Outline of Final Research Achievements

In this study, validity of the estimated dietary amino acid values in the amino acid composition table (AACT) 2015 was examined by comparing differences between the estimated and analytical values, for 14 consecutive days’ meals provided in an elder care facility. There were no major differences between the analytical and estimated values over the 14 days; however, noticeable daily differences sometimes emerged. These results indicate that the AACT 2015 may contain errors, but allows the estimation of habitual amino acid intake. In the near future, protein calculated as the sum of amino acid residues (PROTCAA) will become the international standard. It will be necessary to convert protein content calculated as reference nitrogen multiplied by a nitrogen to protein conversion factor (PROTRN) values to fefer to past reports and data; we have determined a correction factor (0.92) for this conversion.
