Science: Up to 25 cups of coffee a day is still safe for your heart

Study says that large amounts of caffeine won't stiffen arteries 

Now this is a scientific study I can get behind. A new study found that even large amounts of coffee won't stiffen arteries and harm your heart. So when someone says you drink too much coffee, you can tell them to eff off.

 

The study, funded in part by the British Heart Foundation, found that drinking five cups of coffee a day was no worse than drinking one cup. The study, which included 8,000 people across the United Kingdom, also found that those who drink up to 25 cups of coffee a day were no more likely to experience stiffening arteries than someone drinking one cup. 

There were three groups of people in the study: people who drink less than one cup a day, people who drink one and three cups, and those who drink more than three. Some of these people in the third group — you guessed it — claim to drink up to 25 cups a day. Color me impressed.

All participants in the study were given MRI heart scans and infrared pulse wave tests. Researchers considered factors such as age, gender, ethnicity, smoking status, weight, blood pressure, diet, and how much alcohol a person drinks when compiling data and analyzing results. 

"The main message for people to take away from this is that coffee can be enjoyed as part of a healthy lifestyle, and coffee lovers can be reassured by this result in terms of blood vessel stiffness outcomes," Kenneth Fung, who lead the data analysis at Queen Mary University of London, said in an interview.

"We're not telling people to drink 25 cups a day per se. If anything, if you drink within recommended guidelines, then we don't expect to see an increase in arterial stiffness compared with those who drink one cup or less a day," he added.

    When you're thinking of reasons to go for another refill, I'd say this is a good one. But if you get coffee jitters, you might want to rethink that approach.
