That cup of morning tea can provide more energy than just a jolt to start the day. After reviewing recent studies, researchers concluded that people who drink four cups of either black, green, or oolong tea may have a lower risk of developing type 2 diabetes, heart disease, or stroke after a period of time.
Benefits of drinking tea during a study
Researchers in China described their discovery by citing 19 separate studies involving tea drinkers, Eureka Alert, an online promotional news service, reported.
“The results of our findings are exciting 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 disorder diabetes,” said a researcher at Wuhan University. Jiing Li said. Science and technology. “A press release posted on Eureka Alert.
The studies examined the tea drinking habits of more than one million adults in eight different countries.
The review – titled, “Tea consumption and risk of type 2 diabetes: a cohort study and updated systematic review and dose-response meta-analysis” – was presented on 21 September at the annual meeting of the European Association for the Study of Diabetes. , reported the EASD website.
What researchers found by drinking tea daily
While researchers found that drinking four cups of tea daily can reduce the risk of diabetes, heart disease and stroke by 17% over a decade, drinking fewer cups also apparently has health benefits.
People who drink one to three cups of tea daily have a 4% lower risk of developing diabetes.
According to the Centers for Disease Control and Prevention (CDC), heart disease is the leading cause of death in the United States by 2020.
Stroke and diabetes deaths were ranked fifth and eighth, respectively.
Detected by other studies
Other studies have also shown that people who drink several cups of black tea per day have a lower risk of death, according to the National Institutes of Health (NIH).
A study published in August 2022 found that among 498,000 people surveyed in the United Kingdom, those who drank at least two cups of black tea every day had a 9% to 13% risk of death, compared to those who didn’t. Didn’t. who did not do so. Drink any kind of tea, the NIH reports.
The August study also found that people who drank several cups of tea each day had a lower risk of heart disease and stroke than those who didn’t.
Conclusion for those who are already drinking tea
The findings are “very reassuring for people who are already drinking tea,” said Dr. National Cancer Institute staff scientist Maki Inou-choi told NBC News again. What’s more, an August study found that drinking excessive amounts of tea — more than 10 cups per day — did not come with additional health risks.
Inou-Choi said that neither tea has milk or sugar added to it – although the survey participants generally did not add large amounts of sugar to their tea.
There is a lot of sugar in the tea shop,” she told the same outlet. “We should still follow dietary rules to avoid using too much sugar and too much saturated cane fat.
The health benefits of consuming tea come from the polyphenols
Inou-Choi explained in a press release posted on Eureka Alert that the health benefits of consuming tea come from polyphenols, compounds that occur naturally in tea and are believed to provide antioxidant effects. Reduce swelling.
Other studies have suggested that tea consumption lowers the risk of certain cancers, reports the National Cancer Institute. However, the organization states that the evidence regarding the potential benefits of tea consumption in relation to cancer is “currently inconclusive.”
New findings related to other tea drinking and diabetes, heart disease
Others are cautioning about new findings related to tea drinking and a lower risk of diabetes, heart disease and stroke.
The words ‘suggestion’ and ‘potential’ are important here in the new study”, said Dr. Kevin McConway, Emeritus Professor of Applied Statistics at The Open University, a British public research university, in a separate statement, as reported by Medscape.
Drinking tea will be useful for treating or reducing diabetes only if the risk is reduced by drinking tea – that is, if you drink tea then the risk is reduced. And if you don’t — and this study isn’t the only one that can show whether or not it does,” Conway said.
