Scientists find heavy metals in dark chocolate

New research highlights the presence of heavy metals like lead and cadmium in dark chocolate, though experts suggest that modest consumption poses little risk.

Dani Blum reports for The New York Times.


In short:

  • A recent study found that 43% of dark chocolate products tested contained lead levels above California’s Proposition 65 limits, while 35% exceeded cadmium limits.
  • Although organic products showed higher concentrations, the average consumer likely faces no immediate risk from moderate chocolate consumption.
  • Pregnant women and young children should exercise caution, as they are more susceptible to the adverse health effects of heavy metals.

Key quote:

“Just the fact that it exists doesn’t necessarily mean immediately there’s going to be some terrible health consequence.”

— Laura Corlin, associate professor of public health, Tufts University

Why this matters:

For chocolate lovers, this doesn’t necessarily mean waving goodbye to your favorite treat. Awareness and moderation are key. Opt for brands that source cocoa from regions with lower heavy metal content and prioritize companies that are transparent about their testing for contaminants. Read more: Feeling old?
