A Tulane University study has found that dark chocolate poses no adverse health risks for adults and contains beneficial levels of essential minerals. Testing 155 chocolate samples for 16 metals, researchers discovered that only a few chocolates had concerning cadmium or lead levels, primarily impacting children. Despite some high lead levels in specific chocolates, none posed significant risks.
“For adults, there is no adverse health risk from eating dark chocolate, and although there is a slight risk for children in four of the 155 chocolate bars sampled, it is not common to see a 3-year-old regularly consume more than two bars of chocolate per week,” said lead author Tewodros Godebo, assistant professor of environmental health sciences at Tulane University School of Public Health and Tropical Medicine.
“Not only is it packed with these essential minerals, but they can potentially reduce the absorption of toxic metals in the intestine since these metals compete for the same site,” Godebo said. “But even for chocolates from South America, we found there is no adverse risk in eating an ounce per day,” Godebo said.
