You might have seen the news report earlier this year, that toxic metals lead and cadmium were found in many popular chocolate products. Does this mean you should not eat chocolate?  Of course not! Let’s break down the facts:


In December 2022, Consumer Reports measured 28 dark chocolate bars and found cadmium and lead in ALL of them. The most popular ones were Dove, Hershey, Ghirardelli and Lily’s. Using, California’s maximum allowable dose level (MADL) for lead (0.5 micrograms) and cadmium (4.1 micrograms), Consumer Reports found the following:


Company/BrandLead % (High % in red)Cadmium %
Trader Joe’s Dark Chocolate 72% Cacoa26530
Trader Joe’s Dark Chocolate 72% Cacoa192136
Lindt Excellence Dark Chocolate 70% Cacoa48116
Dove Promises Deeper Dark Chocolate 70% Cacoa74112
Lily’s Extra Dark Chocolate 70% Cacoa14442
Godiva Signature Dark Chocolate 72% Cacoa14625
Lindt Excellence Dark Chocolate 85% Cacoa16680



Production Matters

How the chocolate is harvested and produced may increase the toxic metal content of the chocolate. Lead gets into the cacao beans after they are harvested, as the beans dry in the sun lead filled dust and dirt get onto the beans, manufacturers are working on shorter drying time to reduce lead. Cadmium is found in older cacao trees, therefore farmers are working on replacing with younger ones.



How Much is Too Much?

The FDA has issued guidance on acceptable concentrations of certain metals in food, but it doesn’t regulate chocolate. The FDA limits of lead are 2.2 micrograms (µg) per day for children and 8.8 µg per day for females of childbearing age. Eating an entire Trader Joe’s Dark Chocolate 72% Cacoa will yield a little over 1.5 micrograms of lead, under the FDA regulation.





Tips for Reducing Your Toxic Metal Exposure

Dark chocolate is safe in smaller amounts, though women who are pregnant or breastfeeding and children should limit their intake. Eat small servings of chocolate, yes like one of those mini Dove’ Chocolates.  If you must have chocolate daily, alternating with small amounts of milk chocolate and reduce your dark cacoa percentage, will decrease toxic metal exposure. Continue to work on eating a balanced diet high in iron, calcium and vitamin C which can help reduce toxic metal absorption.
