Restaurant practices
Cross-contact controls, ingredient verification, training, communication, documentation, monitoring and incident response.
GCSI Research
Translate celiac research into everyday food-service practice.
GCSI brings together researchers, people with celiac disease, restaurants and public organisations to test practical interventions in real dining environments.
Research purpose
Move from published findings to measurable implementation.
Important evidence about celiac disease, cross-contact, staff knowledge, restaurant communication and consumer experience does not automatically become routine practice. GCSI is designed as an implementation environment where research questions can be translated into assessment items, education, restaurant procedures and measurable change.
Research outputs should remain methodologically transparent, ethically reviewed where required and independent of commercial pressure.
Priority research areas
Questions that can improve real dining decisions.
The programme combines food-safety evidence, behavioural research, implementation science, human–computer interaction and responsible digital infrastructure.
Diner decision-making
How people choose restaurants, interpret evidence, ask questions, manage uncertainty and participate socially.
Education and behaviour change
Which learning formats improve knowledge, confidence, consistency and implementation among restaurant employees and managers.
Digital trust and UX
How restaurant evidence, uncertainty, status changes and community reports can be communicated clearly without implying guarantees.
Developing research programme
The Restaurant Gluten-Free Trust Index.
The initial research programme develops a systematic review-based framework for assessing celiac-relevant restaurant practices. The work identifies candidate dimensions, indicators, evidence levels and verification methods that can later be tested in food-service settings.
The framework is being treated as a research and decision-support instrument during development. Pilot work must examine clarity, feasibility, reliability, burden, unintended effects and whether the results support meaningful improvement.
Vienna pilot
Start locally, test carefully and revise before scaling.
The first implementation phase is intended to build evidence about how the model works in practice—not to present a finished international certification system.
1. Co-designRefine the assessment and communication model with diners, restaurant teams and subject experts.
2. BaselineDocument current restaurant practices, evidence availability, staff knowledge and implementation barriers.
3. InterventionIntroduce targeted education, procedures, templates and practical improvement actions.
4. ReassessmentMeasure change in knowledge, documentation, process consistency and public communication.
5. RevisionPublish limitations, revise the methodology and decide what is ready for broader testing.
Participation
Different stakeholders contribute in different ways.
Participation opportunities will state the purpose, eligibility, expected time, data use, privacy protections and whether formal ethics approval applies.
People with celiac disease
Surveys, interviews, usability studies, restaurant-choice research and co-design of evidence displays and reporting tools.
Restaurants and hospitality teams
Baseline assessment, implementation studies, staff education, workflow testing and structured feedback on feasibility.
Researchers and clinicians
Study design, measurement, statistical analysis, clinical interpretation, publication and independent methodological review.
Public and tourism organisations
City pilots, public-catering programmes, regional benchmarking and evaluation of inclusive food-service interventions.
Research integrity
Clear methods, ethical participation and publication independence.
- Research questions, variables, exclusions and analysis decisions should be documented.
- Participant recruitment and consent should be proportionate to the study and reviewed where required.
- Health-related and personally identifiable information should be minimised and protected.
- Commercial partners must not control scoring, analysis or publication conclusions.
- Negative, null and implementation findings should not be hidden when they are important to interpretation.
- Public outputs should distinguish research evidence, restaurant-provided information and community experience.
Planned outputs
Research should leave behind usable public value.
Peer-reviewed research
Methods, validation studies, implementation findings and evaluations suitable for academic scrutiny.
Practical tools
Assessment protocols, questionnaires, training materials, checklists, templates and evidence-display components.
Public-interest reporting
Transparent summaries, benchmarking, methodology updates and policy-relevant findings written for non-specialists.
Research collaboration
Bring expertise, participants, data or implementation sites.
GCSI is interested in collaboration with universities, celiac associations, clinicians, dietitians, food-safety and hospitality researchers, laboratories, restaurant organisations, municipalities and tourism bodies.
Research translated into practice
Evidence matters most when people can use it.
Every programme should connect a research question to a practical decision, an observable change or a clearer statement of what remains uncertain.
