    Abstract:
    This study was aimed at describing the snack consumption among Brazilian adolescents. The Brazilian National Dietary Survey (2017-2018) is a nationwide representative cross-sectional study that collected food consumption data from 8264 adolescents (10 to 19 years old); data from one 24-h recall were used, in which all foods and beverages consumed throughout the day prior to the interview were described along with the amount, unit of measurement, time, place and occasion of consumption (breakfast, lunch, dinner or snack). Snacks were classified as follows: (a) Morning snack: "Snacks" consumed between 6 AM and 12 PM; (b) Afternoon snack: "Snacks" consumed between 1 PM and 5 PM; (c) Evening snack: "Snacks" consumed between 6 PM and 5 AM. Individuals were categorised according to the number of "Snacks" per day (zero, one, two or three or more). Among the evaluated adolescents, 52.8% were female and 23.0% were overweight. The consumption of at least one snack per day was mentioned by 88.2% of the adolescents, with an average of 2.33 snacks per day. An afternoon snack was consumed by 70.0% of the adolescents. Snack consumption was related to higher mean daily energy intake and a greater contribution of carbohydrates, added sugar and trans fat to the total daily energy intake. 'Cookies & Crackers' and 'Fast Foods' were the groups that contributed the most to the energy intake provided by snacks, showing, therefore, that less healthy foods were relevant components of the snacks consumed. For their important contribution to food intake, snacking habits deserve attention among the topics covered in dietary guidelines.
