Food Safety Guides

In-depth research and analysis on food ingredient safety, FDA regulations, and brand accountability, backed by data from 859,000+ products.

How do we source these guides?

Our guides draw on public data, the FDA Substances Added to Food (SAFFA) inventory, CSPI Chemical Cuisine ratings, US state additive-restriction records, and the Open Food Facts product database. Every figure is sourced. Statistics, ratings, and scores come directly from those datasets, referenced inline so each claim traces back to its origin.

The aim is plain language. We translate dense regulatory data into explanations a general reader can act on, and when methodologies differ between sources or change over time, we flag the variation where it appears. Our editorial process includes regular reviews to keep figures accurate and current.
