US Health and Human Services Secretary Robert F. Kennedy Jr. has launched a campaign to address the growing health crisis linked to ultra-processed foods. Central to his strategy is dismantling the FDA’s GRAS (“generally recognized as safe”) program, which critics argue has enabled the food industry to fast-track chemical additives without rigorous oversight. Kennedy Jr. claims these foods are fueling chronic conditions like obesity, diabetes, and autoimmune disorders, particularly among children.
The GRAS Program: A Decades-Long Controversy
The GRAS designation allows food manufacturers to self-certify chemicals and additives as safe without FDA approval. A 2022 analysis cited by CNN revealed that 99% of new chemicals in food or packaging since 2000 were approved by the industry itself. Kennedy Jr. argues this system prioritizes corporate interests over public health.
“These foods are poisoning our children,” he stated during Senate hearings, vowing to remove ultra-processed products from federal nutrition programs like SNAP. His pledge aligns with mounting evidence linking such foods to heart disease, dementia, and early mortality.
How Ultra-Processed Foods Are Classified
In 2009, Brazilian epidemiologist Carlos Monteiro introduced the NOVA classification system, categorizing foods by processing levels rather than nutrients. Ultra-processed foods sit at the top tier, defined by industrial formulations with additives, preservatives, and artificial flavors not replicable in home kitchens.
| NOVA Classification | Examples |
|---|---|
| Unprocessed/Minimally Processed | Fresh fruits, vegetables, eggs |
| Processed Culinary Ingredients | Oils, butter, sugar |
| Processed Foods | Canned beans, cheeses |
| Ultra-Processed Foods | Chips, sodas, frozen meals |
While some ultra-processed items like whole-grain bread or yogurt retain nutritional value, most are engineered for hyper-palatability. “They combine sugar, salt, and fat in ways that hijack our cravings,” explains Dr. Neena Prasad of Bloomberg Philanthropies.
Health Risks: Correlation vs. Causation
Studies consistently associate ultra-processed diets with adverse health outcomes, but causation remains debated. Kevin Hall, an NIH researcher, conducted a landmark 2019 study where participants consumed 500 more calories daily on ultra-processed diets, leading to weight gain. Conversely, unprocessed diets resulted in weight loss.
“The mechanisms aren’t fully understood,” Hall admits. His ongoing research aims to isolate factors like texture, additives, and marketing influence. Meanwhile, advocates urge immediate action. “We can’t wait for perfect evidence while children suffer,” Prasad argues, pushing for soda taxes and stricter marketing regulations.
Industry Pushback and Practical Challenges
Food manufacturers defend processing as essential for safety, affordability, and shelf life. With ultra-processed items comprising 70% of the US food supply, dietary shifts pose logistical hurdles. Aviva Musicus of the Center for Science in the Public Interest emphasizes incremental changes:
- Prioritize whole foods in federal nutrition programs.
- Limit added sugars and sodium.
- Avoid moralizing food choices.

Policy Reforms on the Horizon
Kennedy Jr.’s initiative follows former FDA Commissioner Robert Califf’s 2023 remarks calling ultra-processed foods “one of the most complex challenges.” Potential reforms include:
- Revising GRAS criteria to require FDA review.
- Banning ultra-processed foods from SNAP.
- Funding long-term studies on additives.
