Iron-Rich Foods: The Top 10 with the Highest Content

Iron-rich foods should not be missing from any healthy, balanced diet, since they provide the body with a valuable mineral that is essential for its proper functioning. However, iron deficiency is a very common problem worldwide, and many people fail to get the necessary amount through their diet.

If you also have low iron levels, or simply want to enrich your diet, we’re sharing with you which foods contain the most iron, and how you can include them in your daily routine. Let’s take a look!

What is iron?

Iron is a very important mineral for the body. It is a key component of hemoglobin and helps transport oxygen throughout the body via red blood cells. Beyond oxygen transport, iron also:

• Contributes to energy production and activates metabolism
• Plays a role in collagen synthesis, an important protein for skin, hair, and nails
• Supports proper immune function

What are the forms of iron?

There are two forms of iron found in food: heme and non-heme.

Heme iron (ferrous)
Found in animal foods such as red meat and poultry, heme iron is absorbed more easily by the body.

Non-heme iron (ferric)
Found in plant-based foods like legumes and spinach, non-heme iron is harder to absorb since it first needs to be converted into heme iron.

How much iron do I need daily?

The recommended daily intake of iron is 18 mg. However, exact needs depend on gender, age, and life stage. For example, women are advised to get more iron during pregnancy, but less after menopause.

Here are the top iron-rich foods you can add to your diet today:

4. Pumpkin seeds – 2.7 mg/100 g
   A nutritious topping for yogurt or porridge, pumpkin seeds are rich in iron, magnesium, vitamin K, and zinc.
5. Spinach – 2.7 mg/100 g
   Excellent source of non-heme iron, spinach is one of the best vegetables for those looking for iron-rich foods besides meat. It also contains vitamin C, which helps enhance iron absorption.
6. Lentils – 3.3–3.5 mg/100 g
   Lentils are a top plant-based source of iron, also offering magnesium, folate, potassium, and B vitamins.

How can I improve iron absorption?

As mentioned earlier, non-heme iron from plant foods isn’t absorbed as easily as heme iron. That’s why it’s best to combine plant-based sources of iron, such as legumes, with vitamin C. This can be done simply by adding lemon, bell peppers, or tomatoes to your meals.

Additionally, avoid consuming iron-rich foods together with coffee, tea, or calcium-rich foods such as dairy, since these can inhibit absorption.
