Thanks for this context. I generally like CR, but this kind analysis leaves a lot to be desired. Without some solid reasons for making their “level of concern” 6x more stringent that medical guidance for children.
That said from a quick look at the article there are plenty of choices that have much lower levels of lead, and I think calling out a product that has 8 ug of your daily 12.5 ug lead limit in a single serving is valid. Especially when there are a fair number of products in the 1 ug range (ie those under 200% of the CR limit). I don’t have to buy some gold plated protein powder to avoid “unreasonably” high (even if not directly harmful) levels of lead.
