The Best And Healthiest Iron-rich Foods

Iron is an essential nutrient (which means we must get it from food) and a very important mineral that our bodies need to function properly. It plays a vital role in many crucial body processes. Iron is a part of hemoglobin – a protein in red blood cells, which enables the cells to carry oxygen from the lungs to all other organs, tissues, and cells and helps our muscles store and use oxygen. Iron is also needed to form many other proteins and enzymes. 

 

To function properly, our bodies need the exact right amount of iron. Too much iron in our bodies can lead to iron poisoning, therefore taking iron supplements can be a risky business. Too little iron, on the other hand, may cause iron deficiency anemia – the most common form of anemia. 

Iron deficiency anemia is a condition in which the blood has insufficient amounts of healthy red blood cells due to too little iron. As a result, the body can’t produce sufficient amounts of hemoglobin and the oxygen can’t get carried throughout the body properly. This may result in fatigue, weakness, and irritability. 

While only 3% of men have iron deficiency, women, especially menstruating and pregnant women, as well as young children are at a particularly high risk of iron deficiency. Studies have shown that 20% of women and a staggering 50% of pregnant women do not have enough iron in their bodies. The most common causes of iron deficiency include blood loss, poor diet, and inability to absorb enough iron from food. 

 

In many cases, iron deficiency can be treated by simply consuming plenty of iron-rich foods. The Daily Value (DV) of iron is 18 mg. However, the amount varies depending on gender and life stage. Men and post-menopausal women, for example only require 8 mg of iron per day. On the other hand, menstruating women need 18 mg a day and pregnant women should intake approximately 27 mg of iron a day. The amount of iron the body absorbs is partially based on the amount of iron you have stored. We must make sure to replace the amount of iron we lose on a daily basis. Fortunately, there are many iron-rich vegetables, even iron-rich fruits, and other healthy foods that contain more than enough iron to meet your daily iron needs. 

 

Top 20 Iron-rich Foods

There are two types of dietary iron – heme and nonheme. Heme iron is derived from hemoglobin and can be found in animal foods, which originally contain hemoglobin. Our bodies can absorb more iron from heme iron food sources, however, these foods should be consumed in moderation. 

Nonheme iron, on the other hand, can be found in plant sources. It is added to iron-enriched foods. Our bodies are less effective at absorbing nonheme iron, yet nonheme iron encompasses most of our dietary iron. Moreover, plant iron food sources are considered healthier and can be consumed in larger amounts. 

Heme Iron-rich Foods

Liver And Other Organ Meats

The Best And Healthiest Iron-rich Foods

Organ meats, including liver, kidneys, heart, and brain are extremely high in iron. In fact, research has shown that a 3.5-ounce or 100-gram serving of beef liver contains 6.5 mg of iron, which is 36% of the Daily Value.

Organ meats are also high in protein, vitamin B, copper, selenium, and choline – a nutrient that is vital for proper brain and liver function. The liver is also incredibly high in vitamin A. 

However, organ meats are not appropriate iron-rich foods for pregnancy and should be avoided during all three trimesters. 

Shellfish

The Best And Healthiest Iron-rich Foods

Shellfish are some of the most effective iron-rich foods for anemia. All kinds of shellfish are high in iron, especially oysters, clams, and mussels. A 3.5-ounce or 100-gram serving of clams, for example, contains up to 3 mg of iron, which is 17% of the DV, however, the amount of iron in clams may vary.

Shellfish are very nutritious overall. They are packed with protein, vitamin C, and huge amounts of vitamin B12. Additionally, shellfish have been shown to increase the level of the ‘good’ HDL cholesterol in your blood. 

While certain types of shellfish and fish may contain large amounts of mercury and other toxins, according to a 2012 study, the benefits of eating seafood outweigh the risks considerably. 

Raw shellfish, however, may be contaminated with bacteria and parasites, as such, they should not be consumed during pregnancy. 

Red Meat

The Best And Healthiest Iron-rich Foods

Red meat is an excellent source of iron in food and probably the most accessible source of dietary heme iron. A 3.5-ounce or 100-gram serving of ground beef, for example, contains 2.7 mg of iron and covers 15% of the DV. 

A 1992 study examining iron status in exercising women has found that women who consume meat seem to absorb iron better than those who took iron supplements instead. 

Red meat is also rich in high-quality protein, selenium, zinc, and various B vitamins. 

Fish

The Best And Healthiest Iron-rich Foods

Most fish, especially tuna, sardines, mackerel, haddock, perch, and salmon, are considered healthy, very nutritious, and full of iron. A 3.5-ounce or 100-gram serving of canned tuna, for example, contains approximately 1.6 mg of iron, which is just over 11% of the DV. 

