[Assessment of the human requirement for protein].

The results of investigations involving the participation of humans and literature sources on a comparative assessment of methods for determination and quantitative characterization of minimum, reliable and safe levels of protein allowances for young practically healthy males were compared. A reliable level of allowances for the caseine protein was found to comprise 9.0-9.2 g/day with reference to nitrogen. The optimal allowance of the same protein is 13.5-14.0 g/day calculated to the value of nitrogen.
