Drinking dark tea every day may help to mitigate type 2 diabetes risk and progression in adults through better blood sugar control, suggests new research at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Hamburg (2-6 Oct).

The study, by researchers from the University of Adelaide in Australia and Southeast University in China, found that compared with never tea drinkers, daily consumers of dark tea had 53% lower risk for prediabetes and 47% reduced risk for type 2 diabetes, even after taking into account established risk factors known to drive the risk for diabetes, including age, gender, ethnicity, body mass index (BMI), average arterial blood pressure, fasting plasma glucose, cholesterol, alcohol intake, smoking status, family history of diabetes and regular exercise.

“The substantial health benefits of tea, including a reduced risk of cardiovascular disease and type 2 diabetes, have been reported in several studies over recent years, but the mechanisms underlying these benefits have been unclear”, notes the study’s co-lead author Associate Professor Tongzhi Wu from the University of Adelaide and The Hospital Research Foundation Group Mid-Career Fellow.
