The aim of the study was to monitor the adherence to gluten-free diet of patients suffering from celiac disease within the context of their routine everyday diet regimen and to quantify their daily intake of gliadin on the basis of gliadin determination in their current daily food. The gluten-free diet was followed for 30 days.
The patients for the monitoring were both the adults and children and they were chosen by the cooperation with coeliac society. Prior to the monitoring the patients were given PE bottles and grip-seal PE bags for sampling their food, beverages, and possibly also the medicines and food supplements ingested each day.
Individual components of the daily menu, the producers or distributors of respective commercial foods (not strictly required in samples not suspected to contain gluten), and weight or volume of all consumed components of the menu were recorded using a standardized form.
