Abstract

The revised version of the Standard Tables of Food Composition in Japan (STFCJ 2020) was published in 2020. The aim of the present paper is to discuss issues concerning calculation of protein and fat using food components listed in STFCJ 2020. In SFTCJ 2020, in addition to conventional values of protein content calculated as reference nitrogen multiplied by protein conversion factor <XN> (PROTRN) and gravimetrically determined fat (FAT), values of protein were expressed as the sum of amino acid residues <PROTCAA> and values of lipids as triacylglycerol equivalents of fatty acids <FATNLEA>. Protein and fat contents were significantly decreased when the preferred analytical methods of the United Nations Food and Agriculture Organization (PROTRN and FATNLEA) were applied instead of the conventional values. Therefore, it is important to compare calculated protein and fat using PROCTAA and FATLEA to calculations from previous studies of protein and fat.
