Let’s unpack what happens when our body receives more energy than it needs, how this can lead to weight gain and what you can do to decrease your risk of cancer.

Where do we find sugar?

In terms of health risks, we need to be concerned about ‘added sugar’. That is, sugar that has been added to food or drink.

Natural sugars in foods

  • Fruit and milk products
  • High in nutrients – vitamins, minerals, fibre or calcium.
  • We should eat these foods every day.

Sugar added to food

  • Processed foods
  • These foods are unhealthy and high in energy (kJ).
  • They don't have other nutrients we need such as fibre, vitamins and minerals.
  • We should limit these foods.
