The American Heart Association has concluded that drinking up to five cups of coffee daily — roughly 400 milligrams of caffeine — is safe for most adults. Published in the journal Circulation, the statement draws on decades of research linking moderate coffee consumption to meaningful health benefits. Studies found a 21% lower stroke risk, a 30% lower type 2 diabetes risk, and a 39% lower recurrence rate of atrial fibrillation after treatment. However, energy drinks and high-dose caffeine capsules raise separate concerns, with case reports linking them to serious heart events. Brewing method also matters — unfiltered coffee raises LDL cholesterol, while paper-filtered coffee does not. Genetics influence how individuals respond to caffeine, with heredity accounting for 30% to 50% of caffeine sensitivity. Story URL
