Iron is an essential nutrient that your body requires to function correctly. Since your body cannot produce iron on its own, you must obtain it through your diet. Iron plays a vital role in creating hemoglobin, a protein in red blood cells that carries oxygen throughout your body. Ensuring you consume enough iron is crucial for preventing iron deficiency and maintaining overall health. So, What Food Is High In Iron? Let’s explore the best dietary sources to help you meet your daily iron needs.
Understanding the Types of Iron in Food
Dietary iron comes in two main forms: haem iron and non-haem iron. The type of iron in food impacts how easily your body can absorb it.
-
Haem Iron: This type of iron is found in animal-based foods. It is derived from hemoglobin and myoglobin, proteins found in animal tissues. Haem iron is significantly more easily absorbed by the body compared to non-haem iron.
-
Non-Haem Iron: This type of iron is found in plant-based foods, eggs, and fortified foods. It is not part of hemoglobin and is less readily absorbed by the body. If you primarily consume non-haem iron sources, you may need to consume a higher quantity to meet your iron requirements.
Top Food Sources High in Haem Iron
If you are looking to boost your iron intake with easily absorbable sources, haem iron-rich foods are excellent choices. These foods are derived from animal sources and offer a significant iron boost.
- Meat: Red meat, particularly beef and lamb, is one of the richest sources of haem iron. Pork also provides a good amount of haem iron. Including lean meat in your diet a few times a week can significantly contribute to your iron levels.
- Poultry: Chicken and turkey are also good sources of haem iron, although they contain less than red meat. Darker poultry meat tends to be higher in iron than white meat. Eggs, especially the yolks, contain haem iron as well.
- Seafood: Fish and shellfish are valuable sources of haem iron. Excellent choices include salmon, tuna, sardines, and shellfish like oysters, clams, and mussels. Incorporating seafood into your meals is a delicious way to increase your iron intake.
- Organ Meats: Organ meats such as liver, kidney, and pate are exceptionally high in haem iron. While they may not be a dietary staple for everyone, they are incredibly nutrient-dense and can be included occasionally to significantly boost iron levels.
Plant-Based Foods High in Non-Haem Iron
For vegetarians, vegans, or anyone looking to incorporate more plant-based foods into their diet, there are many excellent sources of non-haem iron. While non-haem iron is less easily absorbed, you can enhance absorption by pairing these foods with vitamin C-rich foods (discussed later).
- Iron-Fortified Foods: Many breakfast cereals, breads, and plant-based milk alternatives are fortified with iron. Check the nutrition labels to identify fortified options. These can be a convenient way to increase iron intake, especially for those on plant-based diets.
- Nuts and Seeds: Nuts and seeds like pumpkin seeds, sesame seeds, cashews, almonds, and pine nuts provide non-haem iron. They also offer healthy fats and fiber. Snacking on a handful of nuts or seeds or adding them to meals can contribute to your daily iron intake.
- Dried Fruit: Dried fruits such as apricots, raisins, and prunes contain non-haem iron. However, they are also high in sugar, so consume them in moderation. They can be a convenient snack or addition to trail mixes and oatmeal.
- Whole Grains: Whole wheat pasta, bread, and brown rice offer non-haem iron, along with fiber and other essential nutrients. Choosing whole grain versions over refined grains can improve your overall nutrient intake, including iron.
- Legumes: Legumes are an excellent source of non-haem iron and protein. Lentils, chickpeas, beans (kidney beans, black beans, soybeans), and tofu are all iron-rich legumes that can be incorporated into various dishes like soups, stews, salads, and vegetarian entrees.
- Dark Leafy Green Vegetables: Dark leafy greens such as spinach, kale, collard greens, and Swiss chard contain non-haem iron. While the iron content in some leafy greens might seem high, the absorption can be lower due to compounds like oxalates. However, they are still valuable sources, especially when combined with vitamin C.
