Could your daily cup of coffee be the secret to a long and healthy life?
According to new research presented at the Nutrition 2025 conference, coffee might be more than just a pick-me-up — it could be a powerful tool for healthy aging in women.
Coffee linked to healthy aging
A large-scale study involving over 47,000 women found that those who regularly drank coffee had a higher chance of achieving what researchers defined as "healthy aging".
This means living to at least 70 without major chronic diseases, cognitive decline, or physical limitations.

Every cup counts
Researchers discovered that each additional daily cup of coffee was associated with approximately a 2 % increase in the chances of healthy aging.
While the effect is modest, it can add up significantly over time.
Only caffeinated coffee showed benefits
The health advantages were only linked to caffeinated coffee.
No similar effect was found among those who drank decaffeinated coffee or tea, suggesting that caffeine — and possibly other active compounds in coffee — plays a crucial role.

Cola may reduce healthy aging chances
Women who frequently consumed cola had a 20 % lower chance of experiencing healthy aging.
This points to a possible long-term health risk associated with sugary soft drinks.
Long-term data strengthens the findings
The study drew on data collected over 30 years, using food frequency questionnaires from 1984, 1986, 2014, and 2016.
This extensive timeframe offers a deeper understanding of participants’ habits and health outcomes.

Physical and mental well-being were key metrics
Women with higher coffee intake scored better in areas such as physical functioning, cognitive performance, and mental health — all essential components of healthy aging.
Median caffeine intake was 315 mg daily
This translates to roughly three to four cups of coffee per day. That level of caffeine consumption was most strongly associated with the benefits observed in the study.
Genetics may impact the effects
Not all women benefit equally.
Those with slower caffeine metabolism — often due to a genetic variation in the CYP1A2 gene — may be more susceptible to the negative effects of high caffeine intake.

Coffee additives may influence results
While coffee appears beneficial, the study did not clarify how additives like sugar, cream, or milk may have affected the outcomes.
These factors could potentially alter coffee’s health effects.
Findings are not yet peer-reviewed
Although promising, the study has not yet been published in a peer-reviewed journal.
Until further research confirms these results, conclusions should be considered preliminary.
