Researchers at Southern Medical University in China have found that study participants who drank 1.5 to 3.5 cups of coffee per day, even with a teaspoon of sugar, were up to 30% less likely to die during the study period than those who didn’t drink coffee. News24 reports that participants who had about three cups of coffee per day had the lowest risk of dying compared with non-coffee drinkers with the findings consistent even after the researchers adjusted for sociodemographic, lifestyle, and clinical factors. Dr Christina Wee however cautioned that this was an observational study, so the findings cannot conclusively prove that coffee itself lowers the risk of dying.
