FDA Targets GRAS Loophole as GLP-1 Diets Reshape Grocery Spending

The FDA's push to close the GRAS loophole signals a massive regulatory shift for food manufacturers, arriving just as GLP-1 grocery spending habits and new tariffs fundamentally alter the market

Food and beverage leaders face a triple shock this week. Between mandatory safety reviews for self-affirmed ingredients, federal trade duties facing immediate legal challenges, and a rapidly expanding demographic of appetite-suppressing drug users, the industry must adapt to shifting ground rules on multiple fronts simultaneously.

Closing the GRAS Loophole and Defining UPFs

For decades, food makers relied on a voluntary system to self-affirm chemicals as Generally Recognized as Safe. That era is ending. The FDA proposed mandatory safety notifications for GRAS ingredients, dismantling a framework in place since 1997. According to Environmental Working Group data, 99% of food chemicals introduced since 2000 bypassed formal FDA petitions through this self-affirmation. The new rule mandates a 45-day pre-filing review, a 120-day public comment window, and a final FDA safety determination within 180 days. Acting Commissioner Kyle Diamantas announced the shift, a major policy priority for HHS Secretary RFK Jr.

Meanwhile, the agency sent its UPF definition to the White House Office of Management and Budget as a white paper rather than a binding rule. Congress is pushing ahead regardless. The Sanders bill (SB 5026) demands UPF warning labels, while the Blumenthal-Booker bill (SB 5166) requires official FDA definitions and bans artificial ingredients in “natural” products. California already enacted the nation’s first statutory UPF definition in 2025, forcing manufacturers to align portfolios ahead of federal mandates and creating a runway for compliance.

Section 301 Tariffs and Consumer Trust Deficits

Trade policy is adding severe pressure. The administration replaced court-struck IEEPA tariffs with Section 301 duties targeting 59 countries over forced labor concerns. The rates, ranging from 10 to 12.5%, affect 99.4% of U.S. imports. Twenty-five state attorneys general filed suit within days, calling the move a workaround for previously struck-down rules. Colorado AG Phil Weiser led the charge, and a Court of International Trade three-judge panel will hear arguments.

While the legal battle brews, consumer trust is already eroding. An Omnisend survey of 1,075 U.S. shoppers found 85% believe brands use inflation as an excuse to raise prices beyond actual cost increases. Fifty-six percent stopped buying from offending brands entirely. Only 15% accept rising ingredient costs as a valid reason for higher prices, and 65% pinpoint groceries as the primary place they notice shrinkflation. Manufacturers struggling to transparently explain tariff costs risk accelerating this loyalty damage.

GLP-1 Grocery Spending Reshapes the Aisles

Consumer habits are physically changing. Twenty-two percent of U.S. households now include at least one GLP-1 user, double the rate from October 2023. Numerator’s quarterly tracker, analyzing over 95,000 consumer responses, reveals these households spend 4% less at grocery stores but control $660 billion in aggregate consumer spending. Their carts look distinctly different: carb-centric staples like pasta and packaged bakery are out, replaced by protein, fiber, seafood, and functional nutrition.

Sixty-six percent of former GLP-1 users quit within six months, making the cohort largely transient. However, at 22% household penetration, even a temporary group is large enough to dent category volume. The shift matches strategic bets already placed by General Mills and Nestlé, who are heavily investing in protein claims, functional formats, and smaller portion sizes to capture this evolving appetite.

What Happens Next

Expect the GRAS loophole closure to bottleneck new FDA food additives timelines as manufacturers adjust to the 180-day review process. Brands should prepare for a patchwork of regulations, using California’s statutory UPF definition as a baseline for reformulation. On the trade front, the Section 301 tariffs will likely remain tied up in the Court of International Trade for months, leaving import costs in limbo. Food makers must refine their pricing communications immediately to win back the 56% of shoppers who have already abandoned brands over perceived price gouging. Finally, product roadmaps must pivot hard toward protein and functional nutrition to capture the $660 billion controlled by GLP-1 grocery spending households.
