根据最新的营养调查数据，对日本食物链中多不饱和脂肪酸(PUFAs)的含量进行了综述。日本人目前平均消耗约26%的能量作为脂肪，多不饱和脂肪与饱和脂肪和n-6与n-3脂肪酸的比例分别约为1.2：1和4：1。N-3多不饱和脂肪酸摄入量相对较高的重要因素不仅是鱼和贝类，还包括食用植物油，几乎完全是菜籽油和大豆油。因此，日本人的饮食习惯使得在低脂肪养生法中摄入高n-3多不饱和脂肪酸成为可能。在这方面，鱼类消费习惯的逐渐下降，特别是在年轻人中，给我们带来了沉重的负担。对健康指数的分析，包括平均寿命的增加，支持了当前日本饮食模式与西方养生方式相协调的优越性。然而，目前不能忽视的是，所有年龄段的食物摄入量都有很大差异，只有少数人摄入了推荐的膳食脂肪摄入量。
The amount of polyunsaturated fatty acids (PUFAs) in the food chain in Japan is reviewed on the basis of the newest nutrition survey data. The Japanese are currently consuming, on average, approximate to 26% of energy as fats with ratios of polyunsaturated to saturated fats and n-6 to n-3 fatty acids of approximate to 1.2:1 and 4:1, respectively. The significant contributors to this relatively high n-3 PUFA intake are not only fish and shellfish but also edible vegetable oils, almost exclusively rapeseed and soybean oils. Thus, the dietary habits of the Japanese have made possible a high n-3 PUFA intake within a low-fat regimen. In this context, the gradual decline, particularly in younger persons, in fish consumption habits weighs on our minds. Analyses of health indexes, including the increased average life span, support the superiority of the current Japanese eating pattern that harmonizes with the Western regimens. However, at present it cannot be disregarded that food intake varies considerably in all age groups, and only a limited number of people are consuming the recommended allowance for dietary fats.
