Since 2015, it has been required to declare the nutrient contents of processed foods in terms of calories, proteins, fats, carbohydrates, and salt equivalents. In principle, the declared values of nutrients are based on analytical values obtained using methods authorized by the Food Labeling Standards. However, values calculated by reference to reasonable sources such as the Standard Tables of Food Composition in Japan (SFCTJ) are also acceptable. In order to allow consumers to compare nutrition labeling and select suitable foods, it is desirable for these calculated values to approximate the analytical values. SFCTJ 2020 (Eighth revised edition) changes the energy calculation method from that in SFCTJ 2015 (Seventh revised edition) and presents the amounts of some nutrients in several ways. Therefore, this paper compares the analytical methods for nutrient declarations and SFCTJ 2020 and considers the most appropriate method for referring to SFCTJ 2020 for nutrient declarations.
