They're in almost every energy bar, protein powder and enriched food these days. Here's why you should stay far away from isolated proteins (i.e. soy protein isolate, whey protein isolate, etc) and information on a much healthier alternative!

    If you have information you want to share , share it onsite not offsite. seems silly having to keep going offsite to read stuff.

    Sorry, I will always redirect to my blog as this forum doesn't allow for HTML editing within the text fields. I don't think an entire article would be pleasant to read in this format.

    I see that your source is a health expert... However for the life of me I can not find a study or scientific data to back up this claim. Infact, I see a decent amount of studies saying it can help cancer and such.

    Perhaps I'm wrong?

    Woah, bourbon vanilla flavoured?! Sign me up!! :laugh: Is the whey concentrate particularly more expensive than a whey isolate? I'm nearing the bottom of my container & in the market for a new one - wouldn't hurt to try!! :flowerforyou:

    Whey concentrate as far as I recall is the cheapest form of whey protein to make, it isn't as refined as isolate, slower acting in the body and harder to absorb. It also contains a higher fat and lactose count as opposed to isolate protein.
    Also the comment about lack of BCAA's in whey isolate is not true, by nature whey protein has one of the highest bcaa contents of most foods, and many companies add extra bcaa's into their protein blends anyway.

    Additionally as far as I know studies of whey protein concentrate or otherwise have not been linked to any documented side effects.

    Also, I had a look at Tera's whey, and cant even find an ingredient list...I wouldn't touch the stuff unless I have a clear breakdown of what goes into it.

    Unless hard evidence and studies can be provided to explain the benefit of concentrate over isolate except that of cost, I'll stick to my isolate mixture and worry more about the different gums, colourings, flavourings etc being put into the protein powders as opposed to the whey breakdown itself.
