The study of 25,000 adults, carried out by researchers from Kangbuk Samsung Hospital in South Korea, found that people who drink 3-5 cups of coffee a day were less likely to have the first signs of heart disease.
According to The Daily Mirror: “3 coffees a day cuts the risk of heart disease and strokes”.
The average age of the adults in the study was 41 years and 83.7% were male. After adjusting the results for a range of potential confounding factors, compared to people who did not drink coffee:
- people who drank between 3 and 5 cups of coffee were 19% less likely to have calcium in the coronary arteries
- there were no statistically significant changes in risk for people who drank less than one cup, between 1 and 3 cups or 5 or more cups of coffee
Although this could be great news for coffee lovers, unfortunately the data only looked at one point in time and so it cannot prove that drinking 3 to 5 cups of coffee each day is good for the heart.
With the study continuing, we may have more evidence in the future!
