Irish teenagers aged 13-17 years have previously been shown to have inadequate dietary fibre (DF) intakes (1). The objective of the present research was to identify the dietary patterns influencing DF intake in Irish teenagers. Data from the National Teens' Food Survey (NTFS) was used for this analysis (http://www.iuna.net). Dietary intake data from the NTFS were analysed using WISP g (Tinuviel Software, Llanfechell, Anglesey, UK), which is based on the 6th edition of McCance and Widdowson's The Composition of Foods (2). In the present analysis, the contribution of food groups (g and %) to mean daily DF intakes by a third of DF intake (stratified for age and gender) are reported in the 13-17-year-old teenagers. The mean daily energy intakes were 6.7 MJ (1598 kcal), 8.3 MJ (1994 kcal) and 9.9 MJ (2347 kcal), in low, medium and high DF consumers, respectively. The food groups that account for the greatest proportion of the difference in intakes between high (the top third) and low (the bottom third) consumers of DF are also reported.
