The GRAS food ingredient rule proposed Monday would require food companies to notify the Food and Drug Administration whenever they conclude on their own that an ingredient is safe for consumption, replacing a voluntary system that critics have targeted for years.

The change addresses one of the most persistent complaints in American food regulation. Whether it fixes the underlying problem is a different question, and the answer depends heavily on who you ask.

The Loophole in Question

Generally recognized as safe, shortened to GRAS, is a designation that allows ingredients to enter the food supply without formal FDA approval.

Under the existing framework, companies may reach that determination internally and notify the agency only if they choose to. Many do not. The result is that substances can appear in products sold nationwide without regulators ever learning they exist.

Food safety advocates have described this as a significant blind spot for decades.

What the Proposal Would Change

The rule would eliminate the voluntary structure and make notification mandatory. Companies determining that an ingredient qualifies as safe would be required to inform the FDA.

Health Secretary Robert F. Kennedy Jr., appearing alongside influencers aligned with the Make America Healthy Again movement, said the measure would give the agency better visibility into what is entering the food supply.

Officials framed the timing around consumption patterns, noting that ultra-processed foods now account for close to 60 percent of the American diet.

What It Would Not Change

The gap that critics have seized on is what happens after the FDA receives that notification.

The proposal does not specify what action the agency will take regarding ingredients it finds questionable. It does not establish premarket review, meaning products can still reach shelves before any regulatory examination occurs. And it does not address postmarket review of ingredients already circulating in the food supply.

Scott Faber, senior vice president of government affairs at the Environmental Working Group, put it bluntly, saying it was difficult to avoid concluding that the food industry had a good day.

His specific objections centered on enforcement. The proposal, he said, does not clarify how the new standard would be enforced or what follows if the FDA fails to meet review deadlines. Companies using previously unknown substances will have to disclose them, but disclosure does not translate into removal from food.

The Staffing Question

Marion Nestle, nutrition expert and professor emerita at New York University, raised a practical problem that no regulatory text can resolve.

She asked who would actually perform the work. Who reads the submissions. Which qualified scientists remain at the FDA to evaluate them, after substantial staff reductions and an inability to rehire.

A mandatory reporting requirement generates paperwork. Whether it generates oversight depends on having people capable of reviewing what arrives.

Constrained by Existing Law

There is a structural reason the proposal stops where it does.

Former FDA commissioner Scott Gottlieb wrote on X that the agency appeared to have gone as far as existing law permits without new congressional action to strengthen oversight of food ingredients.

That framing reshapes the criticism somewhat. If the statutory ceiling sits below what advocates want, the limitation belongs to Congress rather than to the agency drafting the rule.

The Ultra-Processed Food Definition

Kennedy made a second announcement Monday. The Health and Human Services and Agriculture departments have submitted the federal government’s first definition of ultra-processed foods for final review.

The definition itself was not released publicly.

That matters enormously. A federal definition would establish the foundation for labeling requirements, school nutrition standards, dietary guidance and potentially procurement rules. Its precise wording determines which products fall inside the category and which escape it.

Industry Response

Food manufacturers have actually pushed for federal action on GRAS, though their reasoning differs from that of safety advocates. Their concern is a patchwork of state-level ingredient rules, which they argue would raise food prices.

Americans for Ingredient Transparency, a coalition that includes the industry-backed Consumer Brands Association, said the proposal underscores the limits of current law and called on Congress to modernize GRAS this year with a single national approach to ingredient review and labeling.

On ultra-processed foods, the industry position is considerably more hostile. Manufacturers argue a federal definition would generate widespread consumer confusion and drive grocery costs higher.

Rhonda Bentz, executive vice president of public affairs at the Consumer Brands Association, said the group is confident the definition will not advance once the president understands what she described as disastrous consequences for his affordability agenda.

That statement is notable for where it aims. Rather than contesting the science, it appeals directly to political priorities.

What to Watch

Several threads will determine whether Monday’s announcement produces meaningful change.

The first is congressional action. Both industry and former regulators point to Congress as the only body able to authorize premarket review, and legislative appetite remains unproven.

The second is the definition’s contents. Until the ultra-processed food language is published, its practical reach cannot be assessed.

The third is capacity. A reporting mandate without reviewers produces a filing cabinet, not a safety system.

The fourth is enforcement design. Faber’s question about missed deadlines is not academic. Regulatory requirements without consequences for noncompliance tend to function as suggestions.

The Bottom Line

For the first time, companies would be required to tell regulators what they are putting in food. That is a real shift from a system built on voluntary disclosure.

What follows that notification remains largely undefined, and the people most focused on food safety are treating that silence as the most important part of the proposal.
