A new study suggests that drinking at least four cups of tea a day can reduce the risk of type 2 diabetes. The research findings, a review of 19 previous such studies, which will be presented at the annual meeting of the European Association for the Study of Diabetes in Stockholm, Sweden, suggest that drinking four cups of tea a day may reduce the risk of type 2 diabetes. Diabetes 17 percent.
According to the study, moderate consumption of black, green or oolong tea is associated with a lower risk of developing type 2 diabetes. The study was conducted involving more than 1 million participants from eight different countries.
“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 developing type 2 diabetes,” said Xiaoying Li of Wuhan University of Science and Technology. Technology in China, lead author of the study.
Adults who drank one to three cups of tea per day had a 4 percent lower risk of type 2 diabetes than nondrinkers, while those who drank at least four cups per day had a 17 percent lower risk of developing the disease.
The researchers found that the odds of type 2 diabetes for tea drinkers and non-drinkers were comparable after controlling for variables including age, gender and physical inactivity known to be associated with the risk of developing type 2 diabetes.
Regardless of the type of tea the participants drank, whether they identified as male or female, or where they lived, the associations were still there, suggesting that the amount of tea may be more significant than any other element in explaining the association. Lee added that drinking tea may help reduce the risk of type 2 diabetes, but only in large doses.
Oolong tea, a classic Chinese brew, is also made from the same plant that yields green tea and black tea. Oolong tea is partially oxidized while black tea is allowed to fully oxidize, this difference is due to the processing process. Green tea is not allowed to oxidize significantly.
