Biomarkers of nutrition provide an objective, proximal measure of dietary intake and metabolic status, overcoming the inherent biases and limitations of self-reported dietary assessment methods.
To accurately assess your nutrition, rely on objective biomarkers (like blood or urine tests) rather than just self-reported food logs. Self-reporting is prone to memory errors and bias. Biomarkers offer a precise, proximal measure of what you actually consume and how your body metabolizes it, enabling better personalized dietary recommendations.
GoodSupportsHIGH confidence
Biomarkers provide a more proximal measure of nutrient status than dietary intake. Generally speaking, a nutritional biomarker is a characteristic that can be objectively measured in different biological samples and can be used as an indicator of nutritional status with respect to the intake or metabolism of dietary constituents [6].

- Specific biomarkers exist for various food groups and nutrients, such as alkylresorcinols for whole grains, carotenoids for fruits/vegetables, and DHA/EPA for fish intake, allowing for objective validation of dietary intake.Good
- Integrative nutritional biomarkers, which combine exposure and effect data, enable precision nutrition by accounting for inter-individual genetic and epigenetic variations in response to diet.Moderate
