Researchers at Imperial College London in a July 2017 study found that “People who drink around three cups of coffee a day may live longer than non-coffee drinkers.”
Dr Gunter added: "Due to the limitations of observational research, we are not at the stage of recommending people to drink more or less coffee. That said, our results suggest that moderate coffee drinking - up to around three cups per day - is not detrimental to your health, and that incorporating coffee into your diet could have health benefits."
