Japan has experienced great socioeconomic development together with industrialization, urbanization and motorization since 1945. This has resulted in dramatic changes in both the frequency of disease and the spectrum of diseases, as well as in a rapid increase in the elderly population. Changes in eating patterns during the past 40 to 50 years seem to be a major factor in this evolution. Departure from the traditional Japanese diet, which was very high in salt and low in fat and protein (currently the diet is 25% calories from fat, 60% from carbohydrate and 15% from protein and 12 gm salt/day), has been associated with a reduced incidence of stroke, but not with an increase in coronary heart disease mortality. Therefore, the current Japanese diet may be an optimal eating pattern for maintaining health. However, since the exposure to increased fat calories is recent, future trends must be carefully monitored.
自1945年以来，日本经历了巨大的社会经济发展，同时伴随着工业化、城市化和机动化。这导致了疾病发生率和疾病谱的显著变化，以及老年人口的迅速增加。过去40到50年饮食模式的变化似乎是这一演变的主要因素。摒弃传统的日本饮食（其盐含量很高，脂肪和蛋白质含量很低，目前的饮食中脂肪提供25%的热量，碳水化合物提供60%，蛋白质提供15%，每天盐摄入量为12克），与中风发病率降低有关，但与冠心病死亡率增加无关。因此，目前的日本饮食可能是维持健康的最佳饮食模式。然而，由于增加脂肪热量的摄入是最近才出现的情况，必须密切监测未来的趋势。
