Overview

  • Each additional cup of caffeinated coffee per day in midlife was associated with a 2% to 5% higher likelihood of reaching age 70 free of major chronic diseases and with maintained cognitive, mental and physical function.
  • The study defined healthy aging as survival to at least 70 years without 11 chronic illnesses alongside preserved mobility, mental health and cognitive ability.
  • Researchers found no significant healthy-aging benefits from decaffeinated coffee or tea consumption.
  • Each small glass of soda correlated with a 20% to 26% lower chance of healthy aging, underscoring that not all caffeine sources confer the same effects.
  • Investigators emphasize that up to two cups of coffee daily are generally safe and note that genetic differences can influence individual responses to caffeine.
