Drinking black, green, or oolong tea may have more benefits than just a small energy boost — a small amount may reduce the risk of type 2 diabetes, new research has found.

Drinking at least four cups of these teas a day can reduce the risk of developing type 2 diabetes by 17 percent over an average of 10 years, according to a study published Saturday. The study, which has not yet been published in a scientific journal, will be presented this week at the annual meeting of the European Association for the Study of Diabetes in Stockholm.

The link between tea consumption and the risk of type 2 diabetes has been studied before, but the results are inconsistent, said Xiang Li, a graduate student and postdoctoral fellow at China’s Wuhan University of Science and Technology.

“Our study shows that the relationship between tea consumption and[type 2 diabetes]depends on the amount of tea. Just enough tea consumption can show clinical effects,” Lee said in an email. “Based on our findings, I recommend that the public drink more tea in their daily lives.” .

The authors of the abstract first studied 5,199 adults with no history of type 2 diabetes. Chinese Health and Nutrition Research (CHNS) CHNS is a prospective study examining the economics, sociological factors, and health of residents from nine Chinese provinces. They were recruited in 1997 and followed until 2009. At the beginning of the study, participants provided information about lifestyle factors such as food and drink habits, physical activity, smoking and alcohol consumption.

Early on, researchers found that tea drinkers and non-tea drinkers had the same risk of developing type 2 diabetes.

But when researchers decided to conduct a systematic review of 19 cohort studies involving more than 1 million adults from eight countries to examine whether consumption among tea drinkers made a difference, the results were mixed. Tea participants drink daily, the risk of type 2 diabetes is reduced. (The measures taken in these studies were whether participants drank less than one cup of tea per day, one to three cups per day, or four or more.)

The authors of their study did not prove that drinking tea reduces the risk of type 2 diabetes, but suggested that drinking tea may contribute. Based on the participants’ assessment of their tea consumption, they also pointed out that unmeasured lifestyle and physiological factors could affect the results.

The authors, who were not involved in the study, acknowledged the limitations of the current research.

Navid Sattar, a professor of metabolic medicine at the University of Glasgow, said: “People who drink a lot of tea may be less likely to drink more harmful sugary drinks or similar drinks, or because they have other health behaviors that may increase the risk of type 2 diabetes.”

“The findings should be taken with a very large pinch of salt (or a cup of tea),” Kevin McConway, a professor of applied statistics at the Open University in the UK, said in a statement. “The problem with meta-analysis findings is that the devil is always in the details, and we don’t have the details. Which studies are included? What was their quality? From which country were the people studied?

More research is needed to determine how green, black or oolong tea — and how much you drink it — affects type 2 diabetes, he said. News release.

“Special substances in tea, such as polyphenols, reduce blood glucose concentration by inhibiting the activity of α-glucosidase and/or inhibiting the activity of other enzymes, but a sufficient amount of bioactive substances is required to be effective,” he said.

Polyphenols are substances found in many plants and give some flowers, fruits and vegetables their color National Cancer Institute. Polyphenols have antioxidant properties that help prevent or delay cell damage in the body. Bioactive substances It is the nutrients or non-nutrients in foods that affect how the body works.

The take-home message is that lifestyle choices are important for controlling the risk of type 2 diabetes, Duane Mellor, a registered dietitian and senior teaching fellow at Aston University in Birmingham, UK, said in a statement. Mellor was not involved in the study.
