Sensitivity analyses and meta-regression for hemoglobin suggested a higher response with lower trial quality ( suboptimal allocation concealment and blinding ) , use of condiments , and sodium iron edetate and a lower response when adults were included .
Consumption of iron-fortified foods results in an improvement in hemoglobin , serum ferritin , and iron nutriture and a reduced risk of remaining anemic and iron deficient
BACKGROUND The utility of iron fortification of food to improve iron deficiency , anemia , and biological outcomes is not proven unequivocally .
Effect of supplementation with an iron-fortified milk on incidence of diarrhea and respiratory infection in urban-resident infants.
To address the hypothesis that increased infectious morbidity is associated with iron supplementation , 783 r and omly selected infants were provided with a powdered full fat cow 's milk ( non-fortified group ) and 872 with a  powdered acidified full fat cow 's milk fortified with 15 mg of iron as ferrous sulfate ( fortified group ) . All infants were followed from birth to 15 months of age with a monthly home visit by a nurse who recorded morbidity occurring during the previous 30 days . At 9 months of age , 15 % of infants in each cohort were receiving breast milk only ; data for these infants were segregated to make the third group . Episodes ( mean + /- SD ) of diarrhea/infant/year were 1.06 + /- 1.29 , 1.14 + /- 1.37 , and 0.82 + /- 1.04 for the fortified , non-fortified and breast-fed groups , respectively ; the fortified and non-fortified bottle-fed groups had a very similar incidence of respiratory illness ; 2.66 + /- 2.07 and 2.74 + /- 2.24 episodes/infant/year , respectively . The incidence of respiratory illness for both bottle-fed groups was significantly higher than that for the breast-fed group ( 2.22 + /- 1.84 respiratory episodes/infant/year ) . We conclude that for the infants the tested form of iron fortified milk , which is sufficient to lower iron deficiency anemia , does not result in an increased incidence of diarrhea or respiratory illness
