Food nutrition labels

  • Food nutrition labels tell us vital information about the ingredients our food contains so we can make a choice about whether or not we should eat it.
  • Labels normally tell us the number of calories, sugars, fats, saturated fats and salts.
  • If the food label mentions calories, it normally states how many calories are per serving, portion, or 100g of the food, not the whole product.
