What it is
Red 40, also known as Allura Red AC, is a synthetic food coloring. It is produced from petroleum and is one of the most commonly used red dyes in the United States.
Why it's used
Manufacturers add Red 40 to give foods a vibrant red color. It is frequently found in candies, beverages, cereals, and snacks like popcorn and cookies.
Health notes
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. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated Red 40 and set an acceptable daily intake. The European Food Safety Authority (EFSA) has also evaluated it. Some studies have suggested a link between synthetic food dyes, including Red 40, and hyperactivity in some children, particularly those who are sensitive to them. However, the evidence is mixed, and regulatory bodies continue to review the data.
Allergen info
Red 40 is a synthetic chemical and is not considered a major allergen.
