Additionally, this study presents data on a neglected area of research, namely the influence of personal and socio-environmental factors on food choice at breakfast among European adolescents. Our study shows that the personal factors ‘hunger’, ‘taste of the food’, ‘concern for health’ and the socio-environmental factor ‘parents or guardian’ were the most important influences on the adolescents’ choice of food at breakfast. Similar findings have been shown in studies from the USA, from Sweden and from Australia
