ÁMSTERDAM, December 10, 2015 /PRNewswire/ --

¿ Pueden los suplementos dietéticos específicos ralentizar el deterioro del cerebro como resultado del envejecimiento? La doctora Lorenza Colzato, investigadora del Instituto para la Investigación Psicológica de la Universidad de Leiden, investigará esto junto con algunos de sus compañeros investigadores europeos. Para esto, los científicos han recibido un subsidio de poco menos de un millón de euros por Joint Programming Initiative 'A Healthy Diet for A Healthy Life' (JPI HDHL).

Los investigadores estudiarán diversos aspectos, incluyendo el efecto del aminoácido triptófano y un probiótico multiespecies específicamente desarrollado. Quieren comprobar si la administración de estos suplementos tiene un efecto positivo sobre la cognición social de los ancianos (la manera en que se ven a ellos mismos y a otros). Esto tiene que ver con la selección, interpretación, recuerdo y uso de la información con el fin de evaluar los asuntos y tomar decisiones. La cognición social generalmente se deteriora con la edad, y el equipo de investigación quiere saber si este proceso puede ser retrasado.

Envejecimiento saludable

Esta es la primera vez que se realiza una investigación sobre el efecto de los probióticos y el triptófano en el funcionamiento social en personas mayores. Particularmente en este grupo, una buena cognición social es importante para mantener la vitalidad y buena salud. Si los resultados son positivos, la suplementación con triptófano y probióticos puede contribuir a un envejecimiento más saludable.

Triptófano

El triptófano es uno de los veinte aminoácidos que ocurren naturalmente en el cuerpo humano. El triptófano desempeña un papel importante en la producción de serotonina, un neurotransmisor (una sustancia en el cerebro) que está ligado al estado de ánimo, apetito, sueño y emoción, entre otras cosas. El triptófano se puede encontrar en alimentos como plátanos, leche, chocolate y garbanzos. Algunos suplementos dietéticos contienen triptófano.

Probióticos

Los probióticos son bacterias vivas que pueden tener un efecto positivo sobre la salud del huésped. El probiótico que se estudiará es Ecologic® BARRIER de Winclove Probiotics en Ámsterdam. Consiste en ocho tipos diferentes de bacterias. La investigación anterior por la Universidad de Leiden con este probiótico ha demostrado que puede reducir la sensibilidad para la depresión, que es causada probablemente por el probiótico que estimula la producción de serotonina.

El proyecto se lleva a cabo conjuntamente por:

- Lorenza Colzato (Institute for Psychological Research, Leiden)

- Peter Kirsch (Central Institute for Mental Health, Mannheim, Alemania)

- Martin Reuter (Universidad de Bonn, Alemania)

- Ana Rodríguez Moratinos (Universidad de Extremadura, España)
