Iron is a mineral that serves several important functions, its main one being to carry oxygen throughout your body as a part of red blood cells (1Trusted Source).

It’s an essential nutrient, meaning you must get it from food. The Daily Value (DV) is 18 mg.

Interestingly, the amount of iron your body absorbs is partly based on how much you have stored.

A deficiency can occur if your intake is too low to replace the amount you lose every day (2Trusted Source).

Iron deficiency can cause anemia and lead to symptoms like fatigue. Menstruating women who don’t consume iron-rich foods are at a particularly high risk of deficiency.

Luckily, there are plenty of good food choices to help you meet your daily
iron needs.

Here are 12 healthy foods that are high in iron.

1. Shellfish

Shellfish is tasty and nutritious. All shellfish is high in iron, but clams, oysters, and mussels are particularly good sources.

For instance, a 3.5-ounce (100-gram) serving of clams may contain up to 3 mg of iron, which is 17% of the DV (3Trusted Source).

However, the iron content of clams is highly variable, and some types may contain much lower amounts (4).

The iron in shellfish is heme iron, which your body absorbs more easily than the non-heme iron found in plants.

A 3.5-ounce serving of clams also provides 26 grams of protein, 24% of the DV for vitamin C, and a whopping 4,125% of the DV for vitamin B12.

In fact, all shellfish is high in nutrients and has been shown to increase the level of heart-healthy HDL cholesterol in your blood (5Trusted Source).

Although there are legitimate concerns about mercury and toxins in certain types of fish and shellfish, the benefits of consuming seafood far outweigh the risks (6Trusted Source).

SUMMARY

A 3.5-ounce (100-gram) serving of clams provides 17% of the DV for iron. Shellfish is also rich in many other nutrients and may increase HDL (good) cholesterol levels in your blood.

2. Spinach

545874501

Spinach provides many health benefits but very few calories.

About 3.5 ounces (100 grams) of raw spinach contain 2.7 mg of iron, or 15% of the DV (7Trusted Source).

Although this is non-heme iron, which isn’t absorbed very well, spinach is also rich in vitamin C. This is important since vitamin C significantly boosts iron absorption (8Trusted Source).

Spinach is also rich in antioxidants called carotenoids, which may reduce your risk of cancer, decrease inflammation, and protect your eyes from disease (9Trusted Source, 10Trusted Source, 11Trusted Source, 12Trusted Source).

Consuming spinach and other leafy greens with fat helps your body absorb the carotenoids, so make sure to eat a healthy fat like olive oil with your spinach (13Trusted Source).

SUMMARY

Spinach provides 15% of the DV for iron per serving, along with several vitamins and minerals. It also contains important antioxidants.

3. Liver and other organ meats

Organ meats are extremely nutritious. Popular types include liver, kidneys, brain, and heart — all of which are high in iron.

For example, a 3.5-ounce (100-gram) serving of beef liver contains 6.5 mg of iron, or 36% of the DV (14Trusted Source).

Organ meats are also high in protein and rich in B vitamins, copper, and selenium.

Liver is especially high in vitamin A, providing an impressive 1,049% of the DV per 3.5-ounce serving.

What’s more, organ meats are among the best sources of choline, an important nutrient for brain and liver health that many people don’t get enough of (15Trusted Source).

SUMMARY
Organ meats are good sources of iron, and liver contains 36% of the DV per serving. Organ meats are also rich in many other nutrients, such as selenium, vitamin A, and choline.

4. Legumes

Legumes are loaded with nutrients.

Some of the most common types of legumes are beans, lentils, chickpeas, peas, and soybeans.

They’re a great source of iron, especially for vegetarians. One cup (198 grams) of cooked lentils contains 6.6 mg, which is 37% of the DV (16Trusted Source).

Beans like black beans, navy beans, and kidney beans can all help easily bump up your iron intake.

In fact, a half-cup (86-gram) serving of cooked black beans provides around 1.8 grams of iron, or 10% of the DV (80Trusted Source).

Legumes are also a good source of folate, magnesium, and potassium.

What’s more, studies have shown that beans and other legumes can reduce inflammation in people with diabetes. Legumes can also decrease heart disease risk for people with metabolic syndrome (17Trusted Source, 18Trusted Source, 19Trusted Source, 20Trusted Source).

Additionally, legumes may help you lose weight. They’re very high in soluble fiber, which can increase feelings of fullness and reduce calorie intake (21Trusted Source).

In one study, a high fiber diet containing beans was shown to be as effective as a low carb diet for weight loss (22Trusted Source).

To maximize iron absorption, consume legumes with foods high in vitamin C, such as tomatoes, greens, or citrus fruits.

SUMMARY

Meat is also rich in protein, zinc, selenium, and several B vitamins (24Trusted Source).

Researchers have suggested that iron deficiency may be less likely in people who eat meat, poultry, and fish on a regular basis (25Trusted Source).

In fact, red meat is probably the single most easily accessible source of heme iron, potentially making it an important food for people who are prone to anemia.

In one study looking at changes in iron stores after aerobic exercise, women who consumed meat retained iron better than those who took iron supplements (26Trusted Source).

A 3.5-ounce (100-gram) portion of dark turkey meat has 1.4 mg of iron, which is 8% of the DV (35Trusted Source).

In comparison, the same amount of white turkey meat contains only 0.7 mg (36Trusted Source).

Dark turkey meat also packs an impressive 28 grams of protein per serving and several B vitamins and minerals, including 32% of the DV for zinc and 57% of the DV for selenium.

Consuming high protein foods like turkey may aid weight loss, as protein makes you feel full and increases your metabolic rate after a meal (37Trusted Source, 38Trusted Source, 39Trusted Source).

High protein intake can also help prevent the muscle loss that occurs during weight loss and the aging process (40Trusted Source, 41Trusted Source).

SUMMARY

Turkey provides 13% of the DV for iron and is a good source of several vitamins and minerals. Its high protein content promotes fullness, increases metabolism, and prevents muscle loss

9. Broccoli

1124267403

Broccoli is incredibly nutritious. A 1-cup (156-gram) serving of cooked broccoli contains 1 mg of iron, which is 6% of the DV (42Trusted Source).

What’s more, a serving of broccoli also packs 112% of the DV for vitamin C, which helps your body absorb the iron better (8Trusted Source, 43Trusted Source).

The same serving size is also high in folate and provides 5 grams of fiber, as well as some vitamin K. Broccoli is a member of the cruciferous vegetable family, which also includes cauliflower, Brussels sprouts, kale, and cabbage.

Cruciferous vegetables contain indole, sulforaphane, and glucosinolates, which are plant compounds believed to protect against cancer (44Trusted Source, 45Trusted Source, 46, 47Trusted Source).

SUMMARY

One serving of broccoli provides 6% of the DV for iron and is very high in vitamins C, K, and folate. It may also help reduce cancer risk.

The bottom line

Iron is an important mineral that must be consumed regularly as your body cannot produce it on its own.

Yet, it should be noted that some people need to limit their intake of red meat and other foods high in heme iron.

However, most people are easily able to regulate the amount they absorb from food.

Remember that if you don’t eat meat or fish, you can boost absorption by including a source of vitamin C when eating plant sources of iron.
