A prospective cohort study published in Diabetologia demonstrates that coffee consumption may be associated with a reduction in the risk of type 2 diabetes.
Analysis of data from a cohort of 40,011 participants showed that consumption of at least three cups of coffee or tea (regardless of the levels of caffeine content) per day reduced the risk of type 2 diabetes by approximately 42%.
These new findings are particularly important as:
Type 2 diabetes is the most common of the two main types of diabetes and accounts for between 85 and 95% of all people with diabetes.
There are currently over 2.5 million people with diabetes in the UK.
Dr Euan Paul, Executive Director of the British Coffee Association, commented, "This study adds to the overwhelming weight of evidence which demonstrates that moderate coffee consumption of four to five cups per day is safe and may even confer certain health benefits such as reducing the risk of developing Alzheimer's disease, Parkinson's disease, stroke and, as shown in this study, may even reduce the risk of type 2 diabetes.
"This study also builds on sound research in this area which has demonstrated that coffee drinking may protect against the onset of type 2 diabetes. At this stage these results do need to be supported by further research to determine the mechanism of action before any possible implications for public health and clinical practice can be considered; however, the results are encouraging."
