Most pre-packaged foods have a nutrition label on the packaging which includes information on energy in kilojoules (kJ) and kilocalories (kcal), usually referred to as calories. They also include information on fat, saturates (saturated fat), carbohydrate, sugars, protein and salt. Although they calculate the daily requirements of the above based on adults, the amount of each nutrient is still useful as a guide for children as children benefit from the same dietary patterns as adults, just in smaller proportions. Many food labels include a traffic light system which can be a useful guide to help families to understand whether particular foods are better as an occasional treat or are suited to daily consumption.
Food labels will also contain a list of ingredients and allergy information with the 14 recognised allergens highlighted in bold.
