Artificial Colors: Fd & C Red#40

FD&C Red No. 40, also known as Allura Red AC, is a synthetic food coloring. It is manufactured from petroleum and is one of the most commonly used food dyes in the United States.

Manufacturers add Red 40 to give foods and beverages a red or orange color. It is frequently found in candies, gelatin desserts, soft drinks, baked goods, and breakfast cereals.

Red 40 is an FDA-approved color additive for use in food, drugs, and cosmetics. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40. Some studies have suggested a link between synthetic food dyes and hyperactivity in some children, though the evidence is mixed and not all studies have found a consistent effect. JECFA has evaluated Red 40 and set an acceptable daily intake. EFSA has also evaluated this additive.
