new study from Harvard researchers suggests moderate chocolate intake is associated with a significantly lower risk for irregular heartbeats.

To be clear: there’s good reason to be skeptical of sensationalist science headlines claiming disasters and/or miracles linked to foods, social behaviors, and a whole host of other bizarre things. But sometimes research adds up to a compelling picture of health links.

The analysis conducted by Harvard T.H. Chan School of Public Health and Danish scientists involved more than 55,500 people. Those who ate two to six servings per week had a 20% lower chance of the irregular heartbeats, or atrial fibrillation, one of the major contributors to clots, stroke, and heart failure. Slightly lower, regular chocolate consumption showed similar (albeit less pronounced) results, according to the research published in the BMJ.

And it’s not the first such analysis to imply this connection (once again: correlation doesn’t imply causation). “Our study adds to the accumulating evidence on the health benefits of moderate chocolate intake and highlights the importance of behavioral factors for potentially lowering the risk of arrhythmias,” said lead study author Elizabeth Mostofsky, as the Harvard Gazette reports.
