Part 1: International and EU-wide sources
These sources apply to all GFC content regardless of which market it is written for. Anything sourced from this section is treated as authoritative without further confirmation.
Tier A: Regulatory and scientific authorities
The primary sources of truth for drug approvals, health claims, clinical guidelines, and nutrition science at the EU and international level.
European Medicines Agency (EMA) — drug approvals, safety updates, and assessment reports for medicines authorized for use in the European Union. Used for all GLP-1 medication facts (semaglutide, tirzepatide, liraglutide, oral semaglutide).
European Food Safety Authority (EFSA) — scientific opinions on food, nutrition, and health claims. The source of record for the chicory inulin health claim and all other Article 13.5 authorizations.
- Main site: efsa.europa.eu
- EFSA Journal (official Wiley mirror, fetchable when main site blocks): efsa.onlinelibrary.wiley.com
Note: EFSA's main site frequently blocks automated requests with 403 errors. The EFSA Journal is officially hosted on Wiley Online Library at the second URL. Both contain the same authoritative content; the Wiley mirror is the practical access point for fetching EFSA opinions.
EUR-Lex — official journal of the European Union. The source for Commission Regulations, including the regulations that authorize EFSA health claims.
World Health Organization (WHO) — global health guidance, including dietary fiber recommendations and obesity classifications.
Cochrane Library — systematic reviews of clinical evidence. Used for evidence synthesis on fiber, GLP-1 medications, and related health interventions.
Tier B: Medical and scientific publications
Peer-reviewed journals and reputable medical press used for clinical evidence, study reporting, and contextual coverage of regulatory developments. We start with a tight list and expand only when a specific need is documented.
Peer-reviewed journals:
- The Lancet (thelancet.com)
- The New England Journal of Medicine (nejm.org)
- BMJ (bmj.com)
