Three to five cups of coffee is all you need to avoid clogged arteries and shun the risks of heart attacks according to Korean researchers in a recent study. The study was carried out on more than 25,000 male and female employees, who underwent routine health checks at their place of work. The new study only goes to question earlier studies that had indicated a potential increase in heart disease on consumption of coffee.

The study found out that employees who consumed moderate amount of coffee of three to five cups a day were less likely to suffer from heart disease on medical scans. The findings only goes to open a long-running debate on the benefits and disadvantages of consuming coffee. Stimulant Caffeine is found in Coffee among a number of other compounds, but studies have never made it clear on whether they can cause good or harm to the body.

Coffee consumption in a number of studies has been attributed to improved levels of insulin sensitivity and reduced risks of type 2 diabetes. Other studies have questioned its intake especially after being linked to increased cholesterol concentrations, as well as increased blood pressure.

In the latest study, researchers concentrated their attention on studying arteries to look for any diseases on users who took coffee. None of the surveyed 25,000 employees were found to have any outward signs of artery disease on medical scans although ten were found to have small deposits of calcium on their scans. Calcium deposits have been found to cause the hardening and narrowing of the arteries, most of the time leading to a strokes or heart attacks.

People who took few cups of coffee were less likely to have calcium deposits according to the study when compared to people who consumed more cups. The researchers, however, agree that more studies are needed to confirm this theory.
