Any comments?

Wow....I didn't realize there were so many choices. Thanks for the link.
By the way, do you have any recommendations on which to use?

nikegurl · 01-13-2005, 03:23 PM

what you use depends on when you're using it (post workout or as a meal replacement at another time etc.) definitely check out the article IanDaniel linked. it's a good one.

mandypumpkin · 01-13-2005, 03:30 PM

I'll be using it at different times, but my main use will be post workout. I might use it for breakfast with other whole foods because I get reallllly tired of eggs.

nikegurl · 01-13-2005, 03:38 PM

post workout you want a fast digesting protein (whey isolate) at other times you'd be better with a slower digesting protein. you can buy 2 types or you can go with the whey isolate and add a fat source for the non post workout times you use it (i.e. scoop of natural peanut butter) to slow digestion.

a "true" blended protein contains a whey fraction, egg albumin and caesin

machinehead · 01-14-2005, 06:09 AM

one of the important thing about them:

concentrate whey - BV 104
isolate whey - BV 159

Ummmm...what does BV mean?

Great! Thanks a bunch.

BV=biological value. THe higher the value the better. Realistically though, most everyone agrees that anything over 100 is just a number and that you can not get over 100. Here is an example...........

A measurement of protein quality expressing the rate of efficiency with which protein is used for growth.

Egg contains the highest quality food protein known. It is so nearly perfect, in fact, that egg protein is often the standard by which all other proteins are judged. Based on the essential amino acids it provides, egg protein is second only to mother's milk for human nutrition. On a scale with 100 representing top efficiency, these are the biological values of proteins in several foods.* -see Nutrient, Protein

Whole egg 93.7
Milk 84.5
Fish 76.0
Beef 74.3
Soybeans 72.8
Rice, polished 64.0
Wheat, whole 64.0
Corn 60.0
Beans, dry 58.0

Example : you have a 6 oz ground sirloin burger which has 62 grams of protein . the BV of beef is 74.3. So 62 x .74 = 45.88. that burger supplys you with almost 46 grams of protein

mandypumpkin · 01-14-2005, 09:14 AM

Okay....let me get this straight. Since concentrate whey has a BV of 104 and
isolate whey has a BV of 159, that means that I'll use a greater % of the isolate whey. But, since they are both over 100, does that mean that I can do the formula as stated by LAM?

Example : you have a 6 oz ground sirloin burger which has 62 grams of protein . the BV of beef is 74.3. So 62 x .74 = 45.88. that burger supplys you with almost 46 grams of protein

My Question: You have 1 scoop of isolate whey with 22 g protein. Does that mean that I can do this? 22 x 1.59 = 34.98 g protein? Or does that only apply to food?

LAM · 01-14-2005, 09:26 AM

the BV score that whey is given is bogus. in the "real world" whey has a BV of 100. which means 100% of the protein is available for maintenance and or growth

**dg806** · 01-14-2005, 09:27 AM

Protein powder is already "broken down". So it is all available. Food has to be processed by the body. You can't end up with more than you started with.

That's what I thought....thanks for clarifying!
