The study presented at the annual meeting of the European Association for the Study of Diabetes (EASD)
Over the past years, it has accumulatedMany studies have cited the potential health benefits of tea, from improving cardiovascular health to reducing the risk of cancer. Now scientists have tried to clarify the relationship between tea drinking and the risk of developing type 2 diabetes.
Biologists conducted a two-part review earlierexisting studies. During the first stage, scientists conducted a cohort study. It used data from more than 5,000 adults who were followed for 12 years. About half of the patients reported drinking tea. But, by the end of the observation period, the incidence of type ll diabetes was the same in both those who drink tea and those who do not.
Therefore, during the second stage of the studyExperts tested whether the dose-response aspect influences tea consumption and the development of diabetes. After examining data from 19 studies, experts found that the risk of type 2 diabetes decreases depending on how much tea a person drinks regularly.
People who drank one to three cups of tea a day were 4% less likely to develop diabetes. Those who drank at least four cups of tea a day had a 17% lower risk of developing the disease.
Lead author of the study, Xiaying Li, said thatthe reduced risk of diabetes was observed even after controlling for gender, geographic location and the type of tea consumed. Lee said this suggests something in the drink affects the body's metabolism.
