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.

Objective biomarkers can validate your dietary intake. For example, blood levels of alkylresorcinols can confirm whole grain consumption, while DHA/EPA levels reflect fish intake. These tools help ensure you are meeting your nutritional goals accurately.

Examples of suggested nutritional biomarkers are shown in Table 1... plasma concentration of alkylresorcinol is considered a biomarker of the intake of whole grains [14]... combination of sucrose or fructose with erythronic acid is a urinary biomarker for sugar intake [31]... n-3 fatty acids: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) status [38].
