CLINICAL AND REGULATORY IMPLICATIONS OF ARTIFICIAL FOOD DYES IN THE UNITED STATES: A REGULATORY SCIENCE AND RISK-GOVERNANCE REVIEW

Purpose: Artificial food dyes are widely used in the U.S. processed-food supply, with exposure concentrated in
pediatric diets. This review synthesizes clinical, toxicological, and regulatory evidence through a regulatoryscience lens, emphasizing governance gaps, risk communication, and the implications of current oversight for
child health protection.
Design/Methodology/Approach: A structured narrative review was conducted using peer-reviewed clinical
studies, toxicological assessments, exposure-context materials, and regulatory documentation from major
authorities. Evidence was organized across three domains: (i) neurobehavioral outcomes in children, (ii)
mechanistic plausibility (oxidative stress and inflammatory signaling), and (iii) regulatory decision frameworks,
including risk-management tools (acceptable daily intake, labeling, and post-market reassessment). Core dyes
discussed include Red 40 (Allura Red), Yellow 5 (Tartrazine), and Yellow 6 (Sunset Yellow).
Findings: The evidence base most consistently supports heterogeneity of response: a subset of children appears
more vulnerable to dye-associated neurobehavioral effects, particularly in real-world dietary contexts that
include multiple additives. Toxicological literature provides plausible pathways—such as oxidative stress and
inflammatory activation—that may help explain differential susceptibility. Regulatory practices show persistent
misalignment across jurisdictions, and current U.S. approaches may not fully reflect contemporary exposure
patterns or modern expectations for neurodevelopmental endpoint evaluation.
Practical Implications: From a risk-governance perspective, feasible, proportionate measures include updated
toxicological reassessments, exposure-informed revisions of benchmarks, clearer labeling as risk
communication, and stronger post-market monitoring—particularly for pediatric-oriented products.
Originality/Value: The review integrates multidisciplinary evidence into a decision-relevant synthesis,
translating clinical and toxicological findings into implementable regulatory-management considerations that
prioritize vulnerable populations while maintaining scientific neutrality.
