Abstract
OBJECTIVES: 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. DESIGN: 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. SETTING: Modelling study. PARTICIPANTS: Not applicable. RESULTS: 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. CONCLUSIONS: 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.
