Hi guys, I've heard a few people here mention they prefer whey isolate to whey concentrate. I'm aware of the cholesterol oxidization factor but is there any other reason? Are there many health benefits? Bodybuilder types constantly tell me that the ONLY reason to prefer isolate is lactose intolerance. Are they correct?

whey concentrate has casein which may not be very good for some people.
Plus it impedes absorption of good things like cocoa & blueberry polyphenols.

The difference of price between concentrate and isolate is important. A good concentrate such as Optimum Nutrition Gold  does impede absorption of cocoa?.

I think not. Whey and casein are separate protein fractions derived from milk. If there's casein in your whey, it's an impurity or contaminant.

concentrates by the nature of their production method are contaminated... i believe the highest quality concentrates are somewhere in the range of 80% and most definitely are contaminated with casein.

The lactose bothers me in standard whey isolates, and forget about concentrate. Even cross-flow microfiltration whey isolate (CFM) still has, for someone lactose-intolerant, a significant amount of lactose approaching 1 gram per 30g serving. The only whey protein that agrees with me is ion-exchange isolate, because it truly has almost zero lactose. If the manufacturer lists 0g sugar on a non-ion exchange whey protein, they are lying or "rounding down" like the food industry likes to do with trans fat.

Some fraction of it might be denatured? Since my choices are A) that or B) nothing, I don't really care.

Should I really be worried about caesin in whey concentrates?

[Recortes]

Well, given the big difference on price and that lactose is not a problem for me, I think I'll go the low cost version of concentrates. I'll put more cocoa to make sure I absorb something. I guess a study will come out in some years that shows that isolates are not so good , always happens in this business.

Lactose cause serious problems for you friend?
I'm fine with lactose, it has no effect on me that I can discern, but if isolate has additional benefits id have went with it.

Well, isolates are also better for health due to their lower fat content. The source of most (if not all) whey protein is not organic, and the milk fat is toxin/chemical/pesticide laden. If you want to minimize the hazards of consuming non-organic animal products, you want to reduce or eliminate fat content.

What about "plain old whey", no concentrate, no isolate?
