For months, the U.S. Department of Health and Human Services (HHS), under the leadership of Secretary Robert F. Kennedy Jr., has grappled with a nutritional policy challenge that has become the centerpiece of the current administration’s health agenda: the regulation of ultra-processed foods (UPFs). While the Department initially committed to establishing a rigorous, standardized definition for these products by April—a move following a formal Request for Information (RFI) published in the Federal Register—the momentum has hit a bureaucratic wall. Secretary Kennedy recently signaled that the complexity of the food system might render a universal definition for policy purposes functionally impossible.
However, a new consensus from the scientific community suggests that the complexity may be an excuse rather than an obstacle. A panel convened by Healthy Eating Research (HER) has released a robust framework that proposes a clear, actionable definition for UPFs, effectively challenging the notion that the problem is too nuanced to govern.
I. The Chronology of a Regulatory Deadlock
The push to regulate ultra-processed foods began in earnest during the summer of 2025. On July 25, the federal government issued a formal solicitation for public and expert input, seeking to understand the role of industrial food processing in the American diet. The timeline was clear: a definition was to be codified by the spring of 2026.
As the deadline approached, the narrative shifted. In various public briefings, Secretary Kennedy and his deputies expressed skepticism, citing the vast array of food manufacturing techniques and the ambiguity of the term "ultra-processed" as it currently exists in academic literature (such as the NOVA classification system). By suggesting that the task might be "too complicated" to legislate, the administration faced immediate criticism from nutritionists and public health advocates who argued that the government was prioritizing industry convenience over consumer protection.
The recent report from Healthy Eating Research serves as a direct rebuttal to this hesitation. By providing a technical, binary, and replicable definition, the expert panel has effectively placed the ball back in the FDA’s court, proving that if the agency is willing to act, the tools are already on the table.
II. The Expert Framework: Defining the "Ultra" in Processed
The HER panel’s proposed definition is designed to be "policy-ready," meaning it is intended for use in labeling, tax legislation, and school lunch programs. The panel avoids vague descriptors, instead opting for a mechanical, ingredient-based approach. Under this new framework, a food product is classified as ultra-processed if it meets at least one of two primary criteria.
The Cosmetic Additive Criterion
The first pillar of the definition focuses on "cosmetic additives." These are substances added to food not for nutritional value, but to manipulate sensory properties—appearance, texture, mouthfeel, and flavor. The panel identified a specific list that includes natural and artificial flavors, emulsifiers, non-sugar sweeteners, synthetic colors, thickeners, bulking agents, and anti-foaming agents. These additives are classified by the FDA or Codex Alimentarius as technical agents, and their presence is viewed by the panel as a hallmark of industrial restructuring.
The Non-Culinary Ingredient Criterion
The second pillar targets "non-culinary ingredients." These are substances rarely found in a home kitchen. This category includes high-fructose corn syrup, maltodextrin, protein isolates (such as soy or whey protein isolate), hydrogenated or interesterified oils, and mechanically separated meats. By including these, the panel is drawing a sharp line between "processed" foods—such as salted nuts or canned tomatoes—and "ultra-processed" foods, which are essentially industrial concoctions that rely on ingredients stripped of their original matrix.
III. Exclusions and Nuances: Protecting Whole Foods
Critics of the UPF movement often argue that the definition is too broad, potentially stigmatizing healthy foods that have undergone minor processing. The HER panel anticipated this concern by establishing clear "Exempt Ingredients" and "Exempt Foods."
The "Healthy" Claim Clause
Perhaps the most significant aspect of the proposal is the harmonization with existing FDA regulations. The panel recommends that any food product already meeting the FDA’s current, strict definition for "Healthy" claims be exempt from the UPF classification. This creates a bridge between existing federal policy and the new proposal, ensuring that products that are nutrient-dense—even if they have undergone basic processing—are not unfairly penalized.
This ensures that items like plain yogurt, whole-grain breads, or frozen vegetables (which may undergo basic blanching) remain unburdened by the stigma of being "ultra-processed," provided they do not contain the specific list of cosmetic or non-culinary additives mentioned earlier.
IV. Supporting Data: Why the Distinction Matters
The urgency behind this definition is rooted in a mountain of epidemiological data. Over the past decade, studies have consistently linked high consumption of ultra-processed foods to a range of chronic diseases, including Type 2 diabetes, cardiovascular disease, and obesity.
According to data from the National Health and Nutrition Examination Survey (NHANES), ultra-processed foods account for more than 60% of the average American’s caloric intake. The problem is not merely "calories in, calories out"; the issue is the "food matrix." When whole foods are pulverized, chemically extracted, and reconstituted, the body’s metabolic response changes. Fiber is lost, and the physical structure of the food is destroyed, leading to rapid spikes in blood glucose and a lack of satiety that often leads to overconsumption.
The HER panel’s definition allows researchers and policymakers to move beyond correlation and toward specific, actionable metrics. If a policy is implemented to reduce UPF intake in school districts, administrators now have a concrete checklist to determine which foods should be removed from vending machines and cafeteria lines.
V. Official Responses and Industry Pushback
The response from the food industry has been guarded. Trade groups, including the Grocery Manufacturers Association, have long argued that "ultra-processed" is a pejorative term that ignores the benefits of food technology in ensuring food safety, shelf stability, and affordability. They maintain that industrial processing is essential to feed a population of 330 million people.
Inside the FDA, the response has been quieter, yet equally significant. While the administration has not officially endorsed the HER report, sources within the agency suggest that the proposal is being reviewed by the Center for Food Safety and Applied Nutrition (CFSAN). The challenge for the FDA is not just scientific, but legal. Any definition adopted by the agency must survive rigorous scrutiny under the Administrative Procedure Act, meaning it must be supported by a comprehensive administrative record.
The HER panel’s report provides exactly that: a roadmap for the administrative record that the FDA previously claimed was missing.
VI. Implications for Future Public Policy
The adoption of this definition would be a watershed moment for American public health. It would open the door to a variety of policy interventions that were previously considered "too vague" to implement:
- Front-of-Package Labeling: Similar to warning labels in countries like Chile or Mexico, the FDA could mandate that products meeting the UPF definition carry a clear, standardized warning.
- Taxation and Subsidies: Fiscal policies, such as an excise tax on UPFs, could be used to subsidize the purchase of fresh, minimally processed produce, effectively leveling the playing field for lower-income households who currently find UPFs to be the most affordable calories.
- Institutional Procurement: Federal guidelines for the National School Lunch Program and the Supplemental Nutrition Assistance Program (SNAP) could be updated to phase out ultra-processed items, fundamentally shifting the demand side of the food economy.
VII. Conclusion: A Call to Action
Secretary Kennedy’s hesitation regarding the complexity of defining ultra-processed foods appears, in light of the Healthy Eating Research report, to be a choice rather than a necessity. The experts have done the heavy lifting. They have separated the cosmetic from the nutritional and the industrial from the culinary.
The task now lies with the federal government to move beyond the bureaucratic inertia that has characterized the last nine months. The science is clear, the definition is codified, and the public health imperative has never been more urgent. The FDA has been handed a solution; it is now time to see if they have the political will to implement it. If the goal is a healthier American population, the path forward is no longer complicated—it is simply a matter of execution.
For the American consumer, the stakes are high. The ubiquity of ultra-processed foods is not just a nutritional challenge; it is a structural reality of the modern food environment. By defining these foods, the government can finally grant consumers the transparency they deserve, transforming the grocery aisle from a confusing maze of industrial additives into a place where health and accessibility can finally coexist. The clock is ticking, and with this new framework, the excuse of "complexity" has officially expired.
