Artificial Color: FD&C Red 40

FD&C Red 40, also known as Allura Red AC, is a synthetic color additive. It is a petroleum-based dye manufactured through chemical synthesis. Its primary purpose is to impart a red color to foods and beverages.

Manufacturers add FD&C Red 40 to give products a vibrant red appearance. It is commonly found in a wide range of processed foods, including candies, snacks, cookies, beverages, and desserts.

FD&C Red 40 is an FDA-approved color additive for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, Green 3, Citrus Red 2, and Orange B. Some studies suggest a link between synthetic food colors, including Red 40, and hyperactivity in some sensitive children, while other reviews find the evidence mixed or inconclusive. Both the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated Red 40 and set acceptable daily intakes.
