RFK Jr. Accelerates FDA Phase-Out of All Synthetic Food Dyes
HHS Secretary Robert F. Kennedy Jr. confirmed an accelerated timeline to eliminate all nine petroleum-based synthetic food dyes from the American food supply by the end of 2026. The FDA is phasing out Green No. 3, Red No. 40, Yellow 5, Yellow No. 6, Blue No. 1, and Blue No. 2, while pulling authorization for Citrus Red No. 2 and Orange B within months.
By early 2026, nearly 40% of the packaged food supply has pledged near-term removal, and school foods are seeing the fastest transitions. At the state level, roughly 75 bills targeting food dyes were introduced across 37 states, with West Virginia banning Red 40, Yellow 5, and Yellow 6 outright.

Kennedy Directs FDA to Close the GRAS Loophole
Secretary Kennedy directed the FDA to explore rulemaking to eliminate the self-affirmed GRAS (Generally Recognized as Safe) pathway — a longstanding loophole that has allowed more than 1,000 food additives into the American food supply with minimal oversight. Under the current system, companies can perform their own safety assessments without FDA review.
The proposed rule would require submission of notices for all substances claimed to be GRAS, bringing transparency and federal oversight to an industry that has largely self-regulated for decades. The draft rule has been under review by the Office of Management and Budget since December 2025.

FDA Moves to Phase Out Fluoride Supplements for Children
Federal health officials announced a phaseout of ingestible fluoride supplements for children, including drops, lozenges, and tablets, citing potential safety risks. The FDA will ask manufacturers to voluntarily withdraw these products while conducting a scientific review expected by October 2026.
Separately, the EPA urged a federal appeals court to reverse a landmark 2024 decision ordering the agency to regulate fluoride in drinking water — not disputing that fluoride poses an "unreasonable risk" to children's health, but arguing that the judge overstepped judicial process. At least 16 states are now weighing new fluoride restrictions.

FDA 2026 Human Foods Program: Three Priority Areas
The FDA released its Human Foods Program 2026 Priority Deliverables, focusing on three areas:
- Food Chemical Safety — Reforming GRAS, reviewing synthetic dyes, and addressing ultra-processed food additives
- Reducing Chronic Disease Through Better Nutrition — Collaborating with USDA to develop a federal definition of ultra-processed foods (UPFs)
- Microbiological Food Safety — Strengthening pathogen prevention across the supply chain
Kennedy also elevated a top FDA Human Foods official to his HHS management team, signaling that food safety reform remains a central priority of the "Make America Healthy Again" agenda.

Research: Daily Multivitamins Slow Biological Aging
A major study published in Nature Medicine found that daily multivitamin supplementation over 2 years decreased biological aging as measured by epigenetic clocks. The research showed that nutrient supplementation can modify epigenetic clock-based measurements of biological age — a significant finding for the supplement field. Cocoa extract supplementation did not show the same effect.

Prebiotic Fiber Shows Promise for Knee Osteoarthritis
A clinical trial demonstrated that a daily prebiotic fiber supplement (inulin) significantly reduced pain and improved physical function in patients with knee osteoarthritis. Inulin is a natural dietary fiber found in chicory root and Jerusalem artichokes that supports beneficial gut bacteria — further evidence of the gut-joint connection.
Fecal Microbiota Transplant Enhances Cancer Immunotherapy
Three landmark clinical trials confirmed that fecal microbiota transplantation (FMT) is a promising approach to enhancing immunotherapy efficacy in advanced solid tumors. This research reinforces the critical role of the gut microbiome in immune function and cancer treatment response.
