食用茶籽油对高甘油三酯血症患者血脂和体重的影响

Effects of teaseed oil on triglyceride and weight in hypertriglyceridemic subjects

目的观察茶籽油对高甘油三酯血症患者血脂和体重的影响。方法采用自身对照研究，给予25名高甘油三酯血症患者每目摄入茶籽油25～30g，持续服用8周。在研究开始时和结束时测定身高、体质、体质指数（BMI）以及血清中油酸（OA）、总甘油三酯（TG）、总胆固醇（TC）、血糖以及丙氨酸氨基转移酶、天冬氨酸氨基转移酶并记录饮食摄入及运动情况。结果研究结束后获得21例有效数据，与基线相比，高甘油三酯血症患者血清OA含量以及从膳食中摄入的油酸、单不饱和脂肪酸摄入量显著增加（P〈0．0），多不饱和脂肪酸摄入量显著下降（P〈0．05）；体重和BMI显著下降（P〈0．05），其他指标无显著变化。结论食用茶籽油可升高血液中油酸水平，降低高甘油三酯血症患者的体重和BMI。

Objective To investigate the effects of teaseed oil on triglyceride and weight in hypertriglyceridemic subjects. Methods Twenty-five hypertriglyceridemic subjects were enrolled in the study. All subjects were required to ingest 25 - 30 g/d of the teaseed oil as cooking oil for 8 consecutive weeks. The height, body weight, BMI and the serum oleic acid （OA） , total triglyceride （TG） , total cholesterol （TC） , blood glucose, alanine aminotransferase （ ALT ） and aspartate aminotransferase （ AST ） in hypertriglyceridemic subjects were measured. The daily total energy, macronutrients intake and activity level were recorded at the beginning and ending of the study. Results Twenty-one subjects completed the study. As compared to data at the beginning, the levels of OA in serum and dietary intakes of OA, monounsaturated fatty acids significantly increased. Polyunsaturated fatty acids intake and body weight, BMI decreased significantly. Conclusion Teaseed oil could increase the serum levels of OA and reduce weight and BMI in the hypertriglyceridemic subjects with stable dietary intake and exercise.
