Drinking a lot of tea — at least four cups a day — reduces the risk of type 2 diabetes DiabetesResearch found.

The Chinese scientists behind the discovery found that drinking four or more cups of tea every day could reduce the risk by 17% over 10 years. “Our results are interesting because they suggest that people can do something as simple as drinking four cups of tea a day to reduce their risk of type 2 diabetes,” said Xiaying Li from Wuhan University of Science and Technology.

According to Lee, if people put milk in tea, the protection may be greater. Although she and her seven colleagues did not examine the effects of milk in tea as part of their work, previous studies have shown that dairy products can also have anti-diabetic effects.

“I think the milk tea will make the effect on diabetes even stronger. That is, tea with milk will be more effective,” Lee said.

She will present the findings at the annual meeting of the European Association for the Study of Diabetes in Stockholm, Sweden.

The researchers conducted a meta-analysis of 19 studies on tea drinking and diabetes in eight countries in the Americas, Asia or Europe, including one in the United Kingdom, involving nearly 1.1 million adults. They found a “significant linear association” between drinking black, green or oolong tea – a traditional Chinese tea – and a reduced risk of diabetes.

People who drank one, two or three cups of tea a day had a 4% lower risk compared to those who didn’t – but those who drank four or more cups a day had a 17% lower risk. The results were consistent across both sexes.

When asked why tea might prevent diabetes, he said, “Certain compounds in tea, such as polyphenols, may lower blood glucose levels, but sufficient amounts of these bioactive compounds may be required to be effective.”

Around 4 million Britons have diabetes. 90% of them have type 2, which is associated with an unhealthy lifestyle, especially being overweight. Others have type 1 autoimmune disease, which is not related to lifestyle and is usually diagnosed in childhood. Although the findings were not published in a medical journal, they were peer-reviewed by Stockholm conference organizers.

Lee said the findings are observational and do not prove that drinking tea lowers the risk of type 2 diabetes, but they believe it may contribute.
