The goal of this clinical trial is to learn if an app designed for diet education can help patients with inflammatory bowel disease (IBD) learn about healthy eating.

The main question[s] it aims to answer are:

• Is the app easy to use?
• Is the app useful? Researchers will compare the diet app to see if it is better at teaching patients about a healthy diet than the standard information they may receive from their doctor.

Participants will be asked to use the app for one month and answer surveys to see how easy the app is to use and if it leads to healthier eating.

(Background): Inflammatory bowel disease (IBD), encompassing Crohn's disease and ulcerative colitis affects various segments of the gastrointestinal tract. Although this is a chronic illness, patients may experience periods of active inflammation and inactive disease or remission. At diagnosis, patients commonly enquire about what they should not be eating or avoiding. In the past, advice was limited to vague recommendations to "avoid the foods that bother participants" due to lack of research data to support a specific diet as beneficial.

The etiopathogenesis of IBD is thought to involves genetic predisposition, an altered composition and function of the intestinal microbiome, and a dysregulated immune. Diet has been shown to play a role in modulating the intestinal microbiome. There is now growing evidence to support the role of diet in in the management of IBD and recent guidelines have made more concrete recommendations for Mediterranean diet and avoidance of ultra-processed foods.

Although gastroenterologists may be aware and able to advice patients on the type of diet, few would have the expertise or time to provide specific details of the foods that are allowed or excluded in these diets. Not all patients will have access to a dietician and those who have access to a consultation will not have regular reinforcement of the concepts discussed.

The investigators therefore propose a digital solution to bridge the gap in care and allow for daily reinforcement of nutrition knowledge to help patients adhere to a healthy eating pattern. The MyIBDDiet app is designed to allow for tracking of food intake including preparation method, added fats and food processing with immediate messaging feedback on whether the food item should be consumed more often or less often. Symptom tracking will allow patients to correlate how they felt to their food intake. Additionally, further education and resources will be provided in the form of short videos or visual tools. These resources will be developed in response to user requests.

In this randomized pilot trial study, the investigators aim to conduct a clinical investigation to evaluate the effects of the the intervention of using the educational diet tracking app (MyIBDDiet).

(Purpose): The investigators aim to evaluate the MyIBDDiet app, designed to improve self-management of a healthy eating pattern.

(Hypothesis): It is hypothesized that diet plays a role in modulating the intestinal microbiome. A Western diet high in saturated fat, sugar and processed foods contributes to intestinal microbiome dysbiosis and has been implicated in the pathogenesis of IBD. Conversely, an anti-inflammatory pattern of eating (e.g., the Mediterranean diet) with concomitant reduction in processed foods has recently been cited by the American Gastroenterology Association as an adjunct to inactive states of IBD.

Majority (85.4%) of individuals living with IBD believe diet is implicated in disease relapse. A paucity of established dietary guidance has led patients with IBD to self-impose dietary restrictions, thus further increasing risk of malnutrition. Furthermore, while larger centers are more likely to be associated with dedicated nutrition professionals, most with IBD may be faced with navigating nutrition misinformation associated with random websites and the IBD community, itself.

(Justification): Mobile health applications (apps) providing self-managed, evidenced-based diet and lifestyle programs are emerging for the IBD population. While many IBD-related apps exist, some of the apps focus solely on tracking without providing education while others provide recipes or therapeutic diets that require coaching. Few focus on diet education or self-management. As such, the investigators aim to develop a nutrition app that delivers up-to-date, evidenced-based diet information in a format that follows principles of adult learning. Newly developed electronic resources and videos will provide education on an anti-inflammatory pattern of eating, fiber and the intestinal microbiome, food additives and emulsifiers and practical substitutions in a restaurant setting will be made available in the app. Our goal is to expand beyond surface learning (i.e. Videos/handouts) to try to achieve a deeper level of understanding by having patients categorize their food intake while tracking with immediate feedback on the rationale behind the recommendation to choose the item more or less often.

By integrating videos, tutorials, and patient entries, MyIBDDiet app combines clinical advice with patient independence, and empowerment.

(Objectives): The objectives include evaluating the usability and acceptability of the app in improving diet quality and diet knowledge.
