Surprising Foods That Contain Artificial Food Dyes
Bright colors aren't just in candy—discover the hidden synthetic dyes in everyday foods you thought were wholesome.
When imagining foods containing artificial dyes, most people think of brightly colored candies, soda, and children’s cereal. However, synthetic food dyes are increasingly prevalent in a wide range of everyday groceries—even in items you might presume to be healthy or naturally colored. Understanding where these synthetic colors lurk, their potential health effects, and how to identify them can help you make more informed choices at the supermarket.
Why Are Artificial Food Dyes Used?
Artificial food dyes are chemical compounds derived largely from petroleum and coal tar, used by manufacturers to enhance the visual appeal of foods. These dyes can make processed foods look fresher, mask color loss during manufacturing and storage, and even suggest flavors to consumers by providing recognizable hues linked to certain fruits and spices.
- Increased use since mid-20th century; dye consumption has risen fivefold since 1955.
- Dyes such as Red 40, Yellow 5, and Yellow 6 are the most commonly used in the United States.
- Key drivers include consumer preference for vibrant foods and manufacturers seeking consistency across batches.
Health Concerns Associated With Artificial Food Dyes
While food dyes are regulated and considered safe in small amounts by organizations like the FDA, growing evidence raises questions about their effects on health, particularly in children. Important risks and concerns include:
- Potential links to hyperactivity and neurobehavioral issues in children.
- Possible allergic reactions and skin sensitivity in some individuals (such as eczema flare-ups).
- Animal studies suggesting DNA damage and increased cancer risk, though data in humans remains inconclusive.
- Calls for increased transparency, monitoring, and further research to assess long-term effects.
Food Dyes: Not Just in Candy
While candies, sodas, and neon snacks are classic examples, studies have revealed that dyes are present in about one out of every five U.S. food and beverage products. Many ‘healthy-looking’ foods rely on synthetic colorants to maintain a fresh or appetizing appearance. It’s not only brightly colored foods—muted, beige, or pale hues can also indicate the presence of dyes.
Common Synthetic Food Dyes Used in the United States
| Dye Name | Color Produced | Common Food Examples |
|---|---|---|
| Red 40 (Allura Red) | Red, Pink | Yogurt, Jams, Applesauce, Instant Oatmeal |
| Yellow 5 (Tartrazine) | Yellow, Green in combination | Pickles, Wasabi Peas, Sauces |
| Yellow 6 (Sunset Yellow) | Orange, Peach | Jams, Yogurt, Marmalade |
| Blue 1 (Brilliant Blue) | Blue, Green when mixed | Wasabi Peas, Frosting, Bagels |
| Red 3 (Erythrosine) | Bright Red, Pink | Deli Meats, Smoked Salmon |
Surprising Everyday Foods That Often Contain Synthetic Dyes
Here are some categories and specific products where artificial dyes are likely to be found—even if you wouldn’t expect it:
1. Pickles
You might be drawn to the bright green of bread-and-butter pickles and assume their allure is natural. However, manufacturers often add Yellow 5 to compensate for the fading of cucumber’s natural color during processing and storage. This makes pickles look fresh and appealing even after months in brine.

2. Fruit-on-the-Bottom Yogurt
Many yogurts—particularly those with “fruit-on-the-bottom”—employ Red 40 or Yellow 6 to boost their berry, peach, or cherry tones. Even plant-based yogurts or those marketed as “natural” sometimes use colorants to create a perception of richness and freshness.
3. Wasabi-Flavored Peas
The punchy green of wasabi peas looks like it might come from real wasabi, but the color usually comes from a combination of synthetic dyes, such as Blue 1 and Yellow 5, to achieve a leafy, intense green. Sometimes, a touch of Red 40 is added to deepen the hue.
4. Flavored Applesauce
Parents may reach for strawberry-flavored applesauce as a wholesome snack, not realizing its pink tint often comes from Red 40. Naturally, applesauce is beige, so dyes are used to mimic the “flavor” and appeal to children.
5. Instant Oatmeal
Strawberry or maple-brown sugar flavored instant oatmeals are packaged with visual cues to their flavors. Dyes like Red 40 are added to provide a blush to the “fruit” or “maple” pieces that otherwise would look brown or pale.
6. Jams, Jellies, and Fruit Spreads
With processed fruit products, the color of real fruit can deteriorate during cooking or over time in storage. To maintain the familiar, vibrant reds and oranges, companies commonly add Red 40 for strawberry and raspberry spreads, or Yellow 6 for orange marmalades, peach, or apricot jams. This provides a consistent, appetizing look regardless of natural color loss.
7. Processed Meats and Smoked Fish
Unexpectedly, deli meats can be treated with Red 3 to deepen their rosy color, while some smoked salmon and salmon cream cheese also utilize dyes for a fresher, more uniform appearance.
8. Blueberry Bagels and Baked Goods
Even foods like blueberry bagels may not derive their rich color from real blueberries but from synthetic blues and reds mixed to give a more dramatic effect. Some hot dog buns and tortillas also use dyes.
9. Marshmallows and White Icing
It is easy to assume “white” means dye-free, but many marshmallows and vanilla icings contain food coloring to enhance their purity and shelf appeal. Vanilla ice cream is similarly affected in some mass-market brands.
10. Other Packaged and Processed Foods
- Apple slices, goldfish crackers, and granola bars: Processed snacks often contain subtle dyes to make components stand out or look more appealing.
- Carbonated beverages and soft drinks: Even “clear” or lightly tinted drinks may use dyes for flavor cues.
- Cereals and whole-wheat products: Dyes may be used even in brown or tan cereals, multigrain snacks, and pizza crusts to standardize the color batch to batch.
Why Are Synthetic Dyes Everywhere?
The wide distribution of artificial dyes in the modern food supply is the result of:
- Industry Practices: Consistency and visual appeal drive companies to use dyes, as vibrant or “true to flavor” colors encourage product recognition and perceived freshness.
- Consumer Psychology: Studies show that humans evolved to associate brighter foods with ripeness and nutritional value. This visual bias is now leveraged heavily by food marketers.
- Loose Regulation: In the U.S., nine synthetic dyes are legal, and labeling requirements don’t always make it obvious unless you closely inspect the ingredients.
A study in the Journal of the Academy of Nutrition and Dietetics revealed that food dyes are present in many products not usually associated with color enhancement, which surprised even nutrition experts.
Are There Natural Alternatives?
Growing awareness about the potential health effects of synthetic dyes—and the push for cleaner labeling—has fueled interest in natural colorants. These often derive from plant, mineral, or insect sources, including:
- Beet juice (red/pink)
- Spirulina (blue/green)
- Turmeric (yellow/gold)
- Paprika or annatto (orange, yellow)
- Carrot juice concentrate (orange)
Though natural dyes tend to be less stable and more prone to fading, many brands are moving toward using them, especially after consumer pressure and regulatory shifts in places like the European Union.
How to Spot and Avoid Artificial Dyes
To minimize your exposure to synthetic food colors, follow these practical steps:
- Read ingredient lists carefully: Look for names like Red 40, Yellow 5, Yellow 6, Blue 1, and so on.
- Shop at stores with clean-label policies: Retailers like Whole Foods and others often ban artificial colors from their store brands.
- Choose minimally processed and whole foods: Unprocessed fruits, vegetables, legumes, and grains rarely (if ever) contain added colors.
- Be wary of unexpected sources: Even white, beige, or subtly colored foods like marshmallows, bread, and pickles can contain dyes.
- Seek brands and products that use natural colors: More options are appearing as consumer demand shifts.
