Socioeconomics and Psychological Studies on The Future of The Japanese Dietary Life

这项研究的一个主要目的是用社会经济学和心理学的方法来考察日本人饮食生活的未来。从20世纪50年代中期至70年代末，日本经济的显著增长极大地改变了日本人的饮食模式，这种变化被称为饮食模式的现代化或西方化。但是，在可持续增长的今天，我们的饮食生活达到了饱和阶段，就蛋白质、脂肪、碳水化合物(P.F.C.卡路里的组成)而言，日本人实现了理想的饮食生活。到目前为止，西方国家一直在评估这样的饮食习惯。目前，我们的饮食生活已经达到饱和或成熟阶段。通过对日本人饮食生活未来的各种分析，下一步的两点变得明确：(1)主成分分析结果提取了两个呈现增减因素和持平趋势的因素。(2)畜产品、油脂等消费增长已达到饱和阶段。(3)通过对食物消费的需求分析、趋势分析和增减率的计算，我们的饮食生活在数量上明显处于饱和阶段。(4)因子分析提取了三个因子。因素1是安全和健康因素，因素2是外化因素，因素3是进餐满足因素。我们的饮食生活也是从现在开始研究目前趋势的综合结果，从量的方面的变化已经基本完成，另一方面，从质的方面预计会继续变化。

A major objective of this study is to examine the future of the Japanese dietary life by means of socioeconomics and psychological method. The remarkable growth of the Japanese economy which began in the mid-1950s and lasted until the late-1970s changed greatly the dietary pattern of the Japanese.The change in Japan was called the modernization or the westernization of the dietary pattern. But, our dietary life reach a stage of saturation in the present day of the sustainable growth, and an ideal dietary life for Japanese in terms of protein, fat, carbohydrate (composition of P.F.C. calorie) achieved. Western countries have evaluated such eating habits continuously so far. At present, it is considered that our dietary life has reachedthe saturation or the maturity stage.As a result of the various analyses on the future of the Japanese dietary life, two points of the next became clear, (1)Two factors which showed an increase and decrease element and a flat tendency were extracted as a result of the principal component analysis. (2)Consumption such as the livestock products and oils increasing so far reached a stage of saturation. (3)As for our dietary life, it became obvious that it was here in a stage of saturation quantitatively as a result of calculating the demand analysis of the food consumption and a trend analysis and an increase and decrease rate. (4)Three factors were extracted as a result of the factor analysis. Factor1 is a safety and health factor, factor2 is a externalizing factor, factor3 is a meal fulfillment factor. Our dietary life last as a synthetic result of the research on the present trend from now on, too, and a change from the quantitative side is almost finished, and it is expected on the other hand, to keep changing from the qualitative side.
