Nutrition Is a Population System
Nutrition: ICMR-NIN 2020 RDA and EAR, first 1,000 days, life-stage requirements, PEM, micronutrient deficiencies and Indian nutrition programmes for NEET-PG.
Nutrition is treated as a population system, covering nutrient sources, ICMR-NIN 2020 recommended dietary allowances, life-stage requirements, deficiency disorders and India's nutrition programmes.
High-yield lines
- The ICMR-NIN 2020 Recommended Dietary Allowances are the Indian standard reference and replaced the 2010 report.
- The Recommended Dietary Allowance equals the Estimated Average Requirement plus two standard deviations, covering about 97.5 percent of the healthy population.
- Carbohydrates should provide about 50 to 60 percent of total energy, proteins 10 to 15 percent and fats 20 to 30 percent.
- The protein RDA for a sedentary adult is about 0.83 grams per kilogram per day under ICMR-NIN 2020.
- The first 1,000 days from conception to the second birthday are the window of greatest nutritional vulnerability and impact.
- Exclusive breastfeeding is recommended for the first six months, with complementary feeding introduced thereafter.
- NFHS-5 reported anaemia in 59.1 percent of adolescent girls aged 15 to 19 years.
- Weekly Iron and Folic Acid Supplementation and deworming under Anaemia Mukt Bharat target adolescents.
- Vitamin A deficiency is the leading preventable cause of childhood blindness and is addressed by prophylaxis.
- Iodine deficiency disorders are prevented through the National Iodine Deficiency Disorders Control Programme using iodised salt.
- Protein energy malnutrition includes marasmus, kwashiorkor and marasmic-kwashiorkor.
- The POSHAN Abhiyaan and Integrated Child Development Services are core Indian nutrition programmes.
- Tea taken with meals reduces non-haem iron absorption by roughly 60 to 70 percent.
- Nutritional status is assessed by anthropometry, biochemical tests, clinical signs and dietary survey.

Frequently Asked Questions
What is the reference standard for nutrient requirements in India?
The ICMR-NIN 2020 Recommended Dietary Allowances, which introduced Estimated Average Requirements alongside RDAs and updated values for protein, iron, calcium and other nutrients.
Why are the first 1,000 days important in nutrition?
From conception to the second birthday is the window of maximum nutritional vulnerability and the greatest impact of intervention on growth and development.
How does the RDA relate to the EAR?
The RDA equals the EAR plus two standard deviations, covering about 97.5 percent of the healthy population, and is the target for individuals.
Which programme targets adolescent anaemia in India?
Weekly Iron and Folic Acid Supplementation with deworming under Anaemia Mukt Bharat targets adolescents, among whom NFHS-5 found high anaemia prevalence.
