Coffee sparks endless debate: too much can elevate cardiovascular risks as a stimulant (dose varies by metabolism), yet moderate amounts support heart health and longevity. Two landmark studies—one in the US, one in the UK—now substantiate that about three cups daily may extend life expectancy.
The UK study monitored 520,000 people aged 35+ across 10 European countries for nearly 16 years. The US study followed 186,000 participants for over 16 years. Key finding: three-cup drinkers faced an 18% lower mortality risk in both. UK women saw an 8% drop—still notable. Authors stress this is observational, not causal; coffee drinkers may have other healthy habits. Still, regular intake correlates with fewer cardiovascular, respiratory, and kidney issues. Crucially, benefits trace to antioxidants, not caffeine—regular and decaf performed equally.
These results don't greenlight all-day coffee marathons, but they bolster the case for your daily ritual when skeptics ask, "Coffee again?!"
