Can I get Iron toxicity or too much iron in my system if I eat fortified cereal? I am a male. The cereal has 25% DV Iron per serving, but it also has 7g fiber and I eat it with milk (reportedly slows down iron absorption). If I eat 3-4 servings of cereal a day, then can Iron accumulate in my body? Should I worry? Please explain in detail. Thanks.

Hi there! Welcome to the forum. 25%DV means that one serving on the cereal provides 25% of the daily requirement of an adult male. 3-4 servings would provide nearly 90-100% of the calcium requirement. However, serving with milk would decrease its absorption which would in turn compensate for the iron one gets from other sources/ food items. Toxic doses are far higher than the average daily intake and hence this is unlikely to result in toxicity. Hope this information is helpful. Please feel free to post any further queries that you may have and do keep us posted. Take care!

Hi, Welcome to the forum. How are you? I agree with Dr Kaul that eating 3-4 servings of fortified cereals, as in your case, unlikely results to iron toxicity. Iron recommendations and intakes for males age 19 to 51+ require 10 mg per day. Toxic effects begin to occur at doses above 10�20 mg/kg of elemental iron. And ingestion of more than 50 mg/kg of elemental iron is associated with severe toxicity. Normally, the body absorbs less iron if its stores are full. However, iron overload can be due to defective gene, repeated blood transfusions, massive doses of dietary iron, and rare metabolic disorders. With regards to other food sources, iron occurs in two forms: heme and nonheme. Heme iron is found only in foods derived from the flesh of animals while nonheme iron is found in both plant and animal foods. Meat, poultry and fish are good sources of heme iron while legumes, dark green leafy vegetables, green beans, tomato juice, parsley, artichoke, dried fruits and corn flour contain respectable amounts of nonheme iron. Hope this helps. Take care and best regards.
