Drinking lots of coffee and tea every day — even decaf — might keep diabetes away, new research shows.
In a meta-analysis of 18 studies, drinking three to four cups of coffee per day was associated with a 25% lower risk of diabetes than drinking two cups or less per day (RR 0.76, 95% CI 0.69 to 0.82), according to Rachel Huxley, PhD, of the George Institute for International Health in Sydney, Australia, and colleagues.
There were similar results for decaf coffee and tea.
