Researchers unlock precision nutrition research with biomarkers of food intake

15 Aug 2024 — Biomarkers of food intake (BFIs) can increase the objectivity and accuracy of dietary assessments, which is crucial to enable precision nutrition. In a review article, scientists from the University of Copenhagen, Denmark, provide a comprehensive overview of BFIs measured in blood and urine and present a roadmap to develop and implement these tools to enable precision in nutrition research. 

A biomarker of food intake measures the consumption of specific food groups, foods or components to estimate recent or average intake. BFIs are circulating or excreted food constituents’ metabolites, usually non-nutrients.
