Iron is an essential mineral that plays a critical role in forming healthy red blood cells, which carry oxygen throughout the body. A prolonged deficiency in iron can lead to iron deficiency anaemia, which is characterised by symptoms such as lack of energy, shortness of breath, and headaches. To increase iron in your diet, it is recommended to consume iron-rich foods such as meat, poultry, fish, eggs, leafy green vegetables, and iron-fortified foods. Combining iron-rich foods with those high in vitamin C, like citrus fruits, tomatoes, and peppers, can enhance iron absorption. Additionally, cooking meals in a cast-iron skillet can also increase the amount of iron in your diet.

Iron-rich foods: meat, fish, poultry, eggs, leafy greens, beans, nuts, citrus fruits, and more
Iron is an essential mineral that is a part of haemoglobin, which helps maintain strength and energy by carrying oxygen to all body cells. Iron is also necessary for forming healthy red blood cells. The amount of iron you need each day depends on your sex and age. For instance, pregnant women should have an iron intake of 27mg/day, while adults over 50 years should have 8mg of iron a day.
There are two types of dietary iron: heme and non-heme iron. Heme iron is found in meat, poultry, and fish, and is the form of iron that is most readily absorbed by your body. You absorb up to 30% of the heme iron that you consume. Meat generally boosts your iron levels more than non-heme iron. Non-heme iron is found in plant-based foods such as fruits, vegetables, legumes, and nuts. While foods with non-heme iron are still an important part of a nutritious, well-balanced diet, the iron in these foods won't be absorbed as completely. You absorb between 2% and 10% of the non-heme iron that you consume. However, when you eat heme iron with foods higher in non-heme iron, the iron will be more completely absorbed by your body.
Some iron-rich foods include:
- Meat: Red meat is probably the single most easily accessible source of heme iron, and is important for those prone to anaemia. A 3.5-ounce serving of ground beef contains 2.7 mg of iron, or 15% of the daily value (DV).
- Fish: A 3.5-ounce serving of clams provides 17% of the DV for iron.
- Poultry: Like red meat, poultry is a good source of heme iron.
- Eggs: Eggs are a source of non-heme iron.
- Leafy greens: Spinach, kale, and dandelion are good sources of non-heme iron. About 3.5 ounces of raw spinach contains 2.7 mg of iron, or 15% of the DV. Spinach is also rich in vitamin C, which boosts iron absorption.
- Beans: Legumes are a source of non-heme iron and are also high in folate, magnesium, potassium, and fiber. A cup of cooked lentils provides 37% of the DV for iron.
- Nuts: Macadamia nuts, pistachios, pumpkin seeds, and sesame seeds are good sources of non-heme iron.
- Citrus fruits: These fruits are high in vitamin C, which increases iron absorption.
- Dark chocolate: A 1-ounce serving of dark chocolate contains 3.4 mg of iron, or 19% of the DV.

Iron absorption: cooking in a cast-iron skillet, eating vitamin C-rich foods, and avoiding tea and coffee can all help
Iron is an essential mineral that is part of haemoglobin, which helps maintain strength and energy. It is also necessary for forming healthy red blood cells, which carry oxygen throughout the body. Iron is only available through diet, and deficiency can lead to anaemia, which is quite common.
There are several ways to increase the absorption of iron from foods. One way is to cook with a cast-iron skillet or pot, which can increase the iron content of your food. For example, spaghetti sauce cooked in a cast-iron skillet increased iron content by 2-5mg. This is a good option for those who don't like iron-rich foods, such as spinach and beef, or for vegetarians and those at risk of deficiency, like women and children.
Another way to increase iron absorption is to eat vitamin C-rich foods with your meals. Vitamin C helps increase the absorption of non-heme iron, which is the type of iron found in plant-based foods. Foods rich in vitamin C include citrus fruits, strawberries, tomatoes, and potatoes. You can also try drizzling lemon juice over leafy greens to increase iron absorption.
Finally, it is recommended to avoid tea and coffee with meals, as these can inhibit iron absorption. Tea and coffee contain polyphenols, which have been shown to reduce the absorption of non-heme iron. Instead, have your tea or coffee between meals to maximize iron absorption.

