Overview

• Analysis of 47,513 women from 1984 to 2016 defined healthy aging as living to 70 or older without 11 major chronic diseases and with preserved mental and physical function.
• Women consuming about 315 mg of caffeine per day—equivalent to three small cups of coffee—had higher odds of meeting the study’s healthy aging criteria.
• Each additional cup of caffeinated coffee was associated with a 2–5% greater likelihood of healthy aging, while tea and decaffeinated coffee showed no significant benefits.
• Each extra small glass of cola corresponded to a 20–26% lower chance of healthy aging, highlighting differences among caffeine sources.
• Genetic variations appeared to influence coffee’s protective effects, though overall lifestyle habits such as diet, exercise and avoiding smoking remained the strongest determinants of healthy aging.
