According to a new analysis of a series of studies which looked at caffeine intake, it seems that drinking about three cups of coffee each day might actually be good for the heart. Moderate intake of caffeine might decrease the risk of developing abnormal heart rhythms. It’s interesting that cardiologists usually advise people with arrhythmias to avoid caffeine by all means. However, this analysis which a group of Australia cardiologists conducted suggests otherwise.
In fact, these experts think that caffeine might actually help protect the heart against some potentially fatal problems. According to their research, it seems that caffeine actually blocks the effect of adenosine once inside the body. This is the chemical that usually increases the risk of developing arrhythmias. A particular study which involved a number of 228,465 people showed that regular coffee drinkers actually had a smaller chance of developing irregular or faster heart rhythms. Another study, on a smaller number of people, showed an even smaller chance than the first one. According to Dr. Peter Kistler, the leader of the study, there is this common idea, not based on any scientific evidence, that caffeine negatively affects your heart rhythms.
Three cups of coffee per day might be good for your heart
It’s interesting that after extensively reviewing the medical literature, the team of experts did not find anything that pointed towards coffee being bad for your heart. Only two studies that they included in their analysis showed a greater risk of arrhythmias. However, this only happened when the patients drank nine to ten cups of coffee each day.
The new review claims that three cups of coffee per day should be the safe amount, even for people who suffer from irregular heartbeats. Still, this doesn’t mean that anyone who knows they have heart problems shouldn’t speak with their doctor first.
