Poster Theater Flash Sessions will feature flash talks followed by discussion time by a poster board. Each speaker will have up to 4 minutes (and up to 3 slides) to highlight major findings and other noteworthy or interesting details. After the flash talks, presenters will stand by their poster for dialogue with NUTRITION 2026 attendees. Complete abstract text for each abstract which will be presented at NUTRITION 2026 will be available on July 24.
