A recent study published in the journal Frontiers in Nutrition found that dark chocolate, including organic varieties, is contaminated with lead and cadmium. These metals can cause cancer, chronic diseases, and developmental problems in children.
The study looked at 72 dark chocolate products over eight years. It found that 43% exceeded California’s Proposition 65 limits for lead, and 35% for cadmium. Organic dark chocolate often had the highest levels of these metals.
Lead and cadmium enter the soil from industrial pollution and fertilizers, making it hard to avoid contamination. However, even chocolate grown in less polluted areas was found to contain these metals.
Key Points:
- Dark chocolate, known for its health benefits, contains harmful levels of lead and cadmium.
- The study, conducted by Consumer Labs, did not name the products or manufacturers.
- Healthy Babies Bright Futures highlighted that these metals were found in amounts similar to the most contaminated foods tested by the FDA.
- People who eat small amounts of chocolate occasionally are at lower risk, but the risk is higher for children, pregnant women, and regular consumers.
The National Confectioners Association claims chocolate is safe and prioritizes food safety. Despite these assurances, experts advise being mindful of chocolate consumption, especially for vulnerable groups.
