“May” is doing some heavy lifting here. This is probably Sunset Yellow again (and the large amounts of sugar in the non-diet version, there’s caffeine in it too isn’t there?). Sunset Yellow was “linked” (in a JHJ sort of way) to ADHD forever ago but nothing ever came of it AFAIK.
The UK, EU and USA all test this stuff independently, especially if there’s any sort of public concerns.
