Using recovery biomarkers (such as doubly labeled water and urinary nitrogen) is the most effective method to validate self-reported dietary intake and quantify measurement error.
For accurate dietary assessment in research, use recovery biomarkers like doubly labeled water or urinary nitrogen to validate self-reported data.
StrongSupportsHIGH confidence
Recovery biomarkers are based on precise and quantitative knowledge of the physiological balance between intake and output and can provide a dose–response relationship with intake. They are sensitive and time-dependent and are not substantially affected by inter-individual differences in metabolism. They are often used as reference measures to validate self-reported intakes.
Why this rating
Explicitly defined and supported by references to the OPEN study and other validation projects.
