The newly published study of young, healthy adults across South Korea found that, in comparison with people who do not drink coffee, those who drank between three and five cups per day experienced a lower risk of developing calcium deposits within their coronary arteries, which is a heart disease indicator.
The study’s participants who consumed between 3 and 4 cups of coffee per day had the lowest risk of clogged arteries developing, said the lead doctor in the research at John Hopkins University.
However, the risk dropped with just one cup daily, compared to those who did not drink any coffee, said researchers. Still, the team of researchers stopped short of making recommendations that people drink coffee as a way to prevent development of heart disease.
At one time, it was thought that consuming coffee would make a person prone to having heart attacks. However, a growing amount of evidence suggests drinking coffee has a beneficial or neutral effect on the health of the cardiovascular system.
Analysis of 36 previous studies found a moderate consumption of coffee was linked to a lower heart disease risk and other previous studies have found a link between consuming coffee and a reduction of the risk of developing type 2 diabetes.
However, the beverage has been linked as well to an increased amount of LDL cholesterol or the bad cholesterol, and higher blood pressure.
In the latest research, Guallar and his colleagues in South Korea studied over 25,000 males and females who had undergone routine examinations.
None of the participants had heart disease signs and the average age of the group was 41 when the study started.
After the study, it was found that those who drank between 3 and 5 cups of coffee each day had 40% less calcium within their arteries than participants who did not drink any coffee.
