The news source reports that the research focused on 485 participants, men and women between the ages of 65 and 100 who presented high blood pressure.
The subjects underwent imaging scans to reveal the level of stiffness of their blood vessels, which is a common sign of aging.
The study found that the 56 percent of those who drank one or two cups a day had about 25 percent greater vessel elasticity, which can reduce high blood pressure.
"We recommend hypertensive patients drink coffee in moderation, just one to two cups a day, as it seems that it may improve arterial aging," study head Christina Chrysohoou told the news source.
Along with possibly lowering blood pressure, CNN reports that coffee has also shown potential for other health benefits. Drinking moderate amounts of coffee may also reduce the risk of prostate cancer, and middle-aged people who drank three-to-five cups a day showed the lowest risk for developing Alzheimer's disease.
