How Drinking Coffee May Help You Live Longer

On the Greek island of Ikaria, one-third of residents live to 90 or older—and many avoid common age-related diseases. With cancer rates 20% lower and heart disease 50% lower than in Western countries, plus almost no dementia, researchers wondered: could daily coffee habits play a role? The answer may lie in how they brew and drink it.

Yes—drinking 1 to 2 cups of traditional Greek coffee per day is linked to better arterial health and lower risks of heart disease, dementia, and early death. But more than 3 cups may harm artery elasticity. The key is moderate intake of unfiltered coffee rich in protective compounds.

What Makes Ikaria’s Coffee Habits Special?

Greek islanders, particularly those on Ikaria, enjoy some of the longest lifespans in the world. Remarkably, around 33% reach age 90, while suffering far less from cancer, heart disease, and dementia compared to Western populations. Researchers have investigated lifestyle factors—including diet and coffee consumption—to explain this remarkable health profile.

The Science: Coffee and Arterial Health

A study led by Dr. Christina Chrysohoou from Athens University focused on 485 Ikarian residents aged 65–100 with high blood pressure. Surprisingly, 56% had arteries as healthy as those of much younger people. These individuals reported drinking 1–2 cups of traditional Greek coffee every day. Another 10% drank over 3 cups daily—but their arteries showed the worst elasticity.

Traditional Greek coffee is prepared unfiltered, using a small brass or copper device called a briki. This method leaves more beneficial compounds in the cup compared to filtered brewing. The coffee retains higher levels of polyphenols, antioxidants, and other microelements that contribute to cardiovascular protection.

How Coffee Supports Heart and Longevity

Dr. Chrysohoou explained that moderate coffee intake improves the function of the aorta—the body’s main artery—by enhancing its ability to expand and contract. This “arterial elasticity” is a key marker of cardiovascular health. The caffeine and antioxidants in coffee appear to directly benefit arterial function. However, the study found that excessive consumption (more than 3 cups per day) negates these benefits and may actually reduce arterial elasticity.

Beyond physical effects, the social aspect of coffee drinking also matters. In Greece, coffee is often enjoyed slowly in social settings like cafes. These moments of relaxed conversation contribute to mental well-being, which is increasingly recognized as part of healthy aging.

Key Takeaways From the Research

• Ikarian locals drinking 1–2 cups of traditional Greek coffee daily had significantly healthier arteries.
• Unfiltered brewing retains more heart-healthy compounds compared to filtered coffee.
• Moderate coffee intake supports arterial elasticity and may reduce risks of heart disease and cognitive decline.
• Drinking more than 3 cups per day was associated with poorer arterial outcomes.
• Social coffee rituals may further enhance the mental health benefits of drinking coffee.

Frequently Asked Questions

What kind of coffee did the Ikarians drink?

The Ikarians drank traditional Greek coffee, which is a dark, unfiltered brew similar to Turkish coffee. It is made using finely ground coffee boiled in a briki and served unfiltered, meaning more oils and compounds remain in the cup.

How many cups of coffee are linked to better health in the study?

Drinking 1 to 2 cups of traditional Greek coffee per day was associated with better arterial health and lower risks of heart disease and dementia. More than 3 cups per day was linked to worse arterial elasticity.

Why is unfiltered coffee better for your arteries in this study?

Unfiltered Greek coffee retains more antioxidants and bioactive compounds that support arterial function. These compounds are removed by paper filters used in other brewing methods.

Does caffeine alone improve longevity?

No, it’s not just the caffeine. The antioxidants and other compounds in traditionally brewed Greek coffee also contribute to improved arterial health and overall longevity benefits observed in the study.

Does the social aspect of coffee drinking matter?

Yes. The study noted that coffee drinking in Greece is often a social activity, which contributes to mental well-being—an important factor in healthy aging.
