The fact about your whey protein

[big roid]

Whey protein isolate is the most pure and concentrated form of whey protein available. It contains 90% or more protein and very little fat and lactose. Whey protein concentrate has anywhere between 29% and 89% protein depending upon the product. As the protein level in whey protein concentrate decreases the amounts of fat and/or lactose usually increase. When whey protein is hydrolyzed the protein chains are broken down into smaller segments called "peptides". Hydrolyzed whey protein is still a high quality protein however, it is less likely to cause an allergic reaction than non-hydrolyzed whey protein. Individuals with lactose intolerance should select a pure whey protein isolate, which has less than 0.1 gram of lactose per tablespoon (20 grams). Individuals with lactose intolerance should avoid whey protein concentrates as they usually contain lactose and the amount can vary greatly from product to product.




Here are some of the differences between whey protein and soy protein.
Whey protein is a nutritionally complete protein. It contains bio-active ingredients, like immunoglobulins and lactoferrin, that help support the immune system. Athletes prefer whey protein to soy protein due to its rich abundance of branched chain amino acids and its quick absorption rate. These are important to help repair and rebuild muscles after a workout or competitive event. Whey protein has a fresh, neutral taste compared and will not change the taste of foods you add it to. Whey protein does not contain isoflavones or any other components with potential hormonal effects. The worse part about soy is the horrendous gas it causes plus it doesn't absorb as good. When you get gas from protein it's because it's not absorbing into your body. That means protein blends with the main ingredient (the first one listed on the label) should be isolate to get the best effects. If your protein has soy, egg or concentrate for the main ingredient your getting ripped! Especially if it's the soy or egg and the concentrate can vary in quality. Just something to think about when making your next purchase of Whey.

I agree with your comments about soy and also that lactose intolerant people should probably use isolate if they have a severe case. I disagree that anyone will get better results from isolate than concentrate. If you are getting adequate protein on a daily basis, then the iso. vs conc. debate will be meaningless.

Concentrate always causes worse bloating from gas. That means it's not absorbing as good. I've used just concentrate and just isolate to experiment before. Isolate wins anyday over concentrate.

In terms of results no one will ever notice a difference between isolate and concentrate.

I think however, it is important to include soy protien as a part of any diet. I use it at nite w/ skim milk because soy protien is a much slower disolving protien
