The National Institutes of Health (NIH) announced on March 30, 2026, that it awarded $10,000 prizes to 15 scientific teams across the United States for their innovative submissions to the Nutrition for Our Immune System Health (NOURISH): Autoimmunity Challenge. The competition sought novel ideas integrating diet and nutrition into autoimmune disease research, aiming to better understand how dietary interventions may influence disease onset, progression, flares, and symptom management.
Autoimmune diseases affect over 8% of the U.S. population, impacting an estimated 23 to 50 million Americans. Despite this prevalence and the significant economic burden of these conditions, the role of diet and nutrition in autoimmune disease remains underexplored. The NIH challenge invited a broad community of researchers, clinicians, patients, caregivers, and advocacy groups to submit scalable, feasible approaches with potential to advance knowledge and care.
Thematic Areas of Awarded Research
The winning projects addressed one or more of four key themes:
- Effectiveness of Dietary Interventions in Autoimmune Disease: Proposals in this category focused on interventional studies testing specific diets or therapeutic dietary patterns in autoimmune populations. These approaches aim to assess feasibility, clinical outcomes, disease activity, and symptom management through structured dietary interventions.
- Microbiome, Immune, and Multi-Omics Mechanisms: Several teams explored mechanistic, biomarker-driven research linking diet, the gut microbiome, and immune system activity. Their projects incorporated proteomics, microbiome analysis, and other multi-omics technologies to elucidate biological pathways by which nutrition may impact autoimmune disease onset and flares.
- Personalized, Data-Driven, and Predictive Nutrition: Innovative approaches in this theme utilized patient-reported outcomes, digital health tools, and predictive modeling to develop personalized dietary optimization methods. These data-driven strategies aim to improve disease management and enhance patients’ quality of life.
- Community Voice, Landscape Assessment, and Patient-Centered Frameworks: Submissions emphasized patient-centered frameworks, incorporating the lived experiences of people with autoimmune diseases. These projects foster community engagement and interdisciplinary collaboration among patients, caregivers, clinicians, and advocacy organizations to shape relevant research priorities and outcomes.
The NIH Office of Autoimmune Disease Research led the NOURISH Challenge, which generated many competitive submissions demonstrating thoughtful, scientifically rigorous, and patient-centered planning. Each winning entry will receive $10,000 to further develop their proposals, with the goal of producing innovative solutions benefiting Americans living with autoimmune diseases.

Why it matters
Autoimmune diseases are widespread and costly, yet the influence of diet and nutrition on disease mechanisms and symptom management is poorly understood. By fostering innovative, multidisciplinary research at the intersection of nutrition and immunology, the NIH aims to uncover new strategies for prevention and treatment. Engaging patients and communities in research design enhances the relevance and potential impact of findings, improving care for millions affected by autoimmune conditions.
