    About NCHS -- Nutrition data -- Dietary intake and behavior -- Biomarkers of nutritional status -- Use of NHANES nutrition data for standards and policy.

    The CDC’s National Center for Health Statistics (NCHS) is the nation’s principal health statistics agency, providing data to identify and address health issues. NCHS compiles statistical information to help guide public health and health policy decisions.

    Collaborating with other public and private health partners, NCHS employs a variety of data collection mechanisms to obtain accurate information from multiple sources. This process provides a broad perspective to help us understand the population’s health, influences on health, and health outcomes.

    NCHS has been collecting dietary data on the U.S. population for more than 40 years. The primary data source for monitoring nutrition is the National Health and Nutrition Examination Survey (NHANES), using personal interviews, standardized physical examinations and laboratory tests. Through NHANES, NCHS obtains nationally representative data on dietary intake and behaviors, biomarkers of nutritional status, body measurements (such as height and weight) and body composition.

    Federal agencies, researchers, educators, health care providers, and policymakers use these data to: Assess and monitor the nutritional status of the U.S. population; Identify nutrient deficiencies/excess; Examine the association of diet with health and disease; Inform nutrition programs; Contribute to nutrition policy development; Examine the impact of nutrition policies over time.
