The Scottish Dietary Goals (SDGs) were published to promote healthier diets. The higher cost of healthier diets may be a barrier to their adoption by households in deprived areas. The aim was to estimate dietary intakes relevant to the SGDs, derived from purchase data of food and drinks brought into the home by area of deprivation. Methods A cross-sectional study of estimated intakes of food and nutrients, and on fruit and vegetables (F&V) specifically, from Kantar Worldpanel household food

Results Diets of households were further from achieving the SDGs as deprivation increased. Linear regression showed that estimated intakes of oil rich fish decreased, and red and processed meat increased with increasing deprivation (both p<0.001), while estimated intakes of F&V decreased (p<0.001) mainly because of lower amounts of fresh F&V (p<0.001). Negative linear associations were observed between deprivation and the amount spent per person on F&V (P<0.001), and the amount spent per 100g of F&V (p<0.001). Conclusions This study provides further insights into the relationship between social deprivation and diet quality in Scotland, notably in amounts of fresh F&V purchased. Estimation of food and nutrient intakes relevant to the Scottish Dietary Goals The equalized per person estimated intakes of fruit and vegetables, red and processed meat, oil-rich fish, salt, fibre, and percentage energy from fat, saturated fat and non-milk extrinsic sugars (NMES), which is a definition similar to "added sugars", along with energy density were calculated, and compared to SDGs. Energy density: Energy density (kcal/100g) of the food purchased was calculated from the contribution of all food and milks, but excluded all drinks (tea, coffee, water, Sci Food Agric. 2007;87:930-944. 7.
