For people with celiac disease
Understand what each restaurant has documented, when information was reviewed and where uncertainty remains.
Global Celiac Safety Initiative
Evidence for safer gluten-free dining.
GCSI helps diners understand restaurant practices and helps food-service teams assess, improve and communicate their approach to celiac safety.
A place at every tableEvidence, practical action and community participation belong in the same experience.
Designed around real decisions
One platform, different roles, clearer next steps.
GCSI connects transparent restaurant evidence, practical learning, community participation and collaborative research without treating claims, lived experience and independent review as the same kind of evidence.
For food-service teams
Identify priority gaps, strengthen repeatable practices and communicate accurately without making unsupported safety claims.
For chefs and culinary teams
Share attributed recipes, make ingredient verification visible and help the community cook with greater confidence.
For researchers and institutions
Connect rigorous research with participants, restaurants and implementation environments where findings can inform practice.
Our mission
Translate evidence into practical change.
To reduce preventable gluten exposure and uncertainty in food service by translating celiac research into transparent restaurant assessments, practical education, community participation and collaborative research.
Evidence status
More informative than pass or fail.
Important conclusions should show the evidence level, assessment date, scope and known limitations. A single colour or score must never stand in for the explanation.
Not providedNo relevant evidence was available.
Self-declaredInformation was provided by the restaurant.
DocumentedWritten records or procedures were reviewed.
ObservedA relevant practice was observed during assessment.
TestedApplicable laboratory or knowledge-testing evidence was reviewed.
Restaurant assessment
What supports the gluten-free claim?
The developing GCSI Index examines staff knowledge, kitchen cross-contact controls, ingredient and supplier verification, communication, monitoring and consumer experience.
Every public profile should show what was assessed, what was not assessed, the methodology version, current limitations and the next reassessment date. Restaurants pay for assessment, education and platform services—not for a favourable score.
Interface principles
Scientific credibility with hospitality warmth.
Calm
Inform without alarming or minimising risk.
Human
Address people, not abstract users or risk categories.
Evidence-led
Show the basis, date, scope and limits of a conclusion—not only the conclusion itself.
Transparent
Make uncertainty, conflicts and version changes visible.
Empowering
Turn information into a useful decision or practical next action.
Accountable knowledge
Published guidance remains traceable and open to correction.
Readers see the newest accepted version, its references and publication record. Proposed updates remain private until an eligible reviewer checks the evidence, edits the content and records a decision.
Vienna pilot
Start locally. Test carefully. Improve before scaling.
The first phase will test the restaurant index, learning pathways, community participation and governance safeguards with documented methods, limitations and measurable improvement decisions.
