Abstract
La relación entre los alimentos que se consumen diariamente y su impacto
hacia el medioambiente es sumamente estrecha, más aún cuando estos son obtenidos a través de fuentes animales o a partir de fuentes vegetales. El siguiente proyecto tuvo como objetivo analizar la huella de carbono respecto a distintas sub-dietas pertenecientes a las dietas omnívoras y dietas veganas, que han surgido este último tiempo, tales como la sub-dieta basada en plantas, la vegana convencional, la mediterránea y la promedio chilena, con el fin de determinar sus emisiones de Gases de Efecto Invernadero (GEI), a través de los kg CO2e producidos durante todo el ciclo de vida de cada producto perteneciente a cada una de estas. A partir de la realización de minutas nutricionales para cada una de estas sub-dietas, se logró cuantificar las emisiones de GEI gracias a los valores obtenidos a través de distintos programas y revisiones bibliográficas referentes al tema. Se logró concluir que la sub-dieta basada en plantas fue la que menor huella de carbono generaba, debido a la preferencia de productos vegetales sobre los productos animales.
The relationship between the food consumed daily and its impact on the environment is extremely close, even more so when it is obtained from animal or plant sources. The following project aimed to analyze the carbon footprint of different sub-diets belonging to the omnivorous and vegan diets that have emerged recently, such as the plant-based sub-diet, the conventional vegan diet, the Mediterranean diet, and the average Chilean diet, to determine their Greenhouse Gas (GHG) emissions, through the kg CO2e produced throughout the life cycle of each product belonging to each of these diets. From the realization of nutritional minutes for each of these sub-diets, it was possible to quantify the GHG emissions thanks to the values obtained through different programs and bibliographic reviews on the subject. It was concluded that the plant-based sub-diet was the one that generated the lowest carbon footprint, due to the preference of plant products over animal products.
