None of the participants had diabetes at the time of enrollment. Details of tea types and amounts consumed were collected in a survey.
Researchers from China's Fudan University, Vanderbilt University in the US and other research institutions said after the survey, they found that both women and men participating in the study increased their risk of type 2 diabetes if they drank a lot of tea.
The researchers noted that the association between green tea intake and type 2 diabetes risk was not affected by obesity and smoking.
The team of scientists called for further research into the mechanism behind the link between tea drinking and diabetes risk, as pesticide residues in tea leaves may play a role.
Green tea is a popular beverage consumed around the world. In recent years, green tea has become popular as a health drink. But researchers have had inconsistent findings about the link between drinking green tea and the risk of type 2 diabetes.
A Japanese study published in the Annals of Internal Medicine in 2006 found that people who regularly drank six or more cups of green tea a day had a 33 percent lower risk of developing type 2 diabetes than those who drank only one cup or less per week.
A Korean study published in the journal BioFactors in 2007 said people with diabetes should drink less green tea because studies show that high amounts of green tea can increase blood sugar levels in mice./.
