The energy and nutrient intake of 6 and 12-month-old weaned Swedish infants was studied by means of 24-h recalls. Milk-cereal follow-up formulas played a dominating role in the diet, contributing 57 per cent of the total energy intake at 6 months and 26 per cent at 12 months. The ratio between the macronutrients was characterized by a high-protein and low-fat intake; 16-17 per cent of energy derived from protein and 29-33 per cent from fat at 6 and 12 months respectively. The protein intake was also high in absolute figures: 3.3 g per kg body-weight at 6 months and 4.2 g per kg at 12 months. The mean daily energy intake for these normally growing infants was 75 per cent of the recommended daily allowance (RDA) at 6 months, and the need for a revision of the energy allowances in infancy is discussed. The estimated daily intake of iron was equal to the RDA at 6 months and 80 per cent of the allowance at 12 months. The daily intake of vitamin D exceeded the RDA to such a degree, that the present level of vitamin D supplementation through oral drops is questioned.
通过24小时回顾法对6个月和12个月大的瑞典断奶婴儿的能量和营养摄入情况进行了研究。牛奶谷物后续配方奶粉在饮食中起主导作用，在6个月时占总能量摄入的57%，在12个月时占26%。宏量营养素之间的比例特点是高蛋白和低脂肪摄入；在6个月和12个月时，分别有16 - 17%的能量来自蛋白质，29 - 33%来自脂肪。蛋白质摄入量的绝对值也很高：6个月时为每公斤体重3.3克，12个月时为每公斤体重4.2克。这些正常生长婴儿的平均每日能量摄入量在6个月时为推荐每日摄入量（RDA）的75%，并讨论了婴儿期能量摄入量修订的必要性。估计的每日铁摄入量在6个月时等于RDA，在12个月时为摄入量的80%。每日维生素D摄入量超过RDA的程度如此之大，以至于目前通过口服滴剂补充维生素D的水平受到质疑。
