What is the National Health and Nutrition Examination Survey (NHANES)?

The National Health and Nutrition Examination Survey (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States.


The study is typically carried out every two years by the National Center for Health Statistics (NCHS) which is part of the Centers for Disease Control and Prevention (CDC).


The NHANES dataset provides very comprehensive health data on the US population. The interview component covers demographic, socioeconomic, dietary, and health-related data and the examination component consists of medical, dental, and physiological measurements, as well as laboratory test data.


Since 1999, the data has been published every two years. Each data set is referred to as a ‘wave’ (e.g. 1999-2000, 2001-2002, 2003-2004, etc…).   Before 1999 there were various studies carried out dating as far back as the NHES I study (1959-1962).

The NHANES data is a vital resource for industry, researchers and governments. Organisations use this data as follows:


  • To access raw data files in .csv format for analysis based on food intake and health metrics.
  • To carry out food-based exposure and risk assessments for ingredients, contaminants or additives.
  • To determine which foods contain a given ingredient and to monitor the intakes of those
  • To assess the nutritional intakes of raw agricultural produce that is used in the food industry
  • To generate statistical data (e.g. means and various percentiles) on consumption values of different food commodities, including water
  • To monitor longitudinal trends of intake over time.
  • In models such as Creme Nutrition, Creme Food Safety or the Creme Dietary Intake Intelligence Tool to gain nutritional or food safety insights
