Iron is a vital mineral that plays a crucial role in numerous bodily functions, most notably in the production of red blood cells. These cells are responsible for carrying oxygen from the lungs to the rest of the body. Understanding “What Food Iron” encompasses is essential for maintaining optimal health and preventing iron deficiency.
Why is Iron Important?
Iron’s primary function is in the creation of hemoglobin, the protein in red blood cells that binds to oxygen. Without sufficient iron, the body cannot produce enough healthy red blood cells, leading to iron deficiency anemia. This condition can cause fatigue, weakness, shortness of breath, and other health issues.
Excellent Food Sources of Iron
Knowing what food iron sources are available is key to preventing iron deficiency. Here’s a detailed look at some of the best dietary sources:
-
Liver: Liver is a particularly rich source of iron.
However, it’s important to note that pregnant women should avoid liver due to its high vitamin A content.Alt text: Raw beef liver, a rich source of heme iron, displayed on a butcher paper.

Red Meat: Beef, lamb, and other red meats are excellent sources of heme iron, a type of iron that is easily absorbed by the body. It is important to limit the amount of red and processed meat due to the probable link with bowel cancer.
-
Beans: Legumes like red kidney beans, edamame beans, and chickpeas are good sources of non-heme iron, a type of iron found in plant-based foods.

Nuts: Many nuts, such as almonds, cashews, and walnuts, contain iron. Incorporating nuts into your diet can contribute to your daily iron intake.
-
Dried Fruit: Dried apricots, raisins, and other dried fruits offer a concentrated source of iron.

Fortified Breakfast Cereals: Many breakfast cereals are fortified with iron, making them a convenient way to boost your iron intake. Check the nutrition label to see how much iron a serving provides.
-
Soy Bean Flour: This flour can be used in baking and cooking as a source of iron.
Recommended Daily Iron Intake
The amount of iron you need varies depending on your age, sex, and overall health. Here are the general guidelines:
- Men (19+ years): 8.7mg per day
- Women (19-49 years): 14.8mg per day
- Women (50+ years): 8.7mg per day
Women who experience heavy menstrual bleeding may need more iron than the recommended daily intake. Consulting with a healthcare professional or registered dietitian is recommended in such cases.
Potential Risks of Excessive Iron Intake
While iron is essential, taking too much can lead to adverse effects. Side effects of high iron doses (over 20mg) may include:
- Constipation
- Nausea
- Vomiting
- Stomach pain
Extremely high doses of iron can be fatal, especially in children. It is crucial to keep iron supplements out of children’s reach.
Department of Health and Social Care Advice
The Department of Health and Social Care recommends obtaining iron through a varied and balanced diet. If you take iron supplements, avoid exceeding the recommended daily intake unless advised by a healthcare provider.
Generally, taking 17mg or less of iron supplements daily is unlikely to cause harm. However, always follow the guidance of a GP or healthcare professional regarding iron supplementation.
Maximizing Iron Absorption
The type of iron in food impacts how well it’s absorbed. Heme iron, found in animal products, is more easily absorbed than non-heme iron, found in plant-based foods. You can enhance the absorption of non-heme iron by:
-
Consuming Vitamin C-Rich Foods: Eating foods high in vitamin C, such as citrus fruits, bell peppers, and strawberries, alongside iron-rich plant-based foods can significantly improve iron absorption.
-
Avoiding Certain Foods and Drinks: Some foods and drinks can inhibit iron absorption, including coffee, tea, calcium-rich foods (like dairy), and foods high in phytates (like legumes and grains).
Conclusion
Understanding what food iron sources are available and how to optimize iron absorption is crucial for maintaining good health. By incorporating a variety of iron-rich foods into your diet and being mindful of factors that can affect iron absorption, you can ensure that your body has the iron it needs to function properly. If you suspect you have an iron deficiency, consult with a healthcare professional for personalized advice and treatment.
