Health notes

FD&C Red No. 40 is an FDA-approved food additive. Some studies have suggested a link between synthetic food dyes, including Red No. 40, and hyperactivity in some children, though evidence is mixed and more research is ongoing. JECFA has evaluated FD&C Red No. 40 and set an acceptable daily intake. EFSA has also evaluated it. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40.
