The current version of ASA24 in the United States is ASA24-2022; however, NCI plans to release the next version of ASA24 in March 2024. Researchers collecting data using ASA24-2022 will need to transition their studies to ASA24-2024 by March 2025.

New US versions of ASA24 are typically released every two years, to incorporate underlying biennial food and nutrient databases from the United States Department of Agriculture. New versions of ASA24 may also include additional functionalities and/or updates to the user interface.

As with all versions since the release of ASA24-2016, the ASA24-2022 respondent website uses a responsive design, allowing it to be used on smartphones, tablets, laptops, and desktops. This allows study participants to enter dietary intake data at any time and from any location with Internet service.

The following features are new to the 2022 version of ASA24:

  • New portion size food images have been added for some popular foods.
  • Nutrient, food group, and supplement databases were updated to include:

Other features of ASA24-2022 include:

  • The user interface is written in HTML5. This enables ASA24 to work on all common web browsers.
  • Respondents can complete single- or multi-day food records (also known as food diaries) and 24-hour recalls.
  • Supplement intake is collected at the same time as foods and beverages, rather than in a separate module. This allows participants to report supplement intake as part of what they consume on a given day, with corresponding time stamps that may be useful in examining patterns of intake across the day.
  • Researchers have the option to provide respondents with a Respondent Nutrition Report, which shows how their intake on the day they completed a 24-hour recall or food record compares to country-specific dietary guidance and nutrient requirements.
  • Respondents can build recipes and use these recipes in subsequent intakes.
  • A sleep module is available in the ASA24-2022 as it was with ASA24-2020. Researchers have the option to ask respondents about sleep timing, duration, and quality. This will allow them to examine the associations between sleep and dietary intake, timing of eating, and other variables in the context of the 24-hour day.
  • Tips and guidance are available within the respondent website via a Help Center and icons on the screen; andQuick Start Guides are available for study staff and respondents.
