No, the FDA Did Not Ban Red Dye Number 40—Here's Why You're Confused
The confusion about whether the FDA banned Red Dye Number 40 stems largely from the agency's January 2025 decision to ban Red Dye Number 3. Red Dye 3 was banned after a review of data linked it to cancer in animals, leading the FDA to revoke its authorization for use in food, drinks, and ingested drugs. This action caused many to mistakenly believe that Red Dye 40 was also banned.
Red Dye 40, also known as Allura Red AC, is a different petroleum-based additive and remains on the FDA's list of approved color additives, though it is facing increased scrutiny. Concerns about synthetic food dyes, driven by health advocacy groups and consumer interest, are pressuring regulators to review safety guidelines. Red Dye 40 is commonly used in various products, including cereals, candy, beverages, and cosmetics.
The Health Concerns Surrounding Red Dye 40
Although not banned, Red Dye 40 has been linked to health concerns distinct from those associated with Red Dye 3. Research primarily focuses on neurobehavioral effects and digestive health.
- Neurobehavioral Effects: A main concern is a potential link between Red Dye 40 and hyperactivity, particularly in children. While the FDA previously found no definitive causal link, some evidence suggests certain children may be sensitive. A 2021 review suggested synthetic food dyes could contribute to behavioral issues in some children. {Link: Drugs.com https://www.drugs.com/medical-answers/red-dye-40-bad-you-3579805/}
- Digestive and Inflammatory Health: Studies are exploring Red Dye 40's impact on gut health. A 2023 animal study indicated continuous exposure harmed gut health and caused inflammation in mice, raising questions about long-term human consumption effects.
Comparing Red Dye 40 to Red Dye 3
| Aspect | Red Dye Number 40 (Allura Red AC) | Red Dye Number 3 (Erythrosine) |
|---|---|---|
| Current FDA Status (2025) | Approved, pending further safety reviews. | Banned as a food additive due to animal cancer link. |
| Primary Health Concerns | Linked to hyperactivity, allergic reactions, and potential gut inflammation. | Primary concern was link to thyroid cancer in animal studies. |
| Chemical Origin | Derived from petroleum. | Derived from petroleum. |
| Common Use | Very common in a vast array of processed foods, beverages, and cosmetics. | Historically used in maraschino cherries, toaster pastries, and specific candies. |
| Regulatory Action | Increased public and political pressure for reassessment. | Formal ban announced by the FDA in January 2025. |
What does the future hold for food dye regulations?
Food colorant regulation is changing due to new research and consumer demand. {Link: USA Today https://www.usatoday.com/story/news/health/2025/04/23/food-dyes-banned-phased-out-rfk-fda-hhs/83230760007/} Some states have enacted their own bans; California, for instance, will ban certain dyes including Red 40 from public school food by 2028. These varying regulations mean the availability of products with Red Dye 40 is likely to change. Food manufacturers are already exploring natural colorants like beet juice to adapt.
Conclusion
While the FDA has not banned Red Dye Number 40, the situation is dynamic. The confusion largely stems from the separate ban on Red Dye Number 3. Red Dye 40 faces potential future regulation due to health concerns. Consumers wishing to avoid synthetic dyes should check labels for 'FD&C Red No. 40' or 'Allura Red AC'. The food industry is moving towards natural alternatives in response to pressure. The future of Red Dye 40's use in the US is uncertain but likely to change significantly.
