Common questions about food additives

What’s on every ingredient page

  1. 01

    Four countries, side by side

    The US, the EU, the UK and Canada, shown together wherever we found the additive on their lists. A country we couldn't match is left out, not marked as banned.

  2. 02

    A source for every line

    Every finding links to the paper it came from, and every rule links to the regulator's own list.

  3. 03

    We don't tell you what to eat

    We give no scores and no rankings. Each page reports what the studies found and what the rules say.
