Abstract

Background: This study aims at investigating the possible effects of different daily doses of green tea (GT) intake for eight weeks on certain anthropometric, metabolic, and oxidative stress biomarkers of diabetic patients.

Materials and methods: This randomized clinical trial included 63 patients with type 2 diabetes (30 males and 33 females). After a two-week run-in period without green tea, they were randomly assigned into one of the three groups, with a different daily intake of green tea; four cups of green tea per day (n = 24), two cups of green tea per day (n = 25), and the control group (n = 14) with no green tea intake for two months. At baseline and after the intervention, blood tests, dietary, and anthropometric variables were assessed. The patients were instructed to maintain their usual dietary intake and normal physical activity.

Results: Consumption of four cups of GT per day caused a significant decrease in body weight (73.2 to 71.9) (P < 0.001), body mass index (27.4 to 26.9) (P < 0.001), waist circumference (95.8 to 91.5) (P < 0.001), and systolic blood pressure (126.2 to 118.6) (P < 0.05) in this group. No significant change was seen in the other groups and between group comparisons. The metabolic and oxidative stress parameters did not show any significant differences within and between groups.

Conclusion: Drinking four cups of green tea led to a significant reduction in weight and systolic blood pressure.
