About this trial
The investigators propose to develop and validate MyRareDiet® (MRD) to address an unmet need in the inborn errors of metabolism (IEM) population to assist with dietary management designed to increase adherence and compliance to treatment guidelines, while facilitating the collection of dietary data from individuals with IEM for research purposes.

Treatments tested in this trial
MDR diet assessment
Other interventionParticipants 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.
24 hour recall
Other interventionA 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.
