One of the easiest ways to help combat an iron deficiency is eating iron-rich food. We all know that iron is one of the most important minerals we need to function properly. As Katie Sanger, MS, MA, a registered dietitian at WellTheory, explains it, iron is needed to deliver oxygen, give us energy, boost our immune system, and produce hormones. Sanger adds that iron is important for cognitive function, as it makes sure that we maintain our focus, memory, and concentration. And when we don’t get enough iron, Samantha Dieras, DCN, RD, director of ambulatory nutrition services at Mount Sinai Hospital, says we can experience fatigue, weakness, shortness of breath, pale or yellow skin, heart palpitations, headaches, brittle nails, and hair loss.

Luckily for us, iron-rich food is pretty easy to find and incorporate into our diets. There are just a few things to take note of.

What types of iron are in food?

There are two types of iron you can find in food: heme iron and nonheme iron. Dieras says heme iron is more biologically available and easier for your body to absorb. This type of iron, she says, can be found in meat products such as red meat, organ meat, poultry, and eggs. You can also find heme iron in seafood. Nonheme iron can be found in nuts, seeds, beans, vegetables, and fortified foods such as cereals and breads. One type of iron isn’t necessarily better than the other. You just have to be mindful that your body may not absorb the nonheme iron as easily, meaning you might need to increase your iron-rich food intake to get the amount your body needs.

How much iron one needs is dependent on several factors, including your age, sex, and overall health. Sanger says that in general, adults ages 19 to 50 need anywhere from 8 to 18 mg of iron a day. Pregnant individuals need 27 mg, and adults 51 years and older need about 8 mg of iron. Some of the best foods to keep your iron levels high include:

Red Meat

Red meat is a great source of iron. According to the Dietary Guidelines for Americans created by the USDA and Department of Health and Human Services, 3 oz. of beef contains about 2.5 mg of iron.

Poultry

If you’re trying to limit your red-meat intake, you can always turn to poultry for your meat fix and iron intake. Sanger says chicken breast and roast turkey are great options. Three oz. of turkey contains 2 mg of iron, while chicken contains almost 1 mg per every 3 oz. cooked.

Organ Meats

You can also eat liver, tongue, oxtail, and other organ meats for iron. According to the Dietary Guidelines for Americans, organ meats contain about 1.8 to 1.9 mg of iron for every 3 oz. cooked.

Eggs

Need more reason to believe that breakfast is the most important meal of the day? Eating eggs regularly will help you get your needed iron. According to the National Institutes of Health, one chicken egg contains 0.9 mg of nonheme iron, with most of the iron found in the yolk. The Dietary Guidelines for Americans adds that one turkey egg offers 3.2 mg of iron and one duck egg has about 2.7 mg.

Dark Chocolate

Dark chocolate continues to prove that it’s the superior indulgence for those of us with a serious sweet tooth. On top of its other health benefits, such as its anti-inflammatory properties and ability to lower cholesterol, it’s an iron-rich food. Sanger says 1 oz. of dark chocolate can contain 3.4 mg of iron.

Legumes

If you’re looking for nonmeat options to reach your necessary iron level, turn to legumes. These plants, which include chickpeas and lentils, are rich in the nutrient. Half a cup of cooked chickpeas contains about 2.4 mg of iron and half a cup of lentils contains about 3.3 mg. Other legumes such as green peas can contain about 2.5 mg of iron for every cup cooked.

Spinach

Spinach is an easy vegetable to incorporate into your meals, and it is one of the most iron-rich foods out there. The Dietary Guidelines for Americans says one cup of cooked spinach will give you 6.4 mg of iron.

Black Beans

Black beans are one of the most iron-rich legumes you can eat. Sanger says one cup of cooked black beans contains 3.6 mg of iron. Other beans are also super-rich in the nutrient. One cup of cooked lima beans contains 4.9 mg of iron and half a cup of cooked soybeans 4.4 mg of iron.

Nuts

Whether you like to snack on nuts or add them to bigger meals, these foods are extremely beneficial to your diet. The Dietary Guidelines for Americans says an ounce of cashews, for example, contains 1.9 mg of iron.

Oysters and Other Seafood

Those happy-hour oysters aren’t just beneficial for our wallets. According to the Dietary Guidelines for Americans, having just three oysters gets you 6.9 mg of iron. You can also turn to other seafood if oysters aren’t something you crave. Clams, crabs, and sardines all contain 2.5 mg of iron for every 3 oz. serving. Shrimp has 1.8 mg of iron for every 3 oz.

Potatoes

Potatoes are rich in vitamins and nutrients, especially iron. Sanger says a medium-sized potato contains 1.9 mg of iron. Meanwhile, the Dietary Guidelines for Americans says one cup of cooked sweet potatoes also includes 1.9 mg of iron.

Brown Rice

Grains are one of the best food options if you’re looking to add more iron to your diet. Take brown rice, for instance, which has 0.8 mg of iron for every one cup cooked.

Oatmeal

Easy to make and hearty enough to keep you full all morning (or whenever you feel like eating it), oatmeal can help up your daily iron intake, Sanger says. According to the Dietary Guidelines for Americans, one cup of oats contains 9 mg of iron.

Cereal

Dieras recommends looking to fortified foods such as cereal for iron-rich options that are easy to incorporate into meals. The Dietary Guidelines for Americans lists that half a cup of ready-to-eat whole-wheat cereal contains 16.2 mg of iron, and one cup of hot wheat cereal contains 12.8 mg.

When should you use iron supplements?

Sanger says iron supplements are often prescribed to those who are diagnosed with iron deficiency, consume little to no animal products, or struggle with heavy menstrual cycles, as well of those who have undergone surgery or experienced an injury. “Iron supplements can be extremely helpful when addressing iron deficiency or iron-deficiency anemia,” she says. “But their use should always be guided by proper testing and professional advice.”

Dieras agrees and says it’s not recommended to take iron supplements without a doctor’s supervision. Too much iron in your system is just as bad as not having enough. “High doses of iron can be fatal, cause organ failure, coma, and convulsions,” she says. “Large amounts of iron can cause inflammation of the stomach lining and ulcers and decrease zinc absorption.”

As with anything related to your diet and overall health, be sure to ask your doctor if you’re concerned about your iron intake. But at the very least, you can start focusing on adding these foods to your diet. Most, if not all, of these foods are packed with other nutrients and vitamins, too, so adding these foods to your diet won’t hurt either way.
