Iron deficiency, also known as iron deficiency anaemia, is a common problem that occurs when your body does not have enough iron to form healthy red blood cells. This can lead to fatigue, weakness, dizziness, and other symptoms. To combat iron deficiency, it is important to include iron-rich foods in your diet, such as meat, poultry, seafood, beans, and green leafy vegetables. In addition, eating vitamin C-rich foods alongside iron-rich foods can enhance iron absorption. However, certain foods and drinks, such as tea, coffee, calcium-rich foods, and soy proteins, can inhibit iron absorption. For those with severe iron deficiency, dietary changes may not be enough, and iron supplements or medical treatments may be necessary.

What You'll Learn
Include iron-rich foods such as meat, eggs, and leafy greens
Iron deficiency, and the resulting iron deficiency anaemia, is a common nutritional problem, especially for vegetarians and pregnant women. It can be caused by a poorly balanced diet, chronic blood loss, and an increased need for iron due to exercise or pregnancy. To combat this, it is important to include iron-rich foods in your diet, such as meat, eggs, and leafy greens.
Meat is a great source of iron, and including lean red meat in your diet 3 to 4 times a week can help prevent iron deficiency. If you are a vegetarian or vegan, you can still get iron from plant-based sources, but you may need to increase your intake of iron-rich, plant-based foods to absorb the same amount of iron as someone who eats meat. Examples of iron-rich, plant-based foods include dried beans, lentils, chickpeas, canned beans, and green, leafy vegetables.
Eggs are another good source of iron, especially for vegetarians and vegans. They are a complete protein source and are also rich in other essential nutrients like choline and vitamin B12.
Leafy green vegetables, such as spinach, kale, and broccoli, are also excellent sources of iron. They are also rich in other essential nutrients like vitamins C and K, and fibre, which can help improve iron absorption.
In addition to including iron-rich foods in your diet, you can also enhance your body's absorption of iron by eating iron-rich foods alongside those rich in vitamin C. For example, you could squeeze lemon or lime juice over your leafy greens or have a glass of orange juice with your meal.

Consume vitamin C to improve iron absorption
Consuming vitamin C is a great way to improve iron absorption in the body. Vitamin C is the only dietary constituent other than animal tissue that has been shown to promote the absorption of non-heme iron in humans. It is a powerful enhancer of non-heme iron absorption and can reverse the inhibiting effect of substances such as tea and calcium phosphate.
Non-heme iron is the major dietary source of iron, and its absorption is greatly influenced by meal composition. For example, the presence of calcium and phosphorus in a meal can reduce the absorption of non-haem iron. However, vitamin C can counteract this effect and improve overall iron absorption.
Vitamin C can be found in many fruits and vegetables, including oranges, tomatoes, peppers, broccoli, and spinach. Drinking citrus juices, such as orange juice, or including these foods in your diet is a great way to improve iron absorption. Additionally, vitamin C supplements are also available and are often recommended by doctors to help with iron deficiency.
It is important to note that while vitamin C can enhance iron absorption, it is not a substitute for iron-rich foods or supplements in the case of iron deficiency. Iron-rich foods include meat, poultry, seafood, eggs, leafy green vegetables, and iron-fortified foods. In some cases, iron supplements may be necessary to correct iron deficiency, and these should be taken under the guidance of a healthcare professional.
By including vitamin C in your diet and ensuring a sufficient intake of iron-rich foods, you can effectively improve your body's absorption of iron and maintain healthy iron levels.

Avoid calcium-rich foods with iron-rich foods
If you are iron deficient, it is important to include iron-rich foods in your diet, such as meat, poultry, seafood, eggs, beans, and leafy green vegetables. However, it is also important to be mindful of the fact that certain foods can interfere with the absorption of iron.
Calcium-rich foods, in particular, can reduce the absorption of iron, especially plant-based, non-haem iron. Calcium and iron are both essential for a healthy diet, but it is recommended that you do not consume them together. This includes supplements, as well as dietary sources. It is best to space them apart, allowing a gap of 3-4 hours between taking iron and calcium supplements, to ensure you get the full benefits of both.
Calcium-rich foods include dairy products, such as milk, cheese, and yogurt, as well as sardines, seeds, and leafy greens like collard greens and kale. Fortified foods, such as cereals, flour, and cornmeal, are also often rich in calcium.
If you are trying to increase your iron intake, it is advisable to avoid consuming these calcium-rich foods at the same time as iron-rich foods. Instead, focus on pairing iron-rich foods with those that are high in vitamin C, as this can enhance iron absorption.
If you are concerned about iron deficiency, it is important to consult a healthcare professional, who can advise on the best course of action for your specific needs.

Take iron supplements if necessary
Iron deficiency can be caused by a variety of factors, including inadequate dietary intake, blood loss, pregnancy, and certain medical conditions. While it is important to include iron-rich foods in your diet, sometimes this may not be enough, and iron supplements may be necessary to correct the deficiency and achieve healthy iron levels.
Iron supplements are typically recommended for those at greater risk of developing iron deficiency, such as pregnant people, individuals with medical conditions like Crohn's disease, those who have undergone bariatric surgery, and people with heavy menstrual periods. Additionally, those who follow a vegan or vegetarian diet may also need to consider taking iron supplements, as plant-based sources of iron are not as readily absorbed by the body as meat sources.
If you suspect you may have iron deficiency, it is important to consult a healthcare professional for a proper diagnosis and guidance on taking iron supplements. Overloading the body with iron can be dangerous, and iron supplements may interfere with the effectiveness of certain medications. Therefore, it is crucial to follow the advice of a healthcare provider regarding the dosage and form of iron supplement that is most suitable for your specific needs.
Iron supplements come in various forms, including capsules, tablets, chewable tablets, and liquids. The most common type is ferrous sulfate, which is available in tablet and liquid form. Other forms include ferrous gluconate and ferrous fumarate. It is recommended to take iron supplements on an empty stomach, as this enhances absorption. However, some people may experience stomach cramps, nausea, and diarrhea as side effects, in which case taking the supplement with food may be preferable.
It may take one to four weeks after starting an iron supplement to notice improvements in symptoms. To ensure optimal absorption, it is advised to refrain from consuming tea or coffee with meals, avoid eating calcium-rich foods alongside iron-rich foods, and include vitamin C-rich foods in your diet, as vitamin C enhances iron absorption.

Avoid tea and coffee with meals
To treat iron deficiency, it is recommended to include iron-rich foods in your diet, such as meat, poultry, seafood, eggs, beans, and green, leafy vegetables. In addition, consuming foods rich in vitamin C, such as citrus juices, at the same time as iron-rich foods can enhance iron absorption.
However, certain foods and drinks can interfere with the absorption of iron. Tea and coffee are known to inhibit iron absorption, hence the recommendation to avoid consuming them with meals.
Tea contains tannins, a type of polyphenol, which can bind to iron and inhibit its absorption in the body. Coffee, on the other hand, is high in caffeine and polyphenols, which can reduce iron absorption by up to 60% and 76%, respectively. Therefore, drinking tea or coffee with meals can significantly reduce the amount of iron absorbed from food.
By avoiding tea and coffee during meals, you can maximize iron absorption from your diet. This is especially important for individuals with iron deficiency, as they need to ensure optimal absorption to maintain adequate iron levels in their bodies.
It is worth noting that tea and coffee can still be enjoyed in moderation at other times of the day, but it is advisable to separate them from mealtimes, especially if you are aiming to boost your iron intake. For those with severe iron deficiency, consulting a healthcare professional is advised, as they may recommend iron supplementation or other treatments in addition to dietary modifications.
