Coffee isn’t just a quick energy boost—it might also support healthier aging. A recent study presented at the American Society for Nutrition’s annual meeting followed over 47,000 women and found that those who regularly drank coffee were more likely to enjoy better health in their later years. While the research is observational, it adds to growing evidence that moderate coffee consumption could have long-term benefits.
Researchers tracked female nurses from the 1970s through 2016, analyzing their caffeine intake and overall health. Women who consumed the most caffeine—nearly seven small cups of coffee daily—had a 13% higher likelihood of meeting criteria for healthy aging compared to those who drank less than one cup per day.
Healthy aging in this study meant being age 70 or older, in good physical and mental health, free of cognitive decline, and without major chronic illnesses like cancer, diabetes, or heart disease.
Interestingly, these benefits were primarily linked to caffeinated coffee. Tea, decaf coffee, and cola were not associated with similar results—and cola was linked to lower odds of healthy aging.
This study aligns with past findings. Multiple large-scale studies suggest coffee drinkers may have lower risks of early death and chronic conditions such as:
Heart disease
Type 2 diabetes
Parkinson’s disease
Liver disorders
Osteoporosis
Certain cancers
One study even found that moderate coffee drinkers (one to three cups daily) were 15% less likely to die within the next decade than non-drinkers—unless they added excess sugar or high-fat creamers.
While researchers don’t fully understand how coffee helps, caffeine may play a key role. Some studies suggest it protects brain cells and may reduce the risk of diseases like Parkinson’s. Additionally, coffee contains compounds that could reduce inflammation and protect against cellular damage.
Though this particular study didn’t show benefits from decaf coffee, other research has linked both decaf and regular coffee to reduced disease risk.
Experts say these findings are encouraging, but coffee isn’t a cure-all. If you already enjoy coffee, these insights may support your habit—as long as you keep cream and sugar in check. But if coffee makes you feel anxious or affects your sleep, there’s no need to force it into your routine.
Healthy aging still depends on fundamentals like a balanced diet, regular exercise, quality sleep, and social connection.
