ABSTRACT
［Objective］Currently, a dietary survey is conducted to understand the dietary intake such as the nutritional values of daily diet. However, the calculation of nutritional values from diet is often targeted at the diet of people after World War II, and the diet of people before that time are rarely targeted. Therefore, few studies have tried to calculate the nutritional values of diet before the early Showa period from historical records such as ancient document. In this study, we tried to calculate the nutritional values from description of the diet in［Nenchu gyoji oiwai kondate narabini sanpo nado okazari］; historical records of Hirosaki domain in Edo period. Based on the result, we examined whether historical records in Edo period can be used to estimate the nutritional values of diet.
［Methods］We selected zoni, tazukuri, kazunoko and uchimame from the［Nenchu gyoji oiwai kondate narabini sanpo nado okazari］, and estimated the nutritional values of these dishes by using the Standard Table of Food Composition in Japan 2015 (Seventh Revised Version).
［Results］The nutritional values of the diet can be estimated from the［Nenchu gyoji oiwai kondate narabini sanpo nado okazari］. The energy of zoni, tazukuri, kazunoko and uchimame was estimated to be 446kcal, 81kcal, 49kcal, and 46kcal, respectively.
［Conclusions］The nutritional values of each dish estimated in this study is considered to be equivalent to the result of nutritional values by the photograph method, which is one of the current dietary survey. Therefore, this study suggested that the nutritional values of diet from historical records such as in Edo period can be estimated by utilizing the knowledge of current dietary surveys.
