...and we wonder why kids are crazy.
Surely this would lead to higher craziness in older people — children generally prefer milk chocolate, which the article does not point to as a risk.
[Daily Mail, where America gets its news] Consumer Reports put out open letters to Hershey, Modelez International — which owns Cadbury — and Theo Chocolate and Trader Joe's on Monday, following the a report by the group in late 2022 which found high levels of lead and cadmium in the companies' dark chocolate products.

The watchdog highlighted that long-term exposure to the metals could result in nervous system problems, immune system suppression and kidney damage. Though there is no indication that any of the bars individually contain enough to cause harm

Last month, Consumer Reports said 23 of the 28 dark chocolate bars it tested included potentially harmful levels of lead, cadmium or both for people who eat more than one ounce of chocolate a day.

Cadmium is naturally in soil and is thought to get absorbed by cocoa plants during the harvesting process.

There currently is no national limit on lead and cadmium in chocolate bars set by the Food and Drug Administration (FDA).
