Introduction<\/strong><\/h2>\n

India faces a high burden of anaemia<\/strong>, especially among women and children. Although iron deficiency is an important cause, it explains only about half of anaemia cases globally<\/strong>. Double-Fortified Salt (DFS)<\/strong>, which combines iron and iodine, is proposed as a convenient intervention. However, its dependence on salt consumption, uncertain effectiveness and possible risks<\/strong> raise concerns. Tackling anaemia requires more than adding iron to food through one intervention<\/strong>.<\/p>\n

Understanding Anaemia and Iron Deficiency<\/strong><\/h2>\n
    \n
  1. Meaning of Anaemia: <\/strong>Anaemia is a condition in which haemoglobin levels fall below normal<\/strong>, reducing the blood’s ability to carry oxygen.<\/li>\n
  2. Iron Deficiency Anaemia: <\/strong>It occurs when the body lacks sufficient iron to produce haemoglobin<\/strong>, making iron deficiency an important cause of anaemia.<\/li>\n
  3. Iron Deficiency and Anaemia Are Different: <\/strong>Globally, roughly half of anaemia cases<\/strong> are attributed to iron deficiency, showing that iron deficiency does not explain every case.<\/li>\n
  4. Evidence from India: <\/strong>The Comprehensive National Nutrition Survey (CNNS, 2016\u201318)<\/strong> found that iron deficiency explained only part of anaemia<\/strong> among Indian children and adolescents.<\/li>\n<\/ol>\n

    Status of Anaemia in India<\/strong><\/h2>\n
      \n
    1. High Prevalence: <\/strong>The fifth National Family Health Survey (NFHS-5) found that more than half of Indian women<\/strong> and about two-thirds of young children<\/strong> are anaemic.<\/li>\n
    2. Iron Deficiency Burden: <\/strong>Around 31% of children under five, 36% of women and 28% of the general population<\/strong> have some degree of iron deficiency.<\/li>\n
    3. Vulnerable Groups: Adolescent girls, pregnant women and young children<\/strong> face greater risks due to menstruation, pregnancy and increased iron requirements during growth.<\/li>\n
    4. Socioeconomic Vulnerability: Low-income rural households<\/strong> face greater risks because access to iron-rich foods, fortified foods and supplements is often limited.<\/li>\n
    5. Maternal and Child Health: <\/strong>Anaemia increases the risk of maternal and child deaths<\/strong> during pregnancy and childbirth, affecting overall health outcomes.<\/li>\n
    6. Cognitive and Educational Impact: <\/strong>Iron deficiency during early childhood can permanently affect brain development<\/strong>, physical growth, energy levels and learning outcomes.<\/li>\n
    7. Economic and Psychological Effects: <\/strong>Anaemia reduces work capacity and productivity<\/strong>, while iron deficiency has also been linked to heart problems and depressive symptoms<\/strong>.<\/li>\n<\/ol>\n

      Government Initiatives and Other Interventions to Address Anaemia<\/strong><\/h2>\n
        \n
      1. Anaemia Mukt Bharat (AMB): <\/strong>The Government distributes iron and folic acid (IFA) tablets<\/strong> through this programme, although coverage and compliance remain challenges<\/strong>.<\/li>\n
      2. 7x7x7 Strategy: <\/strong>India’s revised anaemia strategy includes additional measures beyond existing interventions, recognising the need for a broader approach to anaemia control<\/strong>.<\/li>\n
      3. Fortified Rice Distribution: <\/strong>Iron-fortified rice is distributed through the Public Distribution System (PDS)<\/strong>, Pradhan Mantri Poshan Shakti Nirman (PM POSHAN)<\/strong> and Integrated Child Development Services (ICDS)<\/strong> to reach vulnerable groups.<\/li>\n
      4. Wheat Flour Fortification: Fortify Health<\/strong> partners with mills to add iron, folic acid and vitamin B12<\/strong> to wheat flour, improving access to fortified foods without major behavioural changes.<\/li>\n
      5. Double-Fortified Salt (DFS): <\/strong>DFS contains iron and iodine<\/strong> and is proposed as a convenient way to improve iron intake through a commonly consumed household food item.<\/li>\n<\/ol>\n

