Heart Health and Chocolate

Chocolate, widely consumed throughout the year but commonly sent to a cherished one as a gift on Valentine's Day, has mixed benefits. In a recent meta-analysis, consuming chocolate in moderate amounts (< 100 g/wk) was associated with a reduced risk for cardiovascular disease, though the investigators cautioned that higher intakes might negate the benefits as a result of the higher sugar consumption.[11] Another recent study, a prospective cohort study conducted in over 30,000 men in Sweden, found a J-shaped relationship between chocolate intake and heart failure, concluding that consumption of smaller amounts was beneficial but the benefit was lost in those eating more than 1 serving/day.[12] For some patients, eating chocolate, which contains theobromine, a cardiac stimulant, has been linked with supraventricular tachycardia.[13]
