Clinical studies have revealed that depression is accompanied by impaired brain function and cognitive performances or neurodegenerative processes. Moreover, accumulation of oxidative damage has been implicated in aging and various neurological disorders. This chapter aims to integrate the current knowledge on the relation between brain and diverse alterations in nutrition. The mammalian brain is a lipid-rich organ, where lipids content in gray matter is 36–40% lipid. However, the regulation of cholesterol transport from astrocytes to neurons still remains unclear, among other things. In addition to that, micronutrient status can affect cognitive function at all ages. Vitamin deficiency could influence memory function, and might contribute to cognitive impairment and dementia. |
