For many of us, chocolate is more than just a tasty treat. It’s a mood lifter, an energy booster, a reward after a tough day, a favorite holiday gift.
People also choose dark chocolate in particular for its potential health benefits, thanks to studies that suggest its rich supply of antioxidants may improve heart health and other conditions, and for its relatively low levels of sugar. In fact, more than half of people in a recent survey from the National Confectioners Association described dark chocolate as a “better for you” candy.
But there’s a dark side to this “healthier” chocolate. Research has found that some dark chocolate bars contain cadmium and lead—two heavy metals linked to a host of health problems in children and adults.
The chocolate industry has been grappling with ways to lower those levels. To see how much of a risk these favorite treats pose, Consumer Reports scientists recently measured the amount of heavy metals in 28 dark chocolate bars. They detected cadmium and lead in all of them.
