  • Abstract The purpose of the study was to determine the effect of dietary iron on distribution of zinc, manganese, copper, calcium and magnesium in the body of Wistar rats. Commercial Sangak, an Iranian traditional flat bread was used in this study. It was prepared by additionof yeast and sourdough. Different doses of iron (35, 70, 140, and 210 mg/kg per diet) were added to bread vehicle for 30 days with or without baking soda (250 mg/kg per diet). The concentrations of the above elements were determined by graphite furnace and flame atomic absorption spectroscopy. Serum zinc and manganese concentrations were significantly lower (P < 0.05) in rats that received higher concentrations of iron compared to the controls. Serum iron, and copper concentrations increased significantly (P < 0.05) with an increase in dietary iron compared to the controls. Increments of dietary concentrations of iron raised the concentration of iron, zinc and manganese in the feces, and lowered the concentration of copper and calcium in the feces (P < 0.05). Diets that contained baking soda showed a statistically significant increase in phytic acid (P < 0.05). Lower serum iron was seen in rats that received baking soda with diet of the control group. Conversely, feces iron and zinc were increased in this group. It is concluded that iron absorption might interfere with zinc and manganese because of similar physicochemical properties. Knowledge about these interactions is essential when supplementation of some elements is recommended in populations with a high risk of some deficiencies such as iron and zinc.
