Abstract Clinical studies revealed that depression is accompanied by impaired brain function and cognitive performances or neurodegenerative processes. This could be associated to diverse alterations in the nutrient intake. Micronutrient status can affect cognitive function at all ages. Vitamin deficiency could influence memory function and might contribute to cognitive impairment and dementia. Deficiency of vitamin A, folate, vitamins B6, B12, and minerals as Fe and Zinc are associated to prevalence of depressive symptoms according to several epidemiological studies. The adequate intake of fruit, nuts, vegetables, cereals, legumes or fish can prevent the depletion. High dietary intake of saturated fat and low intake of vegetables may be associated with increased risk of Alzheimer disease. Supplementation of diets with omega-3 has been shown to have positive effects on cognitive function. The biochemical and molecular mechanism of these alterations of normal brain function has been described.
