How GRAS works
The Generally Recognized as Safe (GRAS) classification, established by Congress in 1958, allows food companies to bypass federal safety reviews for new ingredients.
This regulatory pathway enables manufacturers to independently verify the safety of their ingredients without direct Food and Drug Administration (FDA) oversight, provided industry experts consider them safe.
While originally intended for common ingredients like vinegar or baking soda, the pathway has expanded significantly.
The transparency gap
Because of the self-affirmation bypass, thousands of additives have entered the US food supply without formal public tracking or review by the FDA.
While European regulations limit legal food ingredients to approximately 400 substances, estimates for the US food supply range between 4,000 and 10,000 ingredients.
Many of these substances lack public data regarding their long-term health consequences.
