The United States (US) recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram body weight per day (g/kg/d). The International Society of Sports Nutrition (ISSN) recently recommended an intake of 1.4-2.0 g/kg/d whereas the United States and Canadian Dietetic Association typically recommend a lower range of 1.2 to 1.7 g/kg/d. It is clear that the US RDA for protein is grossly inadequate for exercising individuals; thus, athletes are typically advised to consume twice the RDA. This falls within the range commonly recommended by academic societies. The effect of protein consumption that exceeds these aforementioned guidelines is not entirely known. This review examines the current literature as it pertains to the influence of very high protein intakes in trained individuals (i.e., humans). It is the scientific opinion of the author that athletes should consume at least 2.2 g/kg/d of protein.
美国（US）建议的蛋白质膳食 allowance（RDA）为每天每公斤体重 0.8 克（g/kg/d）。国际运动营养学会（ISSN）最近建议摄入量为 1.4-2.0 g/kg/d，而美国和加拿大饮食协会通常建议较低的范围为 1.2 到 1.7 g/kg/d。很明显，美国的蛋白质 RDA 对于锻炼的人来说是严重不足的；因此，运动员通常被建议摄入两倍的 RDA。这在学术团体通常建议的范围内。超过上述标准的蛋白质摄入量的影响并不完全清楚。这篇综述检查了目前与训练有素的个体（即人类）中非常高的蛋白质摄入量有关的文献。作者的科学观点是，运动员应该每天至少摄入 2.2 克/公斤的蛋白质。
