COFFEE and tea drinkers can, and should, sip worry — free — regular caffeine consumption doesn’t cause heart palpitations, and likely has cardiovascular benefits, according to a new study.
“In general, consuming caffeinated products every day is not associated with having increased … arrhythmia but cannot specify a particular amount per day,” lead researcher Dr. Gregory Marcus wrote in the Journal of the American Heart Association.
Their findings go against the conventional clinical knowledge in
the medical world that caffeine causes palpitations, which can lead to more chronic problems including heart failure or arrhythmias.
The researchers looked for heart irregularities — premature ventricular and atrial contractions — in the participants over a year, but found that there were no differences among the participants, average age 72, regardless of their caffeine intake.
In fact, they discovered that “habitual coffee drinkers” actually have less of a chance of developing coronary artery disease.
“Recommendations advising against the regular consumption of caffeinated products to prevent disturbances of the heart’s cardiac rhythm should be reconsidered, as we may unnecessarily be discouraging consumption of items like chocolate, coffee and tea that might actually have cardiovascular benefits,” according to Marcus.
The study didn’t look into the effects of powdered caffeine used in energy drinks, but the Food and Drug Administration in the US has warned against its potentially deadly side effects.
