Evaluation of Green Tea for Improving Blood Lipid Profile

The objects of this study are to evaluate the effects of the "Heysong japanese green tea" on the human subjects who are dyslipidemia. In this trial, 40 healthy subjects whose ages are 18~65 years old (20 for placebo and 20 for experimental) will be included. The total experiment will be 16 weeks and the intervention period will be 12 weeks, within which, at wk 0, 2, 8, 14 and 16, serum triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) values would be measured. Urine/feces samples and anthropometric data will also be acquired. The results will be analyzed according to the methods published by the Ministry of Health and Welfare of Taiwan Food and Drug Administration.
