蛋白质需要量比热量需要量更受社会、经济等重要因素的影响。例如18岁的男子,捷克斯洛伐克为115g,比阿根廷的35g高3倍以上。这是在热量需要量中没有看到的现象,无论如何也难以得出科学的结论。另外,关于FAO/WHO新的蛋白质需要量,Scrimshow博士的演讲中谈到:从1974年的0.57g/kg增加到1982年的0.75g/kg,而且标准蛋白质的氨基酸模式变为:异亮氨酸189(mg/gN),苏氨酸250、亮氨酸406、赖氨酸344、蛋氨酸196、苯丙氨酸313、色氨酸63、缬氨酸280。蛋白质需要量与热量需要量一样,成年值只表示普通劳动的需要量。在有些国家里,因劳动强度不同,需要量差别很大。由此看来需要量也有论功行偿的意思。年龄表示到该
Protein requirements than the amount of calories more affected by social, economic and other important factors. For example, the 18-year-old man, Czechoslovakia is 115g, more than three times higher than 35g in Argentina. This is a phenomenon not seen in the caloric requirement, and it is hard to draw a scientific conclusion anyway. In addition, regarding the new protein requirement of FAO / WHO, Dr. Scrimshow’s speech mentioned that from 0.57g / kg in 1974 to 0.75g / kg in 1982, and the amino acid pattern of the standard protein becomes: isoleucine Acid 189 (mg / gN), Threonine 250, Leucine 406, Lysine 344, Methionine 196, Phenylalanine 313, Tryptophan 63, Valine 280. The protein requirement is the same as the calorie requirement, and the adult value only represents the amount of normal labor required. In some countries, the demand varies greatly due to different levels of labor intensity. It seems that the amount of demand is also the meaning of compensation. Age said to that
