Key Topics to Revise

1. Classification of Food Groups

  • Food items are broadly divided into three groups based on function: energy giving, body building, and regulatory/protective.
  • There is also a five food group system used for classification.
  • Energy giving foods mainly include cereals, fats, and sugar.

2. Major Food Groups and Their Nutrients

  • Cereals include rice, wheat, ragi, bajra, maize, jowar, barley, rice flakes, and wheat flour.
  • All cereals give the same nutrients: carbohydrates, proteins, vitamin B, iron, and fibre.
  • Cereals are the main source of energy because they are eaten in large quantity.

3. Food Exchange and Food Pyramid

  • Food Exchange means substitution of one food item with another within the same food group so that the nutrients provided are approximately the same.
  • Examples of food exchange include milk or milk products with cereals, or one fruit with another fruit from the same group.
  • Guddi, Arul, and Sugna show food exchange because each breakfast includes a cereal with milk or a milk product.

4. Meal Planning and Family Needs

  • Meal planning must consider age, sex, seasonal availability, weather, occupation, physiological needs, and family income.
  • People eat according to age: babies, children, adolescents, adults, and old persons need different types and amounts of food.
  • A man requires more protein and energy than a woman because his body is more muscular.
