Worried about your latte habit? Don’t be. Downing up to 25 coffees each day is no worse for your ticker than drinking less than one, a new study funded by the British Heart Foundation has found.
Previous studies suggested that consuming too much caffeine can cause arteries to stiffen, increasing the possibility of a heart attack or stroke, but scientists at Queen Mary University of London have all but disconfirmed those claims with fresh data spanning more than 8,000 people across the UK.
Participants were split into three groups: people who drink less than one cup of coffee per day, those who sip between one and three, and a third group who down more than three.
While the average intake for the latter group was five daily cups of joe, participants who admitted to downing a mammoth 25 cups per day were no more likely to have stiffened arteries than people who barely touch the stuff, researchers found.
“Despite the huge popularity of coffee worldwide, different reports could put people off from enjoying it,” Dr Kenneth Fung from the university told The Telegraph. “Whilst we can’t prove a causal link in this study, our research indicates coffee isn’t as bad for the arteries as previous studies would suggest.
“Although our study included individuals who drink up to 25 cups a day, the average intake amongst the highest coffee consumption group was five cups a day,” he continued. “We would like to study these people more closely in our future work so that we can help to advise safe limits.”
While sweats and jitters were, unfortunately, not measured, the study “rules out one of the potential detrimental effects of coffee on our arteries,” said Professor Metin Avkiran, associate medical director for the BHF. “Understanding the impact that coffee has on our heart and circulatory system is something that researchers and the media have had brewing for some time,” he quipped. “There are several conflicting studies saying different things about coffee, and it can be difficult to filter what we should believe and what we shouldn’t.”
