The Blue 1 File: The Dye That Stayed.
Blue 1 spent years banned across much of Europe, then quietly became legal there again. But the sharpest thing in its record isn't the ban — it's the FDA public health advisory, issued over serious reactions in hospital patients receiving tube feeding, where the dye was being used as a marker. Different route, different population, real harm. This file goes to the record: what that advisory was actually about, why it almost never gets mentioned in the arguments about blue candy, what happened to the European bans, and what the evidence says about eating it. Every claim is graded in a certainty ledger — established, probable, open, unsupported — and nothing gets promoted a grade to make a better headline. Where the evidence runs out, the ledger says so. It closes with a wallet card: what to look for on a package in ten seconds, no chemistry required. Not a scare, not a cleanse, not medical advice. The principle is on the cover and it cuts both ways — Approved ≠ Safe. Not Approved ≠ Unsafe. Instant PDF, built to read on a phone.
