Intake Technical Note: Assessing the Relationship Between Dietary Nutrient Intake Data and Nutrient Biomarker Data

February 20, 2024

This Intake Technical Note provides an overview of some key issues that should be considered before assessing the relationship between dietary nutrient intake data and nutrient biomarker data. Four nutrients (iron, zinc, vitamin A, and folate) are used as case study examples to discuss these different issues and how they may impact the association (or lack thereof) observed between dietary nutrient intake and nutrient biomarker data.
