My Rare Diet Study - Coming Soon

We developed a mobile app called MyRareDiet®, which is intended to document nutrition intake, facilitate data collection, reduce study burden for families, and in the future connect this information with patient health outcomes. MyRareDiet® is designed to address a significant unmet need in the patient community and in research, and to assist with dietary management designed to increase adherence and compliance that leads to improved outcomes. 

NUCDF is excited to announce recruitment coming soon.
