We compared iron intake and iron nutritional status of two groups of healthy term infants who received meat-containing baby foods fortified with ferrous sulphate (2 mg Fe/100 g). One group received an Fe-fortified formula (1.6 mg Fe/100 kcal) and the other a nonfortified formula. Fe intake of the group fed the nonfortified formula was significantly lower (p less than 0.0001). These infants received Fe mainly from fortification Fe with beikost (75-86%) and less than 10% met the recommended intake of 1 mg.kg-1.d-1; whereas 80-85% of the infants fed the Fe-fortified formula did. Hb, Hct, FEP, and ferritin were similar in both groups with the exception of lower ferritin values at age 365 d (p less than 0.05) in the group fed the nonfortified formula. No infant had hemoglobin less than 100 g/L. We conclude that regular consumption of commercially prepared Fe-fortified beikost with meat prevents most healthy term infants from Fe deficiency even if Fe intake is substantially below the recommended intake.
我们比较了两组健康足月儿的铁摄入量和铁营养状况,这两组婴儿食用的是添加硫酸亚铁(2毫克铁/100克)的含肉类辅食。一组婴儿食用强化铁配方奶(1.6毫克铁/100千卡),另一组食用未强化的配方奶。食用未强化配方奶组的铁摄入量显著较低(p小于0.0001)。这些婴儿的铁主要来自辅食中的强化铁(75%-86%),不到10%的婴儿达到了1毫克·千克⁻¹·天⁻¹的推荐摄入量;而食用强化铁配方奶的婴儿中有80%-85%达到了该摄入量。两组婴儿的血红蛋白、血细胞比容、游离原卟啉和铁蛋白水平相似,但食用未强化配方奶组在365日龄时铁蛋白值较低(p小于0.05)。没有婴儿的血红蛋白低于100克/升。我们得出结论,即使铁摄入量大幅低于推荐摄入量,经常食用市售的含肉强化铁辅食也能防止大多数健康足月儿出现缺铁情况。
