Can Daily Coffee Help You Live to 90?

What if your morning coffee routine was secretly adding years to your life? On the Greek island of Ikaria, a remarkable number of residents live well into their 90s—about one in three—while enjoying far lower rates of cancer, heart disease, and dementia than most Western populations. Could their daily coffee habit hold the secret?

Yes—researchers found that drinking 1–2 cups of black coffee per day is linked to healthier arteries and greater longevity. But more than three cups may reduce those benefits.

The Island Where People Live to 90

Greek researchers have long studied Ikaria, one of the world’s five identified “blue zones” where people regularly reach age 90 or older. Around a third of Ikarians hit that milestone, and they experience 20% lower cancer rates and 50% fewer heart attacks compared to Western populations. Strikingly, dementia is nearly absent. Scientists now believe their coffee consumption plays a role.

Coffee and Arterial Health in Older Adults

In a study led by the University of Athens, researchers examined 485 Ikarian adults aged 65 to 100, all with hypertension—a condition that typically stiffens arteries and raises risks for heart disease and stroke. Surprisingly, 56% of participants had arteries as flexible as those of much younger people. These individuals reported drinking 1–2 cups of coffee daily. Meanwhile, the 10% who drank more than 3 cups per day had the least elastic arteries.

The difference appears tied not just to coffee, but specifically to how it’s consumed: mostly black, and in moderation.

How Much Coffee Is Ideal?

Dr. Christina Chrysohoou of the University of Athens, who led the study, recommends 25–50 milliliters of black coffee per day as the optimal amount. That’s roughly 1–2 small cups. The antioxidants and caffeine in coffee contribute to improved arterial function, but exceeding that amount doesn’t boost benefits—and may even be counterproductive.

Beyond the physical effects, coffee also fosters social interaction. Enjoying a cup in a café with friends contributes to mental wellbeing, another key factor in healthy aging.

What This Means for Your Daily Cup

If you’re aiming for a long, healthy life, your coffee routine might matter more than you think. The Ikaria study suggests that 1–2 cups of black coffee daily—rich in antioxidants and free from excessive additives—can support arterial elasticity and potentially add healthy years. Just avoid overdoing it: more than three cups may undermine the benefits.

Frequently Asked Questions

How many cups of coffee did the long-lived Ikarians drink?

Most of the Ikarians with the healthiest arteries drank 1–2 cups of black coffee per day. About 56% of study participants in this group had unusually elastic arteries for their age. Those drinking over 3 cups daily had less favorable arterial health.

What type of coffee is best for longevity?

The study highlights black coffee—without sugar or milk—as most beneficial. The antioxidants and moderate caffeine levels are thought to support artery function. Additives or excessive consumption may reduce or reverse the positive effects.

Does coffee really improve artery health?

Yes, according to the Athens study. Participants who drank 1–2 cups of black coffee daily showed better arterial elasticity, especially compared to those who drank more than three cups. Coffee’s antioxidants and caffeine are believed to enhance blood vessel function.

Can coffee help prevent dementia?

The Ikaria study noted almost no dementia among residents, and while many factors may contribute, regular black coffee consumption—along with strong social ties—could play a protective role. However, the study didn’t isolate coffee as the sole cause.

Is 3 cups of coffee a day too much?

For arterial health, yes. In the study, participants who drank more than 3 cups daily had the worst arterial elasticity. Researchers recommend limiting intake to 25–50 ml (about 1–2 cups) of black coffee per day for optimal benefits.
