SYDNEY, Dec. 16 (UPI) -- Drinking coffee -- even decaf -- and tea regularly may help reduce the risk of type 2 diabetes, Australian researchers say.
Rachel Huxley of The George Institute for International Health at the University of Sydney and colleagues identified 18 studies involving 457,922 participants and assessing the association between coffee consumption and diabetes risk published between 1966-2009.
When the authors combined and analyzed the data, they found each additional cup of coffee consumed in a day was associated with a 7 percent reduction in the excess risk of diabetes. Individuals who drank three to four cups per day had an approximately 25 percent lower risk than those who drank between zero and two cups per day, the study said.
In the studies that assessed decaffeinated coffee consumption, those who drank more than three to four cups per day had about a one-third lower risk of diabetes than those who drank none.
Those who drank more than three to four cups of tea had a one-fifth lower risk than those who drank no tea.
The findings are published in the Archives of Internal Medicine.
