Could your favorite gummy bears, chips, or cookies soon look a little different? The FDA recently announced a sweeping new initiative to phase out several synthetic dyes from the U.S. food supply. But here’s the truth. Your favorite snacks aren’t disappearing—they’re just evolving.
When you open a bag of M&Ms or Skittles, you are looking at artificial dyes at work. Their bright reds, blues, and yellows come from synthetic dyes like Red 40 and Yellow 5. Some government officials and parents have had enough. And it’s not just candy. Our favorite salty, crunchy snacks like Cheetos, Doritos, and Takis also rely on dyes like Red 40, Yellow 6, and Blue 1 for that bold, eye-catching color.
So what’s really going on, and why now? Let’s look at how these dyes have been regulated—and why that’s starting to change.
A Note on Artificial Dyes and Synthetic Colors Safety and the GRAS List
Artificial dyes have been part of the FDA’s oversight for decades and were once considered “Generally Recognized as Safe” (GRAS). This means that they went through review and were approved for routine use. However, synthetic color additives follow a different regulatory path than GRAS substances. Indeed, each dye must get FDA approval before it can appear in food.
Recently, new research has emerged around long-term exposure and neurobehavioral effects. Additionally, consumer pressure and stricter European standards have triggered a renewed regulatory focus. As a result, dyes once seen as ordinary are now being questioned under a brighter spotlight.

FDA’s New Initiative on Artificial Dyes
In April 2025, the FDA and HHS announced plans to phase out six petroleum-based synthetic dyes—Green No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, and Blue No. 2—by the end of 2026. They’ve already revoked authorization for Red No. 3 under the Delaney Clause. Indeed, it must be removed from foods by 2027. At the same time, the FDA is fast-tracking approvals for natural color additives to make the transition smoother.
Major manufacturers like Kraft Heinz, Nestlé, and Conagra have already pledged to eliminate synthetic dyes—some by as early as mid‑2026.
Let’s take a look at each of the dyes in question.
Red No. 3 (Erythrosine)
Red No. 3 is a synthetic dye that produces a bright cherry-red color. It was once widely used in candies, baked goods, and certain snack foods. Originally considered safe as part of the FDA’s approved additives, it remained common in foods for decades. However, evidence from animal studies eventually linked Red No. 3 to thyroid tumors, which triggered renewed scrutiny.
Foods Most Affected
This dye appears in seasonal candies, cake decorations, popsicles, and some fruit-flavored baked goods. It has been especially popular in products designed to be visually appealing to children.
What the Science Says
Animal studies showed that high doses of Red No. 3 were associated with thyroid tumors. While the FDA banned its use in cosmetics in 1990, it remained legal in foods until recently. Under the Delaney Clause, which requires the FDA to prohibit additives shown to cause cancer in humans or animals, the agency has now revoked authorization for Red No. 3 in foods.
What Manufacturers Might Use Instead
Manufacturers reformulating products once colored with Red No. 3 often turn to natural coloring agents such as beet juice, pomegranate extract, or elderberry concentrate. Some also use carmine, though it is not suitable for vegetarians, vegans, or individuals with allergies.
1. Red No. 40 (Allura Red AC)
Red No. 40 is the most widely used red dye in the United States. It provides a bright, vivid shade that appears in a wide variety of packaged foods, from candy to cereals. The FDA originally approved it decades ago, placing it on the list of color additives generally recognized as safe. However, growing evidence and consumer concerns have placed it under intense scrutiny in recent years.
Foods Most Affected
This dye is most commonly found in brightly colored candies such as M&Ms and Skittles, fruit-flavored cereals, soft drinks, energy drinks, and frostings. It also appears in snack cakes, flavored yogurts, and gelatins. Because it is inexpensive and stable, manufacturers have relied heavily on Red No. 40 to make products more visually appealing.
What the Science Says
Studies have raised concerns about potential behavioral effects, especially in children. Some research suggests a link between Red No. 40 and hyperactivity or attention difficulties, although the evidence is mixed. In addition, there are reports of allergic reactions such as rashes, hives, or migraines in sensitive individuals. Although the FDA continues to allow Red No. 40 in food, under the Delaney Clause, the agency must reconsider approval if new evidence shows it causes cancer in humans or animals. Consumer advocates argue that this threshold is already being met.
What Manufacturers Might Use Instead
As the FDA phases out Red No. 40, manufacturers are expected to reformulate products using natural coloring agents. Common replacements include beet juice concentrate, hibiscus, or elderberry extract, all of which can provide similar red and pink hues. These natural sources are already in use in European products where synthetic dyes have long been restricted.
2. Yellow No. 5 (Tartrazine)
Yellow No. 5 is a synthetic dye that creates a bright, lemon-yellow shade. Approved decades ago, it is one of the most frequently used dyes in both sweet and savory products.
Foods Most Affected
Common in brightly colored cereals, candies, chips, and soft drinks such as Mountain Dew. It is also used in flavored drink mixes, sauces, and even some medications.
What the Science Says
Yellow No. 5 has been linked to hyperactivity and behavioral effects in children, with studies showing increased sensitivity in some populations. Additionally, individuals who are sensitive to aspirin may also experience allergic reactions to this dye. Although still permitted by the FDA, its safety is continually debated, and the Delaney Clause could require action if stronger cancer-related evidence emerges.
