Scientists looked at over 8,000 people to study the effects of coffee on the arteries.

The research involved 8,412 adults in the U.K. who had MRI heart scans and infrared pulse wave tests that measured changes to their blood volume. The participants were also asked how many cups of coffee they drank, and were placed in three groups: those who consumed less than a cup; between one to three cups; and those who knocked back more than three. The scientists excluded participants who drank more than 25 cups of coffee, as well as those who had cardiovascular disease.

Even drinking as many as 25 cups of coffee a day was not linked to stiffer arteries, according to the researchers. The work was presented at the British Cardiovascular Society Annual Conference and has therefore not yet been published in a peer-reviewed journal. Professor Metin Avkiran, associate medical Director at the British Heart Foundation, which helped to fund the study, 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.
