California governor Gavin Newsom signed the California School Food Safety Act into law last month .

The act bans foods containing six synthetic food dyes from public schools starting in 2028 .

The same dyes banned in California are still approved by the U.S. Food and Drug Administration .

Despite limited evidence of a neurobehavioral connection, some children are probably more susceptible than others.

A growing body of scientific research and anecdotal evidence has pointed to a link between some synthetic food dyes and neurobehavioral issues in kids.

In 2021 , California ’s Office of Environmental Health Hazard Assessment released a report that would push the state to ban Blue 1 , Blue 2 , Green 3 , Red 40, Yellow 5 and Yellow 6 in public schools.

Some animals exposed to synthetic dyes can become hyperactive or exhibit signs of memory loss.
