Nutrition

1. Understanding nutrition as a public health issue

Nutrition concerns the intake and utilisation of nutrients needed for growth, immunity, bodily function and health. Malnutrition includes deficiencies, excesses and imbalances of energy or nutrients. Undernutrition is therefore only one component. Micronutrient deficiencies, sometimes called hidden hunger, can exist even when calorie intake is adequate. Overweight and obesity increase the risk of diabetes, cardiovascular disease and other non-communicable diseases.

Stunting means low height for age and reflects cumulative growth deprivation. Wasting means low weight for height and often reflects recent weight loss or failure to gain weight. Underweight means low weight for age and can reflect stunting, wasting or both. For children below five, these indicators ordinarily use values below minus two standard deviations of the WHO Child Growth Standards median. Severe acute malnutrition also requires attention to mid-upper-arm circumference and bilateral pitting oedema.

Nutrition is both an outcome and a determinant of development. Maternal undernutrition, anaemia and inadequate antenatal care increase risks of adverse pregnancy outcomes. Poor childhood nutrition can impair learning, productivity and resistance to infection. However, population-level associations should not be used to label an individual child’s potential as permanently fixed: timely care and supportive environments remain essential.

• Nutrition-specific interventions address immediate needs, such as breastfeeding support, complementary feeding and micronutrient supplementation.
• Nutrition-sensitive interventions address underlying determinants through agriculture, sanitation, education, social protection and women’s empowerment.

2. India’s burden and its social determinants

NFHS-5 showed improvement over NFHS-4 in child stunting, wasting and underweight, but the levels remained high. Stunting declined from 38.4% to 35.5%, wasting from 21.0% to 19.3%, and underweight from 35.8% to 32.1%. In contrast, measured anaemia increased among both young children and women. These are survey-period estimates, not real-time prevalence figures. Anaemia also has multiple causes, including iron deficiency, other nutrient deficiencies, infections and inherited blood disorders.

Poverty limits access to diverse diets, while unequal intra-household allocation can disadvantage women and girls. Early marriage, adolescent pregnancy, inadequate birth spacing and heavy workloads compound maternal nutritional risks. Scheduled Tribe populations, migrants, remote habitations and urban informal settlements may face overlapping disadvantages in food access, healthcare and service continuity. National averages conceal substantial state, district and socioeconomic differences.

Food availability does not guarantee nutrient absorption. Recurrent diarrhoea, unsafe water, poor sanitation and infections can aggravate undernutrition; undernutrition in turn increases vulnerability to infection. Meanwhile, urbanisation, aggressive marketing, sedentary lifestyles and affordable energy-dense foods are increasing overweight and obesity. Policy must therefore improve dietary quality rather than simply maximise calorie supply.

• A cereal-heavy diet may meet energy needs but provide insufficient protein diversity, iron, zinc and other nutrients.
• Climate shocks, food-price inflation and seasonal livelihood insecurity can reduce consumption of pulses, vegetables, fruits and animal-source foods.

3. Constitutional foundations and programme architecture

Article 21’s protection of life has informed judicial recognition of food and health-related entitlements, while Articles 39(e), 39(f) and 47 support protection of children and nutritional well-being. Public health is primarily a State List responsibility, but nutrition programmes depend on Union financing, national standards and state and local implementation. The National Food Security Act, 2013 gives a statutory foundation to specified food and nutritional entitlements.

The Act provides for nutritional support to pregnant women and lactating mothers, age-appropriate meals for children through anganwadis, and school meals for eligible children up to Class VIII or the relevant statutory age limit. It also provides a maternity benefit of not less than ₹6,000, subject to its provisions. This statutory entitlement should be distinguished from the operational eligibility and payment rules of individual maternity schemes. Food security under the public distribution system is important but does not by itself ensure a balanced diet.

Integrated Child Development Services, launched in 1975, established the anganwadi platform. Its nutritional components now operate within Mission Saksham Anganwadi and POSHAN 2.0, alongside related service restructuring. POSHAN Abhiyaan, launched in 2018, emphasised convergence, community mobilisation, growth monitoring and technology-supported implementation. PM POSHAN supports cooked meals in government and government-aided schools, including eligible Balvatika and Classes I–VIII coverage under scheme guidelines.

• Anaemia Mukt Bharat uses a life-cycle approach combining supplementation, deworming, behaviour change, testing and treatment, fortified foods and attention to non-nutritional causes.
• The National Health Mission supports maternal and child health services, village health and nutrition activities, and referral and treatment systems.
• The Ministry of Women and Child Development, Ministry of Health and Family Welfare, Ministry of Education and food departments must coordinate rather than function as separate delivery silos.

4. A life-cycle package of effective interventions

Prevention should begin before pregnancy through adolescent nutrition, anaemia management, reproductive healthcare and delayed early marriage. During pregnancy, balanced diets, appropriate supplementation, antenatal care and maternity protection are important. After birth, early initiation of breastfeeding, exclusive breastfeeding for the first six months, and timely introduction of adequate complementary foods at six months should be supported, with continued breastfeeding to two years or beyond.

Young children need age-appropriate meal frequency, dietary diversity, responsive feeding, immunisation and prompt management of illness. Growth monitoring is useful only when accurate measurement triggers counselling, assessment and follow-up. Children with severe wasting or nutritional oedema require clinical assessment; medical complications determine the need for facility-based care. Community management must follow applicable protocols and maintain referral links, rather than treating supplementary feeding as a substitute for medical evaluation.

For schoolchildren and adults, public procurement can encourage diverse, locally acceptable menus using pulses, vegetables, millets and suitable protein sources. Fortification can improve micronutrient intake where justified, but requires quality assurance and monitoring. It cannot replace diet diversity or diagnosis of anaemia’s causes. Preventing obesity additionally requires clear food information, healthier institutional meals, physical activity and regulation of misleading marketing.

• Protect infant feeding from inappropriate commercial influence; India’s Infant Milk Substitutes Act, 1992, amended in 2003, regulates promotion of covered products.
• Design menus around nutritional adequacy, safety and cultural acceptability; millets are useful options, not a universal cure for malnutrition.

5. Governance gaps and priorities for reform

Implementation weaknesses include vacancies, uneven worker training, poor anganwadi infrastructure, delayed supplies and excessive reporting burdens. Anganwadi workers, ASHAs and auxiliary nurse midwives need clear responsibilities, adequate support and coordinated supervision. Digital platforms such as Poshan Tracker can support monitoring, but device problems, connectivity gaps and authentication failures must not become grounds for denying eligible beneficiaries nutrition services.

Accountability should move beyond expenditure and meal counts to service quality, diet diversity, timely referrals and equitable coverage. Routine administrative data enable local action, while representative surveys assess population outcomes; the two are not interchangeable. Reliable anthropometry, transparent procurement, food testing, grievance redressal and community oversight are essential. Social audits should examine exclusion, discrimination and menu quality as well as leakage.

A practical reform agenda combines universal access to core services with additional support for high-burden areas and vulnerable groups. District planning should integrate nutrition, drinking water, sanitation, health and livelihoods. Predictable financing, maternity protection and women’s control over resources address structural causes. Nutrition policy succeeds when households can obtain and use healthy diets consistently, not merely when a programme distributes a prescribed quantity of food.

• Track disaggregated outcomes by sex, location and socioeconomic group while protecting personal data.
• For GS-II answers, connect rights, welfare delivery, federal coordination and frontline capacity with measurable health outcomes.