Iron deficiency: symptoms include lack of energy, dizziness, and irritability. Infants, children, and women are at risk
Iron is an essential mineral that is a part of haemoglobin, which helps maintain your strength and
Iron deficiency can lead to a lack of energy, dizziness, and irritability. It can also cause additional symptoms such as shortness of breath, headaches, weight loss, pale skin, and cold hands and feet. In some cases, it may even lead to chest pain, a fast heartbeat, and a craving for non-food items.
Infants, children, and women are particularly at risk of iron deficiency. Infants who were born prematurely or with low birth weight may not get enough iron from breast milk or formula. Children need extra iron during growth spurts, and a well-rounded, varied diet can help prevent iron deficiency. Women are at greater risk due to blood loss during menstruation, which can lead to a lack of iron over time.
To increase iron in your diet, include iron-rich foods such as meat, poultry, fish, eggs, leafy green vegetables, and iron-fortified foods. Mixing lean meat, fish, or poultry with beans or dark leafy greens can improve the absorption of vegetable sources of iron. Additionally, foods rich in vitamin C, such as citrus fruits, strawberries, tomatoes, and potatoes, can enhance iron absorption. Cooking in a cast-iron skillet can also increase the amount of iron in your food.

Iron deficiency is when the body's iron stores are too low. This can be caused by not getting enough iron in your diet, chronic blood loss, pregnancy, and vigorous exercise. If left untreated, iron deficiency can lead to iron deficiency anaemia, which is characterised by a decrease in red blood cells and symptoms such as lack of energy, shortness of breath, headache, irritability, dizziness, and weight loss.
If you are unable to get enough iron from your diet, iron supplements may be necessary. However, it is important to speak to a doctor first before taking any supplements. Iron supplements are typically recommended for pregnant women, infants, and children, who are at a higher risk of iron deficiency or anaemia. For example, newborns receive their iron stores in the uterus, so the mother's diet during pregnancy is crucial. Iron-fortified infant formulas or cereals are often recommended for babies over six months old.
Additionally, vegetarians and women are also at a higher risk of iron deficiency anaemia. Women who menstruate are particularly susceptible due to blood loss. In such cases, a doctor may prescribe iron supplements, but it is important to follow the instructions provided and not self-medicate. Overloading the body with iron can be dangerous, and excess iron accumulation can damage the liver and cause other complications.

Haem/heme and non-haem iron: haem/heme iron is found in meat, poultry, and fish, while non-haem iron
Iron is an essential mineral and plays a vital role in the human body. It is used to make red blood cells, which carry oxygen around the body, and it also contributes to normal cognitive function and energy metabolism. A prolonged deficiency in iron can lead to iron deficiency anaemia, which is the most common cause of anaemia.
There are two different types of iron: haem and non-haem iron. Haem iron is found in meat, poultry, and fish, and is derived from animal proteins. It is more easily absorbed by the body, with an absorption rate of 15-35%. In contrast, non-haem iron is found in plant-based sources, such as grains, beans, vegetables, fruits, nuts, seeds, and fortified cereals and breads, rice, oats, nuts, beans, leafy greens, and dark chocolate. It has a lower absorption rate of 2-20%. The body finds it easier to regulate iron absorption from plant-based foods, so it is important to find the right balance between haem and non-haem iron in your diet.
The amount of iron you need each day depends on your age, sex, and life stage. For example, pregnant women need a higher iron intake of 27mg/day to support the growing baby, while adults over 50 years old should have 8mg of iron per day. People who have periods also need more iron to replace the amount lost in blood during menstruation.
To increase your iron intake, you can consume iron-rich foods such as red meat, offal, poultry, and fish for haem iron, or fortified cereals and breads, rice, oats, nuts, beans, leafy greens, and dark chocolate for non-haem iron. Additionally, vitamin C can help improve iron absorption, so eating iron-rich foods with citrus fruits, strawberries, tomatoes, or potatoes can be beneficial. Cooking meals in a cast-iron skillet can also increase the amount of iron in your food.
