Key Takeaways
- The FDA is phasing out synthetic, petroleum-based food dyes due to safety concerns.
- Major companies like Nestlé and Mars are transitioning to natural colorants.
- Research continues on the potential health impacts of synthetic dyes, particularly in relation to ADHD.
Phase-Out of Synthetic Food Dyes Announced
On April 22, 2025, the U.S. Department of Health and Human Services (HHS) and the Food and Drug Administration (FDA) revealed plans to phase out synthetic, petroleum-based dyes from food products over safety concerns, particularly regarding neurobehavioral and potential carcinogenic effects. As public scrutiny increases, many companies are making strides toward utilizing naturally derived colorants.
In June 2025, Nestlé announced its commitment to eliminate synthetic colors from all its products by the end of 2026. Similarly, Mars pledged to release a naturally colored version of its famous M&M’s, albeit without brown and blue variants, which are challenging to replicate without artificial additives.
Colorants have been a part of food preparation for centuries, evolving significantly since the introduction of synthetic dyes in the 18th century. Initially, these synthetic dyes often contained toxic substances and were sometimes used deceptively. Today, both synthetic and natural colorants are regulated by the FDA, which requires them to be proven safe prior to their approval for use.
Currently, six synthetic colors dominate the U.S. food market: FD&C Blue No. 1, FD&C Blue No. 2, FD&C Green No. 3, FD&C Red No. 40, FD&C Yellow No. 5, and FD&C Yellow No. 6. While more synthetic colorants are approved for use in the European Union, both regions maintain safety protocols for assessing food additives.
Concerns regarding the carcinogenic effects of synthetic dyes are inconclusive. Some studies on rodents have shown potential pro-oxidative effects related to high doses of food dyes, but definitive clinical evidence is lacking. The relationship between synthetic food dyes and attention deficit hyperactivity disorder (ADHD) has garnered significant attention but yields mixed findings. A 2012 meta-analysis noted some indications that synthetic dyes could exacerbate ADHD symptoms, although the studies reviewed included various additives.
While direct evidence of harm from synthetic dyes remains weak, the industry trend is shifting toward natural alternatives. Natural pigments, sourced from plants, animals, minerals, and microorganisms, are gaining popularity. Specifically, dyes derived from microorganisms are predicted to play a significant role in the future, as they offer stability and a broad color range without the drawbacks of synthetic variants. This transition marks a significant evolution in food coloring practices aimed at enhancing consumer safety and satisfaction.
