Evidence and Regulatory Summary
Red Dye No. 3 is now the clearest regulatory precedent in the synthetic-dye conversation because federal action is no longer hypothetical. That makes it useful as a marker for where the broader dye phase-out conversation started to become concrete.
Diet Notes
Red Dye No. 3 is less about allergy-style diet rules and more about whether you want to avoid a controversial color additive in products that usually have simpler alternatives. Parents tend to care most because the ingredient often shows up in kid-targeted categories.
Shopper Guidance
Use Red Dye No. 3 as an aisle-level filter. If a candy, frosting, or drink still relies on it during a phase-out window, that product is already telling you where it sits on reformulation urgency.
