Is too much coffee bad for your arteries?

June 4, 2019

For years we have been told that drinking too much coffee could be bad for your heart. The thory was that if you drank too much coffee your arteries would stiffen, which could increase the workload on the heart. That extra workload would increase a person's chances of having a heart attack or stroke. According to a recent study from Queen Mary's William Harvey Research Institute, those original findings have been debunked. The new research included a much larger sample size than the original studies. The Queen Mary study compared people who drink less than one cup of coffee per day with those who drink more than three cups per day. The results found no difference in the arteries of the study participants including some participants who drank upwards of 25 cups of coffee per day. Professor Metin Avkiran, Associate Medical Director at the British Heart Foundation, said “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. This research will hopefully put some of the media reports in perspective, as it rules out one of the potential detrimental effects of coffee on our arteries.”
