A relationship between the amount of dietary fat, the concentration of serum lipids and the development of coronary heart disease has been one of the most important medical problems in the recent years. Accumulated data indicate that striking differences exist among different populations in the incidence and severity of coronary heart disease and these differences tend to correlate with dietary factors rather than with racial or other factors. Extensive studies on healthy peoples in various parts of the world lead to the conclusion that the incidence of coronary heart disease is directly to related the average level of serum cholesterol and this cholesterol level is directly related to the percentage of calories provided by fats in the diet, particularly common saturated fats of meats and dairy products. Such a study has never been carried out in Korea and studies in other countries of the Far· East have indicated that their diets are extremely low in the fat content and their serum cholesterol and frequency of the coronary heart disease are also remarkably low. In an attempt to correlate the dietary fat intake, blood lipid level and the Incidence of coronary heart disease in Korean people, the following population groups are selected. 319 farmers, 100 Taegu City people, 50 upper class people, 129 Buddhist Monks, and 90 Korean soldiers attached to the United States Army who have been fed American diet for from 1 to 18 months and 60 American soldiers and officers. On all of those people an analysis of dietary constituents, complete blood lipid analysis including total and free cholesterol, cholesterol ester, total esterified fatty acid . lipid phosphorus, neutral fat. C/P ratio and cholesterol ester/total cholesterol ratio and 12 leads electrocardiogram for evidences of the coronary heart disease were performed and the data thus obtained were analyzed and correlated. The most striking difference in diets of various groups is the fat content. The fat intake of Buddhist Monks and farmers is significantly lower than any other groups and their serum lipid level and the incidence of abnormal electrocardiogram are also lowest in the whole groups. Among Koreans upper class people of Taegu city have the highest fat intake and also the highest serum lipid level and the incidence of abnormal electrocardiogram. The dietary fat intake of Korean is significantly lower than that of American and the serum lipid level and the incidence of coronary heart disease are also significantly lower than American. The results of current study indicate that there is direct correlation between the dietary fat intake, the serum lipid level and the incidence of coronary heart disease and it seems to be reasonable to conclude that among many factors which may affect the remarkably low incidence of the coronary heart disease in Koreans the low dietary fat intake is the most important factor.
