在19名年轻男性和10名年轻女性（年龄分别为30 +/- 5岁和27 +/- 4岁）中，研究了蛋白质摄取量（分别占总能量摄取量的12%和21%，日粮A和日粮B）对氮平衡和全身蛋白质周转（PT）的影响。在年轻人中，饮食A期间的平均氮平衡接近于零，而饮食B期间的平均氮平衡为正。在年轻人中，饮食B期间的PT明显高于饮食A。如上所述，在老年受试者中也可见到这一点。从目前的数据与先前在老年受试者中获得的数据进行比较，可以得出结论，在饮食a期间，年轻人的PT率高于老年受试者。在饮食B期间，年轻男性的PT与老年男性的PT相当，而年轻女性的PT率仍然高于老年女性（即使对身体成分的差异进行了修正）。
The effect of the amount of protein intake (12% and 21% of total energy intake, diet A and diet B, respectively) on nitrogen balance and whole-body protein turnover (PT) was measured in 19 young men and 10 young women (aged 30 +/- 5 and 27 +/- 4 y, respectively). In young adults, mean nitrogen balance was approximately zero during diet A whereas it was positive during diet B. In young adults, PT was significantly higher during diet B in comparison with diet A. This was also seen in elderly subjects, as described before. From a comparison of the current data with the data previously obtained in elderly subjects it can be concluded that during diet A young adults had PT rates higher than those of elderly subjects. During diet B, PT of young men was comparable with the PT of elderly men whereas young women still had higher PT rates than elderly women (even when corrections were made for differences in body composition).
