Up to 25 Cups of Coffee a Day Is Safe for Heart, Says New Study

Up to 25 Cups of Coffee a Day Is Safe for Heart, Says New Study

If you’re worried that drinking coffee is bad for your heart, rest assured. Consuming even large amounts of coffee won’t stiffen your arteries, says a new study.

The study, funded by the British Heart Foundation, found that drinking five cups of coffee a day, and even up to 25, was no worse for your arteries than drinking less than one cup a day.

The study was presented at the British Cardiovascular Society Annual Conference in Manchester.

Coffee won’t increase stroke or heart attack risk

Researchers from Queen Mary University of London divided 8,412 people into three groups. The first group drank less than one cup of coffee a day, the second group drank one to three cups a day, and the third group drank more than three cups a day, with some consuming up to 25 cups a day.

Even those who drank 25 cups did not experience stiffening of their blood vessels. Previous studies have suggested that coffee hardens arteries, putting you at a higher risk of stroke or heart attack.

All the study participants underwent infrared pulse wave tests and MRI scans, and the researchers accounted for factors like age, smoking status, weight, and blood pressure.

“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,” says Professor Metin Avkiran, associate medical director at the British Heart Foundation, in a statement. “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.”
