The thing is that if a person is getting enough protein from real whole foods, then there is no need to supplement with protein powders. Bodybuilding and fitness magazines are the worst offenders for promoting protein supplements, they have to promote them because they are sponsored by nutritional supplement companies. This whole idea of post-workout protein shake has become a dogma and there are thousands of opinions about it. But is it really necessary ??.. Old school bodybuilders from 1940's, 50's and 60's didn't have fast digesting whey protein supplements and they build some amazing strong athletic bodies. Those guys had real strength. They got all their protein from meat, milk cheese, eggs and fish. Notice that all of these whole foods are slow digesting protein, and not fast absorbing protein like whey powders. People are always looking for some miracle pill or powder to give them fast results and increase their performance. It's doesn't work that way because human body is meant to live on real whole foods and not isolated nutrients.
