Selenium is an essential micronutrient that can become toxic when ingested in high concentrations The human being can obtain Se through the consumption of food, dietary supplements, water and exposure to ambient air The food source is the most abundant and the main contributor to the daily intake of Se in Fish is one of the best sources of Se, and the Portuguese Mackerel is one of the most important and abundant species in Portugal It is rich in several vitamins and Se, due to being a predator The work presented integrates part of the first task of the project Newfood 4 thought that aims at the prevention of cognitive decline through nutrient combination. The aim is to study of the influence of seasonality in the levels of Se in Mackerel samples collected throughout the year. With the exception of May, Se content in mackerel remained constant throughout the year The high Se content found in May samples may be related to mackerel ´ s spawning season and feeding habits However, further studies are needed to confirm these preliminary conclusions, namely studying the Se content monthly for several years
