Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
Health effects / Other evidence
Laboratory attention tests showed a reliable but small-sample effect of food colors (6 studies, 154 children, 0.27, 95% CI 0.07 to 0.47); the authors judge it too small and too old to support clinical or policy recommendations.
Weak evidence: Only 68 children in FDA-color-only studies; the colors-only result is vulnerable to single-study removal.
