Prevention of Anemia: Diet, Lifestyle, Screening & Complete Guide

India has been classified as having a severe public health burden of anaemia for over a decade. This affects both women and children. The World Health Organization uses this category when anaemia affects more than 40% of a population.

This is not just a historical classification. Recent national data show anaemia has worsened in India. Around 67% of children aged 6 to 59 months have anaemia. About 57% of women of reproductive age are also affected. Both figures are well above the WHO's threshold for a severe public health burden.

Anaemia can affect anyone, but some people have a much higher risk of developing it. If you belong to any of the following groups, regular anaemia screening or a haemoglobin blood test may help detect low haemoglobin levels early.

• Women with heavy menstrual bleeding : Higher risk of iron deficiency anaemia due to chronic blood loss.

• Pregnant women : Increased iron and folate needs make anaemia during pregnancy more common.

• Young children (especially under 5 years) : Rapid growth increases the risk of low haemoglobin and iron deficiency.

• Teenagers, especially adolescent girls : Growth spurts plus menstruation increase the risk of iron deficiency anaemia.

• Vegetarians and vegans : May be at risk of iron deficiency and/or vitamin B12 deficiency anaemia if diets are not well planned.

• Older adults : More likely to develop anaemia due to chronic diseases, inflammation, or poor nutrient absorption.

• Frequent blood donors : Regular blood donation can lower iron stores and haemoglobin levels over time.

• Endurance athletes : Intense training may increase the risk of sports-related anaemia or iron deficiency (for example, from foot-strike haemolysis, sweating, and gastrointestinal losses).

• People with coeliac disease or inflammatory bowel disease (IBD) : Poor nutrient absorption and/or intestinal blood loss can lead to iron deficiency.

If you fall into one or more of these groups, talk to your doctor about whether a haemoglobin test or anaemia screening is right for you. Early diagnosis can help identify the cause and start the right treatment before symptoms become severe.

Riya, a 28-year-old software engineer, assumed her tiredness came from long working hours. A routine blood test showed severe iron deficiency, caused by heavy menstrual bleeding she had never mentioned to a doctor. Her story is common. Anaemia rarely announces itself. It develops slowly, and most people adjust to feeling tired long before they think to get tested.

Left untreated, anaemia can progress from mild fatigue to serious complications, including strain on the heart, poor pregnancy outcomes, and developmental delays in children. Iron deficiency anaemia ranks among the top ten leading causes of years lived with disability in low- and middle-income countries (World Health Organization Regional Office for South-East Asia, 2017).

Watch for These Symptoms

• Persistent fatigue and weakness : Ongoing tiredness that does not improve with rest or sleep.

• Pale skin, lips, or inner eyelids : Loss of healthy pink colour, especially noticeable on the face and inside the eyelids.

• Breathlessness on mild exertion : Getting easily out of breath while walking short distances or climbing stairs.

• Dizziness or light-headedness : Feeling faint, especially when standing up quickly.

• Brittle nails and increased hair loss : Nails that crack or break easily and more hair shedding than usual.

• Unusual cravings for non-food items (pica) : Strong urges to eat or chew ice, chalk, dirt, or other non-food substances.

• Cold hands and feet : Feeling unusually cold in the extremities even when others feel comfortable.

Anaemia prevention comes down to three things:

• Eat enough iron and blood-building nutrients.

• Absorb them properly.

• Address the reason you are losing iron.

All three need attention together. Diet alone will not correct anaemia caused by an untreated infection or heavy blood loss. Supplements alone will not work if your diet is reducing iron absorption.

Eat: Nutrients That Build Red Blood Cells

A balanced anaemia diet is the foundation of healthy haemoglobin levels. It should include iron-rich foods along with vitamin B12 and folate. If iron deficiency is confirmed through a blood test, your doctor may also recommend iron supplements.

Iron-rich foods

• Haem iron (more easily absorbed): Lean red meat, poultry, fish, and eggs.

• Non-haem iron: Lentils, beans, spinach and other dark leafy greens, pumpkin seeds, ragi, jaggery, and iron-fortified cereals.

Vitamin B12

Needed to produce healthy red blood cells. Found in dairy products, eggs, meat, fish, and fortified plant-based milk. Strict vegetarians and vegans are at higher risk of deficiency.

Folate (Vitamin B9)

Also essential for red blood cell production. Found in dark green leafy vegetables, citrus fruits, kidney beans, and wholegrains.

Absorb: Optimise How Your Body Uses What You Eat

Eating iron-rich food is only half the equation. How you eat it changes how much iron your body actually absorbs.

