Calculating Dietary Energy

Science · Organisms & Life Processes · procedural

Calculate and evaluate energy intake and requirements in a healthy daily diet, interpreting food labels and nutritional data

Sign in to track this

What mastery looks like

  • Reads and interprets a nutritional information label (kJ and kcal)
  • Estimates daily energy requirements for a person of a given age/activity level
  • Compares the energy content of different diets and identifies surpluses or deficits

Check your understanding

If Calculating Dietary Energy was reading food labels at the supermarket with you, could they work out roughly whether a meal gives too much, too little, or about the right amount of energy for a day?
