Abstract
En la actualidad, existe una clara tendencia hacia dietas más sostenibles y saludables, como pueden ser las dietas basadas en vegetales cuyo seguimiento está aumentando considerablemente a nivel global. Sin embargo, los estudios científicos sobre su repercusión en el estado nutricional y los parámetros relacionados con la salud son escasos en España. Esta Tesis Doctoral se centra en valorar el estado nutricional de población vegetariana española y en conocer los efectos del consumo de un complemento alimentico rico en ácido docosahexaenoico (DHA), un ácido graso omega-3 (n-3) de cadena larga que es fundamental para el desarrollo cognitivo, multitud de funciones cerebrales y para la visión. El DHA no es un ácido graso esencial ya que puede sintetizarse a partir del ácido alfa-linolénico (ALA), pero el porcentaje de conversión es muy bajo...
Currently, there is a clear trend towards more sustainable and healthy diets, such as plant-based diets whose following is increasing considerably globally. However, scientific studies on its impact on nutritional status and health-related parameters are scarce in Spain. This Doctoral Thesis focuses on assessing the nutritional status of the Spanish vegetarian population and the effects of consuming a food supplement rich in docosahexaenoicacid (DHA), a long-chain omega-3 fatty acid that is essential for cognitive development,a multitude of brain functions and vision. DHA is not an essential fatty acid as it can be synthesised from alpha-linolenic acid (ALA), but the conversion rate is very low. The main dietary sources of DHA are fatty fish, which are absent in vegetarian diets. Alternatively, marine microalgae are an ideal plant-based source due to their high concentration of DHA...
