Drink Tea to Lower Your Risk of Type 2 Diabetes
What is the problem and what is known about it so far?
Type 2 diabetes is caused by a combination of genetics and the environment. Behavioral interventions, such as increasing physical activity and dietary changes, can be effective against the development of type 2 diabetes. Some studies have suggested that drinking tea may lower the risk for diabetes, but results have been mixed.
Why did the researchers do this particular study?
The researchers sought to determine once and for all whether drinking tea is linked to a lower risk of type 2 diabetes by doing a large and far-reaching study.
Who was studied?
The study included data from over 26,039 adults living in 8 European countries.
How was the study done?
Researchers asked participants, who did not have type 2 diabetes at the start of the study, about their tea intake over the previous year. Their frequency of tea consumption was categorized as no tea, between zero and one cup, between one and four cups, or greater than four cups of tea per day. The researchers also kept track of who went on to develop type 2 diabetes.
What did the researchers find?
People who drank the most tea had a 16% lower risk for developing type 2 diabetes than non-tea drinkers, with intermediate risks along the tea-drinking spectrum.
What were the limitations of the study?
This type of study cannot determine whether tea itself lowers the risk for type 2 diabetes; it can only establish an association. Tea consumption was associated with a healthier lifestyle, and while the researchers tried to disentangle the impact of a healthy lifestyle from that of tea consumption in their calculations, it is possible that living well and not tea itself lowers the risk of diabetes. Also, the researchers failed to assess what types of tea participants consumed, so it is not possible to determine if only certain teas are beneficial.
What are the implications of the study?
Drinking tea may lower the risk for developing type 2 diabetes. The benefits of tea may be due to its polyphenol (potentially healthful chemicals) content, or by its influence on glucose digestion.
