Ferric sodium ethylenediaminetetraacetate (NaFeEDTA) enhances iron absorption in the presence of phytate. However, the amount of NaFeEDTA that would have to be added to a complementary food to provide the necessary intake of iron for an infant or young child

The Journal of nutrition, 142(11), 1950-1955 (2012-09-20)
Limited data exist on iron absorption from NaFeEDTA and FeSO(4) in legume-based flours. The current study compared iron absorption from NaFeEDTA and FeSO(4) as fortificants within and between red and white varieties of cowpea with different concentrations of polyphenols (PP)

The Journal of nutrition, 142(10), 1836-1842 (2012-08-24)
Cowpeas, like other legumes, contain high amounts of native iron but are rich in phytic acid (PA) and polyphenols (PP) that inhibit iron absorption. NaFeEDTA may overcome the combined inhibitory effect of PA and PP. Our objective was to test

Biochemistry, 50(28), 6273-6279 (2011-06-24)
Oxidation of the C5'-position of DNA results in direct strand scission. The 3'-fragments produced contain DNA lesions at their 5'-termini. The major DNA lesion contains an aldehyde at its C5'-position, but its nucleobase is unmodified. Excision of the lesion formed

Food and nutrition bulletin, 33(2), 128-136 (2012-08-23)
Oral iron supplementation with ferrous sulfate (FeSO₄) at dosage levels suggested by the international guidelines poses a safety hazard to young children with malaria. Exposure to loosely bound iron in the circulation has been advanced as a potential factor. To
