“…It has been observed that food brought from home and breakfasts in the classroom generate less food waste in the school canteen (Farris et al, 2019); however, the schoolchildren who ate snacks high in saturated fat or calories in the morning, which cause loss of appetite at noon, were more likely to waste lunch food (Falasconi et al, 2015;Martins et al, 2020). School lunch food is adequate for schoolchildren's daily diet and is generally more nutritious than other foods, including those taken from home (Pagliarino, Santanera, & Falavigna, 2021). Schoolchildren eating habits are extremely different, as it could be associated with the regularity of meals, the kind of breakfast, even the age at which schoolchildren start smoking (Park, Choi, & Kim, 2015), as well as their appetite (Martins et al, 2016;Wu et al, 2019), as food is wasted more when the schoolchildren are not hungry (Betz et al, 2015) or are not satisfied with the taste of the food served (Qian et al, 2021;Talwar et al, 2021) or other sensory properties of the food (Tuorila et al, 2015;Martins et al, 2020).…”
