answer.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.
