Iron overload disease, also known as hemochromatosis, is a disorder in which your body absorbs too much iron from your diet. Because the human body has no mechanism to excrete excess iron, the mineral accumulates in your liver and other body organs, potentially causing irreversible damage. Although rigid dietary restrictions typically are not recommended for patients with iron overload disease, discuss your consumption of iron-rich foods and your overall nutrition plan with your doctor.

Iron-Fortified Cereals

A single serving of certain iron-fortified cereals contains more than twice the recommended daily allowance of iron for men and post-menopausal women, according to the USDA National Nutrient Database. Although calcium in the milk poured on cereal reduces intestinal iron absorption, your doctor may recommend that you eat non-iron-fortified cereals.


Poultry giblets, which include the liver, kidneys and gizzard, contain a high concentration of iron. One cup of turkey or chicken giblets contains approximately 10 to 11 mg of iron, according to the USDA National Nutrient Database. However, if you chop cooked giblets and add them to gravy, dressing or soup, the amount of iron per serving drops substantially.
Liver

Your doctor may recommend that you limit your intake of beef liver if you have iron overload disease. A 3-oz. serving of beef liver contains more than 5 mg of iron, reports the USDA National Nutrient Database. Drinking alcohol along with a meal that contains liver or another high-iron food increases the absorption of the mineral from your small bowel, reports the Iron Disorders Institute. Alcohol consumption may also increase the level of liver damage associated with iron overload disease and should be avoided, especially if you have cirrhosis, advises the National Heart Lung and Blood Institute.
Beef

Beef and other red meats contain heme-iron, which is more readily absorbed from your intestine than plant-derived iron. Many doctors recommend limiting or avoiding red meat if you have iron overload disease. A 3-oz. serving of beef, such as blade roast, bottom round or ribs, contains approximately 2 to 3 mg of iron, according to the USDA National Nutrient Database. A 3-oz. serving of ground beef contains roughly 2 mg of iron.
Venison

Venison contains a high concentration of heme-iron, with more than 4 mg per 3-oz. serving, according to the USDA. Your doctor may recommend you limit your intake or avoid eating venison if you have an iron overload disorder. Small amounts of venison in stews or soups may be permitted.
