What foods get rid of excess iron and how to manage your diet

For those with conditions like hemochromatosis, iron absorption can be dramatically increased, causing excess iron to build up in the body. While diet alone cannot treat severe iron overload, incorporating certain foods and beverages that inhibit iron absorption can be an effective way to help manage your body's iron levels alongside medical treatment.

Quick Summary

Learn which dietary components, such as phytates, tannins, oxalates, and calcium, can naturally inhibit the body's uptake of iron. Strategic timing of meals and specific food pairings are key for effective management.

Key Points

Incorporate Phytate-Rich Foods: Add whole grains, legumes, and nuts to your meals to reduce iron absorption.
Drink Tea and Coffee Strategically: Consume beverages high in tannins, like black tea and coffee, with or just after meals to inhibit iron absorption.
Pair Calcium with Iron-Rich Meals: Include milk, yogurt, or cheese with your meals, as calcium is a known inhibitor of both heme and non-heme iron.
Time Your Vitamin C Intake: Avoid taking vitamin C with iron-rich meals, as it significantly enhances absorption. Instead, consume vitamin C-rich foods between meals.
Limit Red and Organ Meats: Reduce your intake of red and organ meats, as they are high in easily absorbed heme iron.
Use Non-Cast-Iron Cookware: Cook with stainless steel or other non-iron materials to prevent additional iron from leaching into your food.
Consult a Professional: Always work with a healthcare provider to manage iron overload, as diet is a complementary strategy, not a primary treatment.

Understanding How Diet Influences Iron Absorption

Iron is an essential mineral, but for individuals who absorb too much, managing intake is crucial. The goal isn't to eliminate iron entirely but to reduce the amount the body absorbs from food. This is achieved by increasing the consumption of certain inhibitors—natural compounds that bind to iron and hinder its absorption.

Dietary iron comes in two main forms: heme and non-heme. Heme iron is found in animal products like red meat and is more easily absorbed by the body. Non-heme iron, found in plant-based sources, is less bioavailable and more susceptible to dietary inhibitors. Knowing which foods contain these inhibitors is the first step toward building a more controlled diet.

Key Dietary Inhibitors of Iron Absorption

Foods High in Phytates

Phytates, or phytic acid, found in plant seeds, can interfere with iron absorption. Foods containing phytates include whole grains like oats and brown rice, legumes such as beans and lentils, and nuts and seeds. Soaking legumes can reduce phytic acid, which is beneficial for managing iron.

Tannin and Polyphenol-Rich Foods

Polyphenols, including tannins, are antioxidants in plants that strongly inhibit non-heme iron absorption. These are found in tea, coffee (which can inhibit absorption by up to 60%), cocoa, dark chocolate, certain fruits like berries and grapes, and spices such as oregano. Red wine also contains tannins.

High-Calcium Foods

Calcium is unique because it inhibits both heme and non-heme iron absorption. Incorporating calcium-rich foods with meals can help reduce iron uptake. Sources include dairy products, tofu (which also contains phytates), green leafy vegetables like spinach, sardines, canned salmon, and figs.

Oxalates and Phosvitin

Oxalates in plant-based foods impair non-heme iron absorption. Phosvitin in egg yolks binds to iron, preventing its absorption; one boiled egg can reduce absorption by up to 28%. Foods with oxalates include spinach, beets, and chocolate.

Inhibitors vs. Enhancers: A Comparison Table

Understanding what inhibits versus enhances iron absorption is helpful for dietary management. The table below summarizes key differences.


Feature	Inhibitors (Reduce Iron Absorption)	Enhancers (Increase Iron Absorption)
Key Compounds	Phytates, Tannins, Polyphenols, Calcium, Oxalates, Phosvitin	Vitamin C (Ascorbic Acid), Alcohol, Sugar, Lactic Acid
Associated Foods	Whole grains, legumes, nuts, seeds, tea, coffee, dark chocolate, dairy, eggs, spinach, kale	Citrus fruits, red bell peppers, strawberries, wine, sugary drinks, alcohol
Dietary Strategy	Consume with meals to reduce absorption, especially if managing iron overload	Consume separately from iron-rich meals, or if iron-deficient, pair with iron-rich foods
Timing	Best consumed with meals to maximize inhibitory effect	Avoid consuming with meals that contain iron-rich foods
Food Type	Primarily non-heme sources, but calcium can inhibit both types	Strongest effect on non-heme iron from plant sources

Practical Dietary Management for Excess Iron

Strategic eating habits, in addition to specific foods, can help control iron levels. Pair iron-rich foods with inhibitors, like having milk or tea with red meat. Consume iron absorption enhancers, like vitamin C, between meals instead of with them. Limit or avoid red and organ meats high in heme iron. Avoid raw shellfish due to increased risk in high-iron individuals. Use non-iron cookware to prevent iron leaching, especially with acidic foods. Limit alcohol, which can increase non-heme iron absorption and harm the liver in iron overload.

Conclusion: A Balanced Approach to Iron Management

Incorporating foods that get rid of excess iron by hindering absorption, such as those rich in phytates, tannins, and calcium, is a valuable part of managing conditions like hemochromatosis. Dietary changes are supportive and not a standalone treatment. Always consult a healthcare professional or registered dietitian for personalized advice to ensure nutritional balance.

Frequently Asked Questions

No, diet alone cannot cure hemochromatosis. While dietary management is a crucial supportive measure, it is not a replacement for primary medical treatments like phlebotomy or chelation therapy.

Calcium is a potent inhibitor of both heme and non-heme iron absorption. By consuming high-calcium foods like dairy or fortified tofu with an iron-rich meal, you can decrease the amount of iron your body absorbs.

No, but you should time your intake carefully. Since vitamin C enhances non-heme iron absorption, it is best to consume vitamin C-rich fruits and vegetables between meals, rather than with them, if you are managing excess iron.

Yes, egg yolks contain a protein called phosvitin, which binds to iron molecules and significantly reduces absorption. One boiled egg can lower absorption by nearly 30%.

To maximize the inhibitory effect of tannins, consume tea or coffee either with your meal or immediately after. Having it between meals will not have the same effect.

Most plant-based foods contain non-heme iron, which is less absorbable. However, some, like spinach, also contain inhibitors like oxalates and calcium that further limit absorption, making them a good choice.

It is best to avoid cooking in a cast-iron skillet, especially with acidic foods. Iron can leach from the pan into your food, unintentionally increasing your dietary iron intake.

You can eat red meat in moderation, but you should minimize your intake. When you do, pair it with foods rich in iron inhibitors, such as a cup of tea, to mitigate absorption.
