A new South Korean study has claimed that drinking between 3-5 cups of coffee a day can lead to cleaner arteries and less chance of heart disease.

The study, published in the journal Heart, looked at over 25,000 adult male and females who drank between 3-5 cups of coffee a day and then used medical scans to asses their heart health, in particular the condition of the subject’s coronary arteries.

The researchers found that the people who drank a few cups of coffee a day exhibited less likelihood of showing the early signs of heart disease, and were less likely to have calcium deposits in their arteries than the people who drank more or no coffee cups of coffee at all.

British Heart Foundation senior dietician Victoria Taylor stated: “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.”

The results of the study contribute to an ongoing debate regarding the effects of coffee on physical wellbeing as some studies have linked daily moderate consumption of coffee to an increase in heart risk factors such as increased cholesterol or blood pressure.


When new studies like this are released it is important to remember that the results are never conclusive and stimulants like caffeine can affect people in different ways.

However, despite receiving negative press in the past it does seem that coffee (in moderation) can have a positive effect on health and wellbeing; considering the amount of coffee drunk at #JigsawHouse it is great news for #TeamJigsaw!
