The protein supply of 2--14 year old children in their families is reported. The food intake was measured with the precise weighing method. The protein intake amounts to 38 +/- 7 g/day (2.3 g/kg/day) for the 2--3 year old boys, 69 +/- 10 g/day (1.8 g/kg/day) for the 12--14 year old boys. The protein intake of girls, absolute and per kg bodyweight, averages 10% less. Protein constitutes 11--12% of the energy supply, 2/3 originating from animal foodstuffs, 1/3 from vegetable foodstuffs. Milk and dairy products have a proportion of 34--41%, meat and meat products of 20%. The protein distribution among the different meals is shown. After 25 days almost all the children reach their mean value for their individual protein intake with a standard error of +/- 5%. In each age group 54--59% of the children differ in their mean protein intake from each other. The protein supply recommended for a certain age group should not be obligatory for the individual child. The protein supply of the various age groups and of the individual child is discussed.
报告了2至14岁儿童家庭中的蛋白质供应情况。采用精确称重法测量食物摄入量。2至3岁男孩的蛋白质摄入量为38±7克/天（2.3克/千克/天），12至14岁男孩为69±10克/天（1.8克/千克/天）。女孩的蛋白质摄入量，无论是绝对量还是每千克体重的摄入量，平均少10%。蛋白质占能量供应的11%至12%，其中三分之二来自动物性食物，三分之一来自植物性食物。牛奶及奶制品占比34%至41%，肉类及肉制品占20%。显示了不同餐次间的蛋白质分配情况。25天后，几乎所有儿童的个体蛋白质摄入量均达到其平均值，标准误差为±5%。在每个年龄组中，54%至59%的儿童平均蛋白质摄入量彼此不同。针对特定年龄组推荐的蛋白质供应量不应强制适用于每个儿童。讨论了各年龄组及个体儿童的蛋白质供应情况。
