Researchers from Fudan University, China and Vanderbilt University in the United States have warned that the consumption of green tea could lead to an increased risk of Type 2 Diabetes in Chinese adults.
According to the Xinhua News Agency, a total of 119,373 participants from the Shanghai Women’s Health Study and Shanghai Men’s Health Study were included in the study.
The two study populations were initiated in 1996 and the data gathered from the studies were used to investigate genetic and other biomarkers, as well as lifestyle risk factors for cancers and other chronic diseases.
None of the study participants had diabetes when they were enrolled, as details of tea drinking, including types and amounts, were collected in the survey.
The researchers reported that both female and male participants in the study have an increased risk of type 2 diabetes if they drink more green tea.
They observed in their finding, which was reported in the International Journal of Epidemiology that positive and dose-response association between green tea intake and risk of type 2 diabetes did not vary by obesity or smoking.
The study authors called for further studies on the mechanisms underlying the association, suggesting that pesticide residue in tea leaves could play a possible role.
Green tea is a popular beverage consumed worldwide, which has gained popularity as a health drink. Researchers have, however, had inconsistent findings on the association between green tea drinking and risk of type 2 diabetes.
A Japanese study published in 2016 in the Annals of Internal Medicine noted that habitual green tea drinkers, who drank at least six cups per day, had a 33 per cent lower risk for Type 2 Diabetes than those who drank one cup or less per week.
Another study in the Peoples Republic of Korea published in 2007 in the journal, BioFactors, said people with diabetes should drink less green tea as animal studies showed that high green tea intake may increase blood sugar levels in diabetic rats.
