Join the NOURISH Autoimmunity Challenge

Integrating nutrition in autoimmune research

The National Institutes of Health (NIH) invites you to join the NOURISH Autoimmunity Challenge, a national crowdsourcing competition designed to spark innovative ideas that integrate diet and nutrition into autoimmune disease research.

Autoimmune diseases affect millions of Americans, yet the role of nutrition in their onset, progression, and management remains underexplored. Through NOURISH, we seek bold, community-driven ideas that can transform research and improve lives.

With up to $150,000 in total prizes, your ideas could help reimagine how diet and nutrition are studied in autoimmune disease.
