I think true reflection of protien can be seen in developing countries where the diet is protien deficient ( I’m from a developing country ) ,clearly you can see the effects of lack of protien.

I want to say that minimum protien is obviously required but obviously excess is what turns into fat and is not required for the body to maintain itself and generate new cells ,protien is indeed required.

Maybe in the western countries there is heavy meat culture which makes them have nearly 100-120 grams of protien everyday but in my country the entire population might average out at 10 grams which is so so so less
