The FDA plans to eliminate eight synthetic food dyes, including Red 40, Yellow 5, and Blue 1, from the U.S. food supply by the end of 2026. This move addresses health concerns linked to these dyes, such as hyperactivity and potential carcinogenic effects. The initiative encourages the transition to natural alternatives and includes collaboration with the NIH for further research on food additives’ impacts on children’s health.
Health Impacts of Synthetic Dyes
Several synthetic food dyes have been linked to health concerns in both human and animal studies. Citrus Red 2, used to color orange peels, has been connected to cancer in laboratory animals. Orange B, once used on sausage casings, is considered a potential carcinogen and is no longer manufactured in the U.S. Red Dye 40, one of the most common dyes found in candies and beverages, has been associated with hyperactivity in children. Yellow Dye 5, present in many snacks and cereals, may trigger allergic reactions and behavioral issues, while Yellow Dye 6, often used in baked goods, has shown potential links to tumor development in animal testing. Blue Dye 1, a staple in brightly colored confections, may cause allergic reactions and behavioral effects, and Blue Dye 2, frequently found in cereals and snacks, has been linked to brain tumors in animals. Lastly, Green Dye 3, sometimes used in canned vegetables, has shown possible associations with bladder tumors during animal studies.
Common Foods Containing Synthetic Dyes
Synthetic food dyes are widely present in popular American snacks and candies. Doritos, for example, contain Red 40and Yellow 6 to enhance their bold appearance. Cough drops, particularly certain red-colored varieties, often include artificial dyes such as Red 40, although dye-free alternatives are available on the market. Similarly, lollipops commonly rely on synthetic dyes to achieve their vibrant colors, but brands offering dye-free versions are increasingly accessible to health-conscious consumers.
International Standards on Food Dyes
While the United States is only now moving toward phasing out petroleum-based synthetic dyes, countries such as the United Kingdom and European Union (EU) have long taken stricter approaches. In the EU, foods containing dyes like Red 40 (Allura Red AC), Yellow 5 (Tartrazine), Yellow 6 (Sunset Yellow), Blue 1 (Brilliant Blue FCF), and Green 3 (Fast Green FCF) must carry a prominent warning label stating: “May have an adverse effect on activity and attention in children.” These labels were mandated after the 2007 Southampton Study found links between synthetic food colors and behavioral changes in children.
Additionally, several dyes are outright banned in the EU and U.K. due to toxicity or insufficient safety data. These include Red No. 2, Red No. 4, Orange 1, Orange 2, Green 1, Green 2, Violet 1, Butter Yellow, and Sudan 1, many of which were removed from U.S. products decades ago but still appear in imported goods or industrial applications elsewhere.
The U.S. Food and Drug Administration (FDA) has historically allowed wider use of these synthetic dyes under the condition of manufacturer compliance with concentration limits and usage guidelines. However, the new FDA-HHS initiative marks a shift toward aligning American food safety standards with more precautionary international norms—an overdue step, according to public health advocates.
Conclusion: A Natural Shift for Health and Industry
The FDA’s upcoming ban on petroleum-derived food dyes marks a critical turn toward cleaner, safer food labeling in the U.S. The move not only addresses long-standing health concerns—such as links to behavioral disorders, allergic reactions, and cancer—but also signals a cultural shift toward ingredient transparency. It pressures food manufacturers to innovate and reformulate, favoring plant-based and mineral-derived alternatives. For industry leaders like Sensient Technologies, this transition could translate to rising revenues and expanded influence in a market that increasingly values wellness, clean labels, and consumer trust. As consumers become more ingredient-aware, the demand for vibrant, safe, and naturally sourced food colorings is expected to grow exponentially.
