24-Hour Recalls

We offer:

  • data collection via 24-hour recalls or food records (in person or by telephone)
  • processing 24-hour recalls or food records after they have been collected using NDSR
  • training to use NDSR software by a certified data manager


We have a license with the University of Minnesota’s Nutrition Coordinating Center (NCC) for the Nutrition Data System for Research (NDSR) that includes state-of-the-art software for data entry and calculation of intakes for 108 nutrients. We use NDSR software to collect dietary data via telephone or in-person 24-hour recalls. This system uses a multiple-pass approach with prompts displayed throughout the interview to assist in data collection and review.

Portion Size Tools

We use Nasco food models to assist subjects in identifying their food portion sizes. For telephone interviews, we also use the Food Portion Booklet.


Includes entering food records into the latest version of NDSR software from paper forms; and 5-10% review of food records/recalls, outlier range checks and clean up of entry.

All interviewers must be trained either by previously trained staff or by our department in order to accurately collect and process dietary data. Our data manager has been trained and certified in the use of the NDSR system and serves as the trainer and quality control manager for our data entry staff. In addition to completing a detailed training program, the staff is monitored for quality control through random observation of interviews and double entry of selected recalls or records by the dietary data manager.

We offer one day training by our trained certified data manager in NDSR to learn how to collect and/or use NDSR software. We also offer group training by video web conference.

Cost for one full day of training on using NDSR dietary entry procedures for food records:
$500 for first person + $200 each additional person, same day
