IRON STATUS AND INTAKE OF OLDER INFANTS FED FORMULA VS COW MILK WITH CEREAL

One hundred four infants were randomly assigned to receive whole cow milk plus iron-fortified cereal (WCM + C) in accord with the previous recommendations of the Committee of Nutrition/American Academy of Pediatrics (CON/APP); one of two iron-fortified, follow-up formulas; or an iron-fortified infant formula. Mean iron intakes and vitamin C exceeded the recommended dietary allowance in all groups. By 12 mo of age, mean ferritin and mean corpuscular volume were lower in the WCM + C group and significantly more infants had serum ferritin concentrations < 12 mug/L. We conclude that infants 6-12 mo of age fed whole cow milk and iron-containing table food are at risk of developing depleted iron stores but not anemia. The iron insufficiency in these infants is not due to inadequate intake of iron or vitamin C, but probably to relatively poor bioavailability of iron in infant cereal.
