Erythrosine is a cherry-pink synthetic dye used in food colouring. It is the second least common dye used in the US, but is used heavily in Europe where the alternative red, Allura Red AC, is banned.

Health considerations

Erythrosine approval is based on animal studies which have shown no negative effects with long-term use. However, erythrosine is associated with negative reactions in asthmatic patients. It may interfere with chemicals in the brain to lead to hyperactivity in children and may interact with white blood cells. Furthermore, studies in which high doses were given to animals have shown it to interfere with liver function, affect response to pain, and lead to changes in body weight.

Keep in mind

The FDA has a partial ban on erythrosine due to high doses being associated with cancer in rats; there have been calls for complete bans.
