First off, I think protein ingestion as a whole is important but I feel too many people go overboard in worrying about it. If the average person is eating 10 to 20% while the active person is getting as high as 30% of Kcal/day in protein they are probably getting enough (based on other macro's and calories). My point was mostly that the studies looking at the increases in the anabolic environment with pre and post protein show pretty conclusively that these are very very important. As far as how much, the studies mostly used a mixture of 6g EAA (Essential Amino Acids) not a protein mixture per se. Now I just posted what I think is a good rule of thumb at my forum so I'm just copying it over here. Now this isn't exact by any stretch and others may use/recommend differing amounts or substitutes this is just an estimate, nothing more.
