Concerns Surrounding Red Dye 40
Red dye 40, also known as Allura Red AC, is a common artificial food coloring derived from petroleum. It has been linked to potential health risks, particularly in children.
Neurobehavioral Effects in Children
Studies suggest a link between artificial food dyes, including red dye 40, and adverse neurobehavioral effects in some children, such as increased hyperactivity and inattentiveness. Not all children are affected, but some may be particularly sensitive.
Allergic and Inflammatory Reactions
Red dye 40 may cause allergic reactions like hives or migraines in some individuals. Research in mice also suggests continuous exposure could lead to gut inflammation and alter the gut microbiome, raising questions about its long-term impact on human digestive health.
Carcinogenic Contaminants
The dye is known to contain trace amounts of cancer-causing substances like benzidine from the manufacturing process. While levels are low, long-term exposure is a concern.
The National Ban on Red Dye 3
FD&C Red No. 3 (Erythrosine) has been used in foods despite evidence of potential harm. Animal studies in the 1980s linked high doses to thyroid tumors in male rats. The FDA banned its use in cosmetics in 1990 but delayed action on food for decades. Following a California ban in 2023, the FDA announced a nationwide ban on red dye 3 in foods and ingested drugs, effective January 2025.
Understanding the Difference Between Red Dyes
Red dye 3 and red dye 40 have different primary concerns and regulatory statuses. Red dye 3 was banned due to its link to cancer in animal studies. Red dye 40 is primarily scrutinized for potential neurobehavioral and inflammatory effects and is not currently banned in the U.S., although a phase-out is planned.

Avoiding Artificial Red Dyes
Many choose to avoid artificial red dyes, especially for sensitive individuals, including children. To avoid artificial red dyes, steps include carefully reading ingredient labels for specific dye names, choosing natural alternatives, prioritizing whole foods, and cooking at home more often.
Conclusion: Navigating the Controversy
The science on artificial red dyes highlights proven risks and ongoing research. While red dye 3 is banned, concerns remain about red dye 40 and its effects. Consumers should be informed about potential health implications, especially for children. Reading labels and choosing whole, naturally-colored foods can help reduce exposure.

Natural Coloring Options
Natural alternatives for vibrant colors include beet juice (red), strawberry puree (pink), berry extracts (purple/blue), and turmeric or paprika (orange/yellow). Carmine is another red option derived from insects.
What to Look For on Labels
Look for "FD&C Red No. 40," "FD&C Red No. 3," "Red 40," Allura Red AC (E129), or Erythrosine (E127). Natural colorants are often listed by their source, like "colored with beet juice."
The Ultra-Processed Food Connection
Artificial dyes are often in ultra-processed foods, which lack nutritional value. Avoiding these dyes often means avoiding foods high in added sugars, unhealthy fats, and sodium.
Future of Artificial Dyes
The regulatory landscape is changing, with the FDA banning red dye 3 and planning to phase out other artificial color additives by late 2026. This is pushing the food industry towards natural colorants.
Long-Term Health Impact
Beyond short-term effects, concerns exist about the long-term impact of synthetic food dyes. Research suggests potential DNA damage and inflammation. The full extent of these effects over a lifetime needs more study.
Regulatory Differences
Regulatory approaches differ globally. The EU requires warning labels for red dye 40, a more cautious approach than the historical U.S. stance. However, recent FDA actions show a shift towards aligning with global standards.
Making a Healthier Choice
Concerns about red dye and other artificial colorants are growing due to links to behavioral issues, allergies, inflammation, and potential long-term risks. The ban on red dye 3 and the planned phase-out of other dyes indicate a move towards safer practices. Choosing whole foods and reading labels are key steps.
Final Thoughts on Food Dyes
Artificial food colorings offer no nutritional benefit. Evidence of potential health risks strengthens the case for reducing reliance on these additives. Embracing the natural colors of food and choosing dye-free options supports a healthier diet overall.
Avoiding Dyes in Medications
Artificial colorants are also in many medications. Look for “dye-free” versions or check the inactive ingredients list. A pharmacist can help find dye-free options.
List of Products That Historically Contained Red Dye 3
- Maraschino Cherries
- Some Canned Fruit Cocktails
- Certain Candies, like Conversation Hearts and Candy Corn
- Chewable Vitamin Tablets
- Select Cough Syrups and Liquid Medications
- Certain Strawberry-flavored Drinks and Gelatins
What to Know About Red Dye 40 and ADHD
For parents concerned about ADHD, studies link red dye 40 to increased hyperactivity in sensitive children. Identifying sensitivities may involve a food diary and discussion with a healthcare provider.
