Kids' Nutrition

The first 1,000 days — from conception to age two — set the trajectory for a child's cognitive development, immune function, and long-term metabolic health. India's NFHS-5 data reveals that 35% of under-fives are stunted and 19% are wasted — numbers that represent nutritional deficiency during critical developmental windows that cannot be fully reversed later.

The micronutrients where Indian children are most commonly deficient are predictable: iron (particularly in exclusively breastfed infants after 6 months), zinc (critical for immune function and growth), vitamin D, iodine, and B12 in vegetarian households. These guides cover safe supplementation ranges by age group, signs of deficiency versus normal variation, how to increase nutrient density in Indian children's meals, and which fortified foods actually deliver what they claim on the label.

School-age children (6–14 years) face a different nutritional challenge — the tiffin box and school canteen replace full parental control over food intake. NFHS-5 shows that while stunting rates fall after age 5, wasting and underweight persist across income groups due to poor dietary quality. Iron deficiency anaemia in school-age children directly impairs academic performance — concentration, working memory, and processing speed all decline measurably at serum ferritin below 20 mcg/L, well before haemoglobin drops. B12 deficiency in vegetarian school children is associated with lower cognitive test scores in Indian studies. These are correctable problems.

Supplementation in children requires significantly more caution than in adults. Fat-soluble vitamins (A, D, E, K) accumulate and can reach toxic levels — vitamin D toxicity in children has been reported from high-dose supplementation without monitoring. Safe vitamin D doses for Indian children are typically 400–600 IU/day for infants under 12 months and 600–1000 IU/day for children 1–10 years, with testing-guided higher doses only under medical supervision. Iron supplementation in non-anaemic children should not be given prophylactically without confirmed deficiency. Zinc supplementation during acute diarrhoea (10–20mg daily for 10–14 days) has strong WHO evidence for reducing severity and duration — one of the most evidence-backed interventions in paediatric nutrition and still under-utilised in Indian primary care.

India's food fortification program covers rice, wheat flour, edible oil, milk, and salt with key micronutrients under FSSAI's +F mark program. The program is genuinely effective when fortified food reaches target populations through PDS and school meal programs. However, commercial "health foods" marketed to parents — malt-based drinks claiming to support growth — typically contribute primarily energy from sugar, with micronutrient levels achievable far more cheaply through real food or a basic multivitamin. These guides separate evidence-based fortification from marketing-driven health claims.
