Evaluating The Influence Of Extrinsic Iron From Soil Contaminated Teff On Hemoglobin Regeneration Of Anemic Rats Indicator Of Bioavailability Of Extrinsic Iron.

Iron deficiency is prevalent in Ethiopia despite high dietary intake. The contribution of iron fromrnextrinsic sources from soil contamination during threshing is likely to be high. However, thernactual bioavailability of contaminant iron remains unknown. The objective of this study was torndetermine the level of iron in field and laboratories threshed flours of teff from the same varietyrnand investigate the iron bioavailability of the intrinsic and extrinsic iron associated with teffrnusing rat hemoglobin repletion assay. Two samples of red teff grown in a similar condition wererncollected; one harvested and threshed in the laboratory and the other threshed traditionally.rnFlours from the two samples were analyzed for their dry matter, proximate composition, totalrniron contents and in vivo bioavailability was evaluated using rat hemoglobin repletion bioassayrnand was compared to the standard ferrous sulfate. Protein, fat and total carbohydrate contents ofrnlaboratory threshed and field threshed teff flours were shown to have no statistically significantrndifference (p>0.05). Field threshed teff (3.3+0.31 g/100g) has significantly higher ash contentrnthan the lab threshed (1.8+0.16 g/100g) (p
