The New US Food Safety Reality: A Guide to Mandatory GRAS Notification, the Ultra-Processed Food Definition, and the Future of Ingredient Oversight

The era of food manufacturers secretly deciding their own ingredients are safe is ending. Under a sweeping new FDA rule proposed in August 2026, companies must now formally notify the government when they use the 'Generally Recognized as Safe' (GRAS) designation. At the same time, federal agencies are officially defining 'ultra-processed foods' to target the industrial formulations that make up 60% of the American diet. For consumers, this means unprecedented transparency. For the food industry, it means a massive compliance overhaul.[1][2]

The regulatory shift targets a decades-old mechanism known as the GRAS loophole. Since 1958, the Federal Food, Drug, and Cosmetic Act has required premarket approval for food additives. However, it carved out an exception for substances that qualified experts generally recognize as safe. Over time, this evolved into a voluntary system where manufacturers could self-affirm an ingredient's safety without ever submitting their data to the FDA.[3][4]

The new proposed rule, amending 21 CFR parts 170 and 570, eliminates that voluntary pathway. Any person introducing a substance into interstate commerce under the GRAS provision must now notify the FDA of the basis for their conclusion. While it is not a premarket approval process—companies can still market the substance while the FDA evaluates the notice—it forces the data into the public domain and gives the agency the visibility needed for post-market oversight.[2][3]

To manage the transition, the FDA is offering a one-year window for streamlined submissions. Food substances that are already on the market under a self-affirmed GRAS determination can be reported through a simplified pathway. This prevents an immediate bottleneck while ensuring that legacy ingredients are finally cataloged in the FDA's public inventory.[1][2]

The rule does include seven specific exceptions to prevent redundant paperwork. For instance, manufacturers do not need to submit a new notification if the FDA has already issued a 'no questions' letter for the exact same substance and intended use. Similarly, substances already affirmed as GRAS by existing FDA regulations are exempt.[2]

This regulatory tightening is part of a broader federal push under the Make America Healthy Again (MAHA) agenda. Spearheaded by HHS Secretary Robert F. Kennedy Jr. and USDA Secretary Brooke L. Rollins, the initiative aims to aggressively combat diet-related chronic diseases and childhood obesity. Closing the GRAS loophole was a primary directive issued by HHS leadership earlier in the year.[1]

Parallel to the GRAS overhaul, HHS and the USDA have advanced a proposed consensus definition of 'ultra-processed foods' (UPFs) for federal nutrition policy and research. Currently under review by the Office of Management and Budget, this definition is expected to harmonize how the government studies and regulates the most heavily engineered products in the food supply.[1][2]

The federal UPF definition leans heavily on the NOVA classification system, a globally recognized framework that categorizes food by the extent and purpose of its industrial processing. Under NOVA, Group 4 encompasses ultra-processed foods: industrial formulations made from substances extracted from foods, often containing little to no whole culinary ingredients.[5]

These products typically rely on cosmetic additives—such as artificial flavors, colors, emulsifiers, and non-sugar sweeteners—designed to mimic the sensory qualities of whole foods or disguise undesirable textures. The goal of such processing is to create highly profitable, hyper-palatable, and shelf-stable products that frequently displace minimally processed foods in the diet.[5]

By officially defining UPFs, federal agencies are laying the groundwork for future dietary guidelines and public health interventions. With CDC data indicating that nearly 60% of the calories consumed by Americans—and an even higher percentage among children—come from ultra-processed sources, establishing a standardized definition is the critical first step toward targeted policy.[1]

The combined impact of mandatory GRAS notifications and a formal UPF definition places the food and beverage industry under intense scrutiny. Ingredients that have quietly populated ingredient lists for years, from novel emulsifiers to modified starches, will now require documented safety narratives submitted to federal regulators.[3][6]

The public comment period for the proposed GRAS rule remains open until December 9, 2026. If finalized as proposed, the rule will take effect 60 days after publication, with full compliance required 18 months later. For food manufacturers, the clock is already ticking to audit their supply chains, gather their safety data, and prepare for the new era of ingredient oversight.[2][3]
