Assessing Dietary Intake of Selected Food Components Using Short Questionnaires
Sponsor: Institute of Nutrition, Slovenia (Nutris)
Summary
The aim of the study is to validate short questionnaires for assessing dietary intake of selected food components, with a focus on dietary fibre and iron. Two internationally developed short questionnaires (FiberScreen \[for dietary fibre\] and IRONQ-FFQ \[for iron\]) were adapted to the Slovenian context and will be compared with the standard 24-hour dietary recall method.
