Chocolate lovers, beware: A recent study has uncovered that many dark chocolates contain harmful levels of lead and cadmium, raising concerns about potential health risks.
Study Findings
Published in ‘Frontiers in Nutrition’, the study by George Washington University analyzed over 70 dark chocolate products from major retailers including Whole Foods and Amazon. It found that 43% of these chocolates contained lead levels exceeding safe limits, while 35% had higher than recommended levels of cadmium. This study spanned from 2014 to 2022.
What’s Causing the Contamination?
Heavy metals like cadmium and lead enter chocolate through cocoa beans. Cadmium comes from the soil, and lead can be introduced during various stages of cocoa processing. Even organic chocolates, which are often thought to be cleaner, showed higher levels of these metals compared to non-organic varieties. This might be due to less processing or sourcing cocoa from specific regions with higher metal levels.
Health Risks
The World Health Organization (WHO) warns that lead can severely affect the nervous system and is especially dangerous for children, potentially leading to cognitive impairments. Cadmium is classified as a carcinogen and can cause kidney damage and bone issues with chronic exposure.
What Should You Do?
While the presence of heavy metals in chocolate is concerning, experts suggest moderation rather than complete avoidance. Eating small amounts of dark chocolate occasionally is generally considered safe for healthy adults. The key is to avoid products with very high lead content and maintain a balanced diet.
Leigh Frame, co-author of the study, emphasized that while the metals are a concern, they should not deter people from enjoying chocolate in moderation. “It’s really not about avoiding them; it’s about ensuring you’re not consuming too much,” Frame told USA Today.
So, if you’re a fan of dark chocolate, enjoy it in moderation and choose products from reputable brands to minimize potential risks.
