Health notes

FD&C Red #40 Aluminum Lake is an FDA-approved color additive for use in food. The FDA announced in April 2025 a plan to phase out petroleum-based synthetic dyes, including Red 40. JECFA has evaluated Red #40 and established an acceptable daily intake, and EFSA has also evaluated it. Some studies suggest a link between synthetic food colors, including Red #40, and hyperactivity in some children, though the evidence is mixed and not all studies have found a consistent link.
