Drinking Coffee Boosts Blood Flow, Study Says

by Rachel Baker on November 21, 2013

It looks as though drinking coffee may not be a bad thing for cardiovascular health.

Drinking a cup of caffeinated coffee significantly improved blood flow in a finger, found the study of 27 adults.

Researchers in Japan, led by Masato Tsutsui, cardiologist and professor in the pharmacology department at the University of the Ryukyus, found that people who drank a cup of caffeinated coffee had a 30 percent increase in blood flow over 75 minutes.

“This gives us a clue about how coffee may help improve cardiovascular health,” Tsutsui said in the study announcement.

“The study adds to a growing body of research about coffee, the world’s most widely consumed beverage,” according to the American Heart Association, which published the study announcement. “Previous studies showed that drinking coffee is linked to lower risks of dying from heart disease and stroke, and that high doses of caffeine may improve the function of larger arteries.”

Tsutsui said it’s unclear how caffeine works to improve the function of small blood vessels, but that caffeine may open up the vessels and reduce inflammation.
