Drinking Tea Lower Diabetes Level: Types, Risk and Benefits

Washington [US]: Research on over 1 million human beings from 8 countries observed that mild use of black, green, or Oolong tea is related to a decreased chance of having type 2 diabetes.So, According to new research that moderate drinking of black, green, or oolong tea linked to lower level of type 2 diabetes.

Drinking Tea Lower Diabetes Level

The findings, being presented at this yr’s European Association for the Study of Diabetes (EASD) Annual Meeting in Stockholm, Sweden (19-23 Sept), advise that drinking at least four cups of tea an afternoon is related to a 17 in keeping with cent lower chance of T2D over a median duration of 10 years.

“Our effects are exciting because they endorse that human beings can do something as easy as drinking 4 cups of tea a day to potentially lessen their threat of growing kind 2 diabetes”, says lead writer Xiaying Li from Wuhan University of Science and Technology in China.

Benefits of Drinking of Tea

While it is long known that ingesting tea may be useful for fitness because of the numerous antioxidant, anti-inflammatory, and anticarcinogenic compounds tea incorporate, much less clear has been the relationship between tea consumption and the risk of T2D. So some distance, published cohort research, and meta-analyses have pronounced inconsistent findings.


To deal with this uncertainty, researchers performed a cohort look and a dose-reaction meta-analysis to better define the connection between tea intake and future T2DM threat.

First, they studied 5,199 adults (2583 men, 2616 girls) without a history of T2D (common age forty-two) from the China Health and Nutrition Survey (CHNS), who were recruited in 1997 and observed until 2009. The CHNS is a multicentre prospective look at searching at the economics, sociological issues, and health of citizens from 9 provinces.

Participants stuffed in food and drink frequency questionnaires at the outset and provided records on lifestyle elements consisting of a normal workout, smoking, and alcohol consumption. Overall, 2,379 (forty-six%) individuals suggested drinking tea, and by means of the cease of the study, 522 (10%) contributors had developed T2D.

Type 2 Diabetes Risk Factor

After adjusting for factors that might be linked with an increased danger of T2D, like age, intercourse, and bodily state of no activity, researchers determined that tea drinkers had a similar danger of growing T2D in comparison to non-drinkers.

And the effects did now not alternate notably while analyzed with the aid of age and sex, or while members who advanced diabetes at some point of the primary 3 years of follow-up have been excluded.

Evaluation of Tea Drinking

In the following step of the take a look at, the researchers did a scientific evaluation of all cohort research investigating tea drinking and the chance of T2D in adults (aged 18 or older) up to September 2021. Overall, 19 cohort research involving 1,076,311 contributors from 8 nations [1] had been protected in the dose-reaction meta-evaluation.

They explored the potential effect of various kinds of tea (inexperienced tea, oolong tea, and black tea), frequency of tea ingesting (less than 1 cup/day, 1-three cups/day, and 4 or more cups/day), intercourse (male and female), and the region of the take a look at (Europe and America, or Asia), at the threat of T2D.


Overall, the meta-evaluation found a linear association between tea ingestion and T2D chance, with every cup of tea consumed step by day decreasing the risk of growing T2D by way of around 1%.

When in comparison with adults who didn’t drink tea, people who drank 1-3 cups day by day reduced their chance of T2D by 4%, whilst people who fed on a minimum of four cups each day decreased their danger by 17%.

The associations were discovered no matter the type of tea individuals drank, whether or not they were male or lady, or in which they lived, suggesting that it may be the amount of tea taken up, rather than another issue, that performs a major position.

High Doses of Tea Drinking

“While extra research desires to be performed to determine the precise dosage and mechanisms behind those observations, our findings advise that drinking tea lower the level of diabetes and drinking tea is useful in decreasing the chance of kind 2 diabetes, however best at high doses (as a minimum of 4 cups a day)”, says Li.

She adds, “It is feasible that specific additives in tea, which include polyphenols, can also reduce blood glucose tiers, but enough quantity of those bioactive compounds may be needed to be effective.

So, It may additionally explain why we did not locate an affiliation between tea ingesting and sort 2 diabetes in our cohort study because we did no longer look at better tea consumption.”

Oolong Tea

Oolong tea is a traditional Chinese tea it really is made from an identical plant used to make inexperienced and black teas.

The difference is how the tea is processed–inexperienced tea isn’t always allowed to oxidize plenty, black tea is allowed to oxidize till it turns black, and oolong tea is partially oxidized.


Despite the critical findings, the authors notice that the look is observational and can’t prove that consuming tea reduced the chance of T2D, however, indicates that it probably makes contributions.

And the researchers point to several caveats, which include that they depended on subjective checks of the portions of tea consumed and that they cannot rule out the opportunity that residual confounding by using another way of life and physiological elements might also have affected the results.
