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 .
The haematinic effect of iron in flour.
1 . Two large-scale community based studies of the  haematinic effect of iron added to flour used to bake bread are reported . These were design ed to simulate conditions in the community as closely as possible . 2 . Neither trial gave conclusive evidence of benefit in terms of an effect on circulating haemoglobin level , but in one trial the results suggested a small haematinic effect . 3 . The availability of an iron salt from bread eaten in a normal varied diet is clearly much lower than has been suggested from highly controlled radioactive isotope studies
