Nutrition labels should support national nutrition goals aimed at reducing health problems caused by poor diets and/or inappropriate food choices. Food labels can be part of a nutrition education strategy to inform consumers and assist them in making food choices the meet their health needs. Labels can draw attention to the qualities of food products and encourage producers to develop new products.
Nutrition labels may provide information about dietary energy (kcal or calories), protein, carbohydrates, sugars, dietary fibre, dietary fat, saturated fatty, trans fatty acids, vitamins, sodium and other minerals. The label explains the amount of the nutrient in the food product and how this compares with the daily nutritional needs of the average person.
