Scientists from the Queen Mary University of London found that having up to three cups of coffee a day has a protective effect on heart health.
It also reduces the overall mortality rate and the risk of stroke.
The research is published in the European Journal of Preventative Cardiology and was conducted by Professor Steffen Petersen et al.
In the study, the team analyzed data from 468,629 UK Biobank participants, who didn’t have any record of heart disease at the start of the research period.
The participants were asked about their coffee-drinking habits and lifestyle in a detailed questionnaire and data was also gathered on their heart health levels.
They were divided into three groups: non-coffee drinkers, light to moderate coffee drinkers, and those who consumed a significant amount of coffee a day.
The team found that light to moderate coffee drinking was linked to a 12 percent lower risk of overall mortality, and a 17 percent lower risk of death caused by heart diseases compared to non-coffee drinkers.
In addition, drinking from half to three cups of coffee was linked to a 21 percent lower risk of stroke.
The team also found that most people drank either ground or instant coffee.
Ground coffee in moderate amounts was linked to lower mortality risk—but this benefit was not found among the regular instant coffee drinkers.
Using the MRI scans, the team found that regular light to moderate coffee consumption is beneficial for the health of the heart, with the suggestion that it can slow down age-related cardiac changes.
The researchers also found that the type of coffee matters in relation to health benefits.
The research also found that even decaffeinated coffee was associated with lower all-cause mortality risk which also suggests that it’s not only the caffeine that plays a role in the positive effects of coffee.
