Effect of green tea and wheat bran on professional drivers with metabolic syndrome: A controlled clinical trial
Öz
Objective: The present study aims to investigate the effect of Green Tea (GT) and Wheat Bran (WB) on Metabolic Syndrome in male drivers.
Methods: A controlled clinical trial was conducted with two intervention groups (GT and WB) and a control group on ninety male drivers with metabolic syndrome. Random allocation was done using permuted block randomization. Before the intervention, parametric measurements (height, weight, systolic and diastolic blood pressure, and abdominal circumference) and blood tests (fasting blood sugar (FBS), triglycerides (TG), high-density lipoprotein (HDL)) were checked. The GT group consumed three cups of GT tea bags (1gr) daily, and the WB group received 3.5 grams of WB powder daily. After two months, measurements and tests were repeated.
Results: There were no significant differences in blood pressure among the groups (p>0.05). The GT group showed a decrease in weight, FBS, and TG, as well as an increase in HDL. The WB group also exhibited a decrease in FBS and TG and an increase in HDL. A significant increase was found in the HDL level in the GT group before and after the intervention (p<0.05).
Conclusion: Consumption of green tea has been effective in reducing the number of patients with metabolic syndrome, and consumption of green tea and wheat bran can positively increase HDL. Also, green tea can be effective in reducing weight, FBS, and TG in male drivers suffering from metabolic syndrome.
