What is ASA24-Canada?
A Canadian adaptation of the Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24-Canada), developed by the Food Directorate at Health Canada in collaboration with NCI, has been freely available since April 2014.
ASA24-Canada makes use of the ASA24 Respondent and Researcher Websites, with modifications made to reflect the Canadian food supply. Foods unique to Canada have been added and those not available in Canada removed. Many changes reflect differences in brand name and fast food restaurant items between the two countries. As well, metric measurements have been added.
The adaptation of the ASA24 system makes it possible to collect dietary recall data, and for the 2016 version, food record data, in a range of studies in Canada using a tool tailored to the Canadian context.
What is the most current version of ASA24-Canada?
An updated version (ASA24-Canada-2016) was released in October 2016. View a comparison of current and past versions of ASA24, including the 2016 and 2014 versions of ASA24-Canada.
The development of ASA24-Canada-2016 was supported by Health Canada's Food Directorate, the Alberta Cancer Foundation, and the Canadian Partnership Against Cancer through funds allocated to Alberta's Tomorrow Project, and contributions from a Canadian Institutes of Health Research New Investigator Award provided to Dr. David Hammond at the University of Waterloo.
What nutrient and dietary supplement databases are used in ASA24-Canada?
The ASA24 nutrient database was adapted using the Canadian Nutrient File (CNF2015) and a Canadian recipe database used for surveillance.
A small proportion (8%) of codes from the 2009-2010 (version 5.0) and 2011-2012 Food and Nutrient Database for Dietary Studies (FNDDS) codes could not be matched to Canadian foods. For these, FNDDS codes were used and nutrient values were adjusted to account for fortification differences when necessary.
Portion sizes were assigned Canadian gram weights if available. If not, FNDDS gram weights consistent with Canadian portion sizes were used. For items in the CNF and Canadian recipe database without complete nutrient profiles, appropriate FNDDS values were used when available.
ASA24-Canada-2016 also links to the United States Department of Agriculture's 2011-2012 Food Patterns Equivalents Database and provides amounts of food groups and other dietary components (e.g., added sugars, oils).The dietary supplement database used in ASA24-Canada-2016 is based on the Licensed Natural Health Products Database and supplemented by the NHANES Dietary Supplement Database 2007-2008.
