Key Points

Review the methodology, analytical considerations, and policy applications of dietary assessment in the National Health and Nutrition Examination Survey (NHANES).
Examined continuous cross-sectional survey protocols collecting nationally representative samples of approximately 10,000 participants in 2-year cycles since 1999.
Assessed dietary monitoring through the 'What We Eat in America' initiative, which uses the USDA's Automated Multiple-Pass Method for two 24-hour recalls alongside targeted food-frequency questionnaires and detailed supplement inventories.
Continuous data collection enables estimation of usual dietary intake distributions by adjusting for day-to-day intake variation across large sociodemographic groups.
The survey integrates ongoing validation studies and expert input to adapt content for emerging public health priorities while monitoring foods, nutrients, and dietary patterns.
