Resumen
OBJETIVOS:Evaluar los efectos del consumo de ácidos grasos omega 3 en forma de suplementos, complementos o alimentos sobre la función cognitiva de los adultos.
MÉTODOS:Se realizó una revisión de la literatura en las bases de datos Medline y Embase, buscando ensayos clínicos, estudios observacionales, revisiones sistemáticas y estudios experimentales que relacionaran los ácidos grasos omega 3 con función cognitiva y Alzheimer.
RESULTADOS:La mayoría de los estudios relacionó la suplementación de cápsulas con omega 3, el consumo de pescado u otros alimentos con contenido de omega 3, con resultados en pruebas de función cognitiva, desenlace de enfermedad o imágenes diagnósticas, encontrando en general efectos benéficos, que parecen ser mayores en personas sanas y con mejor función cognitiva de base. Hubo diferencias en los resultados encontrados en los ensayos clínicos y revisiones sistemáticas, que podrían atribuirse a la variabilidad en las dosis de la suplementación, el tiempo de seguimiento y la manera en que se midió la función y el deterioro cognitivo.
CONCLUSIÓN:El consumo de ácidos grasos omega 3 en forma de suplementos, complementos o alimentos ricos en estos como el pescado parece tener efectos benéficos en la función cognitiva de las personas adultas.
