A new federal push to eliminate synthetic food dyes highlights broader failures in U.S. food safety regulation and growing concerns about the health effects of thousands of additives in everyday products.
Julia Belluz writes for The New York Times.
In short:
- U.S. Health Secretary Robert F. Kennedy Jr. plans to ban nine synthetic, petroleum-based food dyes within 18 months, part of a broader critique of the nation's food chemical oversight.
- American food companies can self-certify additives as safe through a regulatory loophole known as GRAS, bypassing U.S. Food and Drug Administration review; roughly 1,000 chemicals remain unknown to federal regulators.
- Scientific research on food additives typically focuses on cancer and acute toxicity in isolation, ignoring potential long-term or combined effects on chronic diseases like obesity and diabetes.
Key quote:
“FDA is stuck on decades-old science and making decisions based on scientific principles that in many cases are irrelevant.”
— Maricel Maffini, researcher of GRAS regulations
Why this matters:
Americans eat more ultraprocessed food than nearly any other nation, and many of these products contain additives that regulators know little about. From artificial colors to preservatives, thousands of chemicals enter our diets daily without robust, independent safety reviews. While Europe requires a precautionary approach — proving safety before approval — the U.S. often allows companies to police themselves under GRAS.
This system emerged in a different era, when the biggest threat from food was bacterial contamination, not the slow-burn rise of chronic diseases like obesity, Type 2 diabetes and heart disease. Emerging science shows that even additives considered “safe” may affect how cells grow, influence metabolism, or alter behavior—risks that traditional toxicology tests might miss.
