Possible Interaction: Selenium and Iron, Dietary

“Interestingly, high-fat diet, selenium and iron have incompatible effects on As bioaccessibility, metabolism and toxicity in different experimental conditions.”

“A significant negative correlation was reported between Se and Fe in BDL group (r = -0.935, p < 0.05).”

“… Fe … Se and Zn: a difference of 1 g kg-1 in soil Fe changed soil Se by 2.820 μg kg-1 and soil Zn …-1 in soil Ca changed soil Se by 3.249 μg kg-1 and soil Zn by 0.356 mg kg-1, respectively.”

“In turn, the scalp hair content of Se significantly exceeded the control values (33 %; p = 0.004), whereas the level of iron ( Fe ) and aluminum (Al) tended to increase.”

“Among micronutrients calcium, vitamin D, folates, flavonoids, antioxidant vitamins (A, C and E) and selenium can be protective meanwhile iron may enhance risk.”

“Significant correlations between Se and K, Fe , Ca, Mg, and Zn were noticed.”

“Thus, the source of Se compounds may influence the balance between Se and other trace elements including Zn, Mn, Fe , and Cu, which is important for proper antioxidant defense in blood and egg yolk of laying hens.”

“Yolk iron Fe ) and copper (Cu) concentrations in the NS group were also increased with Se supplementation.”

“Treatment with Pb increased concentrations of Ni while reducing those of B, V, Cr, Fe, Co, Cu, Zn, and Mo. Moreover, Se also reduced the concentration of Pb, Zn, Co, Fe , V, and Cr, which in contrast were induced by Pb.”

“This hypothesis is confirmed with regard to elements the values of which decrease significantly with the distance from the sewage emission point, e.g. Cr, Fe and Zn, and a little less for Ag, Ba, Ce, Rb, Sb, Sc, Se , Sm and Th.”

“Coexistence of high concentrations of Fe , As, Ni and Cu interferes with selenium determination.”
