Black Tea Lowers Type 2 Diabetes Risk

Thursday, 08 November 2012 12:05 PM

In countries where people commonly drink black tea, the rates of Type 2 diabetes are lower, according to a new study. The new research supports earlier studies that suggests that drinking black tea regularly reduces the risk of diabetes.
Researchers Ariel Beresniak of Data Mining International, in Geneva, Switzerland, and colleagues looked at black tea consumption in 50 countries on every continent in 2009 and compared that to rates of diabetes and cancer, as well as respiratory, infectious, and cardiovascular diseases in those nations.
Ireland had the highest level of black tea consumption (more than 4.4 pounds a year per person), closely followed by the United Kingdom and Turkey. Nations with the lowest levels of black tea consumption were South Korea, Brazil, China, Morocco, and Mexico.
Statistical analyses showed that diabetes rates were low in countries with high levels of black tea consumption. There was no association between black tea consumption and any of the other health conditions included in the study, according to a journal news release.
"These original study results are consistent with previous biological, physiological and ecological studies conducted on the potential of [black tea] on diabetes and obesity," and provide "valuable additional scientific information at the global level," the researchers wrote.
Black tea contains a number of complex flavonoids that have been linked with several potential health benefits, the researchers noted. The brewing process releases these flavonoids.
The number of people with Type 2 diabetes will rise from 285 million in 2010 to 438 million in 2020, the International Diabetes Federation estimates.
Even though the study found an association between consumption of black tea and the rates of Type 2 diabetes, it did not prove a cause-and-effect relationship.
