Bad news - a new study from Consumer Reports & As You Sow shows that most dark chocolate on the market has unsafe levels of heavy metals: https://www.consumerreports.org/health/food-safety/lead-and-cadmium-in-dark-chocolate-a8480295550/

Good news - I made a rough Observable Notebook to navigate some of the underlying data: https://observablehq.com/@jasper/toxins-in-dark-chocolate

Will be updating & cleaning this up more in the coming days, but wanted to get it out there sooner rather than later 👍
