ABSTRACT

La nutrición ha sido relacionada ampliamente con el proceso fisiológico del envejecimiento. Varios nutrientes, como ciertos tipos de grasa de la dieta y diversos antioxidantes, han demostrado poseer efectos positivos en enfermedades relacionadas con la edad. El tipo de grasa de la dieta afecta a la estructura y función mitocondrial, así como a su susceptibilidad al estrés oxidativo, todos, factores implicados en el envejecimiento. La presente revisión trata de resumir los estudios realizados por nuestro grupo de investigación en los últimos 10 años empleando aceite de oliva virgen, aceite de girasol o aceite de pescado como fuente de grasa insaturada de la dieta en relación con un modelo de envejecimiento en rata (AU9


Nutrition has been largely related to the physiological ageing process. Several nutrients, such as certain types of dietary fat and various antioxidants have been shown to have positive effects on age-related diseases. The type of dietary fat affects mitochondrial structure and function, as well as its susceptibility to oxidative stress, all factors involved in ageing. The present review aims to summarise the studies conducted by our research group in the past 10 years, using virgin olive oil, sunflower oil, or fish oil as a source of unsaturated fat diet relative to a rat model of ageing (AU)
