IBD research sources
Content note: Educational content aligned with publicly available patient materials from the Crohn's & Colitis Foundation and other major IBD education sources. IBDPal is not affiliated with or endorsed by the Foundation. Last reviewed June 2026. Not individual medical advice.
Educational use only. IBDPal does not provide medical advice, diagnosis, or treatment. Always consult your gastroenterologist or IBD care team for personal decisions.
Government public health pages, clinical guidance, and research registries for Crohn's disease and ulcerative colitis. IBDPal links to originals and summarizes in patient-friendly language. Not medical advice.
Reuse and licensing notes
Many U.S. government health pages are public information, but not every image, journal article, or third-party item on a federal site is reusable. IBDPal links to originals, summarizes in our own words, and notes source reuse guidance when available. Always check the publisher page before copying charts, images, PDFs, or licensed third-party material.
AGA Clinical Practice Update: Diet and Nutritional Therapies in IBD (2024)
AGA guidance on how gastroenterologists may discuss diet and nutritional therapies with IBD patients. Covers enteral nutrition, exclusion diets, micronutrients, and when to involve a dietitian. Emphasizes that diet supports medical care and is not a standalone cure.
Crohn's & Colitis Congress 2024: IBD Diet & Nutrition Research Updates
Recap of nutrition-focused presentations from the 2024 Crohn's & Colitis Congress. Highlights emerging diet trials, patient-reported outcomes, and practical themes clinicians discussed for Crohn's disease and ulcerative colitis.
Micronutrient Deficiency in Crohn's Disease
Overview of common vitamin and mineral shortfalls in Crohn's disease, including iron, B12, vitamin D, and folate. Explains why inflammation, surgery, and diet restriction can raise deficiency risk and why labs matter.
NIH Office of Dietary Supplements: Dietary Reference Intakes (DRI)
Official NIH hub for U.S. Dietary Reference Intakes. Reference amounts for energy, protein, vitamins, and minerals vary by age and sex. IBDPal uses these values as baseline daily tracking goals, not personalized prescriptions.
Dietary Reference Intakes (DRI): Summary Report
Authoritative U.S. reference values for macronutrients, vitamins, and minerals. Complements the NIH ODS DRI tables. IBD teams adapt general DRIs when inflammation, malabsorption, or steroid use changes individual needs.
Crohn's Disease
NIDDK's Crohn's disease hub covers definition and facts, symptoms and causes, diagnosis, treatment, eating and nutrition, and clinical trials. Useful as a public, government-backed starting point for patient education.
Ulcerative Colitis
NIDDK's ulcerative colitis hub explains UC basics, symptoms, diagnosis, treatment options, diet and nutrition, and research links in patient-friendly language.
Crohn's Disease
MedlinePlus brings together Crohn's disease summaries, tests, treatments, living-with resources, clinical trials, journal article links, and patient handouts from NLM, NIH, and other trusted organizations.
Ulcerative Colitis
MedlinePlus collects UC summaries, diagnosis and test resources, treatment links, clinical trial links, journal article references, and patient handouts in one government health topic page.
Inflammatory Bowel Disease (IBD) Basics
CDC overview of IBD as a lifelong group of diseases, including Crohn's and ulcerative colitis, with symptoms, complications, medication categories, and quality-of-life context.
IBD Facts and Stats
CDC summarizes U.S. IBD prevalence estimates, differences across groups, health behaviors, comorbidities, and health care cost patterns, including estimates of 2.4 to 3.1 million people affected.
Clinical Trials for Crohn's Disease
NIDDK explains what Crohn's clinical trials are, how ClinicalTrials.gov lists studies, and examples of NIDDK-supported research such as IBD genetics and microbiome work.
Clinical Trials for Ulcerative Colitis
NIDDK explains ulcerative colitis clinical studies, ClinicalTrials.gov search pathways, and NIDDK-supported work such as IBD genetics and pediatric colitis response research.
ClinicalTrials.gov: Inflammatory Bowel Diseases
Official U.S. registry for clinical studies. Patients can search IBD studies by condition, recruiting status, location, sponsor, and study type, then discuss possible participation with their care team.
Probiotics: What You Need To Know
NCCIH explains probiotics, research uncertainty, safety considerations, and why supplement use should be discussed with clinicians, especially for people with serious illness or immune concerns.
Biosimilar and Interchangeable Biologics: More Treatment Choices
FDA consumer education explaining biosimilars and interchangeable biologics, how they compare with reference biologics, and why they may increase treatment options and access.
How IBDPal nutrition baselines work
- Baseline macronutrient and micronutrient targets follow U.S. Dietary Reference Intakes (DRI) from NIH, adjusted by age and sex.
- Calorie, protein, and fluid estimates also consider basic profile inputs such as current weight. A single formula like 30 kcal per kg is not enough for every patient.
- Higher calorie, protein, vitamin, or mineral needs during active disease, malabsorption, or deficiency are clinical decisions made with your gastroenterologist or IBD dietitian.
- IBDPal tracks food and fluids against general reference levels. It does not prescribe supplements or replace medical nutrition therapy.
- AGA guidance and IBD research explain when labs and dietitian visits matter. DRI tables define population reference ranges; your team personalizes targets.
