10 iron-rich foods for vegetarians

Introduction

Iron plays a crucial role in the proper functioning of our body. Getting it through a balanced diet is essential to avoid any deficiencies, especially for vegetarians and vegans. In this article, we'll summarize the role of iron, the two forms it takes, and where to find it in plant-based foods.

1. The Role of Iron

Iron plays a crucial role in several biological functions essential for the proper functioning of the body. Here are some of its main functions:

1. Oxygen Transport: The most well-known function of iron is its role in the formation of hemoglobin, a protein found in red blood cells. Hemoglobin transports oxygen from the lungs to the tissues and organs, enabling cellular respiration.
2. Oxygen Storage: Iron is also present in myoglobin, a protein that stores oxygen in muscles. This allows muscles to function efficiently during physical activity.
3. Immune System Function: Iron is involved in the body’s immune response. It participates in the production of immune cells and the fight against infections.
4. Energy Production: Iron is necessary for the production of ATP (adenosine triphosphate), the main energy source used by cells. It plays a role in the respiratory chain, where oxygen is used to produce energy.
5. DNA Synthesis: Iron is essential for DNA synthesis, the genetic material present in all cells. It helps with cell division and growth.

What are the daily iron needs?

The daily iron recommendations vary depending on age, sex, and certain physiological conditions. Here's a general overview of the recommended daily iron intake:

• Adult men: 1 to 2 mg per day
• Adult women: 2 to 4 mg per day
• Pregnant women: 6 mg per day

It's important to note that iron needs can vary from person to person based on factors such as general health, physical activity, the presence of certain medical conditions, and other factors.

Additionally, since iron absorption is low, more must be consumed to ensure adequate intake.

The 2 forms of iron

There are two main forms of iron in food, each with its own absorption characteristics and food sources:

1. Heme iron: This is the form of iron found in animal-based foods, such as meat, poultry, and fish. Heme iron is better absorbed by the body than non-heme iron. It is often associated with hemoglobin and myoglobin, proteins responsible for transporting and storing oxygen.
2. Non-heme iron: Found primarily in plant-based foods, such as cereals, legumes, dried fruits, and vegetables. Non-heme iron is less well absorbed by the body than heme iron. However, certain dietary practices, such as consuming vitamin C sources with meals, can improve its absorption.

3. The 10 Iron-Rich Foods

Here’s a list of iron-rich foods suitable for vegetarians and vegans:

• Quinoa
• Red and white beans
• Soy
• Spelt
• Chickpeas
• Buckwheat
• Rye
• Lentils
• Unsweetened cocoa powder
• Tahini

Other foods that are also a good source of iron include:

• Nori and kombu seaweed
• Fresh parsley
• Spirulina
• Brewer’s yeast
• Poppy seeds, sesame
• Flax and sunflower seeds
• Brazil nuts
• Dried apricots
• Raw spinach

These alone may not provide optimal iron levels daily, so it’s very important to diversify your diet as much as possible every day.

4. How to Increase Iron Levels

Since plant-based iron is less well absorbed than animal-based iron, here are some tips to increase your iron levels:

1. Regularly monitor iron stores through blood tests.
2. Pair plant-based iron with natural vitamin C:
   • Vitamin C improves the absorption of non-heme iron. Combine vitamin C-rich foods (such as citrus, strawberries, peppers) with plant-based iron sources to maximize absorption efficiency.
3. Avoid absorption inhibitors:
   • Certain foods and drinks can hinder iron absorption. Avoid consuming tea, coffee, milk, and dairy products along with meals rich in iron, as these substances can inhibit iron absorption.
4. Cook in cast iron utensils:
   • Cooking in cast iron can increase the iron content of foods, especially in acidic liquid dishes like tomatoes.
5. Avoid calcium supplements at the same time as iron:
   • Calcium can hinder iron absorption, so it's recommended not to take calcium supplements at the same time as iron supplements.
6. Manage gastrointestinal disorders:
   • If you have digestive issues or intestinal permeability, consult your healthcare provider to determine the best way to take iron supplements without causing discomfort.
7. Avoid excessive tea and coffee:
   • Limit your consumption of tea and coffee, especially between meals, as these drinks may contain compounds that reduce iron absorption.
8. Iron supplements:
   • If iron deficiency is severe, your healthcare provider may recommend iron supplements. However, self-administering iron supplements without medical advice can be dangerous, as excess iron can be toxic.

Conclusion

Maintaining adequate iron levels is essential for optimal health, especially for vegetarians and vegans. By incorporating iron-rich foods and following our tips, you can not only prevent deficiencies but also promote a healthy and energetic life.
