The proliferation of “natural” ingredients in our food supply often evokes a sense of reassurance, yet a recent investigation by the Environmental Working Group (EWG) reveals a troubling paradox: at least 111 substances of unknown safety have been added to foods, drinks, and supplements sold in the United States without any prior notification or review by the Food and Drug Administration. This isn’t a story about dangerous, explicitly banned chemicals; it’s about a legal, yet increasingly precarious, loophole in federal regulations that allows food companies to self-determine the safety of ingredients, a practice that fundamentally shifts the burden of proof from manufacturers to consumers – and potentially compromises public health. The concern isn’t necessarily that these substances are harmful, but that we simply don’t know if they are, and the current system actively prevents us from finding out.
The core of the issue lies within the “Generally Recognized as Safe,” or GRAS, exemption. Originally intended to streamline the approval process for ingredients with a long history of safe use, the GRAS loophole now allows companies to bypass the FDA’s pre-market review process by independently concluding that a new ingredient is safe, based on publicly available scientific evidence. While technically legal, this self-regulation has become, as Melanie Benesh, vice president for government affairs for the EWG, puts it, “more ‘generally recognized as secret’ instead of ‘generally recognized as safe.’” The EWG investigation identified 49 of these self-affirmed chemicals appearing in approximately 4,000 products listed in the USDA’s FoodData Central database, meaning consumers are unknowingly exposed to ingredients whose safety profiles remain unverified by the regulatory body designed to protect them.

The implications extend beyond simple transparency. Many of these ingredients are extracts – concentrated forms of substances derived from sources like grape skin, aloe vera, and mushrooms. Maricel Maffini, a biochemist and coauthor of the EWG investigation, explains that concentrating these natural compounds creates a “cocktail of substances” that haven’t been individually or collectively assessed for safety. Take green tea extract, found in over 900 products in the USDA database, ranging from granola bars to seafood. While green tea itself is associated with health benefits, highly concentrated extracts have been linked to liver damage, with at least 100 established cases reported. This highlights a critical distinction: the safety of a whole food doesn’t automatically translate to the safety of its isolated, concentrated components.
The situation is particularly concerning when considering the perception of “natural” equating to “safe.” Aloe vera, for example, appears in over 450 products, yet unpurified whole-leaf aloe vera extract has been linked to cancer and kidney failure, prompting the FDA to ban its use in laxatives. This disconnect between public perception and scientific reality underscores the need for rigorous, independent safety assessments. Mathilde Touvier, director of research at France’s National Institute of Health and Medical Research, emphasizes the ethical problem: “It is highly problematic that companies are allowed to self-determine that their own ingredients are ‘GRAS,’ given the obvious financial conflict of interest.” Decisions about food safety, she argues, should be made by public health authorities, not the companies profiting from the ingredients themselves.
Industry representatives acknowledge the need for reform, but frame the issue differently. Sarah Gallo, senior vice president of the Consumer Brands Association, stated that the CBA is part of a coalition advocating for “federal legislation establishing national uniformity for ingredient safety and disclosure.” While supporting GRAS reform, the CBA maintains that the US possesses “one of the safest and most highly regulated food systems in the world.” This assertion, however, is directly challenged by the EWG’s findings and the historical record. A 2014 report revealed that 56 companies relied on undisclosed GRAS determinations for 275 chemicals, and even when manufacturers do submit GRAS notifications to the FDA, the agency rejects or triggers withdrawal of one in five requests.
Recent events further illustrate the potential for harm. The 2022 recall of a frozen vegetable-based meat substitute, linked to hundreds of reports of gastrointestinal and liver illness, was traced back to tara flour – a substance not adequately characterized for human consumption. It took two years for the FDA to remove tara flour from the GRAS list, during which time consumers remained unknowingly at risk. This incident, as highlighted by Dr. Pieter Cohen of Harvard Medical School, demonstrates a fundamentally “broken” system that prioritizes industry self-regulation over proactive public health protection. The current administration has signaled intent to address the GRAS loophole, but progress has been slow, and the long-standing case of BHA – a possible human carcinogen still permitted in thousands of foods despite decades of concern – serves as a stark reminder of the FDA’s historical inertia.
The question now isn’t simply whether the GRAS loophole will be closed, but how effectively. Will reforms focus on strengthening FDA oversight and requiring mandatory pre-market notification for all new ingredients, or will they settle for a more incremental approach that relies on industry self-compliance? Consumers should be watching closely for the details of any proposed legislation and demanding greater transparency and independent verification of ingredient safety. More importantly, they should be aware that a “natural” label is no guarantee of safety, and that the burden of protecting public health ultimately rests on a regulatory system that, for too long, has allowed food companies to police themselves.
