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

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

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

Quinoa is also higher in protein than many other grains, as well as rich in folate, magnesium, copper, manganese, and many other nutrients.

In addition, quinoa has more antioxidant activity than many other grains. Antioxidants help protect your cells from damage from free radicals, which are formed during metabolism and in response to stress (33Trusted Source , 34Trusted Source ).

SUMMARY

Quinoa provides 16% of the DV for iron per serving. It also contains no gluten and is high in protein, folate, minerals, and antioxidants.

8. Turkey

Turkey meat is a healthy and delicious food. It’s also a good source of iron, especially dark turkey meat.

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
