Four infants were studied who had been exclusively breast-fed for periods varying from 8 to 18 months. All had grown sufficiently to have exhausted their prenatally acquired iron endowment with respect to meeting current needs for maintaining normal hemoglobin levels. All infants had normal hemoglobin values and normal serum iron values. Studies of iron absorption from breast milk and cow's milk were performed in ten normal adults. The absorption of iron from the human milk was significantly higher. These findings suggest that the iron present in human milk is sufficient to meet the iron requirements of the exclusively breast-fed infant until he approximately triples his birthweight.
对4名纯母乳喂养8至18个月的婴儿进行了研究。所有婴儿都已充分成长，就维持正常血红蛋白水平的当前需求而言，他们出生前获得的铁储备已耗尽。所有婴儿的血红蛋白值和血清铁值均正常。在10名正常成年人中进行了母乳和牛奶中铁吸收的研究。母乳中铁的吸收明显更高。这些发现表明，母乳中的铁足以满足纯母乳喂养婴儿直到其出生体重增加约两倍时对铁的需求。
