饮食习惯对血脂水平的影响

Impact of diet on plasma lipid levels

目的探讨饮食习惯对血脂水平的影响,为当地人群合理营养指导提供科学依据。方法将1 500例正常饮食的人群(普食组)和800例寺院僧侣(素食组)随机分为两组:40岁以上组和40岁以下组,并测试所有人员体内总胆固醇,甘油三酯,高密度脂蛋白胆固醇与低密度脂蛋白胆固醇含量。结果对于40岁以上组和40岁以下组人群,素食组血液中TCH、TG、LDL-C含量均低于普食组,而HDL-C较普食组高,差异有统计学意义(P<0.05)。素食组血液中TCH、TG、LDL-C和HDL-C的血脂异常率较普食组低(P<0.05)。结论血脂水平与饮食习惯有关;摄取平衡饮食并建立良好的生活饮食习惯,加上坚持体育锻炼,有利于降低高脂血症和心脑血管疾病发生率。

Objective To explore the effects of dietary habit on blood fat levels , and provide scientific basis for rea- sonable nutrition guidance to local people. Methods A total of 1 500 cases of normal diet people （normal diet group） and 800 cases of monasteries of monks （vegetarian group）were randomly divided into two groups：above 40 years old group and under 40 years group. All of them were tested and measured with total cholesterol ,triglyeerides ,high-density lipoprotein cholesterol and low density lipoprotein cholesterol. Results For above 40 years group and under 40 years group,the vegetarian group in blood TCH ,TG, LDL-C levels were lower than the normal diet group,and HDL-C higher than those in the normal diet group （P〈0.05）. The dyslipidemia rates of vegetarian group in blood TCH,TG,LDL-C, HDL-C were obviously lower than those in the normal diet group （P〈0.05）. Conclusion Dietary habit plays an impor- tant role in blood fat level; Take a balanced diet and establish good eating habits,plus doing physical exercise, does good help to reducing the incidence of cardio-cerebral vascular diseases.
