Three coffees a day cuts risk of heart attacks

Drinking three to five cups of coffee daily can cut the risk of clogged arteries that lead to heart attacks, a study has shown.

Researchers found those who drink a moderate amount each day are least likely to have ‘coronary calcium’ in their arteries – an early indicator of cardiovascular disease (CVD).

Blood vessels hardened and narrowed by such deposits can lead to clots which in turn can trigger a heart attack or a stroke.

The scientists studied a group of more than 25,000 Korean men and women with an average age of 41, who had no signs of heart disease.

Their coffee consumption was categorised as none, less than one cup a day, one to three cups a day, three to five cups per day and five or more per day.

They found the prevalence of detectable CAC was 13.4 per cent amongst the whole group while the average amount of coffee drunk was 1.8 cups per day.

Their findings showed the calcium ratios were 0.77 for people who had less than one cup per day, 0.66 for those having one to three cups every day, 0.59 for those consuming three to five cups per day, and 0.81 for people having at least five cups or more every day compared with non-coffee drinkers.

The U-shaped findings meant that those who drank one to three coffees a day had the second least prevalence of arteries that had clogged up.

The study, led by the Kangbuk Samsung Hospital in Seoul, South Korea, was published by the journal Heart. 

The authors concluded: ‘Our study adds to a growing body of evidence suggesting that coffee consumption might be inversely associated with CVD (cardiovascular disease) risk.


‘Further research is warranted to confirm our findings and establish the biological basis of coffee’s potential preventive effects on coronary artery disease.’

‘We need to take care when generalising these results because it is based on the South Korean population, who have a different diet and lifestyle.’
