Coffee drinkers have "cleaner" arteries
Yet more good news for coffee drinkers. A new study in South Korea concludes that drinking coffee regularly may help prevent clogged arteries, a known risk factor for heart disease. The findings were published in the journal Heart.
The study analyzed more than 25,000 men and women who underwent health checkups at work. The researchers found that those who drank three to five cups of coffee per day were less likely to show signs of early heart disease on their diagnostic scans. The researchers looked particularly at potential damage to the coronary arteries, which supply the heart, by testing for tiny deposits of calcium in the artery walls. No participants had outward signs of heart disease, but one in 10 tested positive for calcium deposits.
Using these scans, the researchers then compared the results to coffee drinking habits. They also accounted for other risk factors, such as smoking and family history. They found people who drank a couple cups of coffee per day were less likely to have calcium deposits in their arteries compared to people who drank little or no coffee.
The researchers said more research is needed to better understand this possible connection. It's one of several recent studies that have suggested that there are health benefits to drinking coffee regularly.
