This chapter covers these major long-essay areas:
  1. Micronutrients
    • Definition, role in nutrition, and prevention/management of deficiency disorders.
    • Includes vitamins and minerals such as vitamin A, iron, iodine, zinc, folate, and vitamin D.
  2. Vitamin A deficiency
    • Clinical manifestations, especially xerophthalmia and childhood consequences.
    • India-specific prevention: Vitamin A Supplementation Programme, food-based approaches, fortification, infection control, and nutrition education.
  3. Iodine and iodine deficiency disorders (IDD)
    • Sources and functions of iodine.
    • Full spectrum: goitre, hypothyroidism, miscarriage, stillbirth, congenital anomalies, cretinism, impaired cognition, and reduced work capacity.
    • National Iodine Deficiency Disorders Control Programme and universal salt iodization.
  4. Nutritional problems in public health
    • Undernutrition, protein-energy malnutrition, micronutrient deficiencies, low birth weight, overnutrition, obesity, and diet-related noncommunicable diseases.
  5. Protein-energy malnutrition (PEM)
    • Definition, ecology/epidemiology, causes, classifications, manifestations of marasmus and kwashiorkor, prevention, and control.
  6. Diet in disease
    • Therapeutic dietary principles for common diseases, with a focused note on the relationship between diet and cancer.
  7. Assessment of nutritional status of a community
    • Direct methods: anthropometry, clinical examination, biochemical tests, dietary surveys, and functional assessment.
    • Indirect methods: vital statistics, morbidity/mortality data, ecological indicators, and food-balance data.
    • Merits and limitations of each approach.
At a high level, this chapter links deficient intake, disease, social determinants, and public-health interventions. For long essays, a scoring answer usually follows: definition, burden/epidemiology, causes, clinical features, assessment/classification, prevention, treatment or control programme, and conclusion.
