Red food coloring’s safety is a common concern, and at FOODS.EDU.VN, we understand why. This article will delve into the details of red food colorings, particularly Red No. 3 and Red No. 40, examining their potential health risks, regulatory status, and natural alternatives. We’ll empower you with the knowledge to make informed dietary choices, exploring topics like food additives, artificial dyes, and overall food safety.
1. What is Red Food Coloring and Why is it Used?
Red food coloring is a type of additive used to enhance the visual appeal of various food products. It comes in both natural and artificial forms, with each type possessing unique characteristics and safety profiles. Artificial red dyes like Red No. 3 (Erythrosine) and Red No. 40 (Allura Red AC) are synthetic compounds derived from petroleum. Natural red colorings, on the other hand, are sourced from plants, insects, or other natural materials.
These colorings are added to a wide range of products, including:
- Candies and Sweets: To create vibrant and attractive colors, especially in children’s treats.
- Beverages: To enhance the visual appeal of sodas, juices, and flavored milk drinks.
- Baked Goods: To give cakes, cookies, and pastries a more appealing appearance.
- Processed Foods: To standardize the color of products like sauces, jams, and jellies.
- Cosmetics and Pharmaceuticals: To add color to products like lipsticks, blushes, and medications.
The primary reason for using red food coloring is to make food more visually appealing. Color can significantly impact our perception of taste and desirability. A more vibrant and attractive color can make a product seem more appetizing and increase its marketability. However, concerns about the safety of artificial food colorings have led to increased scrutiny and a growing demand for natural alternatives.
2. What is Red Dye 3 and Why is it Controversial?
Red Dye 3, also known as Erythrosine, is a synthetic food coloring that has been used for decades to give a bright red or pink hue to various food products. Its official name is Red No. 3. It’s commonly found in candies, fruit cocktails, snack foods, Maraschino cherries, and strawberry-flavored milk. You can even find it in some medications such as cough syrups.

The controversy surrounding Red Dye 3 stems from several health concerns, primarily its potential carcinogenicity. In 1990, the FDA banned its use in cosmetics and topical medications due to evidence linking it to thyroid tumors in male rats. However, it remained legal for use in food products, leading to ongoing debate and calls for a complete ban.
Key Concerns about Red Dye 3:
- Cancer Risk: Studies on male rats showed that high doses of Red Dye 3 led to the development of thyroid tumors. While the FDA acknowledges that the mechanism of cancer development in rats may not directly translate to humans, the Delaney Clause of the Federal Food, Drug, and Cosmetic Act prohibits the use of any food additive that has been found to cause cancer in animals or humans.
- Hyperactivity in Children: Some research suggests a link between artificial food colorings, including Red Dye 3, and hyperactivity in children, particularly those with Attention Deficit Hyperactivity Disorder (ADHD). While the evidence is not conclusive, many parents and advocacy groups believe that eliminating artificial dyes from children’s diets can help manage ADHD symptoms.
Despite these concerns, Red Dye 3 has remained in use in many food products for years due to the FDA’s large mandate. The FDA has focused primarily on drugs and food safety with a specific eye on infectious diseases like Escherichia coli infection. It has been noted that there’s been a hole or a gap in food safety related to additives and environmental exposures and contaminants. However, the FDA, under the Biden administration, recently created a new food chemical safety office. This new office may be able to assess in a more holistic way multiple different exposures, from food additives to contaminants.
3. What is the Delaney Clause and How Does it Relate to Red Dye 3?
The Delaney Clause is a critical component of the United States’ Federal Food, Drug, and Cosmetic Act. Enacted in 1958, this clause prohibits the FDA from approving any food additive or color additive found to cause cancer in humans or animals, regardless of the dose. This “zero tolerance” policy reflects a precautionary approach to food safety, prioritizing the prevention of potential health risks over economic considerations.
The Delaney Clause states that no additive shall be deemed to be safe if it is found to induce cancer when ingested by man or animal, or if it is found, after tests which are appropriate for the evaluation of the safety of food additives, to induce cancer in man or animal.
The Delaney Clause played a significant role in the FDA’s decision to ban Red Dye 3 in cosmetics and topical medications in 1990. Studies had shown that Red Dye 3 caused thyroid tumors in male rats, triggering the clause’s prohibition.
