This report aims to investigate the types of food and drink that may be misreported by comparing food and drink intake data from the self-administered 24-hour dietary recall method used in two national diet surveys - The 2021 Scottish Health Survey (SHeS) and the 2024 Dietary Intake in Scotland’s cHildren (DISH) survey, with retail purchase data from Worldpanel by Numerator (‘Worldpanel data provided to FSS’). It also explores how misreporting may affect estimates of energy intake and nutrients such as fat, saturated fat, carbohydrates, fibre, total sugars and sodium. The report concluded by identifying ways to improve dietary reporting using the self-administered 24-hour dietary recall method and recommending further research to improve understanding of misreporting.
