冠心病是危害人民健康的主要疾病之一。引起冠心病的原因是多方面的。膳食是其中的一个因素。流行病学的调查结果表明:世界上很多地区居民的膳食内动物性食品多,摄入脂肪的总量及饱和脂肪酸量较高,这些地区人群的血浆胆固醇及甘油三酯的浓度平均值都相当高,冠心病的发病率也很高。反之,在另一些地区,居民的膳食以植物性食物为主,摄入脂肪的总量低,油脂来源大部为富含不饱和脂肪酸的植物油。这些地区人群的血浆胆固醇及甘油三酯的浓度平均值都相当低,冠心病的发病率也较低。多年来国外的一些实验观察结果指出:控制膳食中的脂肪量,使脂肪热能不超过总热能的
Coronary heart disease is one of the major diseases endangering people’s health. The causes of coronary heart disease are many. Meal is one of the factors. Epidemiological survey results show that: in many parts of the world residents dietary animal food more, the total amount of fat intake and saturated fatty acid content is higher, the average plasma cholesterol and triglyceride concentrations in these populations are quite High, the incidence of coronary heart disease is also high. On the other hand, in other areas, residents’ diets are dominated by plant foods, and the total amount of fat consumed is low. Most of their fat sources are vegetable oils rich in unsaturated fatty acids. The average plasma cholesterol and triglyceride concentrations in these populations are quite low, and the incidence of coronary heart disease is also low. Over the years a number of experimental observations abroad that: control the amount of fat in the diet so fat heat does not exceed the total heat
