Well, everyone is entitled to his/her opinion and I respect that. As for your questions, you gotta take it up with all the authors/scientists listed since they are all in compliance with what I posted. I'm confident all your questions can be answered by someone with a degree/PhD. It wasn't hard for me to find the proof. Check it out for yourself and draw your own conclusions. There was alot of times where I was proved wrong and I'm a better man for it. (Not taking away from your perspective) But, from a bodybuilders perspective, the above is reason enough, at least for me, to continue my 40-50 grams per serving of protein without concern.
As for some of your examples of cougars and them eating meat and insects, I think you're getting defensive. They have a genetic limit as do we all. That doesn't have anything to do with the amount of protein humans can eat per serving.
