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 .
A preliminary simulated iron fortification trial in South Indian preschool children.
1 . The effect of fortification of food with iron to provide 10 mg elemental Fe/child per d was studied in preschool children maintained on a cereal diet , over a 5-month period . 2 . The absorption of 5 mg Fe as ferrous sulphate mixed in one meal was 3.3 % of the test dose and when 3.3 mg was given with each of three meals over a 2 d period the corresponding value was 4.8 % . 3 . The mean absorption of a test dose of ferrous ascorbate  studied in twenty-four children midway through the trial was 42 % . 4 . The only beneficial effect of Fe fortification in this time-period in the experimental group was the prevention of the decrease in packed cell volume which occurred in the control groups
