Dietary Intervention Using a Gluten-free App to Improve Tracking, Adherence, and Learning(DIGITAL) Study

myMedDiary is a HIPAA-compliant, researcher-configurable mobile and web-based application designed for real-time dietary, symptom and lifestyle data collection. It was utilized to collect dietary data in an IRB-approved study at Seattle Children's Hospital evaluating the dietary cost burden of gluten-free foods in pediatric patients with celiac disease (submitted for publication). The application enables participants to log meals using barcode scanning, keyword search, and manual entry, including recipe-level data. The backend system stores encrypted data securely in Microsoft Azure, and dietary entries are automatically converted to nutrient data using a standardized reference system. Researchers access de-identified participant data and analytics through a secure online dashboard. The system supports multicenter trials.

The MyMedDiary Application will provide feedback on potential gluten exposure when participants input dietary record information into the application.
