Capacidad saciante y tamaño de porción para comida y snack en universitarios mexicanos

Abstract

Un snack es una porción pequeña de alimentos consumida entre comidas principales con el fin de obtener energía. Su presencia en la dieta de adultos ha incrementado en la última década. El objetivo del estudio fue determinar el tamaño de porción ingerida y la percepción de la capacidad saciante esperada (CSE) de diferentes alimentos si son ofrecidos como “comida” o “snack”. Se diseñó y validó la encuesta para evaluar las elecciones de tamaño de porción ingerida y la CSE de 12 alimentos seleccionados a través del Análisis Descriptivo Cuantitativo (QDA). Participaron 453 estudiantes de 22±4,0 años, los resultados se evaluaron mediante análisis de varianza (ANOVA) con un nivel de confianza del 95%. En la mayoría de los alimentos (83,3%) la CSE fue mayor cuando eran “snack” que en “comida”. El tamaño de porción elegido en 5 alimentos fue menor cuando eran “snack” (p<0,05); para el resto de los alimentos no se mostraron diferencias significativas. Respecto al contenido energético ingerido en los dos tiempos de comida, únicamente dos productos, ampliamente reconocidos como snacks, no presentaron diferencias. La densidad energética ingerida de los alimentos estudiados sería mayor si lo consumieran como comida vs snack (p<0,05). Los resultados concuerdan con la evidencia previa sobre los determinantes para consumo de alimentos: los ingredientes del alimento y su complejidad, la saciedad percibida y sus características orosensoriales. Se puede concluir que el contenido energético y nutrimental no fue tomado en cuenta al elegir la cantidad de alimento independientemente de si se ingiriera en “comida” o “snack”. ‘Snack’ is a small portion of food consumed between main meals to obtain energy. Its presence in the diet of adults has increased in the last decade. The objective of the study was to determine the size of the ingested portion and the perception of the expected satiating capacity (ESC) of different kinds of food if they are offered as ‘meals’ or ‘snacks’. A survey was conducted to evaluate the ingested portion size choices and the ESC of 12 selected foods through QDA methodology. 453 students aged 22±4.0 years participated in the study, results were analyzed with ANOVA (95% as confidence level). In most of the given choices of food (83.3%) the ESC was greater when they were offered as ‘snacks’ compared to ‘meals’. The portion size chosen for five food options was smaller when they were considered ‘snack’ (p<0.05); for the rest of the food options, no significant differences were shown. Regarding the energy content ingested at the two mealtimes, only two products, widely recognized as snacks, did not present statistical differences. The consumed energy density of the food choices studied was higher when they were chosen to be consumed as meals vs snacks (p<0.05). The results correspond with previous evidence about the determinants for food consumption: ingredients and complexity of the foods, perceived satiety, and its sensorineural characteristics. It can be concluded that energy and nutritional content was not considered when choosing the amount of food regardless of whether it was ingested as a ‘meal’ or as ‘snack’.
