Our source hierarchy
We prefer the most direct, established source available for a claim:
- U.S. public-health and regulatory agencies such as CDC, HHS, USDA, NIH, FTC, and NIST;
- professional pediatric guidance from the American Academy of Pediatrics and HealthyChildren.org;
- peer-reviewed research for narrower questions, with limitations stated;
- ProudMe’s own Privacy Policy and documented product behavior for product-specific claims.
Direct links appear near important claims and again under “Sources and further reading.” We avoid copying a statistic from a secondary article when the primary or established source is available.
