Red 40 isn’t allowed in foods in the U.K. or E.U. without labels warning it "may have an adverse effect on activity and attention in children." That’s after research commissioned by British food authorities in 2007 linked hyperactivity in children to mixtures of synthetic dyes. The FDA has never evaluated the science on the neurotoxic effects of Red 40.
In 2021, California’s Office of Environmental Health Hazard Assessment published its investigation finding the seven most widely used synthetic food dyes—Blue 1, Blue 2, Green 3, Red 3, Red 40, Yellow 5, and Yellow 6—can cause or exacerbate neurobehavioral problems in children.
TAKE ACTION: Tell the FDA to Ban Neurotoxic Food Dyes!
