Blue 1 And Red 40

Blue 1 (also known as Brilliant Blue FCF) and Red 40 (also known as Allura Red AC) are synthetic color additives. They are petroleum-based dyes created through chemical synthesis.

These dyes are added to foods and beverages to give them a vibrant blue or red color, or to create other colors when mixed. They are commonly found in candies, cereals, soft drinks, baked goods, and dairy products like ice cream and yogurt.

Blue 1 and Red 40 are FDA-approved color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes both Red 40 and Blue 1. Concerns have been raised about a possible link between synthetic food dyes, including Red 40 and Blue 1, and hyperactivity in some children. However, scientific evidence on this topic is mixed, with some studies suggesting a link in sensitive individuals and others finding no consistent effect across the general population. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes.
