What it is

Yellow 5, also known as Tartrazine, is a synthetic yellow food color. It is a petroleum-based dye, meaning it is made from chemicals derived from crude oil.

Why it's used

Manufacturers add Yellow 5 to foods to give them a bright yellow color. It is often found in candies, cakes, snack cakes, pickles, and beverages to enhance their visual appeal.

Health notes

Yellow 5 is an FDA-approved food additive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5. JECFA has evaluated Yellow 5 and set an acceptable daily intake. EFSA has also evaluated this additive. Some studies, including the Southampton study, have suggested a possible link between synthetic food colors, including Yellow 5, and hyperactivity in some children, though evidence remains mixed and not all studies have found consistent results.
