In the present study, we investigated the effects of chronic green tea consumption on the serum lipid profiles of 92 subjects (mean age: 59.5 $pm$ 8.9, men: 41, women:51) living in a green tea cultivation village. The anthropometric and biochemical blood indices were measured, and nutritional intakes were assessed using 24-h recall method. Also, we administered a questionnaire regarding green tea consumption. The subjects were divided into three groups based on the period of green tea consumption (0, < 10 year, and $geq$ 10 year). There were no significant differences in age, anthropometric indices (Wt, Ht, BMI, Body fat, LBM), and nutritional intakes among the groups. Serum LDL-cholesterol concentration was significantly lower in the $geq$ 10 year group compared with the other groups (p < 0.05). Also, the LDL/HDL-cholesterol ratio was significantly lower in the $geq$ 10 year group compared with the other groups (p < 0.05). The frequency of subjects with a normal range of serum LDL-cholesterol concentration (< 200 mg/dl) was significantly higher in the $geq$ 10 year group compared with the other groups (p < 0.05). These results imply positive effects of chronic green tea consumption on blood lipid profiles, which requires confirmation in further studies.
