For Researchers using earlier versions of the ASA24 system who have switched mid-study to a 2018 version:
- The underlying nutrient and food group databases for ASA24-2018 and ASA24-2016 are not directly comparable (see a table comparing the features of all versions of ASA24). The only difference is that the 2018 version includes some new foods and supplements from FNDDS and DSD 2013-2014.
- The underlying nutrient and food group databases for versions prior to ASA24-2016 are not directly comparable (see a table comparing the features of all versions of ASA24). SAS code is available to update analytic files from older versions to a comparable food group database as ASA24-2016. ASA24-Canada-2014 and ASA24-Canada-2016 use the same nutrient databases but the 2014 version, unlike the 2016 version, does not include food groups. It is not possible to rerun ASA24-2011, ASA24-2014, or ASA24-Canada-2014 Respondent data using ASA24-2016 or ASA24-Canada-2016.
