Understanding Food Dyes in Chewing Gum
While chewing gum may seem like a simple treat, it often contains a complex list of ingredients, including various artificial colorings. These dyes are used to create bright, appealing colors for different flavors, from cherry red to strawberry pink. The most prevalent red dyes found in processed foods, including many gums, are Red Dye No. 3 and Red Dye No. 40. Both have distinct histories and regulatory statuses that are important for consumers to understand.
Historically, Red Dye No. 3, also known as erythrosine, was commonly used in bubble gums and candies to achieve a vibrant red color. However, the dye faced decades of scrutiny following animal studies in the 1980s that linked it to thyroid tumors in male rats. This ultimately led to the FDA's decision in January 2025 to revoke its authorization for use in food, with a grace period for manufacturers to comply. This is a significant step towards removing potentially harmful additives from the food supply, but it does not apply to all red dyes.
The Role of Red Dye No. 40
Today, Red Dye No. 40 (Allura Red AC) is the most widely used and is still a common ingredient in many chewing gums, as confirmed by label checks on popular brands like Trident and Big Red. It provides the bright red color seen in many fruit-flavored gums. Unlike Red Dye No. 3, the FDA continues to consider Red Dye No. 40 safe for consumption within approved limits.
However, this dye is not without controversy. Some research and advocates, including the Environmental Working Group (EWG), have raised concerns about its potential health effects, particularly hyperactivity in children. A 2021 review suggested consuming Red 40 could lead to changes in brain activity and behavior based on both animal and human studies, though more research is needed. This has prompted some states, like California, to introduce legislation to ban certain food dyes, including Red Dye No. 40, in public schools, pushing manufacturers toward cleaner formulas.
Reading Labels to Avoid Red Dyes
For those seeking to limit artificial additives in their diet, learning to decipher ingredient labels is the most effective strategy. Manufacturers are required to list all color additives, and for some, like Red Dye 3 (Erythrosine), specific naming is mandatory. For Red Dye 40, you will see it listed as "Red 40," "Red 40 Lake," or "Allura Red AC".
What to look for on gum labels:
- Explicit Dye Names: Check for any variation of "Red 40," "Red 40 Lake," or "Allura Red AC."
- General Terms: The less specific term "artificial colors" can sometimes include Red 40 or other dyes. It's best to avoid these if you want to eliminate artificial colors entirely.
- Natural Alternatives: Look for gums that use natural colorings from plant-based sources, often listed as "vegetable juice for color" or specific fruit extracts.
The Shift to Natural Alternatives
As consumer demand for healthier, less-processed foods grows, many companies are responding by reformulating their products to use natural alternatives for coloring. These options are often derived from fruits, vegetables, and other plant-based sources. For example, some brands use vegetable juice, fruit juice concentrates, or paprika oleoresin to achieve a red or pink hue.
Examples of Dye-Free Gum Brands
- Pur Gum: This brand specifically markets itself as a healthy, naturally sweetened, and aspartame-free option that contains no artificial colors.
- Simply Gum: Uses natural flavors and plant-based ingredients for coloring, such as vegetable juice and paprika.
- Glee Gum: Features natural ingredients and is free from artificial colors, flavors, and preservatives.
Examples of Gums That Historically or Currently Use Red Dye
- Big Red: Lists "Red 40 Lake" as an ingredient.
- Trident Bubblegum: Also lists "Red 40 Lake" in its ingredient list.
- Dubble Bubble: Previously included Red Dye 3 and has been subject to reformulations.
Comparison of Red Dye 40 and Red Dye 3
| Feature | Red Dye 40 (Allura Red AC) | Red Dye 3 (Erythrosine) |
|---|---|---|
| Current Status | Permitted by FDA (within limits) | Banned by FDA for food/ingested drugs (effective Jan 2027) |
| Source | Petroleum-based synthetic | Petroleum-based synthetic |
| Associated Concerns | Potential link to hyperactivity in some children; debated safety | Cancer in male lab rats; led to ban |
| Prevalence | Very common in US foods, including some gums | Historically common; now being phased out due to ban |
| Labeling | Labeled as "Red 40" or "Allura Red AC" | Previously labeled as "Red 3" or "Erythrosine" |
The Broader Context of Your Diet
For many, the question of whether gum has red dye is part of a larger, more conscious approach to nutrition. Opting for dye-free gums and other products aligns with a cleaner eating philosophy, focusing on whole, unprocessed ingredients. This can be beneficial not only for avoiding controversial additives but also for reducing overall intake of highly processed sugars and synthetic compounds.
By being vigilant about reading labels and choosing products with natural colorings, you take a proactive step toward controlling what you consume. This practice extends beyond gum to other candies, beverages, and snacks where artificial colors are common. Making these informed choices is a fundamental aspect of maintaining a mindful and healthier nutrition diet.

Conclusion
While the ban on Red Dye No. 3 is a positive step, artificial colorings like Red Dye No. 40 remain prevalent in many chewing gums and other processed foods. For consumers who prioritize a cleaner nutrition diet, the responsibility falls on them to read ingredient labels carefully and seek out brands that use natural alternatives. By staying informed about which dyes are in your food and understanding the associated health concerns, you can make smarter choices for yourself and your family. The trend toward natural ingredients provides ample options for enjoying gum without the concern of artificial red dyes.
