Iron deficiency up-regulates iron absorption from ferrous sulphate but not ferric pyrophosphate and consequently food fortification with ferrous sulphate has relatively greater efficacy in iron-deficient individuals.
Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain. Our objectives were therefore (1) to compare the up-regulation of Fe absorption at low Fe status from ferrous sulphate (FS) and ferric pyrophosphate (FPP) and (2) to compare the efficacy of FS with FPP in a fortification trial to incre...
متن کاملOlfactory ferric and ferrous iron absorption in iron-deficient rats.
The absorption of metals from the nasal cavity to the blood and the brain initiates an important route of occupational exposures leading to health risks. Divalent metal transporter-1 (DMT1) plays a significant role in the absorption of intranasally instilled manganese, but whether iron uptake would be mediated by the same pathway is unknown. In iron-deficient rats, blood (59)Fe levels after int...
متن کاملIron absorption from rice meals cooked with fortified salt containing ferrous sulphate and ascorbic acid.
I . Iron absorption from rice-containing meals was measured by red cell utilization of radioactive Fe in sixty-six voluntcer multiparous Jndian women. 2. In all the studies salt added during the cooking process wiis used as the carrier for supplemental inorganic Fe and ascorbic acid. 3. Intrinsic Fe in the rice and supplementary inorganic Fe were absorbed to the same extent, with a wide range o...
متن کاملIron absorption from ferrous bisglycinate and ferric trisglycinate in whole maize is regulated by iron status.
BACKGROUND There is a need to determine whether iron absorption from iron amino acid chelates is protected from inhibition by dietary phytate and regulated normally by iron status. OBJECTIVE The objective of this study was to compare iron absorption from ferrous sulfate, ferrous bisglycinate, and ferric trisglycinate in whole-maize meal; to determine whether iron from ferrous bisglycinate and...
متن کاملEvaluation of Ferric and Ferrous Iron Therapies in Women with Iron Deficiency Anaemia
Introduction. Different ferric and ferrous iron preparations can be used as oral iron supplements. Our aim was to compare the effects of oral ferric and ferrous iron therapies in women with iron deficiency anaemia. Methods. The present study included 104 women diagnosed with iron deficiency anaemia after evaluation. In the evaluations performed to detect the aetiology underlying the iron defici...
