Nordic network on dietary survey methodology 2019-2020

In 2019, the Nordic network on dietary surveys compared results regarding 24 h recalls, if the method was used in a systematic Nordic set up. A standardized central food list for 7 days was entered into national nutrients calculation systems and the intakes of individual food groups and nutrients on each day and as a daily average of the 7 days were compared. Results were presented at an online workshop on November 20th, 2020. In addition to the country specific presentations of the analysis, each country also gave a presentation on the latest national dietary survey. Despite standardized input, there were many differences in the results. The presentations on national dietary surveys showed differences and similarities of conducting dietary surveys and elucidated a lot of the common challenges researchers face. Many topics could be further elucidated on future network meetings.