• Pair iron-rich meals with vitamin C-rich foods, such as citrus fruits, tomatoes, amla, guava, or peppers

• Avoid tea, coffee, and calcium-rich foods or drinks alongside iron-rich meals

• Take calcium and iron supplements at different times of the day

• Cook in cast-iron cookware, which can modestly increase the iron content of food

If you want to raise iron levels quickly, oral or intravenous (IV) iron may be used clinically, but only after a blood test confirms iron deficiency. Iron supplements should only be started after appropriate testing and medical advice.

Address the Underlying Medical and Environmental Causes

Prevention of iron deficiency anaemia involves more than eating iron-rich foods. Managing heavy blood loss, treating infections, maintaining good sanitation, and getting regular screening are equally important for preventing iron deficiency from developing or recurring.

Doctors generally look at four broad causes of anaemia:

• Not enough iron, vitamin B12, or folate in the diet

• Blood loss from periods, ulcers, haemorrhoids, or other gastrointestinal bleeding, including occult (hidden) digestive bleeding

• Infections and inflammation, including malaria and intestinal worms

• Inherited blood disorders, such as sickle cell disease or thalassaemia

Manage chronic blood loss : Heavy periods, ulcers, and haemorrhoids are common, treatable causes of ongoing iron loss. Anyone with heavy periods should see a doctor, as treatment may include iron supplements or hormonal contraception.

Control infections that silently drain iron : Malaria, worm infections, and chronic infections suppress red blood cell production or cause direct blood loss. Periodic deworming, especially in children and adolescents, helps reduce this risk.

Practise good water, sanitation, and hygiene : Unsafe water increases the risk of diarrhoeal disease and gut inflammation. Both reduce iron absorption. Handwashing, clean toilets, and safe drinking water are genuine anaemia prevention tools.

Get routine screening : A complete blood count (CBC) and ferritin test can detect anaemia before symptoms become severe. This is particularly important for pregnant women, endurance athletes, strict vegetarians, and people with heavy periods.

Ferritin reflects your stored iron. A level below roughly 15 ng/mL is generally considered low. Levels below 10 ng/mL suggest more advanced deficiency. Your doctor will interpret ferritin alongside your full blood results.

Managing anaemia is not just about eating more iron-rich foods. Some foods, drinks, and habits reduce iron absorption, worsen iron deficiency, or delay proper treatment.

• Tea, coffee, and cocoa within an hour of iron-rich meals

• Calcium supplements or dairy taken with iron-rich meals or iron tablets

• High-bran cereals or large amounts of bran with iron-rich meals. Wheat itself is not the problem

• Excessive alcohol

• Taking iron supplements without a blood test

• Ignoring heavy periods, unexplained fatigue, or blood in the stool

• Raw or unwashed food and unsafe water in areas with poor sanitation

There are many myths about anaemia and iron deficiency that can delay diagnosis or treatment. Understanding the facts can help you recognise the symptoms, seek the correct diagnosis, and manage low haemoglobin levels effectively.

Myth: Eating spinach alone cures anaemia.
Fact: Spinach helps, but its iron is non-haem and poorly absorbed. Pair it with vitamin C and address any underlying cause.

Myth: Only women get anaemia.
Fact: Men and children can also develop anaemia, often because of diet, chronic disease, or blood loss unrelated to menstruation.

Myth: Feeling tired always means low iron.
Fact: Fatigue has many causes. Only a blood test can confirm iron deficiency.

Myth: Once you start iron tablets, you're cured immediately.
Fact: Iron stores rebuild gradually. Most people need consistent supplementation for weeks or months before haemoglobin levels improve visibly.

Most anaemia develops slowly and responds well to diet and supplements. However, some symptoms require urgent medical attention rather than a wait-and-see approach.

See a doctor promptly if you notice:

• Severe or worsening fatigue that affects daily activities

• Chest pain or a racing heartbeat

• Fainting or near-fainting episodes

• Pregnancy combined with any symptoms of anaemia

• Blood in the stool or unusually dark, tarry stools

• Breathlessness even at rest

A Practical One-Day Iron-Rich Meal Plan

Following an iron deficiency anaemia diet is one of the most effective ways to restore iron stores and maintain healthy haemoglobin levels. Pairing iron-rich foods with vitamin C-rich foods improves iron absorption and supports healthy red blood cell production.

• Breakfast: Ragi porridge with an orange or guava

• Mid-morning: A handful of soaked almonds

• Lunch: Rajma or lentils, spinach sabzi, and a side of tomato salad

• Evening snack: Roasted chana or pumpkin seeds

• Dinner: Grilled fish or a paneer and dark leafy green curry with a squeeze of lemon

Keep tea and coffee at least an hour away from these meals to maximise iron absorption.

