The “black gold” is a stimulant and provides energy. U.S. researchers have studied how coffee affects the heart.
Much has been written about coffee. Some drink it to wake up in the morning, others just for fun. Or something cafe-free, because otherwise too much of the drink – a centuries-old fear – would beat the heart faster. It is widely believed that coffee increases the risk of irregular heartbeat. However, the evidence for this is not yet sufficient. What does the cafe boost really do to the heart? Researchers have investigated this question.

Coffee, as we know it today, has many positive properties, it has anti-oxidant and anti-inflammatory effects. It is now believed that coffee drinkers are less likely to develop cancer, diabetes and Parkinson’s disease.
Coffee, (not) an affair of the heart
386,258 people participated in the study, which was published in JAMA Internal Medicine. For a good three years, the researchers focused on brain arrhythmias, which may also include atrial fibrillation. Participants were between 40 and 69 years old and drank an average of two cups of coffee a day. Factors such as demographics, lifestyle, diseases and conditions that can cause heart palpitations were included.
According to the study, each cup of coffee consumed in addition to the usual amount reduced the risk of arrhythmias by as much as three percent, according to Gregory Marcus, a professor in the Department of Cardiology at the University of California, San Francisco, in the study. ,
Up to five cups a day
But that does not mean that liters of coffee should be drunk indefinitely. From a healthcare point of view, there is nothing wrong with a maximum of five cups of coffee a day – provided you are healthy and do not take any medicines or medicines related to coffee. This is what Hans Hauner, director of the Else Kröner Fresenius Center for Nutritional Medicine at the Technical University of Munich, told “Welt”.
