title: [Advances on the level of reference nutrient intake of protein and amino acid].
abstract: The value of requirement of protein in adult is 0.66g/(kg x d), as is suggested by FAO in 1957. Through the detail discusses repeated by many experts in the world, FAO/WHO/UNU suggested that RNI of protein and amino acid was different for different age groups, based on nitrogen balance method and factorial method. But there were opposited opinions, based on the same methods, the values that some research groups in America and England got were different from that of FAO/WHO/UNU. The requirements of specific indispensable amino acid that Vernon. R. Young had got by using the stable isotope technique were 2 - 3 times higher than that of FAO/WHO/UNU.
