Drinking coffee can reduce the risk of developing abnormal heart rhythms.
A study conducted by the University of California assessed the impact of coffee consumption on arrhythmia incidence on more than 380,000 people and found that drinking an additional cup on a daily basis lowers the risk of an irregular heart rhythm by three per cent.
Dr. Gregory Marcus, who co-authored the study, said: "We see no evidence for this broad-based recommendation to avoid coffee or caffeine.
"There could be some individuals where caffeine is their trigger, but I think the growing evidence is those cases are actually quite rare."
"The majority of people, even those with arrhythmias, should be able to enjoy their cup of coffee, and maybe there are some people for whom caffeine or coffee may actually help reduce their risk."
