母乳喂养的婴儿的能量摄入是不确定的。双标记水方法被用来测量，同时和非侵入性，能量消耗，能量摄入量，牛奶体积摄入量，能量沉积，和母乳中的能量含量在12个“自由生活”母乳喂养的婴儿在5和11周龄。在12名配方奶粉喂养婴儿的平行研究中评估了这种新方法的有效性。纯母乳喂养的婴儿在5周和11周时消耗1.28和1.68 MJ/天，摄入量为1.81和2.22 MJ/天;这些摄入量与正常生长有关，但远低于先前推荐的摄入量。在第5周和第11周，计算的母乳能量含量为0.24和0.25 MJ/100 ml，这大大低于通常报道的通过乳房挤出非生理性获得的乳汁中的能量含量。这些数据对广泛使用的婴儿喂养标准提出了质疑。
Energy intake in breast fed infants is uncertain. The doubly labelled water method was used to measure, simultaneously and non-invasively, energy expenditure, energy intake, milk volume intake, energy deposition, and the energy content of breast milk in 12 "free living" breast fed babies at 5 and 11 weeks of age. The validity of this new approach was assessed in a parallel study in 12 formula fed infants. The babies who were exclusively breast fed expended 1.28 and 1.68 MJ/day at five and 11 weeks and had intakes of 1.81 and 2.22 MJ/day; these intakes were associated with normal growth but were well below those recommended previously. At five and 11 weeks the calculated energy content of breast milk was 0.24 and 0.25 MJ/100 ml, which is substantially lower than that commonly reported in milk obtained unphysiologically by expression of the breast. These data cast doubt on the widely used published standards for infant feeding.
