- Description:
- Change of Japanese dietary lives, especialy multifacialization, is one of the most interesting phenomena in the Japanese society. It is closely related to various social tendencies; contraction of the family size, shortage of the labor force, increase of aged people, rising up of the income levels, increase of the number of married women with occupation and of unmarried women, progress of the food technology, increase of the number of highly educated people, etc. The present study is a trial of model building for the analysis of change of Japanese dietary lives, based upon system dynamics. Simulation was carried out up to the year 2005, for total dietary expense, expense for processed foods, expense for dining-out, etc. According to the simulation results, the fraction of expense for the processed foods and dining-out in total life expenditure increases more rapidly compared with that of total dietary expense, and, in addition, it depends upon families’ income level. That means that social work division of preparing foods and meals, which has, so far, been housewives’ work, is now rapidly advancing in Japan, and that the tendency toward seeking pleasures in foods and meals is getting stronger. These results suggests, with other changing social tendencies, bipolarization of Japanese dietary lives, e.g. professional cooking - domestic cooking; natural type- sophisticated type; tradition-oriented type- globalization type; isolate type- family type; practice type- pleasure-oriented type.
