Nutrition labels on the back or side of packaging Nutrition labels are often displayed as a panel or grid on the back or side of packaging. For example, the image below shows the nutrition label on a loaf of white bread. This type of label includes information on energy (kJ/kcal), fat, saturates (saturated fat), carbohydrate, sugars, protein and salt. It may also provide additional information on certain nutrients, such as fibre. All nutrition information is provided per 100 grams and sometimes per portion.
