Effect of using commercial pre-packaged baby foods on the Fe intake of 7-8 months old infants.

Abstract

To examine the potential effect on Fe intake of 7-8 months old infants if pre-packaged baby foods (PBF) were used as the sole source of complementary foods. Based on the 7-d recommended feeding plan for 7-8 months old infants in Hong Kong (moderate Fe-fortified rice cereal with home-cooked meals), twenty-four modelling scenarios were created which comprised of two milk use modes (breastmilk v. infant formula), three modes of rice cereal use (no-rice cereal; non-Fe-fortified rice cereal and Fe-fortified rice cereal) and four baby foods usage modes (home-cooked meals; low-Fe PBF only; high-Fe PBF only and mixed PBF). The PBF were randomly selected in each of the models and substituted the original meals/snacks. The average daily Fe intakes of the modelled meal plans were compared with the Chinese estimated average requirement (EAR) and recommended nutrient intake (RNI) for Fe. Modelling study. Not applicable. In general, the infant-formula-based complementary feeding pattern (CFP) had higher average daily Fe intake when compared with breastmilk-based CFP. The Fe intakes of all scenarios under the breastmilk-based CFP were below the RNI and EAR, except for the fortified rice cereal meal plans with high-Fe or mixed PBF. For infant-formula-based CFP, the Fe intakes were close to or above the RNI regardless of types of PBF or rice cereal used. The inclusion of fortified rice cereal was important in maintaining adequate Fe intake for infants, especially for breast-fed infants. The replacement of home-cooked meals by low-Fe PBF could potentially put infants at risk of Fe deficiency.