Fish are also packed with omega-3 fatty acids, which offer countless other health benefits, including promoting brain health, strengthening the immune system, and supporting healthy growth and development. Additionally, they are rich in selenium, niacin, vitamin B12, and other essential nutrients. 

Poultry

The Best And Healthiest Iron-rich Foods

Poultry, especially turkey and dark turkey meat is a great source of iron. A 3.5-ounce or 100-gram serving of dark turkey meat contains 1.4 mg of iron, which is 8% of the DV. The same amount of white turkey meat, on the other hand, contains only 0.7 mg (4% of the DV). 

Turkey and other poultry are also packed with healthy protein, selenium, zinc, and several B vitamins. Moreover, consuming poultry and other high-protein foods may make you feel food and increase your metabolic rate after a meal, resulting in weight loss without losing muscle mass. 

Nonheme Iron-rich Foods for Vegetarians

Spinach

When it comes to plant-based nonheme iron-rich foods that are also suitable for vegetarians and iron-rich vegetables, in particular, only a few are as high in iron as spinach. A 3.5-ounce or 100-gram serving of raw spinach contains approximately 2.7 mg of iron, which is 15% of the DV. 

Spinach also offers tons of other health benefits, yet it is low in calories. While spinach contains nonheme iron, which is not as easily absorbed as heme iron, it is rich in vitamin C and as studies have shown that vitamin C considerably boosts iron absorption, the iron-vitamin C combination is particularly healthy and powerful. 

It also contains lots of antioxidants called carotenoids, which have been linked to decreased inflammation, better eye health, and reduced risk of cancer. To make sure the antioxidants get properly absorbed, consume them with healthy fats, such as olive oil

While spinach is the most iron-rich leafy green vegetable, kale, collard, beet greens, and swiss chard all contain large amounts of iron. 

 

Sun-dried Tomatoes

Raw tomatoes contain relatively small amounts of iron. However, dried or concentrated in paste, tomatoes are quite high in iron. Half a cup of sun-dried tomatoes, for example, offers up to 15% of the DV. Half a cup of tomato paste, on the other hand, contains 22% of the recommended daily amount of iron. 

As tomatoes are also rich in vitamin C, iron absorption is increased. 

 

Broccoli

The Best And Healthiest Iron-rich Foods

Broccoli is an exceptionally nutritious food. It is packed with vitamin C – a vitamin that helps the body absorb iron, fiber, vitamin K, folate, and of course, iron. In fact, one cup or 156-grams of broccoli contains 1 mg of iron, which is 6% of the DV.

Like other legumes, soybeans are also packed with iron and as tofu is made of soybeans, it is a great iron-rich food for vegetarians. A half-cup (126 grams) portion comes with 3.4 mg of iron, which makes 19% of the DV. 

In addition to iron, tofu also contains considerable amounts of thiamine, calcium, magnesium, selenium, and other essential nutrients. It also offers 22 grams of protein per serving. Furthermore, it contains isoflavones, which are associated with reduced risk of insulin resistance and heart disease and decreased symptoms of menopause

 

Seeds

The Best And Healthiest Iron-rich Foods

Seeds, especially pumpkin, sesame, hemp, and flaxseeds are very high in iron. In fact, two tablespoons of those seeds contain approximately 1.2-4.2 mg of iron or 7-23% of DV. Two tablespoons of tahini – a paste made of sesame seeds contains 2.6 mg of iron or 14% of DV. Hummus, which is made from tahini and chickpeas has 3 mg of iron per half a cup or 17% of DV.

Ways to Maximize Iron Absorption from Nonheme Iron-rich Foods

As heme iron is more easily absorbed by the body than plant-based nonheme iron, vegetarians and vegans are advised to intake 1.8 times more iron a day than people who eat meat. 

As such, men and post-menopausal women should take 14 mg of iron a day, menstruating women 32 mg a day, and pregnant women 49 mg of nonheme iron a day. 

To maximize iron absorption, you can also incorporate some of the following strategies:

  • Make sure to consume nonheme iron-rich foods with foods that contain large amounts of vitamin C, like citrus fruits, greens, tomatoes, peppers, etc. This may increase iron absorption by up to 300%. 
  • Eating nonheme iron-rich foods with foods rich in lysine (an amino acid), such as legumes and quinoa may also increase iron absorption. 
  • Prepare foods in cast iron cookware, as it can provide 2-3 times more iron. 
  • Soaking, sprouting, and fermenting both grains and legumes can improve iron absorption. 
  • Refrain from drinking coffee or tea with meals, as doing so can decrease iron absorption by 50 to 90%.
