Alimentos ricos en ácidos grasos v-3 libres de contaminantes y aptos para vegetarianos, y su importancia en el desarrollo neurológico normal

Ángeles Molina-Peralta, Núria Mach

Resumen


Los ácidos grasos poliinsaturados esenciales de cadena larga v-3 como el ácido a-linolénico (ALA) y sus derivados, ácido eicosapentaenoico (EPA) y ácido docosahexaenoico (DHA), intervienen en la función y el crecimiento del tejido nervioso como componentes estructurales de las membranas neuronales. En vegetarianos y veganos, la ingesta de v-3 por parte de la madre durante el embarazo y la lactancia debe proceder de recursos no animales, limpios de metales pesados y dioxinas para asegurar el normal desarrollo de las estructuras neuronales en los niños. Se consultaron estudios científicos en modelos animales, celulares, ensayos clínicos y revisiones en las siguientes bases de datos electrónicas especializadas: PubMed central (PMC)-NBCI, Elsevier Journal, Scielo España, Scirus, y Science Direct, para establecer el estado actual del potencial efecto del consumo de alimentos ricos en v-3 como las algas, hongos, bacterias marinas y otras fuentes vegetales, aptas para vegetarianos y veganos, sobre el normal desarrollo neurológico infantil.
