The Claim
MyFitnessPal demonstrates poor inter-rater reliability for sodium and sugar intake reporting among Canadian endurance athletes, with intraclass correlation coefficients of 0.419 and 0.348 respectively, indicating substantial inconsistency between users when logging identical food items, particularly among male athletes, which limits its validity for accurate dietary assessment in research or clinical settings.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
MyFitnessPal isn’t very reliable when it comes to tracking sodium and sugar — different people log the same foods differently, especially men, so it might not be good for studies or health advice.
See the scientific wording
MyFitnessPal exhibits poor inter-rater reliability for sodium and sugar among Canadian endurance athletes, with intraclass correlation coefficients of 0.419 and 0.348 respectively, indicating substantial inconsistency between users when entering identical food records, particularly among men, which limits its usefulness for accurate dietary monitoring in research or clinical practice.
What the research says
1 studyThe study found that when different people logged the same food in MyFitnessPal, they got very different results for sodium and sugar—especially men—just like the claim says.
