摘要

背景和目的:以前从未报道过饮用不同咖啡和茶对餐后血糖和血脂代谢的影响。本研究旨在调查早餐饮用不同咖啡或茶对健康人餐后心血管代谢风险因素的影响:18名健康的年轻受试者完成了试验。经过 8 小时的隔夜空腹,志愿者在摄入水、冻干咖啡、喷雾干燥咖啡、绿茶、红茶或乌龙茶的同时,还摄入了由一个鸡蛋和 180 克油条组成的早餐。分别在 0 小时、0.5 小时、1 小时、2 小时和 3 小时抽血:结果:与红茶和乌龙茶相比,饮用绿茶 2 小时和 3 小时后甘油三酯(TG)值相对于基线水平的差异明显降低(p 结论:绿茶可降低甘油三酯(TG)的升高:摄入绿茶可降低高脂肪或高胆固醇饮食后血清 TG 和 TC 水平的升高。鉴于咖啡和茶的广泛使用以及当前对心脏代谢风险因素的关注,我们的研究结果具有深远的意义。

Effects of coffee and tea on postprandial cardiometabolic risk factors in healthy individuals: a randomized crossover trial.

Background and objectives: The effect of different coffee and tea consumption on postprandial glucose and lipid metabolism has never been reported previously. The aim of the present study was to investigate the effect of different coffee or tea consumption at breakfast on postprandial cardiometabolic risk factors in healthy individuals.

Methods and study design: Eighteen healthy young subjects completed the trial. After 8-hour overnight fast, volunteers either ingested water, freeze-dried coffee, spray-dried coffee, green tea, black tea or oolong tea together with a breakfast consisting of an egg and 180g deep-fried dough sticks. Blood was drawn at 0h, 0.5h, 1h, 2h, and 3h.

Results: The differences in triglyceride (TG) values relative to the baseline levels at 2h and 3h of green tea was significantly decreased compared with black tea and oolong tea (p<0.05). Compared with black tea, green tea and oolong tea significantly reduced postprandial total cholesterol (TC) levels (p<0.05, p<0.01), respectively. Furthermore, the serum concentrations of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were substantially decreased after oolong tea consumption compared with black tea (p<0.05, p<0.01).

Conclusions: Green tea ingestion can lower the elevation of serum TG and TC levels after high-fat or high-cholesterol diets. Our findings have far-reaching implications given the widespread use of coffee and tea and the current concern over cardiometabolic risk factors.

期刊介绍: The aims of the Asia Pacific Journal of Clinical Nutrition (APJCN) are to publish high quality clinical nutrition relevant research findings which can build the capacity of clinical nutritionists in the region and enhance the practice of human nutrition and related disciplines for health promotion and disease prevention. APJCN will publish original research reports, reviews, short communications and case reports. News, book reviews and other items will also be included. The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer-reviewed by at least two anonymous reviewers and the Editor. The Editorial Board reserves the right to refuse any material for publication and advises that authors should retain copies of submitted manuscripts and correspondence as material cannot be returned. Final acceptance or rejection rests with the Editorial Board
