Good news for Coffee drinkers - a few cups a day may be good for the heart

Drinking a few cups of coffee a day may help people avoid clogged arteries - a known risk factor for heart disease - Korean researchers believe.

They studied more than 25,000 male and female employees who underwent routine health checks at their workplace.

Employees who drank a moderate amount of coffee - three to five cups a day - were less likely to have early signs of heart disease on their medical scans.

The findings reopen the debate about whether coffee is good for the heart.

Heart effects

There is a lot of confusion when it comes to the effect of coffee on heart health.

In heart disease, the arteries supplying the heart muscle can become blocked

Some studies have linked consumption to heart risk factors, such as raised cholesterol or blood pressure, while others suggest the beverage may offer some heart protection.

But there is no conclusive evidence either way, and the latest research from South Korea, which is published in the journal Heart, only adds to the discussion.

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.

The study authors say more research is needed to confirm and explain the link.

Coffee contains the stimulant caffeine, as well as numerous other compounds, but it's not clear if these might cause good or harm to the body.

Victoria Taylor of the British Heart Foundation said: "While this study does highlight a potential link between coffee consumption and lower risk of developing clogged arteries, more research is needed to confirm these findings and understand what the reason is for the association.

"We need to take care when generalising these results because it is based on the South Korean population, who have different diet and lifestyle habits to people in the UK."
