Are you somebody that cannot do without a few cups of coffee throughout the day to keep you going? If so, you may be cheered to hear that a new study has suggested drinking three to five cups of coffee a day reduces the risk of clogged arteries and heart attacks.
In a study of more than 25,000 people, those who drank a moderate amount of coffee – defined as three to five cups daily – were less likely to have calcium deposits in their coronary arteries than those who drank no coffee or more coffee daily.3
A large part of arterial plaque consists of calcium deposits (atherosclerosis), hence the term "hardening of the arteries." Coronary artery calcium can be a significant predictor of future heart disease risk.
The study suggests moderate coffee consumption may lower your risk of clogged arteries and related heart attacks. The researchers noted:4
“Our study adds to a growing body of evidence suggesting that coffee consumption might be inversely associated with CVD [cardiovascular disease] risk.”
Past research has also found that coffee appears to have a protective effect on the heart. For instance, one study showed moderate coffee drinking reduces your chances of being hospitalized for heart rhythm problems.5 Another study found it may trigger a 30 percent increase in blood flow in your small blood vessels, which might take some strain off your heart.6
