New research suggests cocoa compounds may offer heart-health benefits

Trick-or-treating on October 31st? Though we usually recommend choosing fruit over candy, there may be reason to enjoy a little chocolate this Halloween. A 2026 study published in the European Journal of Epidemiology offers new evidence that natural compounds found in cocoa may be good for your heart.

This study took a look at research involving more than 21,000 older adults who were followed for 3.6 years. Participants received either a daily cocoa extract supplement or a placebo (a pill with no active ingredients). Earlier findings showed that those taking cocoa extract had a 27% lower risk of dying from heart-related causes. This time, researchers looked more closely at heart attacks, strokes and other heart-related problems. They found that people taking cocoa extract had slightly better overall heart-health outcomes than those taking the placebo, strengthening the evidence that cocoa compounds may offer some cardiovascular benefits.

But is chocolate really a treat without a trick? While the findings are promising, researchers studied cocoa supplements, not chocolate bars, so eating chocolate may not offer the same benefits. Plus, chocolate can contain added sugar, calories and saturated fat, making portion size important. If you're craving something sweet, consider dark chocolate with at least 70% cocoa and enjoy a small portion, about half an ounce. Keep in mind that the amount of potentially beneficial cocoa compounds can vary depending on how chocolate is made.
