The perception I'm aware of is that it is mixed in sensibility from early bans of carcinogenic while also including frustratingly absurd junk science bans and luddite paranoia over GMOs pushed by absurdly protectionist farmers who literally would riot over their neighbors one kilometer from the province border being given the right to use a name for identical food stuffs despite the climate and soil being identical - the whole division was literally political since ancient times.

The bit with dyes on kid focus issues for instance. That doesn't sound like a health effect - it sounds like kids being excited over bright colors as they are prone to be! It seems to fit so well with the suggestion bias of thinking kids were more hyperactive when they were given candy.
