A 6-ounce glass of red table wine contains 5 percent of the recommended daily allowance of iron. However, red wine may reduce the absorption of dietary iron. People whose iron levels are low should consider limiting intake of red wine with iron-rich meals to ensure adequate absorption of the mineral.
Other foods that may inhibit iron absorption include high-fiber foods, high-calcium foods, chocolate, coffee and tea. Some medications, including antacids, also may decrease absorption of iron. Foods high in iron include many types of meat, vegetables, fruits, breads and beans. Too much iron can cause excessive blood levels that lead to iron toxicity, a dangerous medical condition. The recommended iron limit is 45 milligrams per day for adults and 40 milligrams for children younger than 14.
