According to new research release by Consumer Reports, some dark chocolate contains potentially dangerous amounts of heavy metals.
The amount of heavy metals in 28 popular brands of dark chocolate bars were studied and cadmium and lead were present in all, some with harmful levels of at least one metal.
“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.
CR found that an ounce of Hershey's Special Dark Mildly Sweet Chocolate contained lead 265% above what California allows, and Trader Joe's Dark Chocolate 72% Cacao holding 192% more.
According to CR's findings, the safer choices are:
Mast Organic Dark Chocolate 80% Cocoa. CR found an ounce contained 14% less lead and 40% less cadmium than California's allowable limits.
