The Scrutiny Behind Red Food Dyes
Concerns over artificial food colorings have been growing for decades, leading many consumers to question the ingredients in their favorite sweets. These concerns stem from numerous studies linking synthetic dyes to health issues, particularly in children. As a result, regulatory bodies and consumer advocacy groups have pushed for stricter rules, culminating in significant changes to the food supply.
The Fate of Red Dye No. 3
Red Dye No. 3, also known as Erythrosine, has been a source of contention for years. Derived from petroleum, it was primarily used to impart a vibrant, cherry-red color to foods. While banned from cosmetics in 1990 due to evidence suggesting a link to thyroid cancer in rats, it continued to be used in food products. Candies like some versions of Pez, Brach's Candy Corn, and even certain flavored milk and snacks historically contained this dye. Following public pressure and the FDA's acknowledgment of its carcinogenic potential in animals, the agency issued a ban in January 2025, with a grace period for manufacturers to reformulate products. This regulatory action is a significant victory for food safety advocates who argued that no cancer risk should be accepted for a purely cosmetic food additive.
The Controversy Surrounding Red Dye No. 40
Unlike Red Dye No. 3, Red Dye No. 40 (Allura Red AC) is still widely used in the United States, although it requires a warning label in the European Union regarding potential effects on activity and attention in children. Derived from petroleum, Red 40 is the most common food dye in the U.S. and can be found in a vast array of products, from Skittles and M&M's to snack cakes and beverages.
Potential side effects linked to Red 40, particularly in sensitive individuals and children, include:
- Hyperactivity and behavioral changes (e.g., ADHD symptoms)
- Allergic reactions (e.g., hives, itching, swelling)
- Migraines
- Gut inflammation and altered gut microbiome composition
While the FDA maintains that Red 40 is safe for the general population, the body of research and stricter regulations in other countries prompt many health-conscious consumers to avoid it. Some studies have also raised concerns about contaminants like benzene, a known carcinogen, found in Red 40.
Decoding Red Dye Ingredients: Artificial vs. Natural
Not all red colorants are created equal. Understanding the difference between artificial and natural sources is key for making informed decisions.
Synthetic Dyes
These are petroleum-derived colorants that offer stability and vibrant color at a low cost. They are designated with an “FD&C” prefix and a number, such as FD&C Red No. 40. These dyes are often used in highly processed foods and are not associated with any nutritional value.
Natural Dyes
Many food manufacturers are now turning to natural sources to achieve red coloring. Common options include:
- Carmine/Cochineal Extract (E120): This vibrant red pigment is derived from crushed female cochineal insects. It is often used to make products like yogurts, juices, and candy pink or red. While natural, it is an allergen for some and is not suitable for vegans or those who avoid insect-based products.
- Beetroot Red (E162): A deep red pigment extracted from red beets. This is a popular vegan-friendly alternative to carmine.
- Paprika Extract (E160c): Provides a reddish-orange hue and is extracted from paprika peppers.
- Lycopene (E160d): A bright red carotenoid found in tomatoes, which is often used as a colorant.
A comparison of common red colorants
| Feature | Red Dye 40 (Allura Red AC) | Red Dye 3 (Erythrosine) | Carmine / Cochineal Extract (E120) | Beetroot Red (E162) |
|---|---|---|---|---|
| Source | Petroleum | Petroleum | Crushed insects | Red beets |
| Status (USA) | FDA-approved, controversial | FDA-banned in food (as of 2025) | FDA-approved, natural | FDA-approved, natural |
| Health Concerns | Hyperactivity in children, allergies, inflammation | Linked to cancer in animal studies | Allergic reactions | Generally considered safe |
| Dietary Suitability | Not suitable for those avoiding synthetic dyes | Banned from food | Not vegan/vegetarian | Vegan/vegetarian-friendly |
Health-Conscious Candy Choices: What to Buy
With increased awareness and demand, many companies now offer candy made without artificial food dyes. When searching for healthier candy options, look for brands that explicitly state they use natural colorings or are dye-free.
- YumEarth: This brand specializes in organic and allergy-friendly candy, using fruit and vegetable juices for color.
- Unreal: Offers chocolate gems and bars colored with natural sources like beet juice.
- Black Forest Gummy Bears: Some varieties are made without artificial colors.
- Zolli Candy: Features a range of candies colored with fruit and vegetable juices.
- Simple Chocolate Bars: Most plain chocolate, like Hershey's milk chocolate bars, typically does not contain red dyes, but always check the label, especially for seasonal or colored varieties.
Conclusion: Making Informed Nutritional Decisions
The presence of artificial red dyes in candy, particularly the recently banned Red 3 and controversial Red 40, highlights the importance of scrutinizing food labels. While the FDA regulates these additives, research suggests potential links to adverse health effects, particularly for certain sensitive individuals and children. Thankfully, consumers can choose from a growing market of candy colored with natural ingredients like beetroot and carmine. By prioritizing a balanced diet rich in whole foods and reading ingredient labels carefully, you can make informed decisions that support your overall health and wellness.
