          Abstract

          Resumen Introducción: la modernización de la sociedad ha supuesto una serie de cambios en los hábitos alimentarios y la práctica de actividad física de la población, así como una mayor generación de desperdicios alimentarios en los hogares. Objetivo: estudiar el desperdicio de alimentos en el hogar, valorando al mismo tiempo los hábitos alimentarios y estilos de vida de la población estudiante universitaria. Material y métodos: los datos se recopilaron mediante una encuesta estructurada y autoadministrada online en la que se midieron los hábitos alimentarios (cuestionario de frecuencia) y el nivel de actividad física (IPAQ-Short) de los sujetos participantes, así como el desperdicio de alimentos de sus comidas principales mediante un registro fotográfico de tres días distintos según el método Comstock, estimación visual por cuartos. Resultados: la mayor parte de los estudiantes no cumplen con las recomendaciones de frecuencia de consumo de cereales de grano entero, frutas, verduras, hortalizas, pescado y frutos secos, aunque la práctica de actividad física resultó ser alta. La media total del desperdicio, valorada en la escala de Comstock, se correspondió con un porcentaje del 14,5 %, desperdicio de tipo evitable principalmente. La carne fue el grupo de alimentos más consumido como fuente proteica, así como el de mayor desperdicio, junto con verduras y hortalizas. Conclusiones: este estudio enfatiza aun más la necesidad de un mayor número de intervenciones en términos de adquisición e implementación de habilidades para mejorar los comportamientos alimentarios saludables, así como para reducir el desperdicio de alimentos por parte de la población universitaria.

          Abstract Introduction: the modernization of society has brought about a series of changes in the dietary habits and practice of physical exercise in the population, as well as a greater generation of food waste in homes. Objective: to assess food waste at home and to evaluate the eating habits and lifestyles of university students. Material and methods: data were collected through a structured, self-administered online survey in which the eating habits (frequency questionnaire) and level of physical activity (IPAQ-Short) of the participating subjects were measured, as well as the waste from main meals through a photographic record of three days according to the Comstock method, visual estimation. Results: most of the students do not comply with the frequency recommendations for consumption of whole grain, fruits, vegetables, nuts and dried fruits, although the practice of physical activity is high, specifically moderate. The total average of waste as assessed with the Comstock scale corresponds to a percentage of 14.50 %, mainly avoidable waste. Meat was the most consumed food group as a source of protein, as well as the most wasteful along with vegetables. Conclusions: this study further emphasizes the need for a greater number of interventions in terms of acquisition and implementation of skills for improving healthy food behaviors, as well as for reducing food waste in university students.

            The Progressive Increase of Food Waste in America and Its Environmental Impact

            Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and CO2 emissions from decomposing food, impacts global climate change. Here, we calculate the energy content of nationwide food waste from the difference between the US food supply and the food consumed by the population. The latter was estimated using a validated mathematical model of metabolism relating body weight to the amount of food eaten. We found that US per capita food waste has progressively increased by ∼50% since 1974 reaching more than 1400 kcal per person per day or 150 trillion kcal per year. Food waste now accounts for more than one quarter of the total freshwater consumption and ∼300 million barrels of oil per year.
