Adolescents’ non-core food intake: a description of what, where and with whom adolescents consume non-core foods

Abstract

AbstractObjectiveLittle is known about adolescents’ non-core food intake in the UK and the eating context in which they consume non-core foods. The present study aimed to describe types of non-core foods consumed by British adolescents in total and across different eating contexts.DesignA descriptive analysis, using cross-sectional data from food diaries. Non-core foods were classified based on cut-off points of fat and sugar from the Australian Guide to Healthy Eating. Eating context was defined as ‘where’ and ‘with whom’ adolescents consumed each food. Percentages of non-core energy were calculated for each food group in total and across eating contexts. A combined ranking was then created to account for each food’s contribution to non-core energy intake and its popularity of consumption (percentage of consumers).SettingThe UK National Diet and Nutrition Survey 2008–2011.SubjectsAdolescents across the UK aged 11–18 years (n 666).ResultsNon-core food comprised 39·5 % of total energy intake and was mostly ‘Regular soft drinks’, ‘Crisps & savoury snacks’, ‘Chips & potato products’, ‘Chocolate’ and ‘Biscuits’. Adolescents ate 57·0 % and 51·3 % of non-core food at ‘Eateries’ or with ‘Friends’, compared with 33·2 % and 32·1 % at ‘Home’ or with ‘Parents’. Persistent foods consumed across eating contexts were ‘Regular soft drinks’ and ‘Chips & potato products’.ConclusionsRegular soft drinks contribute the most energy and are the most popular non-core food consumed by adolescents regardless of context, and represent a good target for interventions to reduce non-core food consumption.
