Chocolate tied to decreased risk of irregular heart rhythm

Eating a small amount of chocolate every week or so may decrease the risk of a common and serious type of irregular heart rhythm, according to a new study of people in Denmark.

People who ate chocolate one to three times per month were about 10 per cent less likely to be diagnosed with atrial fibrillation than those who ate the sweet treat less than once a month, researchers found.

“As part of a healthy diet, moderate intake of chocolate is a healthy snack choice,” said lead author Elizabeth Mostofsky, of the Harvard T.H. Chan School of Public Health and the Beth Israel Deaconess Medical Center in Boston.

Past studies have that found eating chocolate – especially dark chocolate, which has more flavanols – is tied to better measures of heart health and decreased risk for certain conditions like heart attacks and heart failure, they add.