Despite the ban in cosmetics, Red Dye 3 remained legal for use in food products for many years. This discrepancy raised concerns among consumer advocacy groups, who argued that the same safety standards should apply to all products intended for human consumption. The FDA maintained that the cancer mechanism observed in rats might not be directly applicable to humans, and the levels of Red Dye 3 in food were considered safe.
However, in early 2024, the FDA finally moved to revoke the authorization of Red Dye 3 in food and ingested drugs, citing the Delaney Clause as the primary reason. This decision reflects a renewed commitment to the precautionary principle and a growing recognition of the potential risks associated with artificial food colorings. Manufacturers of foods and ingested drugs have until January 15, 2027, and January 18, 2028, respectively, to remove the dye from their products.
The Delaney Clause serves as a vital safeguard for public health, ensuring that potentially carcinogenic substances are not added to our food supply. The recent action against Red Dye 3 underscores the clause’s continued relevance in protecting consumers from avoidable health risks.
4. What is Red Dye 40 and is it Safer than Red Dye 3?
Red Dye 40, also known as Allura Red AC, is another widely used synthetic food coloring. Unlike Red Dye 3, Red Dye 40 has not been definitively linked to cancer in animal studies. However, it has been associated with other health concerns, primarily hyperactivity in children.
While Red Dye 40 is generally considered safer than Red Dye 3 in terms of cancer risk, it is not without its potential drawbacks. Concerns about hyperactivity and behavioral changes in children have led to increased scrutiny and calls for stricter regulations.
Here’s a comparison table:
| Feature | Red Dye 3 (Erythrosine) | Red Dye 40 (Allura Red AC) |
|---|---|---|
| Primary Use | Food coloring, cosmetics (formerly) | Food coloring |
| Color | Bright red, pink | Red |
| Source | Synthetic | Synthetic |
| Cancer Risk | Linked to thyroid tumors in rats; banned in cosmetics by FDA | No definitive link to cancer in animal studies |
| Hyperactivity Risk | Possible link to hyperactivity in children | Possible link to hyperactivity in children |
| Regulatory Status | Banned in cosmetics; being phased out of food in the US | Approved for use in food by FDA and other regulatory bodies |
Potential Risks of Red Dye 40:
- Hyperactivity in Children: Numerous studies have explored the potential link between Red Dye 40 and hyperactivity in children, particularly those with ADHD. Some studies have shown that artificial food colorings, including Red Dye 40, can exacerbate ADHD symptoms in some children.

- Other Health Concerns: Some limited research suggests potential links between Red Dye 40 and other health issues, such as migraines and irritable bowel syndrome (IBS). However, more research is needed to confirm these associations.
While Red Dye 40 may not pose the same cancer risk as Red Dye 3, its potential impact on children’s behavior and overall health should not be ignored. Parents and individuals concerned about the potential risks of artificial food colorings may choose to limit their consumption of products containing Red Dye 40.
5. What Does the Science Say About Red Food Coloring and Hyperactivity in Children?
The link between artificial food colorings and hyperactivity in children, particularly those with ADHD, has been a subject of ongoing scientific debate. While the evidence is not conclusive, several studies suggest a potential association.
Key Research Findings:
- The Southampton Study (2007): Published in The Lancet, this study found that a mixture of artificial food colorings (including Red Dye 40) and sodium benzoate (a preservative) could increase hyperactivity in children aged three, as well as eight and nine years in the general population.
- Meta-Analysis (2012): A meta-analysis published in the Journal of the American Academy of Child and Adolescent Psychiatry reviewed multiple studies on artificial food colorings and hyperactivity. The analysis concluded that artificial food colorings could modestly increase hyperactivity in some children with ADHD.
- Additional Studies: Other studies have reported similar findings, suggesting that eliminating artificial food colorings from the diets of sensitive children can lead to improvements in behavior and attention.
Important Considerations:
- Individual Sensitivity: Not all children are affected by artificial food colorings. Some children may be more sensitive to these additives than others.
- Dosage: The amount of artificial food coloring consumed may play a role in the severity of the effects. Higher doses may be more likely to trigger hyperactivity in sensitive children.
- Other Factors: Hyperactivity and ADHD are complex conditions influenced by multiple factors, including genetics, environment, and diet. Artificial food colorings are likely just one piece of the puzzle.
The scientific evidence suggests a potential link between artificial food colorings, including red dyes, and hyperactivity in some children. While more research is needed to fully understand the nature and extent of this association, parents of children with ADHD may want to consider limiting their consumption of products containing these additives.
