Evidence: Moderate
Key takeaways
- Synthetic dyes like Red 40, Yellow 5 and Yellow 6 are common in kids’ snacks, cereals and drinks.
- Some studies link certain dyes to increased hyperactivity in some children; the American Academy of Pediatrics has raised concerns about food additives in children’s diets.
- The FDA’s plan to phase out petroleum-based dyes is voluntary, and the timeline has slipped, so reading labels still matters.
- Easy swaps exist for nearly every brightly colored snack.
Brightly colored snacks are everywhere in lunchboxes. If you want to cut back on synthetic food dyes, you don’t have to give up fun snacks. Here are easy, realistic dye-free snack swaps parents can make today.
Why parents are paying attention
A 2007 randomized trial in The Lancet found that mixtures of certain artificial colors (with a preservative) increased hyperactive behavior in some children from the general population. In 2018, the American Academy of Pediatrics issued a policy statement on food additives and child health, raising concerns about several additives, including artificial food colors. For the latest on U.S. policy, read our guide to the synthetic food dye phase-out.
Why we rated this “Moderate”: Controlled trials show some children are sensitive to certain dye mixtures, and pediatric experts have raised concerns. But effects vary between children and studies, so we rate this Moderate. How we rate evidence
How to spot dyes on the label
Look for names like Red 40, Yellow 5 (tartrazine), Yellow 6, Blue 1, Blue 2, Green 3 and Red 3, sometimes followed by “Lake.” Colors from sources like beet juice, turmeric, paprika, spirulina or annatto are typically listed by name. See how to read a food label.
