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.
