Study Reports It Is Safe to Drink Up to 25 Cups of Coffee a Day

Drinking up to 25 cups of coffee a day is safe, according to a new study—but this doesn’t mean you should drink that much.

The study was only looking at coffee’s impact on the heart. Researchers found that drinking up to 25 cups of coffee a day doesn’t contribute to artery stiffness. Artery stiffness has been linked to an increased risk of having a stroke or heart attack.

“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,” the Queen Mary University of London’s Dr. Kenneth Fung stated.

The research was funded in part of the British Heart Foundation and done at Queen Mary University of London. The study observed approximately 8,400 coffee drinkers in the UK.

“Although our study included individuals who drink up to 25 cups a day, the average intake amongst the highest coffee consumption group was five times a day,” said Fung. “We would like to study these people more closely in our future work so that we can help to advise safe limits.”

The Mayo Clinic recommends a limit of four cups of coffee, or around 44 mg of caffeine per day for adults.
