Full Study Name

My Nutritional Health App Testing (IRB no. 45933)


This study focuses on patients who are scheduled to see a dietician at a future appointment as part of routine clinical care. The purpose of the study is to evaluate the impact of the My Nutritional Health Application. This mobile app allows individuals to maintain a food diary and track gastrointestinal (GI) symptoms through the Food and Symptoms Tracker (FAST). Researchers aim to examine the relationship between participants’ GI symptoms and food. Once participants have downloaded the app, they will be prompted to answer questions related to food intake and mental or physical symptoms that may suggest food intolerance. A member of the study team will reach out to participants to assist with any technical difficulties or to answer questions.
