Patients Lifestyle such as habitual consumption of certain meals and beverages plays major role in the development of diabetes. There is strong positive association between overall obesity as measured by Body Mass Index (BMI), blood cholesterol, blood pressure and diabetes. Black and green tea and coffee are traditional beverages that are daily consumed by many Libyans. In this study, we studied the relationship between the average daily consumed amount of coffee, green tea, or black tea and fasting blood glucose, cholesterol, blood pressure or Body Mass Index (BMI) as an indicator for obesity in type 2 diabetic patient. Our study included 396 Libyan diabetic patients (292 females and 104 males) with mean age of 49±17 years from Tripoli center of diabetes. This study performed during a period of 2 years. We also included control patients who were coffee or tea non consumer type2 diabetics. The results of this study showed that as the amount of daily consumed coffee, green tea, and black tea increases there is a marked decrease in fasting blood glucose of type 2 diabetics. In addition, a habitual green tea consumption strongly reduces blood cholesterol, blood pressure and BMI while black tea has weaker effect. In contrast, coffee consumption significantly increases blood cholesterol, BMI and blood pressure of diabetics at higher doses.
