Coffee is one of the most commonly consumed beverages in the worldwide and is assumed to have protective effects against metabolic syndrome. The present study was aimed at investigating the effect of coffee on body weight, serum glucose, uric acid and lipid profile levels in male albino Wistar rats feeding on high fructose diet. A post-test experimental study was conducted on a total of 30 (9-10 weeks old) male albino Wistar rats. The rats were divided into 6 groups: group I (normal control)-fed on standard chow and plain tap water only; group II (fructose control)-fed on standard chow and 20% of fructose solution; group III-VI (treatment groups)-fed on standard chow, 20% of fructose solution and treated with 71, 142, 213 and 284 mg/kg body weight/day of coffee respectively for six weeks. At the end, body weight, serum glucose, uric acid and lipid profile levels were investigated. Data was entered and cleared by epi-data software version 3.1 and analyzed by one way ANOVA followed by Tukey post hoc multiple comparison tests using SPSS V. 23.00. Statistical significance was considered at < 0.05. The results showed that body weight, fasting serum glucose and uric acid levels significantly lowered in rats treated with 213 ( = 0.047; 0.049; 0.026) and 284 ( = 0.035; 0.029; 0.010) mg/kg body weight/day of coffee compared to fructose control group. Fasting serum triglycide (TG) and low density lipoprotein (LDL-C) levels showed significant reduction in rats treated with 284 mg/kg body weight/day of coffee as compared to fructose control group ( = 0.031; 0.046) respectively. In conclusion, treating rats with coffee decreased body weight, fasting serum glucose, uric acid, TC, TG and LDL-C, and increased HDL-C in a dose dependent manner in rats feeding on high fructose diet, suggesting that coffee consumption may be helpful in ameliorating metabolic syndrome.
咖啡是全球最常饮用的饮品之一,被认为对代谢综合征具有保护作用。本研究旨在调查咖啡对食用高果糖饮食的雄性白化Wistar大鼠体重、血糖、尿酸和血脂水平的影响。对总共30只(9 - 10周龄)雄性白化Wistar大鼠进行了一项试验后实验研究。大鼠被分为6组:第一组(正常对照组)仅喂食标准饲料和普通自来水;第二组(果糖对照组)喂食标准饲料和20%的果糖溶液;第三至六组(治疗组)喂食标准饲料、20%的果糖溶液,并分别以71、142、213和284毫克/千克体重/天的咖啡进行治疗,为期六周。最后,对体重、血糖、尿酸和血脂水平进行了调查。数据由Epi - Data软件3.1版录入并清理,使用SPSS V. 23.00进行单因素方差分析,随后进行Tukey事后多重比较检验。统计学显著性设定为< 0.05。结果显示,与果糖对照组相比,以213(P = 0.047;0.049;0.026)和284(P = 0.035;0.029;0.010)毫克/千克体重/天的咖啡治疗的大鼠,其体重、空腹血糖和尿酸水平显著降低。与果糖对照组相比,以284毫克/千克体重/天的咖啡治疗的大鼠,空腹血清甘油三酯(TG)和低密度脂蛋白(LDL - C)水平分别显著降低(P = 0.031;0.046)。总之,在食用高果糖饮食的大鼠中,用咖啡治疗可使体重、空腹血糖、尿酸、总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白(LDL - C)降低,并使高密度脂蛋白(HDL - C)呈剂量依赖性增加,这表明饮用咖啡可能有助于改善代谢综合征。
