香港７岁儿童的血胆固醇水平（４．５９ｍｍｏｌ／Ｌ）明显高于同种族的广东省江门市同龄儿童的水平（４．１６ｍｍｏｌ／Ｌ）。用双份法收集两地各２０名儿童连续两日膳食，用化学法分析脂肪和脂肪酸含量的结果表明：江门市儿童每口摄入脂肪为３４．７ｇ，比香港儿童的摄人量（每口４７．６ｇ）低３０％左右；膳食脂肪酸模式中，多不饱和脂肪与饱和脂肪比例和亚油酸与豆蔻酸比例，江门市儿童（各为０．８１和２０．７３）均明显高于香港儿童（各为０．６９和１０．９１）。提示：在经济迅速发展、人民生活富裕后，膳食模式也会发生变化，必须尽早预防可能由此带来的营养过多造成对健康的危害，特别是对以后发生冠心病危险性的影响。
Hong Kong’s 7-year-old children’s blood cholesterol level (4.59mmol / L) was significantly higher than the same race of children in Jiangmen City, Guangdong Province level (4.16mmol / L). The results showed that the intake of fat per child in Jiangmen City was 34.7g, which was higher than the intake of Hong Kong children Mouth 47.6g) is about 30% lower; dietary fatty acid model, polyunsaturated fat and saturated fat ratio and the ratio of linoleic acid and myristic acid, Jiangmen children (each 0.81 and 20.73) were significantly higher than Hong Kong children (0.69 and 10.91 each). Tip: After the economy develops rapidly and the people’s living conditions are prosperous, the dietary patterns will also change. Therefore, we must prevent as soon as possible the health risks caused by overnutrition, especially the risk of coronary heart disease.
