Most people who drink coffee appreciate the quick jolt of energy it provides. But in a new study, presented on Monday at the annual meeting of the American Society for Nutrition, scientists found that coffee may offer the much longer-term benefit of healthy ageing.
The study has not been peer-reviewed or published, but it was rigorous and included a large number of women who were followed for many years. It also adds to a large body of evidence linking coffee to longer lives and various health advantages, including lower risks of certain chronic diseases. However, all of these studies had limitations, including that they were observational and could not prove cause and effect.
