Today we are going to be discussing about the complete list of iron rich foods you should know about. But first, let us try to understand how our body uses iron in food before proceeding to listing the iron rich foods and their iron content.
Iron is a mineral that serves several important functions, its main being to carry oxygen throughout your body and making red blood cells.
It’s an essential nutrient, meaning you must get it from food. The recommended daily intake (RDI) is 18 mg.
Interestingly, the amount 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.
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.
How Your Body Uses Iron in Food (Iron Rich Foods)
When you eat food with iron, iron is absorbed into your body mainly through the upper part of your small intestine.
There are two forms of dietary iron: heme and nonheme. Heme iron is derived from hemoglobin. It is found in animal foods that originally contained hemoglobin, such as red meats, fish, and poultry (meat, poultry, and seafood contain both heme and non-heme iron).
Your body absorbs the most iron from heme sources. Most nonheme iron is from plant sources.
Complete List of Iron Rich Foods you Should Know About
Now let us look at the list of iron rich foods that we have below:
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 28 mg of iron, which is 155% of the RDI.
However, the iron content of clams is highly variable, and some types may contain much lower amounts.
The iron in shellfish is heme iron, which your body absorbs more easily than the non-heme iron found in plants.
A serving of clams also provides 26 grams of protein, 37% of the RDI for vitamin C and a whopping 1,648% of the RDI 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.
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.
Summary A 3.5-ounce (100-gram) serving of clams provides 155% of the RDI for iron. Shellfish is also rich in many other nutrients and may increase “good” HDL cholesterol levels in your blood.
Spinach provides many health benefits for very few calories.
3.5 ounces (100 grams) of cooked spinach contain 3.6 mg of iron, or 20% of the RDI.
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.
Spinach is also rich in antioxidants called carotenoids that may reduce your risk of cancer, decrease inflammation and protect your eyes from disease.
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.
Summary Spinach provides 20% of the RDI 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 RDI.
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 634% of the RDI per 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.
Summary Organ meats are good sources of iron, and liver contains 36% of the RDI per serving. Organ meats are also rich in many other nutrients, such as selenium, vitamin A and choline.
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 RDI.
Legumes are also rich in 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.
Additionally, legumes may help you lose weight. They’re very high in soluble fiber, which can increase feelings of fullness and reduce calorie intake.
In one study, a high-fiber diet containing beans was shown to be as effective as a low-carb diet for weight loss.
In order to maximize iron absorption, consume legumes with foods high in vitamin C, such as tomatoes, greens or citrus fruits.
Summary One cup (198 grams) of cooked lentils provides 37% of the RDI for iron. Legumes are also high in folate, magnesium, potassium and fiber and may even aid weight loss.
5. Red Meat
Red meat is satisfying and nutritious and also one of the iron rich foods. A 3.5-ounce (100-gram) serving of ground beef contains 2.7 mg of iron, which is 15% of the RDI.
Meat is also rich in protein, zinc, selenium and several B vitamins.
Researchers have suggested that iron deficiency may be less likely in people who eat meat, poultry and fish on a regular basis.
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.
Summary One serving of ground beef contains 15% of the RDI for iron and is one of the most easily accessible sources of heme iron. It’s also rich in B vitamins, zinc, selenium and high-quality protein.
6. Pumpkin Seeds

A study found that cocoa powder and dark chocolate had more antioxidant activity than powders and juices made from acai berries and blueberries.
Studies have also shown that chocolate has beneficial effects on cholesterol and may reduce your risk of heart attacks and strokes.
However, not all chocolate is created equal. It’s believed that compounds called flavanols are responsible for chocolate’s benefits, and the flavanol content of dark chocolate is much higher than that of milk chocolate.
Therefore, it’s best to consume chocolate with a minimum of 70% cocoa to get the maximum benefits.
Summary A small serving of dark chocolate contains 19% of the RDI for iron along with several minerals and prebiotic fiber that promotes gut health.
The Bottom Line
Iron is an important mineral that must be consumed regularly as your body cannot produce it on its own thereby making the consumption of Iron Rich Foods compulsory for our well-being.
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.
