Health notes
Yellow 5 is an FDA-approved food additive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5. JECFA has evaluated Yellow 5 and set an acceptable daily intake. EFSA has also evaluated this additive. Some studies, including the Southampton study, have suggested a possible link between synthetic food colors, including Yellow 5, and hyperactivity in some children, though evidence remains mixed and not all studies have found consistent results.
