I have no idea how these things work, but what struck me is the "restrictive" tone in the EU ("We couldn't find an adequate study proving or disproving, therefore we assume it's dangerous until proven otherwise") vs. what I view as a "permissive" view in the US ("We couldn't find an adequate study proving or disproving, therefore we assume it's safe until proven otherwise").
When it comes to things I put in my body, I would personally prefer the EU approach.
