Foods and Analytes in the Total Diet Study

Please note: The FDA will be updating this page with new information about our efforts to modernize the Total Diet Study, in the near future. The modernization efforts include data management, methods, data quality standards, and study design improvements. In October 2017, a pilot program was initiated to test a more robust, population-based sample collection procedure. These improvements will help the FDA to continue our decades long effort to study and better understand Americans’ dietary exposure to toxic and nutritional elements, pesticides, industrial chemicals, and radionuclides.

The list of foods analyzed for the TDS underwent a major revision in 1991 and again in 2003, to reflect changes in average consumption patterns. Minor revisions to the list occur on an ongoing basis; for example, we delete products from the list that are no longer available in the retail setting. The specific foods and beverages we have analyzed for specific nutrients and chemical contaminants are displayed in the Food/Analyte Matrix (PDF:169KB).

The general categories of foods included in the TDS are:

  • baby foods
  • beverages
  • dairy products
  • eggs
  • food mixtures
  • fruits and fruit juice
  • grain products
  • legumes, nuts, seeds
  • meat, poultry, fish
  • fats and oils
  • sweets
  • vegetables

See Analytical Methods for a list of the analytical methods.