- Tofu: Tofu is a versatile soy-based protein that is also a good source of non-haem iron. It can be used in stir-fries, scrambles, and various vegetarian and vegan dishes.
How Much Iron Do You Need Daily?
The recommended daily intake (RDI) of iron varies based on age, sex, and life stage. Here are general guidelines:
- Children:
- 7-12 months: 11mg/day
- 1-3 years: 9mg/day
- 4-8 years: 10mg/day
- 9-13 years: 8mg/day
- Teenagers (14-18 years):
- Males: 11mg/day
- Females: 15mg/day
- Adults (19-50 years):
- Males: 8mg/day
- Females: 18mg/day
- Adults (50+ years): 8mg/day for both males and females
- Pregnant Women: 27mg/day
- Breastfeeding Women:
- 14-18 years: 10mg/day
- 19+ years: 9mg/day
Women of childbearing age require more iron due to iron loss during menstruation. Pregnant women have significantly increased iron needs to support both their own body and the developing fetus.
Tips to Maximize Iron Absorption
You can enhance your body’s absorption of iron, especially non-haem iron, by making smart dietary choices:
-
Consume Vitamin C-Rich Foods: Vitamin C significantly boosts the absorption of non-haem iron. Combine iron-rich plant-based foods with sources of vitamin C such as:
- Citrus fruits (oranges, lemons, grapefruits)
- Berries (strawberries, blueberries, raspberries)
- Kiwi fruit
- Melons
- Tomatoes
- Bell peppers
- Dark leafy green vegetables
Try squeezing lemon juice on spinach salad, adding bell peppers to lentil soup, or enjoying a side of berries with iron-fortified cereal.
-
Be Mindful of Iron Absorption Inhibitors: Certain foods and drinks can hinder iron absorption, particularly when consumed at the same time as iron-rich meals. These include:
- Coffee and Tea: Tannins in coffee and tea can reduce iron absorption. It’s best to consume these beverages between meals rather than with them.
- Red Wine: Similar to coffee and tea, red wine contains compounds that can inhibit iron absorption.
- Calcium-Rich Foods: While calcium is essential, high amounts consumed at the same time as iron-rich foods can interfere with iron absorption. This includes dairy products like milk, cheese, and yogurt, as well as calcium supplements. It’s advisable to consume dairy and calcium supplements at different times from iron-rich meals.
- Soybean-Based Foods: Some compounds in soybeans can also slightly reduce iron absorption.
It’s not necessary to completely avoid these items, but being mindful of their intake around your iron-rich meals can help optimize iron absorption.

What Happens If You Don’t Get Enough Iron?
Insufficient iron intake can lead to iron deficiency. Prolonged iron deficiency can result in iron deficiency anemia, a condition where your body doesn’t have enough red blood cells to carry adequate oxygen. Symptoms of iron deficiency can include:
- Fatigue and weakness
- Headaches
- Difficulty concentrating
- Pale skin
- Dizziness
- Shortness of breath
- Cold hands and feet
If you suspect you might be iron deficient, it’s important to consult your doctor. They can perform blood tests to check your iron levels and recommend appropriate treatment, which may include dietary changes or iron supplements.
Can You Consume Too Much Iron?
While iron is essential, consuming excessive amounts can be harmful. Iron overload can occur, particularly from taking iron supplements unnecessarily. It’s generally recommended to get iron primarily from food sources unless a doctor advises supplementation.
A genetic condition called haemochromatosis can cause the body to absorb and store too much iron. If you have a family history of haemochromatosis or concerns about iron overload, discuss this with your doctor.
Conclusion
Ensuring you consume enough iron-rich foods is vital for maintaining good health and preventing iron deficiency. By understanding the different types of iron, knowing which foods are high in iron, and employing strategies to enhance absorption, you can effectively meet your daily iron needs through diet. If you have concerns about your iron intake or suspect you might be deficient, it’s always best to consult with a healthcare professional for personalized advice and guidance.
