The GRAS (Generally Recognized as Safe) loophole, established in 1958, was initially intended to exempt common, harmless substances like salt and vinegar from rigorous safety testing. However, it has since become a significant regulatory gap, allowing companies to self-certify chemicals as safe without FDA oversight or scientific evidence. This self-regulation has led to widespread use of untested or potentially harmful additives in the U.S. food supply. For instance, titanium dioxide, a whitening agent linked to chromosomal damage, is banned in the European Union but remains in over 1,900 U.S. products. Similarly, potassium bromate, a dough conditioner banned in multiple countries due to cancer risks, is still used in over 200 U.S. products.
New HHS Secretary Robert F. Kennedy Jr. argues that the GRAS system prioritizes corporate convenience over public health, leaving consumers exposed to potentially dangerous chemicals. He announced this week that HHS now seeks to end the FDA's GRAS rule.
Below is a list of 43 FDA-approved GRAS food additives and chemicals that have been the subject of concern regarding human health. Note that the safety of these substances is often debated, and regulatory agencies continue to monitor their use, but due to their ubiquitous nature in the American food supply, health concerns are legitimate in most circumstances.

Important Notes:
• The safety of these substances is often context-dependent, including the dose, frequency of consumption, and individual sensitivity.
• Many of these additives are considered safe in small amounts but may pose risks with excessive or long-term exposure.
• Consumers concerned about these additives should read food labels and opt for minimally processed foods when possible.
• Robert F. Kennedy Jr. is directing the FDA to take a closer look at these food additives and chemicals and is working with the food industry to improve the American food supply.
