No, you probably shouldn’t do that.
But while new research partly funded by the British Heart Foundation doesn’t suggest you should be chugging quite that much caffeine daily, it has also found that people can drink up to 25 cups a day with “no damage” to their arteries – which typically increases your risk of stroke or heart attack.
Researchers from Queen Mary University of London split 8,412 participants into three groups (those who drink less than one cup a day, those who drink between one and three cups, and those who drink more than three) who then underwent MRI heart scans and infrared pulse wave tests.
Amazingly, they found “no increased stiffening” of arteries in people who drank even the full 25 cups, which contradicts previous studies on the topic (who are these people?).
But it’s not all good news. The research also indicated that the more enthusiastic coffee drinkers were also generally less healthy – they were much more likely to smoke and consume alcohol regularly.
Most health professionals still recommend that you stick to around 400mg of coffee daily (around four cups), to avoid any nasty caffeine side effects like headaches, restlessness or mood swings.
Upwards of 20? You might want to switch to decaf.
