In the year A new study presented at the 2022 annual meeting of the European Association for the Study of Diabetes (EASD) analyzed data from nearly 20 studies involving one million adults and found a link between drinking tea and a reduced risk of type 2 diabetes. But it all depends on how much tea you drink.

Many over the years Research is accumulated Referring to that The potential health benefits of tea, from improving cardiovascular health to reducing the risk of cancer. This new study was designed to investigate and clarify a topic that is particularly uncertain – the relationship between tea consumption and the risk of type 2 diabetes.

A two-part review of previous research was conducted. The first phase was a 12-year study looking at data from more than 5,000 adults. About half of the group reported drinking tea, but at the end of the follow-up period there were similar rates of type 2 diabetes in both tea drinkers and non-tea drinkers.

Therefore, the next part of the study was designed to investigate whether there is a dose-response relationship between tea consumption and diabetes. Looking at 19 studies that included detailed information on the frequency of tea drinking, the researchers found that the more tea a person drank on a regular basis, the lower their risk of developing type 2 diabetes.

People who drank one to three cups of tea a day were 4% less likely to develop diabetes compared to non-drinkers, but those who drank at least four cups a day had a 17% lower risk of developing diabetes.

According to study leader Xiaying Li, the reduction in diabetes risk was observed even after accounting for gender, geographic location and type of tea consumed. Lee suggests that something in the tea may put a person at risk for diabetes.

“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,” Lee speculated. This explains why we did not find an association between tea consumption and type 2 diabetes in the cohort study because we did not observe high tea consumption.

Of course, these findings have several caveats. The study has not yet been peer-reviewed or published in a journal, and is based on self-reported dietary questionnaires, which cannot track long-term food habits in detail. Also, the data does not provide any insight into the ways in which people consume tea. For example, does drinking tea with or without milk affect diabetes?

to speak The guard, the milk in tea can enhance the health benefits of tea. however, A 2002 study found Milk may reduce the insulin-enhancing activity of tea, which may prevent milk tea from preventing diabetes.

“While more research is needed to determine the exact dose and mechanism behind these observations, our findings suggest that tea consumption may be beneficial in reducing the risk of type 2 diabetes, but only in large amounts (at least 4 cups per day),” he said.
