Common Sources of Artificial Red Dyes
Artificial red dyes, primarily Red Dye 40 (Allura Red AC) and Red Dye 3 (Erythrosine), are used extensively to enhance the visual appeal of processed foods and beverages. Manufacturers utilize them to create bright colors or to reinforce the perception of a specific flavor, such as cherry or strawberry. The presence of these dyes is widespread, often appearing in products not obviously red.
Where to Find Red Dye 40 (Allura Red AC)
As one of the most widely used synthetic food colorings in the United States, Red Dye 40 is a common ingredient in a huge variety of products.
- Snacks and Baked Goods: This includes items like Nacho Cheese Doritos, brightly-colored cereals (Froot Loops, Lucky Charms), and many fruit snacks. It's also found in pastries, cakes, and candy.
- Beverages: Look for it in sodas (Mountain Dew Code Red), sports drinks, powdered drink mixes, and some energy drinks.
- Dairy Products and Desserts: Flavored milks, yogurts, puddings, gelatins, and ice cream often contain Red Dye 40.
- Unsuspecting Items: The dye can also be found in certain barbecue sauces, packaged fruit cocktails, and even some varieties of pickled products and processed protein powders.
Foods Containing the Now-Banned Red Dye 3 (Erythrosine)
Following a California ban in 2023, the FDA announced a nationwide ban on Red Dye 3 for food use, which will take full effect in 2027. Many products that have traditionally used this dye are already being reformulated. Before the ban, however, Red Dye 3 was found in thousands of items.
- Candies: Gummy candies, popsicles, and confectionery decorations were common culprits. Iconic items like Brach's Candy Corn and Peeps historically included Red Dye 3.
- Drinks and Desserts: The dye was used to color strawberry-flavored drinks, pink frostings, and certain boxed cake mixes.
- Processed Foods: Some surprising items like certain vegetarian meat substitutes, meat jerkies, and processed sausages included Red Dye 3. Maraschino cherries, for which Red Dye 3 was a popular coloring agent, have been a long-standing source.
Comparison of Major Artificial Red Dyes

|---|---|---|
| Source | Petroleum-based synthetic dye | Petroleum-based synthetic dye |
| Regulatory Status (US) | FDA approved for use in foods, cosmetics, and drugs | FDA banned for food use starting in 2027 based on cancer findings in animals |
| Associated Health Concerns | Linked to hyperactivity in sensitive children, potential allergic reactions. Some animal studies suggest possible links to inflammation and neurobehavioral issues. | Linked to thyroid tumors in animal studies; prompted the FDA ban. Historically linked to behavioral issues in sensitive children. |
| Labeling | Labeled as "Red 40," "Red 40 Lake," or "Allura Red AC" | Labeled as "Red No. 3" or "FD&C Red No. 3" |
| Prevalence | Very common, used globally | Decreasingly common in the US due to state-level and upcoming federal bans |
Potential Health Concerns with Artificial Red Dyes
Concerns surrounding artificial red dyes go beyond simple aesthetics. While regulatory bodies like the FDA certify their safety for most people in approved amounts, scientific studies and consumer reports have highlighted potential adverse effects, especially for certain individuals.
Neurobehavioral Effects
Multiple studies have explored the link between artificial food dyes and hyperactivity in children. While the evidence is not conclusive for all children, research suggests that some sensitive children may experience worsened symptoms of ADHD, restlessness, and irritability after consuming these dyes. In Europe, products containing dyes like Red 40 carry a warning label stating the dye “may have an adverse effect on activity and attention in children”.
Cancer Risk
The most significant concern regarding Red Dye 3 came from animal studies that showed high doses could cause cancer. The FDA's 2027 ban on Red Dye 3 was a direct response to this evidence. While the link to cancer was specific to animals and the dose, it spurred consumer advocacy groups to push for stricter regulations on artificial additives. For other dyes, like Red 40, some animal studies suggest potential links to DNA damage, but the relevance to human health is still being researched.
Allergic Reactions and Inflammation
Though rare, some people may experience allergic reactions to artificial food dyes, with symptoms including hives and swelling. Additionally, animal research and preliminary human studies have explored potential links between Red Dye 40 consumption and gastrointestinal inflammation, such as colitis. These studies are part of an ongoing effort to understand the full impact of these synthetic additives.
How to Avoid Artificial Red Dyes in Your Diet
Reducing exposure to artificial red dyes requires proactive label reading and a shift toward less-processed foods. Here are some actionable steps you can take:
- Read Ingredient Labels Carefully: Always check the ingredient list for terms like "Red 40," "Allura Red AC," "Red 40 Lake," or "FD&C Red No. 40." While Red Dye 3 is being phased out, it is still crucial to check labels for "Red No. 3" or "Erythrosine".
- Choose Certified Organic Products: The USDA does not permit the use of artificial colors in foods with the certified organic label. This is one of the most reliable ways to avoid synthetic dyes.
- Reduce Packaged Food Consumption: Artificial dyes are most prevalent in ultra-processed, packaged foods marketed for their visual appeal. Focusing on whole, unprocessed foods like fresh fruits and vegetables is a great way to reduce your intake.
- Seek Natural Alternatives: Many companies are now using natural colorants derived from plants, such as beet juice, paprika, or annatto. Look for products that list these ingredients instead of synthetic dyes.
- Make Healthy Swaps: Instead of brightly colored, artificially flavored yogurt, stir fresh fruit into plain yogurt. For breakfast, opt for dye-free cereals or oatmeal with fresh fruit instead of colorful, sugary varieties.
- Drink More Water: Soda and other sweetened drinks are a major source of artificial dyes across all age groups. Switching to water or naturally flavored beverages is a simple change with a big impact.
Conclusion: Making Informed Food Choices
Understanding what popular foods have red dye in them is a crucial step towards making healthier dietary choices. While Red Dye 3 is now federally banned for food use and Red Dye 40 is generally considered safe by regulatory bodies in limited quantities, the documented links to hyperactivity in sensitive children and other potential health issues are valid reasons for concern. By being a savvy consumer, reading ingredient labels, choosing organic options, and favoring whole foods, you can significantly reduce your family's exposure to artificial food colorings and support a healthier diet.

How to Find Natural Red Color Alternatives
Many food manufacturers and home cooks alike are turning to natural alternatives to achieve a red hue without artificial dyes. These options provide vibrant color and are often sourced from whole foods.
