Sept.1, 2010 (Stockholm, Sweden) — Older people with high blood pressure who drink one to two cups of coffee a day have more elastic blood vessels than people who drink less or more, Greek researchers report.

As we age, our blood vessels get stiffer, and that’s thought to increase the risk of high blood pressure. The new findings suggest moderate coffee drinking may counteract this process.

Previous research has shown conflicting results as to whether coffee is good or bad for the heart.

The new study involved 485 men and women, aged 65 to 100, who live on a small island called Ikaria, in the Aegean Sea, where more than a third of people live to celebrate their 90th birthday.

“We were aiming to evaluate the secrets of the long-livers of Ikaria,” says study head Christina Chrysohoou, BSc, of the University of Athens.

She presented the findings at the European Society of Cardiology Congress.

Coffee Improves Blood Vessel Elasticity

Participants, all of whom had high blood pressure, underwent imaging scans to measure the stiffness of their blood vessels.

Of the total, 33% of participants drank no coffee or less than one cup of coffee a day, 56% drank one to two cups, and 11% drank three or more cups a day.

People who drank one to two cups of coffee a day had about a 25% greater elasticity in their major blood vessels than people who drank less coffee or none at all.
