The original cross-cultural comparisons between Greenland Eskimos and Danes and between Japan and Western countries suggested that a high fish intake was associated with low mortality rates from coronary heart disease. More comprehensive cross-cultural studies, e.g. the Seven Countries Study showed that the saturated fat content of the diet is more important than the amount of fish in explaining differences in coronary heart disease mortality between countries. Cohort studies carried out in cultures with a low level of fish consumption showed that persons who eat fish once or twice a week had lower mortality rates from coronary heart disease than persons who did not eat fish. The results of the epidemiological studies carried out so far suggest that a diet low in saturated fat in combination with a low level of fish consumption may be of importance for coronary heart disease prevention.
最初对格陵兰爱斯基摩人与丹麦人以及日本与西方国家之间的跨文化比较表明，高鱼类摄入量与冠心病低死亡率相关。更全面的跨文化研究，如七国研究表明，在解释各国冠心病死亡率差异方面，饮食中的饱和脂肪含量比鱼类摄入量更为重要。在鱼类消费量低的文化背景下进行的队列研究表明，每周吃一到两次鱼的人比不吃鱼的人冠心病死亡率更低。迄今为止进行的流行病学研究结果表明，低饱和脂肪饮食与低鱼类消费量相结合可能对预防冠心病具有重要意义。
