The NOURISH (Nutrition for OUR Immune System Health): Autoimmunity Challenge is a competition hosted by the NIH. The challenge seeks innovative ideas on integrating diet and nutrition studies into autoimmune disease research, focusing on dietary interventions that are feasible, testable, scalable, and broadly impactful. Participants are encouraged to explore the role of diet in autoimmune disease inception, progression, flares, and symptom management.

This opportunity is open to individuals, teams, and entities including people living with autoimmune disease, patient advocacy groups, caregivers, dietitians, nutritionists, lifestyle medicine experts, physicians, and scientists.

The deadline is December 4, 2025. To learn more visit the website here.
