Effect of tea consumption on blood lipid profile in human

The effect of tea consumption on blood lipid profile and antioxidant status in humans was carried out at the department of Food Science and Nutrition, Aspee college of Home Science, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, on 34 subjects residing at the Sardarkrushinagar, dist. Banaskantha, Gujarat. Subjects were divided into two groups, experimental group and control group. Experimental group consist of 22 subjects and control group with 12 subjects. Experimental group consisted of volunteers whose daily intake of black tea was more than 3 cups per day whereas; the control group (placebo group) was non tea drinkers. Overnight fasting blood samples were collected and analyzed for lipid profile (Total Cholesterol, Triglycerides, LDLcholesterol and HDL-cholesterol) in tea drinkers and non tea drinkers. The result of plasma total cholesterol concentration among tea drinkers (169.28 mg %) was non significantly reduced than non tea drinkers (176.65 mg %). The reduction of plasma total cholesterol concentration among tea drinkers was –3.9per cent than non tea drinkers. The result of plasma triglycerides concentration among tea drinkers (147.56 mg %) was non significantly reduced than non tea drinkers (160.78 mg %). The reduction of plasma triglycerides concentration among tea drinkers was –8.1per cent than non tea drinkers. The result of plasma LDL-cholesterol concentration among tea drinkers (86.54 mg %) was significantly reduced than non tea drinkers (100.96 mg %). The reduction of plasma LDLcholesterol concentration among tea drinkers was –14.0 per cent than non tea drinkers. The result of plasma HDLcholesterol concentration among tea drinkers (82.91 mg %) was significantly increased than non tea drinkers (75.68 mg %). Increased of plasma HDLcholesterol concentration among tea drinkers was –9.3per cent than non tea drinkers.
