Missing Context

What We Found

The 1958 law is real. The Food Additives Amendment of 1958 required FDA pre-market approval for new food additives but exempted substances "generally recognized as safe" (GRAS) by qualified experts.

Secretly declare" is mostly accurate. A company can conclude on its own that an ingredient is GRAS and use it without telling FDA; notification is voluntary under the 2016 GRAS final rule (21 CFR 170.205). GAO (2010) found FDA can't ensure the safety of GRAS uses it isn't told about. The legal standard (21 CFR 170.30) still requires expert consensus based on generally available, usually published evidence; what's missing is FDA review.

Over 1,000" is an estimate. A Pew-funded, peer-reviewed analysis (Neltner et al., 2011) estimated about 1,000 GRAS substances never reported to FDA, and Pew's reports repeated that figure. EWG (2026) says "more than 1,000" may be in U.S. food. Nobody, including FDA, knows the exact number.

Synthetic" overstates it. Many GRAS substances are natural, such as plant extracts, flavors, fibers, salt and vinegar. The photos are generic stock images, not evidence about specific products.