India's National Framework: The Anemia Mukt Bharat 6×6×6 Strategy

India runs the world's largest anaemia reduction programme, Anemia Mukt Bharat (AMB), launched by the Ministry of Health and Family Welfare. Its structure also serves as a useful checklist for individual prevention.

Six target groups

• Children aged 6 to 59 months

• Children aged 5 to 9 years

• Adolescents aged 10 to 19 years

• Women of reproductive age (15 to 49 years)

• Pregnant women

• Lactating women.=

Six interventions

• Prophylactic iron and folic acid (IFA) supplementation

• Periodic deworming with albendazole

• Behaviour change communication using a test–treat–talk approach

• Point-of-care haemoglobin testing followed by targeted treatment

• Mandatory iron- and folic acid-fortified foods in government nutrition programmes

• Screening for non-dietary causes such as malaria, haemoglobinopathies, and fluorosis in endemic areas

Six institutional mechanisms

Inter-ministerial coordination, convergence with schemes such as POSHAN Abhiyaan, a strengthened IFA supply chain, healthcare worker training, a National Centre of Excellence for Anaemia Research, and a digital tracking dashboard.

The programme has since expanded into a 7×7×7 framework, adding low-birthweight babies, an Eating Right dietary approach, and a digitally integrated monitoring mechanism (National Health Mission, n.d.).

If you belong to one of these target groups, many of these services, including IFA supplementation, deworming, dietary counselling, and haemoglobin screening, are already available free of charge at government health centres across India.

Prevention of anaemia in pregnancy requires additional care because iron needs increase as blood volume expands and the baby depends on the mother's iron stores. Daily iron and folic acid supplementation, regular antenatal check-ups, and healthy birth spacing are key preventive measures.

• Iron and folic acid supplementation : Daily IFA tablets, following WHO dosage guidelines, are standard in Indian antenatal care.

• Early and regular antenatal screening : Anaemia should be checked at the first antenatal visit and monitored throughout pregnancy.

• Birth spacing : Waiting at least 24 months between pregnancies gives the body time to rebuild depleted iron stores.

• Delayed umbilical cord clamping : Waiting at least one minute after birth improves a newborn's iron stores.

• Exclusive breastfeeding for six months : Breast milk iron is highly bioavailable, and breastfeeding also naturally supports birth spacing.

Anaemia during pregnancy is linked to a significant proportion of maternal deaths in the region. This is why the WHO places it at the centre of national anaemia prevention strategies (World Health Organization Regional Office for South-East Asia, 2017).

Preventing Sickle Cell Anaemia

Prevention of sickle cell anaemia differs from nutritional anaemia because the condition is inherited. It focuses on carrier screening, genetic counselling, and newborn screening to reduce the risk of passing the condition to future generations.

• Carrier screening : A blood test identifies whether someone carries the sickle cell trait.

• Genetic counselling : If both partners carry the trait, each pregnancy has a 25% chance of the child having sickle cell disease.

• Newborn screening : Early diagnosis allows preventive care, such as penicillin prophylaxis, to begin before complications develop.

India has an estimated 30 million sickle cell trait carriers, with a national prevalence of around 3.3%, mainly among tribal populations across central India (Dolai, 2024). In 2023, the Government of India launched the National Sickle Cell Anaemia Elimination Mission, aiming to eliminate the condition as a public health problem by 2047.

How is Anaemia Treated?

Treatment depends on the cause identified through blood tests. Broadly, it follows three approaches:

• Correcting nutritional deficiencies through dietary changes.

• Oral or intravenous (IV) iron and vitamin supplementation after confirming deficiency.

• Treating the underlying cause, such as bleeding, infection, or a chronic medical condition.

For inherited disorders such as sickle cell disease or thalassaemia, treatment focuses on long-term disease management. See our dedicated guide on anaemia treatment for more information.

Most anaemia develops gradually, which is exactly why it is easy to overlook. The earlier iron deficiency is detected, the easier it is to treat.

If you have been feeling unusually tired, breathless, or light-headed, do not guess the cause. A simple blood test can often provide the answer and guide the right next step in a single visit.

Prevention begins long before symptoms appear. Knowing your haemoglobin and ferritin levels today can help prevent more serious health problems tomorrow.

Quick Summary

• Eat iron-rich foods with vitamin C

• Keep tea and coffee away from iron-rich meals

• Treat heavy periods or other causes of blood loss

• Get a CBC and ferritin test if you have symptoms

• Do not self-medicate with iron supplements
