Brief Summary
The goal of the study is to test the efficacy of a dietary intervention in inducing clinical response and remission for patients with Crohn's disease in a randomized controlled trial. The intervention diet: DAIN has been adapted from the Inflammatory Bowel Disease Anti-Inflammatory Diet or IBD-AID™ taking into account the food availability and preferences of Puerto Ricans. DAIN also includes traditional foods commonly consumed in the typical Puerto Rican diet while maintaining the fundamental components of the IBD-AID™.

Outcome Measures
Primary Outcomes (1)
Improvement of health-related quality of life
Improvement of health-related quality of life (increase of the short Inflammatory Bowel Disease Questionnaire score (SIBDQ)). The SIBDQ scores range between 10 and 70 points. A slightly impaired quality of life is indicated by scores from 60 to 70 points, moderately impaired quality of life from 45 to 60 points, and severely impaired quality of life from 10 to 45 points.

Study Arms (2)
Arm1: Crohn's disease patients + DAIN
EXPERIMENTALParticipants will have 10 weeks of DAIN intervention (From week 1 to week 10)
Arm 2: Crohn's disease patients no intervention
NO INTERVENTIONParticipants will continue consuming their usual diet, with no intervention
Interventions
Participants in the experimental arm will have access to the newly created DAIN curriculum including menus, recipes, and recorded 'how to' recipes. Participants in the experimental arm will also have once-per-week dietary counseling with DAIN-trained nutritionists and monthly cooking classes with a DAIN-trained chef.

- Access Criteria
- Access to databases and associated software tools generated under the project will be available for educational, research and non-profit purposes. A portal will be created on the study website whereby anyone interested in collaborating or accessing to the data may submit a request form. Publication of data shall occur during the project, if appropriate, or at the end of the project, consistent with normal scientific practices. Research data, which documents, supports and validates research findings will be made available after the main findings from the final research data set have been accepted for publication. Such research data will be redacted to prevent the disclosure of personal identifiers.
All sequence data generated in this trial are understood to represent community resources and will be submitted to the appropriate public database. Specifically, data will be submitted to the NCBI (https://www.ncbi.nlm.nih.gov/), lncrnadb (http://www.lncrnadb.org/), and NONCODE (http://www.noncode.org/) databases as soon as sequencing data becomes available but not later than 2 years. Sequence data will also include information on quality values for each sequence as well as required fields for metagenomic data. The study will be in compliance with the NIH Genomic Data Sharing (GDS). Materials generated under the project will be disseminated in accordance with University/ Participating institutional and NIH policies.
