The older I get, the more I realize the importance of net absorption vs gross consumption, I believe that whey is much easier for an older body to use more completely. If I'm wrong it's not the end of the world - I actually prefer a good milk/banana/whey shake to a lot of common foods.
I was recently gifted a 2 lb tub of "Trutein" that a chick I know had bought as part of a new years resolution but couldn't stand the flavor. I thought it was the best I'd ever tasted and I've used these for years , it was peanut butter and man, it was delicious. Usually I just go with the Walmart brand and it works just fine.