What Manufacturers Might Use Instead
Manufacturers are increasingly using turmeric, saffron, or annatto to produce yellow shades. These natural alternatives are already widely adopted in European products.

3. Yellow No. 6 (Sunset Yellow FCF)
Yellow No. 6 produces a golden-orange color often found in both sweet and savory foods. It has been a mainstay of processed snacks for decades.
Foods Most Affected
Found in chips such as Cheetos and Doritos, spicy snacks like Takis, orange sodas, pudding mixes, and baked goods.
What the Science Says
Animal studies have suggested a potential link to adrenal and kidney tumors, though findings are not conclusive. Like other synthetic dyes, Yellow No. 6 has been associated with hyperactivity in children. Despite its long-time approval, concerns about cumulative exposure are driving changes.
What Manufacturers Might Use Instead
Natural alternatives include paprika extract, annatto, and sweet potato powder. These ingredients can provide similar golden-orange tones, though they may be less intense than synthetic dyes.
4. Blue No. 1 (Brilliant Blue FCF)
Blue No. 1 provides a bright, electric-blue shade that stands out in beverages and sweets. It has been widely used since its approval decades ago.
Foods Most Affected
Common in sports drinks, ice pops, frostings, candy coatings, and colorful cereals.
What the Science Says
Research suggests Blue No. 1 may cause allergic reactions in sensitive individuals, and some studies are examining its potential effects on the nervous system. While not banned outright, it remains under close review as concerns grow over cumulative exposure.
What Manufacturers Might Use Instead
Manufacturers are shifting toward spirulina extract and butterfly pea flower to produce natural blue colors. These alternatives have already been approved for use in foods and beverages.
5. Blue No. 2 (Indigo Carmine)
Blue No. 2 creates darker blue tones and is often combined with other dyes to make purple shades.
Foods Most Affected
Found in grape-flavored sodas, candies, chewing gum, and some baked goods.
What the Science Says
Animal studies have suggested a possible link between Blue No. 2 and brain tumors, though findings are inconsistent. While regulators still allow its use, it remains a focus of ongoing safety reviews.
What Manufacturers Might Use Instead
Manufacturers reformulating foods may turn to purple sweet potato, red cabbage extract, or black currant juice to achieve similar blue and purple tones.
6. Green No. 3 (Fast Green FCF)
Green No. 3 is a less commonly used synthetic dye that produces a bright green color. Although not as widespread as reds or yellows, it has been a fixture in certain foods for decades.
Foods Most Affected
Mint candies, ice cream, sherbets, and some beverages.
What the Science Says
Animal studies have suggested possible links to bladder and testes tumors, though evidence remains weak. Its limited use has meant fewer studies compared to other dyes, but it is still included in the FDA’s phase-out plan.
What Manufacturers Might Use Instead
To create green hues, manufacturers often use spinach powder, matcha, or chlorophyll extracts. These natural pigments are already in use in European products and provide a safe, plant-based alternative.
What FDA Artificial Dye Bans Mean for Consumers
For American consumers, the FDA’s crackdown on artificial dyes does not mean favorite snacks are disappearing from shelves overnight. Instead, it signals that manufacturers will begin reformulating with natural alternatives. This process may take time, but the changes are already underway. For example, companies like Kraft Heinz and Nestlé have pledged to phase out synthetic dyes well before the FDA’s final deadlines.
A Shift from GRAS to Greater Scrutiny
Artificial dyes have been part of the American diet for decades under the FDA’s “generally recognized as safe” (GRAS) framework. Millions of people have consumed them without immediate effects. The change reflects evolving science, international pressure, and consumer demand for transparency—not an emergency food safety crisis.
What Consumers Can Expect in the Aisles
Shoppers may begin to notice small differences in color and presentation. Cereals may look less vibrant, chips may be a little less neon, and candies may take on more muted shades. At the same time, manufacturers are likely to turn this shift into a selling point with claims like “made with natural colors.”
Why Europe Looks Different
In Europe, the story looks very different. European regulators have long taken a precautionary approach. Some countries require warning labels for products with artificial dyes, while others have banned them altogether. As a result, manufacturers have already reformulated many products overseas using natural ingredients like beet juice, spirulina, and turmeric. The contrast highlights cultural differences: American consumers often value brand loyalty and flavor consistency, while European consumers push more strongly for clean-label foods.
What This Means for Families
For parents, especially those whose children are sensitive to dyes, the FDA’s action feels like an important step forward. Still, during this transition period, families should continue reading ingredient labels closely. Older versions of products may still be on shelves until the phase-out is complete.
Now, It’s Your Turn
The FDA’s decision to phase out synthetic dyes marks a turning point in the U.S. food system. While dyes like Red 40, Yellow 5, and Blue 1 have been part of our diets for decades, they are now being reconsidered in light of new evidence and international standards. The foods themselves aren’t disappearing, but they are evolving—and for many, that’s a welcome change.
Would you embrace snacks made with beet juice and turmeric instead of petroleum-based dyes, even if the colors look less bold?
Or do you prefer your Skittles, Cheetos, and cereals to stay just as they’ve always been?
