Protein – Which is Best? in journal of sports nutrition
I'd recently dropped whey protein isolate, because I suspected something in my shake mix was giving me trouble. It turned out to be everything except the whey protein powder.

It's an interesting article, like this information:

Whey Protein Isolate (WPI)
Isolates are the purest protein source available.
Whey protein isolates contain protein concentrations of 90% or higher. During the processing of whey protein isolate there is a significant removal of fat and lactose. As a result, individuals who are lactose intolerant can often safely take these products
(Geiser, 2003). Although the concentration of protein in this form of whey protein is the highest, it often contain proteins that have become denatured due to the manufacturing process. The denaturation of proteins involves breaking down their structure and losing peptide bonds.

I regard whey protein powder as the same as non-fat dry milk, which I drank plenty of as a child, with no lack of nutrition that I'm aware of. But now I'm alert to processed food and their different levels.
I still try to pick the least processed, but I'm supposed to start my day with lots of protein, and my custom whey smoothie is easier to digest. I love steak and eggs, but I can no longer eat the whole plate until my energy is back up again.
More protein, the better I feel. |
