New research suggests that moderate coffee consumption may support healthy aging. A 30-year study of nearly 50,000 women found that those who drank regular coffee during midlife were more likely to age well physically, mentally, and emotionally.
Researchers measured caffeine intake and followed the women’s health over three decades. The study found that most women who reached age 70 without serious disease did so after consuming about 315 milligrams of caffeine per day, roughly three small cups of coffee. Tea, soda, and decaffeinated coffee didn’t show the same effect.
The benefits of coffee on aging were unique to caffeinated coffee and not influenced by tea or decaf. The study suggests that moderate coffee consumption may preserve both mental and physical function in older adults.
However, not all people benefit equally from coffee. A second study found that slow metabolizers of caffeine – those with a specific gene variation – were at higher risk for kidney problems when consuming large amounts of coffee. Fast metabolizers didn’t experience this increased risk.
While coffee may offer some benefits, researchers emphasize the importance of overall healthy habits, such as regular exercise and a balanced diet. Healthy aging is not dependent on a single habit or drink but rather years of daily decisions that build something powerful over time.
