In the past, there have been numerous studies that attributed coffee as one of the factors that contribute to heart disease. It was an argument back then when coffee was thought to cause high cholesterol and also elevated blood pressure in drinkers.
A recent study by Korean researchers has said otherwise. This study has once again opened the debate about whether coffee is good for the heart or not.
This could be good news for coffee drinkers as this study involves coffee drinking and clean arteries. They found that those who regularly drink coffee have arteries that could be unclogged, decreasing the chances of heart disease, based on the 25,000 respondents, both men and women, who had routine checks performed at their workplace.
The study showed that the participants who drank between 3 to 5 cups of coffee in a day showed better results on their medical scans.
The researchers used medical scans to look for any diseases of the arteries that supply the heart. In coronary disease the arteries become clogged up by the gradual build-up of fatty materials within their walls. Tiny deposits of calcium in the walls can be an early indication that this disease may be starting.
The results showed that none of the employees in the Korean study had outward signs of heart disease but that more than one in 10 did have visible calcium deposits.
The researchers then compared the scan results with the employees’ self-reported daily coffee consumption, taking into account other potential heart risk factors such as exercise, smoking and family history of heart problems. The final results showed that people who drank a few cups of coffee a day were less likely to have calcium deposits in their coronary arteries than people who drank more than this or no coffee at all.
As a recommendation for the results of the study, there is more research needed to confirm this link as other factors such as gender, location, diet and lifestyle have not been included in the study.
