Frequently Asked Questions
What are kilojoules?
We measure energy in kilojoules, the same as we measure distance in kilometres and weight in kilograms.
Our bodies use energy for everything we do - growth, development, repair, and for movement activities like walking, running, swimming, working and even sleeping.
The pre-metric name for kilojoules was calories, but for over 30 years Australia has used the metric terminology: kilojoules.
1 kilojoule = 0.24 kilocalories (often called Calories)
1 kilocalorie = 4.18 kilojoules
kcal kilocalorie (or Calorie)
What are nutrients?
The nutrients found in all foods and drinks provide nourishment for the body. This nourishment is in the form of:
- Substances which provide energy
- Building blocks for bone, muscle, organs, hormones and blood
- Substances needed for processes to occur in the body, like digestion
- Substances that protect the body
Nutrients are drawn from a wide variety of foods and the more varied your diet, the more likely you are to obtain all the nutrients you need.
- Protein - made up of amino acids
- Fat - saturated, polyunsaturated (Omega 3 and 6) and monounsaturated
- Carbohydrate - includes starches and sugars
- Vitamins and minerals - play many crucial roles in the body's function and wellbeing, but do not provide energy (kilojoules)

What is my Daily Intake?
Your personal daily intake needs depend on a number of factors including how active you are and how much energy you burn during the day. An Accredited Practising Dietitian can provide you with expert individual nutrition advice on a range of health conditions and help you tailor a nutrion plan that is best suited to your lifestyle.
What is food energy?
Food energy is the amount of energy obtained from food that is available through cellular respiration. Carbohydrates, fiber, fats, sugars, proteins and other nutrients all release energy during respiration - this is often called 'food energy'. When the food (providing fuel) reacts with oxygen in the cells of living things energy is released for use by the body.
