Effect of Green Tea Consumption on HDL-Cholesterol

Abstract

Objective: To evaluate the effect of green tea consumption on HDL-cholesterol level in hyperlipidemic patients Materials and Methods: Forty hyperlipidemic patients were selected from Ghurki Trust Teaching Hospital Lahore and divided in two groups with 20 patients in each group.Group-I was advised to take, six hourly 180 ml green tea prepared by conventional method for two months. Group-II was labeled as control, not to take green tea for 2 months. Their HDL-cholesterol was measured at day-0 and on day-60. HDL-cholesterol was measured by separating other lipoprotein fractions using chemical precipitation with divalent ions such as Mg2+, then coupling the products of a cholesterol oxidase reaction to an indicator reaction. Results: After two months, it was observed that green tea consumption raised HDL-cholesterol by 7.5 mg/dl, while control group’s HDL-cholesterol was raised 0.8 mg/dl only in this period. Conclusion: Consumption of green tea raised HDL-cholesterol significantly and can be considered as negative risk factor for development of coronary artery disease.
