A curated list of high-quality apps, tools, food databases, diets, research, and communities for managing IBD (Crohn's & ulcerative colitis), IBS, and elimination diets.
Living with a chronic gut condition means making hundreds of food decisions a week with scattered, often contradictory information. This list collects the resources that are actually useful — evidence-based, well-maintained, and made by people who understand the day-to-day reality.
Inclusion is based on usefulness and credibility, not popularity or commercial relationships. Entries within each section are listed alphabetically. Suggestions are welcome.
Not medical advice. Diets and treatments for gut conditions are individual; work with a qualified clinician or dietitian before making changes.
