“…Few studies have assessed the energy contribution of ultraprocessed foods in children's diets, which is recognized as an important determinant of the nutritional quality of diets (Food and Agriculture Organization, ). Studies carried out with Brazilian children under 10 years old showed that about 40% (variation between 36.1% and 48.6%) of total dietary energy intake came from ultraprocessed foods (Barcelos, Rauber, & Vitolo, ; Bielemann, Santos, dos Santos Costa, Matijasevich, & Santos, ; Leite et al, ; Karnopp et al, ; Sparrenberger, Friedrich, Schiffner, Schuch, & Wagner, ; Rauber et al, ), whereas amongst Colombian children aged 5 to 12 years old, the contribution was 34.4% (Cornwell et al, ). Then, the share of ultraprocessed foods in children's diets in the United Kingdom as observed in this study was almost 1.6 times higher than those observed in the Latin American countries (Barcelos et al, ; Bielemann et al, ; Cornwell et al, ; Karnopp et al, ; Leite et al, ; Rauber et al, ; Sparrenberger et al, ), nations in which dietary patterns are based on unprocessed and minimally processed foods.…”
