What it is
Red 40 (Allura Red AC) and Blue 1 (Brilliant Blue FCF) are synthetic food dyes. They are produced through chemical synthesis, typically derived from petroleum.
Why it's used
These dyes are added to foods to impart or enhance red and blue colors. They are commonly found in a wide range of processed foods, including candies, beverages, baked goods, cereals, and dairy products, to make them more visually appealing.
Health notes
Red 40 and Blue 1 are approved by the FDA as color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Red 40 and Blue 1. Concerns have been raised about a possible link between synthetic food dyes and hyperactivity in some children. Scientific evidence on this topic is mixed; some studies suggest a link, while others do not find a consistent connection. Regulatory bodies acknowledge the need for further research. JECFA has evaluated both Red 40 and Blue 1 and set acceptable daily intakes. EFSA has also evaluated these dyes and set acceptable daily intakes.
