MyRareDiet A Novel Diet Tracking Tool

Participants will record their dietary intake on the MyRareDiet (MRD) app and nutrient content will be assessed to validate MRD compared to a traditional interviewer assessed 24 hour recall.

A trained nutritionist will conduct a telephone multi-pass 24 hour diet recall on 3 randomized nonconsecutive days. The dietary intake will be analyzed using NDSR and metabolic pro and nutrient intake will be compared to the nutrient intake assessed with the MRD app.
