Here’s What You Need to Know About Food Dyes – And Why They May Be Banned

May 01, 2025

They’re in your cereals, favorite candies, snacks and even medications. Any food that looks super bright? It’s probably because of artificial food dyes.

Artificial food dyes have long made foods more colorful and appealing. But growing concerns about their health effects — especially in children — have prompted a shift.

Now, some artificial food dyes are on their way out. Here’s what you need to know.

Why now?

In recent months, public pressure and growing scientific scrutiny have prompted companies and government agencies to reconsider the use of artificial dyes in foods.

California became the first state to ban four additives — including Red Dye No. 3 — starting in 2027. Earlier this year, the FDA also said it would work with manufacturers to remove Red Dye No. 3 from foods. And most recently, the Department of Human and Health Services has called for companies to phase out all petroleum-based dyes by the end of 2026.

“This is a positive step,” says Andrew Wong, MD, a primary care provider with Hartford HealthCare Medical Group. “There’s been a lot of research over the years raising concerns about artificial food dyes and how they might affect brain and body development, particularly in children.”

What’s the concern with artificial food dyes?

The biggest concern is how dyes like Red No. 3 may affect kids.

Some studies have linked certain artificial colors to hyperactivity and behavioral issues in children. Others have raised concerns about potential cancer risk in animals, which prompted California’s action.

“These dyes are synthetic chemicals that the body doesn’t need,” says Dr. Wong. “Minimizing exposure, especially in growing kids, makes good sense.”

How to avoid artificial food dyes.

Dr. Wong recommends checking ingredient labels. Artificial food dyes often show up as color and number combinations (like Yellow 5 or Blue 1).

“You might find them in candies, cereals, snacks and even medications,” he says. “If you can, opt for products that use natural coloring — things like beet juice, turmeric or paprika extract.”

Should I be worried if I’ve eaten foods with dyes?

Dr. Wong says there’s no need to panic.

“Having eaten foods with artificial dyes doesn’t mean you’ll get sick. But the growing awareness is a reminder to read labels and make informed choices,” he says.

The bottom line.

“We’re learning more all the time about what’s in our food and how it affects our health,” says Dr. Wong. “It’s smart to pay attention and make small changes where you can.”

Start by checking labels, choosing more whole foods, and being mindful of what’s in your grocery cart — especially when shopping for kids.
