Drinking more than three cups of tea a day reduces the risk of diabetes according to an analysis of studies published in the December 14/28 issue of Archives of Internal Medicine.
The researchers from the University of Sydney, Australia, identified 7 studies involving 286,701 participants and assessing the association between tea consumption and diabetes risk published between 1966 and 2009.
Commenting on the research study, Dr Carrie Ruxton, independent nutritionist and scientific advisor to the Tea Advisory Panel notes (TAP): “When the authors combined and analyzed the data, they found that individuals who drank three to four cups per day had an approximately 25 per cent lower risk than those who drank between zero and two cups per day. In addition, those who drank more than three to four cups of tea had a one-fifth lower risk than those who drank no tea.”
“This analysis of studies is not the first to show that tea might reduce the risk of diabetes. A meta-analysis of 9 studies published earlier this year also indicated that consumption of four or more cups of tea each day could reduce the risk of diabetes. This protective effect of tea may be due to the variety of compounds present in tea, including antioxidants.
“These study findings could have significant implications for people at risk of diabetes. In the UK, there are currently over 2.3 million people with diabetes, more than half a million people have diabetes and don’t know it, and the incidence of the disease is increasing. If tea proves to be beneficial in helping to reduce the risk of diabetes, this is very good news for the large number of people in the UK who enjoy drinking black tea. Moreover, drinking three to four cups of tea a day or more is likely to produce health benefit, not only in relation to diabetes, but also for heart health.”
