Se estudió a 815 sujetos de 65 a 94 años de edad que completaron un cuestionario sobre sus hábitos dietéticos, y que posteriormente fueron seguidos una media de 4 años. Un total de 131 participantes desarrollaron Alzheimer durante el período de seguimiento. Los resultados muestran que aquellos que consumían pescado al menos una vez por semana presentaron un 60% menos riesgo de desarrollar la enfermedad neurológica que aquellos que rara vez consumían pescado.
La ingesta total de ácidos grasos poliinsaturados n-3 también se asoció con un menor riesgo de Alzheimer, en concreto del 70% tras ajustar otros factores.
Estos resultados, en combinación con los de investigaciones previas, sugieren, a juicio de los autores, que el consumo de pescado, ensaladas con aceite y nueces pueden prevenir el riesgo de Alzheimer.