        Limitations and Concerns Associated with Double-Fortified Salt<\/strong><\/h2>\n
          \n
        1. Conflict with Salt Reduction Goals: <\/strong>Indians consume roughly twice the World Health Organization (WHO)-recommended five grams of salt daily<\/strong>, while DFS relies on regular salt consumption to deliver iron.<\/li>\n
        2. Risk to Cardiovascular Health: <\/strong>About one in three Indian adults has hypertension<\/strong>, while India’s non-communicable disease (NCD) action plan targets a 30% relative reduction in salt intake<\/strong>.<\/li>\n
        3. Unequal Iron Consumption: Adult men generally consume the most salt<\/strong>, while women and young children consume the least<\/strong>, potentially giving the groups with greatest iron needs smaller doses.<\/li>\n
        4. Risk of Iron Overload: <\/strong>The body has no regulated mechanism to excrete excess iron<\/strong>, which can accumulate, promote oxidative stress<\/strong> and has been linked to metabolic disease<\/strong>.<\/li>\n
        5. Risks in Haemoglobinopathies: <\/strong>People with beta-thalassaemia<\/strong>, particularly those receiving blood transfusions, face greater risks of iron overload; sickle cell disease is concentrated in tribal areas<\/strong>.<\/li>\n
        6. Limited Screening Capacity: <\/strong>The PDS reaches around 800 million people<\/strong>, making individual screening<\/strong> for iron-related risks before nationwide DFS consumption impractical<\/strong>.<\/li>\n
        7. Cumulative Iron Exposure: <\/strong>Fortified rice, IFA tablets and DFS could expose children and adolescents to iron through three or four government programmes simultaneously<\/strong>, without adequate assessment of total intake<\/strong>.<\/li>\n
        8. Poor Iron Absorption: Phytates<\/strong> in cereals and pulses, polyphenols<\/strong> in tea and coffee, and calcium in milk<\/strong> reduce the absorption of non-haem iron<\/strong> from meals.<\/li>\n
        9. Uncertain Household Effectiveness: Cooking losses, uneven dosing and variable diets<\/strong> may reduce actual iron intake, while supervised trials cannot fully reflect household conditions.<\/li>\n
        10. Infection-Related Limitations: <\/strong>Infections and inflammation increase hepcidin levels<\/strong>, which block iron absorption<\/strong> and reduce the effectiveness of fortification in populations with higher infection burdens.<\/li>\n
        11. Evidence of Potential Health Risks: <\/strong>The 2006 Pemba trial in Tanzania<\/strong> associated iron and folic acid supplementation with increased hospitalisations and deaths<\/strong> among children in a malaria-endemic setting; a 2015 Kenyan trial<\/strong> found increased pathogenic gut bacteria and diarrhoea<\/strong> among infants receiving iron-fortified foods.<\/li>\n<\/ol>\n

          Why Iron Alone Cannot Address Anaemia<\/strong><\/h2>\n
            \n
          1. Other Nutritional Deficiencies: Folate and vitamin B12 deficiencies<\/strong> also cause anaemia and are common concerns among vegetarian populations.<\/li>\n
          2. Infectious and Parasitic Diseases: Chronic inflammation, recurrent infections, malaria and hookworm<\/strong> contribute to anaemia through pathways beyond insufficient dietary iron.<\/li>\n
          3. Haemoglobin Disorders: Beta-thalassaemia and sickle cell disease<\/strong> contribute to anaemia and require attention beyond routine iron supplementation or food fortification.<\/li>\n
          4. Other Contributing Factors: Early marriage, pregnancy, adolescent undernutrition and menstrual blood losses<\/strong> increase anaemia risks, while low protein and vitamin A intake<\/strong> add to nutritional deficiencies.<\/li>\n
          5. Dietary Limitations: <\/strong>The Indian diet is often monotonous and low in haem iron<\/strong>, while poor affordability<\/strong> limits access to diverse and nutritious foods.<\/li>\n
          6. Diagnostic Gaps: <\/strong>Haemoglobin testing alone cannot identify the cause of anaemia<\/strong>, while routine testing for ferritin, vitamin B12 and inflammation markers<\/strong> remains limited.<\/li>\n
          7. Weak Programme Monitoring: <\/strong>Digital tracking often counts tests and tablets rather than health outcomes<\/strong>, making it difficult to assess actual improvements in anaemia.<\/li>\n
          8. Neglected Public Health Measures: Deworming, malaria control and water, sanitation and hygiene<\/strong> require greater attention alongside nutritional interventions to address the wider causes of anaemia.<\/li>\n<\/ol>\n

            Way Forward<\/strong><\/h2>\n
              \n
            1. Monitored District-Level Pilots: <\/strong>India should conduct district-level DFS pilots<\/strong> before national expansion, measuring haemoglobin, ferritin and inflammation<\/strong> while monitoring potential harm in malaria-endemic and haemoglobinopathy-prone areas.<\/li>\n
            2. Assess Cumulative Iron Intake: <\/strong>The government should examine iron exposure across existing food fortification and supplementation programmes<\/strong> before introducing additional sources of iron.<\/li>\n
            3. Targeted Food Fortification: <\/strong>Fortification should be targeted rather than universal<\/strong> and use better-absorbed iron forms<\/strong> suited to local dietary patterns.<\/li>\n
            4. Strengthen Diagnostic Facilities: <\/strong>Testing should identify different causes of anaemia through ferritin, vitamin B12 and inflammation markers<\/strong> instead of relying only on haemoglobin measurements.<\/li>\n
            5. Improve Dietary Diversity: <\/strong>Affordable access to eggs, dairy, green leafy vegetables, pulses and millets<\/strong> should improve nutritional intake among vulnerable households.<\/li>\n
            6. Strengthen Infection Control: <\/strong>Greater investment in deworming, malaria control, clean water, sanitation and hygiene<\/strong> can address important non-dietary causes of anaemia.<\/li>\n
            7. Learn from Global Experiences: Peru<\/strong> combined iron supplements, micronutrient powders, cash transfers and regional accountability<\/strong>, while Vietnam<\/strong> used weekly supplementation, deworming and iron-fortified fish sauce<\/strong> alongside dietary improvements.<\/li>\n<\/ol>\n

              Conclusion<\/strong><\/p>\n

              India should address anaemia through accurate diagnosis<\/strong>, targeted supplementation and fortification<\/strong>, diverse diets, infection control<\/strong> and stronger public health services. DFS should not be expanded nationally without monitored pilots<\/strong>, assessment of cumulative iron exposure and evidence of safety and effectiveness. The priority must be better health outcomes<\/strong>, not simply wider distribution of iron.<\/p>\n

              Question for practice:<\/strong><\/p>\n

              Examine the causes of anaemia in India and discuss why iron fortification alone cannot effectively address the problem.<\/p>\n
