Beat Anaemia With a Proper Diet: What to Eat and What to Avoid

Feeling constantly tired, weak, dizzy or short of breath can sometimes be linked to anaemia, a condition in which the body does not have enough healthy red blood cells or haemoglobin to carry oxygen efficiently.

Iron deficiency is the most common nutritional cause of anaemia, but it is not the only one. Anaemia can also result from deficiencies of vitamin B12, folate or vitamin A, as well as blood loss, chronic disease, infections and inherited conditions. For that reason, persistent symptoms should be medically evaluated rather than treated with diet alone.

Foods to Eat More Often

1. Lean Meat

Lean beef and other meats are among the richest sources of heme iron, a form of iron that the body absorbs relatively efficiently.

Adding moderate portions of lean meat to meals can help increase iron intake, particularly for people whose diet is low in iron.

2. Fish and Poultry

Fish, seafood and poultry also provide iron and can contribute to a balanced iron-rich diet.

Animal foods can additionally improve the absorption of non-heme iron found in plant foods when they are eaten together.

3. Lentils, Beans and Peas

Vegetarians and people who eat little meat can obtain iron from:

•    Lentils
•    Chickpeas
•    Kidney beans
•    White beans
•    Peas
•    Other pulses

These foods provide non-heme iron along with protein and fibre.

4. Dark-Green Leafy Vegetables

Vegetables such as spinach, kale and watercress can contribute iron and other useful micronutrients.

The NHS specifically recommends dark-green leafy vegetables as part of a diet designed to increase iron intake.

5. Iron-Fortified Cereals and Bread

Some breakfast cereals, breads and grain products are fortified with iron, making them a convenient way to increase dietary intake.

Check nutrition labels because the amount of added iron varies considerably between products.

6. Nuts and Dried Fruit

Nuts and dried fruits such as raisins, apricots and prunes can provide additional dietary iron.

Because dried fruits are concentrated in natural sugars and calories, portion size still matters.

Don’t Forget Vitamin C

What you eat alongside iron-rich foods matters too.

Vitamin C helps the body absorb non-heme iron, making it particularly useful when meals rely heavily on plant sources of iron.

Good sources include:

•    Oranges and other citrus fruits
•    Strawberries
•    Bell peppers
•    Tomatoes
•    Broccoli
•    Other vitamin C-rich fruits and vegetables

For example, adding tomatoes or peppers to a lentil meal, or having fruit alongside an iron-fortified breakfast, can improve iron absorption.

What Should You Limit Around Iron-Rich Meals?

Certain foods and drinks can make iron harder to absorb when consumed at the same time.

Tea and Coffee

Tea and coffee contain compounds that can reduce iron absorption, particularly from plant-based foods.

If you are trying to improve your iron status, consider having tea or coffee away from your main iron-rich meals rather than immediately with them.

Large Amounts of Milk and Dairy

Calcium can interfere with iron absorption under some circumstances.

You do not necessarily need to eliminate dairy, but someone being treated for iron deficiency may be advised to separate calcium-rich foods or supplements from iron supplements.

Cocoa

WHO guidance also lists cocoa among foods and drinks that can slow iron absorption when consumed with iron-rich foods.

Very High-Phytate Foods at the Same Meal

Phytates found in foods such as bran and some whole grains and legumes can reduce non-heme iron absorption.

That does not mean healthy whole grains or legumes should automatically be avoided. Rather, people with iron deficiency may benefit from paying attention to food combinations and following personalised dietary advice.

A Simple Iron-Friendly Meal Idea

Try combining:

Lentils or lean meat + green vegetables + tomatoes or peppers + a vitamin C-rich fruit

Then enjoy your tea or coffee later instead of immediately with the meal.

This type of meal combines iron-rich foods with ingredients that can help improve iron absorption.

What About Vitamin B12 and Folate?

Not every nutritional anaemia is caused by iron deficiency.

Deficiencies of vitamin B12 and folate can also cause anaemia, meaning simply increasing iron intake may not correct the problem.

A healthcare professional may order blood tests to identify the type and cause of anaemia before recommending treatment.

Should You Take Iron Supplements?

Do not assume that everyone with fatigue needs an iron supplement.

High-dose iron supplements can cause side effects such as nausea and constipation and may interact with certain medicines, including levothyroxine and levodopa.

If blood tests confirm iron-deficiency anaemia, a healthcare professional may recommend iron supplements alongside dietary changes.

When Diet Alone Isn’t Enough

Diet can be important in preventing and managing iron-deficiency anaemia, particularly when inadequate iron intake contributes to the problem.

However, anaemia can also result from heavy menstrual bleeding, pregnancy, gastrointestinal bleeding, infections, inflammation, chronic disease or inherited blood disorders. Treating those cases requires addressing the underlying cause.

Seek medical advice if you experience persistent fatigue, weakness, dizziness, shortness of breath, palpitations or other symptoms that could indicate anaemia.

The Bottom Line

A balanced diet rich in iron, vitamin C and other essential nutrients can support healthy red blood cell production and help prevent nutritional deficiencies.

Focus on iron-rich foods such as lean meat, seafood, beans, lentils, leafy greens and fortified cereals, combine plant-based iron with vitamin C, and avoid routinely drinking tea or coffee alongside iron-rich meals.

Most importantly, remember that anaemia is a medical condition with many possible causes. A proper diagnosis is essential before relying on diet or supplements as treatment.
