What to Focus On

  • Public nutrition means promoting health and preventing nutrition-related illness in the population.
  • It uses organised, large-scale, multidisciplinary action.
  • It is built on biological and social sciences.

  • Malnutrition strongly affects child survival.
  • Low birth weight can affect growth and health throughout life.
  • Undernutrition is common among pre-school children.

  • India faces undernutrition and overnutrition together.
  • Sedentary lifestyle increases the risk of obesity.
  • Processed and fast foods are often high in energy, sugar, fat, and salt.

Common Mistakes to Avoid

Public nutrition is the same as clinical nutrition and dietetics.

PEM means only low weight, so underweight, stunting, and wasting are the same thing.

Marasmus and kwashiorkor are just two names for the same severe undernutrition condition.
