关于夏季对蛋白质的需要量的研究是用14～17岁健康少年及25～30岁的成年人进行的。当食品中含蛋白质96.8克(其中动物性蛋白质34.4克),脂肪76.0克,碳水化合物568克及总热量为3429大卡时,受试者所得的蛋白质保障的指数是低的。在食谱中补加脱脂奶粉后所有的受试者的氮平衡增长到4.5克,蛋白质的吸收有了改善、氮潴留有了提高。因此,少年的蛋白质需要量为每公斤体重2.4克,成年人为1.8～2.0克。同时对少年及成
The study of protein requirements in summer was conducted with healthy juveniles aged 14-17 and adults aged 25-30. When the food contained 96.8 grams of protein (including 34.4 grams of animal protein), 76.0 grams of fat, 568 grams of carbohydrates and a total calorie of 3429 calories, the index of protein protection obtained by the subject was low. Nitrogen balance increased to 4.5 grams in all subjects after supplementation with skim milk in the diet, protein absorption improved, and nitrogen retention improved. Therefore, the juvenile protein requirement of 2.4 grams per kilogram of body weight, adult 1.8 to 2.0 grams. At the same time to juvenile and into
