Results from national surveys in children in Scotland suggest that intakes of saturated fatty acids (SFA) and non-milk extrinsic sugars (NMES) decreased between 2006 and 2010(1). These surveys assessed diet using the Scottish Collaborative Group Food Frequency Questionnaire (FFQ), and the National Diet and Nutrition Survey (NDNS) databank was used for the nutrient analysis. In 2010, the FFQ nutrient composition database was updated to reflect changes in the NDNS databank as many food codes used in 2006 were no longer present in the databank and nutrient composition of some foods had been updated. The main changes were in the codes for pizza, spreads, crisps and savoury snacks. We aimed to assess to what extent updates to the FFQ nutrient composition database influenced the observed changes in SFA and NMES intakes between 2006 and 2010.
