Top 10 Iron-Rich Foods to Prevent Deficiency & Improve Health

What Makes a Food High in Iron?

Foods are considered high in iron if they provide at least 3 mg of iron per serving, while those with 6 mg or more per serving are excellent sources.

Iron is categorized into two types: heme iron and non-heme iron. Heme iron, found in animal sources, is absorbed efficiently. Non-heme iron in plant-based foods requires vitamin C to improve absorption.

The best foods with iron meet or exceed the 3 mg threshold per serving and are well-utilized by the body.

Top 10 Iron-Rich Foods to Add to Your Diet

Including high iron foods in your meals helps maintain proper iron levels and prevent deficiencies.

If you want to boost your iron levels, these are the top 10 iron-rich foods to include in your diet:

Animal-Based Sources (Heme Iron)

Heme iron, found in animal foods, is absorbed more efficiently than plant-based iron. Specifically, the body can absorb up to 35% of heme iron at any time.

Red meat is one of the most reliable sources of heme iron as it is readily available.

A 100-gram serving of beef provides about 2.7 mg of iron. It is also rich in protein, zinc, selenium, and B vitamins.

Consuming liver and organ meat provides 6.5 mg of iron per 100 grams. This makes them an excellent source of heme iron. The liver is also packed with vitamin A and other essential nutrients.

Shellfish are also some of the top sources of iron. Clams, in particular, contain up to 28 mg per 100 grams. This is more than the daily requirement for most people.

Clams are also high in potassium and vitamin B12.

Dark meat contains more iron than white meat. It provides about 1.4mg of iron per 100g of dark turkey meat, which you'll find in the thigh area.

This turkey food supplies about 8% of the daily requirement of iron.

While egg yolks contain 0.8 mg of iron per yolk, the absorption rate is lower due to other compounds in eggs that inhibit iron uptake. However, they still contribute to overall intake.

Plant-Based Sources (Non-Heme Iron)

Non-heme iron comes from plant-based foods. While the body absorbs it at a lower rate, pairing it with vitamin C can significantly improve absorption.

These plant-based high iron foods are excellent choices for vegetarians.

A 100-gram serving of lentils provides about 3.3 mg of iron. In addition to that, soaking or sprouting legumes can help reduce compounds that block absorption.

Soy-based foods are some of the best plant-based options. Tofu contains about 5.4 mg of iron per 100 grams, which makes it an iron-rich addition to vegetarian and vegan diets.

It is also a rich source of other minerals such as calcium, copper, and manganese

Spinach provides 2.7 mg of iron per 100 grams and contains oxalates, which reduce absorption.

Eating it with vitamin C-rich foods, like tomatoes or bell peppers, helps the body use the iron more effectively.

A grain that is naturally high in iron and also provides complete protein. A 100-gram serving of quinoa contains about 1.5 mg of iron. This makes it a nutritious alternative to traditional grains.

Pumpkin seeds are one of the top iron-rich plant foods. It provides about 8.52 mg per 100 grams consumed.

Though in smaller amounts, nuts like cashews and almonds also contribute to daily intake.

Foods That Hurt Iron Levels

Certain foods make it difficult for the body to absorb iron. Even when eating foods with iron, pairing them with the wrong ingredients can reduce how much the body actually uses.

Here's a list of them:

When calcium and iron are present in the digestive tract simultaneously, the absorption processes compete. This results in less iron absorbed by the body.

Dairy products like milk, cheese, and yogurts are high in calcium and can interfere with the body’s ability to absorb iron from both heme and non-heme sources.

Tannins in tea and coffee bind to iron, which makes it harder for the body to absorb. This is especially true for non-heme iron from plant-based sources.

Phytates, found in whole grains, beans, and lentils, block iron uptake. Since these foods are also good plant-based sources of iron, proper preparation methods like soaking, sprouting, or fermenting can reduce phytate levels and improve absorption.

How Much Iron Do You Need?

Iron needs vary based on age, gender, and specific conditions. Some need more iron to keep up with their body's demands due to factors like growth, menstruation, or pregnancy.

Here’s a quick breakdown of how much iron you should aim for daily:

• Infants & Children (7 months - 13 years): 7–11 mg
• Teen Boys (14–18 years): 11 mg
• Teen Girls (14–18 years): 15 mg
• Men (19+ years): 8 mg
• Women (19–50 years): 18 mg
• Pregnant Women: 27 mg
• Postmenopausal Women & Elderly: 8 mg

Getting enough iron is easier when you include foods that are rich in iron in your diet. For example, just 100g of beef liver packs 6.5 mg of iron, while a cup of cooked lentils provides 6.6 mg.

If you have higher iron needs (like during pregnancy), you may include multiple sources throughout the day to hit your target.

How to Boost Iron Absorption

Eating foods high in iron is important, but how the body absorbs iron matters just as much. Certain strategies improve absorption, which ensures the body gets the most out of iron-rich meals.

Pair Iron-Rich Foods with Vitamin C

Vitamin C helps the body absorb non-heme iron more efficiently. You can add citrus fruits, bell peppers, or tomatoes to your meals to increase the amount of iron the body can use.

For example, eating lentils with a squeeze of lemon or spinach with strawberries improves absorption.

Cook with Cast Iron Pans

Cooking in cast iron increases the iron content of food, especially acidic dishes like tomato-based sauces. This is an easy way to add small amounts of iron to meals while preparing foods high in iron.

Avoid Calcium & Iron Together

Calcium blocks iron absorption, so it's best to separate dairy products from iron-rich meals.

For those who need both nutrients, having them at different times of the day helps prevent interference.

Limit Tea & Coffee with Meals

Tannins in tea and coffee reduce iron absorption, especially from plant-based sources.

Drinking these beverages between meals instead of foods high in iron allows the body to absorb more iron from food.

When Should You Take an Iron Supplement?

The best way to get iron is by eating high iron-rich foods, but you can take supplements when diet alone isn’t enough or you have trouble absorbing iron from food. This is especially true for pregnant women, vegetarians, and individuals with anemia. This can help meet the daily requirements.

However, taking too much iron can be harmful. Excess iron builds up in the body, leading to toxicity, digestive issues, and organ damage. Supplements should only be taken under medical guidance.

For best absorption, iron supplements work best on an empty stomach or with vitamin C. However, they can cause stomach discomfort, so some may need to take them with food.
