The news about coffee just keeps getting better. In a new analysis of one of the country’s largest and longest-running studies, drinking coffee was linked to a lower risk of heart failure, stroke and coronary heart disease. Every extra cup of coffee consumed per day reduced each of these conditions by 8%, 7% and 5%, respectively, up to at least six cups per day.
The preliminary research was presented at the American Heart Association’s Scientific Sessions in Anaheim, California. It has not yet been published in a peer-reviewed medical journal, but it’s not the first research to suggest that coffee protects the heart and arteries.
Researchers from the University of Colorado medical school analyzed data from the Framingham Heart Study, which has tracked the eating patterns and cardiovascular health of more than 15,000 people since the 1940s. They were looking for previously unidentified risk factors for heart failure and stroke. They used a method known as machine learning, a form of artificial intelligence that looks for patterns in big data sets, similar to the way e-commerce websites might predict products a customer mighty like based on their previous shopping history.
