How much protein is necessary?

This article was very interesting. I did not know some of the protein we already intake account for moist of the protein we need. After working out you should take rote in shakes or some sort of protein to make sure you build healthy muscle, but you are right in the fact that you don't want to eat to much of it. In the long run, protein can be bad for you if you have to much because your body doesn't know what to do with it.
