Long viewed as healthier than other sweet treats, some brands of dark chocolate contain potentially dangerous amounts of heavy metals, according to research released on Thursday by Consumer Reports.
Scientists at the nonprofit advocacy organization recently measured the amount of heavy metals in 28 popular brands of dark chocolate bars and found cadmium and lead in all of them. For 23 of the bars, consuming just an ounce a day would put an adult over a level for at least one of the metals that could be harmful, CR said. Five of the bars were above those levels for both cadmium and lead.
Long-term exposure to even small amounts of heavy metals can lead to a slew of health issues, including developmental problems and brain development in young children, experts say.
