In a step toward safer food, the U.S. Food and Drug Administration (FDA) has approved three natural color additives to replace synthetic food dyes linked to health concerns. Announced on May 9, 2025, these new dyes—Galdieria extract blue, butterfly pea flower extract, and calcium phosphate—mark a shift toward natural ingredients in foods and beverages.
This move aligns with Health and Human Services (HHS) Secretary Robert F. Kennedy Jr.’s push to eliminate petroleum-based dyes from the U.S. food supply. Here’s what you need to know about the new approvals, why they took so long, and the history of synthetic dyes.
The FDA’s approval of these natural dyes comes after years of debate over the safety of synthetic food dyes. Pressure from health advocates, including RFK Jr., and growing public concern about chemical additives prompted the agency to act.
The FDA had previously stated that synthetic dyes, when used within approved limits, in regards to the Delaney Clause of the Federal Food, Drug, and Cosmetic Act, were safe.
However, recent studies linking dyes like Red 40 and Yellow 5 to hyperactivity, behavioral issues in children, and potential cancer risks in animals spurred action. The Biden administration initiated a phase-out of Red No. 3 in January 2025, and RFK Jr.’s “Make America Healthy Again” campaign accelerated the process.
“For too long, some food producers have been feeding Americans petroleum-based chemicals without their knowledge or consent,” RFK Jr. said during a press conference on April 22, 2025. “We’re removing these dyes and approving safe, natural alternatives to protect families.”
The FDA delayed approving natural alternatives until now due to industry resistance and regulatory hurdles. Synthetic dyes were cheaper and more stable, making them attractive to manufacturers.
So why wait so long? Apparently, because it costs less to add unnatural chemical based food dyes, powerful lobbiests persuaded politicians, and the FDA to continue using the dyes until recently.
Natural dyes, derived from plants and minerals, required extensive safety testing and faced pushback from food companies concerned about reformulation costs. Only recently, with mounting evidence and public demand, did the FDA fast-track approvals.
What Were the Previous Chemicals Made From?
Synthetic dyes like Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, and Green 3 are petroleum-based, derived from crude oil byproducts.
These petrochemicals, including compounds like Allura Red AC, were synthesized to create vibrant, long-lasting colors. Red No. 3, banned earlier, was linked to cancer in animal studies. These dyes are found in cereals, candies, beverages, and medications, raising concerns about their cumulative effects on health.
Why Were Synthetic Dyes Banned?
The FDA plans to phase out eight synthetic dyes by the end of 2026, citing health risks. Studies, including a systematic review, found correlations between synthetic dyes and neurobehavioral issues in some children, such as ADHD-like symptoms.
Animal studies suggested potential carcinogenic effects, though human evidence is less conclusive. RFK Jr. called these dyes “poison,” emphasizing their petroleum origins and lack of nutritional value.
“They should have been banned decades ago,” said FDA Commissioner Marty Makary. “Parents have observed these chemicals cause hyperactivity and aggressive behavior, which subsides when removed from diets.”
Why Weren’t They Banned Earlier?
Synthetic dyes continued due to economic and regulatory factors.
The food industry, a powerful lobby, argued that dyes were safe within limits, also important for making food look better and consumer appeal.
Reformulating products with natural dyes increases costs, potentially raising food prices.
In the 1958 Delaney Clause, the FDA was barred from approving additives linked to cancer, but older dyes were grandfathered in, and newer ones faced less scrutiny until recently. Europe’s stricter regulations, public pressure, and California’s 2023 ban on Red No. 3 exposed the U.S.’s lag.
The FDA expects food manufacturers to begin incorporating the new natural dyes by mid-2026, with synthetic dyes fully phased out by the end of 2026. The agency is providing regulatory flexibility to ease the transition, and many companies are voluntarily committing to the switch.
The approved dyes include two blues (Galdieria extract and butterfly pea flower extract) and a white (calcium phosphate), offering vibrant, plant-based options.
Who’s Involved in the Process?
RFK Jr., as HHS Secretary, and FDA Commissioner Marty Makary are leading the initiative.
The FDA is working with industry trade groups like the Consumer Brands Association to ensure compliance. California’s lawmakers, who pioneered state-level bans, inspired the federal push.
Internationally, the UK and EU have provided models for natural dye use, with experts like Devi Sridhar noting the U.S. is “way behind the curve.”
Several countries have restricted synthetic dyes for years:
- European Union: Since 2010, foods with certain dyes (e.g., Yellow 5, Red 40) must carry warnings about potential effects on children’s behavior. Most manufacturers switched to natural dyes like beetroot and turmeric.
- United Kingdom: Banned specific dyes in 1995 and encouraged natural alternatives by 2008.
- Canada: Regulates dyes strictly, banning unapproved additives and requiring labeling.
- Australia and New Zealand: Restrict several synthetic dyes, favoring natural options.
Why These Dyes Should Have Been Banned Long Ago
Health concerns about synthetic dyes date back decades. In the 1970s, studies suggested links to hyperactivity, yet the FDA prioritized industry interests.
Europe’s proactive bans and warning labels, starting in the 1990s, highlighted safer alternatives, but U.S. regulators lagged due to lobbying and a lack of political will.
The Delaney Clause should have triggered earlier action, but bureaucratic inertia and cost concerns delayed bans. Public health advocates argue that protecting children from potential risks should have taken precedence.
Additional Information
- Historical Context: The 1958 Delaney Clause was spurred by mid-20th-century “chemical anxiety” after books like Silent Spring exposed pesticide dangers, yet food dyes escaped strict scrutiny until now.
- Natural Dye Challenges: Natural dyes like butterfly pea flower extract can change color with pH levels, making them trickier to use but offering dynamic hues for innovative products.
- State Leadership: West Virginia’s August 2025 school ban on seven synthetic dyes is the most aggressive U.S. deadline, pushing the FDA to act nationally.
The food industry warns that reformulation could raise costs, potentially affecting low-income consumers.
Experts caution against assuming all natural dyes are inherently safer, as they still require rigorous testing.
This transition to natural dyes is a victory for health advocates but requires vigilance to ensure affordability and safety. As RFK Jr. stated, “We’re removing these dyes and approving safe, natural alternatives—to protect families.”
