SACRAMENTO, Calif. — Gov. Gavin Newsom signed first-in-the-nation legislation Saturday that would ban California public schools from serving food dyes that color Froot Loops, Flamin’ Hot Cheetos and other processed snacks.

The blue, green, yellow and red additives affected by the ban have been linked to hyperactivity and other behavioral problems, particularly in people suffering from attention deficit hyperactivity disorder or ADHD.

The signing of this agreement marks the second time in as many years that Newsom has endorsed dietary rules that the food industry opposes. Last year, he also signed a law banning the sale of food containing other additives.

“Our health is inextricably linked to the food we eat, but fresh, healthy food is not always available or affordable for families,” Newsom said in a statement. “Today we do not accept the status quo and make it possible for everyone, including school children, to have access to nutritious, delicious food without harmful and often addictive additives.”

According to the Los Angeles Times, the producers of at least one product banned from 2023 – Peeps – decided to change the formula rather than pull the marshmallow chicks from store shelves.

Stores will still be able to sell food containing dyes covered by the new law. However, Assemblyman Jesse Gabriel, who authored both additive laws, hopes this latest change will encourage more companies to edit their regulations.

“We think it’s unlikely that people would intend to produce one version of their product for the California market and another version for Kansas,” Gabriel, who has ADHD, told reporters last month and talked about how the additives affected him. “We believe that if this bill becomes law, it will have the added additional benefit of helping protect children across the United States.”

Industry lobbyists have questioned California Environmental Protection Agency reports that associate dyes with health effects and have even argued that the rules could limit fundraising opportunities for school sports teams that hold bake sales. They convinced lawmakers to remove the ban on titanium dioxide — which is banned in the European Union and contained in snacks including Skittles — from the bill before it reached Newsom’s desk.

The legislation had broad bipartisan support in the state Legislature and gained support after its scope was narrowed through amendments. However, industry resistance remained.

“Safe ingredients have been demonized to advance a political agenda,” John Hewitt of the Consumer Brands Association previously told POLITICO in a statement. “Passing this bill could cost schools and families money, limit choice and access, and create confusion for consumers.”

The act will enter into force on December 31, 2027.
