Public Health Nutrition

Public Health Nutrition (PHN) addresses the nutritional challenges facing large populations. In India, this involves tackling the 'triple burden' of malnutrition: undernutrition (stunting and wasting), micronutrient deficiencies (like anemia), and the rising tide of overnutrition and obesity. Students learn about the socio-economic factors that drive these issues and the national programs designed to combat them.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Malnutrition only means not having enough food.

    Malnutrition also includes 'hidden hunger' (micronutrient deficiencies) and overnutrition. Using the 'triple burden' framework helps students understand the full spectrum of the problem.

  • Public health programs are only for the very poor.

    While they target vulnerable groups, programs like salt iodization and nutrition education benefit the entire population. Analyzing universal versus targeted interventions helps clarify this.
