Banned E-Numbers — Additives Prohibited Somewhere in the World

These additives are legal in some countries and banned in others — evidence that food safety regulation involves judgement, not just data.

Titanium dioxide (E171): banned in EU food since 2022, still legal in US and UK. Amaranth (E123) and cyclamate (E952): banned in the US since the 1970s, still permitted in EU.
