4. Tuna and some other fish
Some fish are good for your brain, but mercury-rich fish can have a negative impact on your cognitive function. Fish in this category include tuna (fresh or frozen), king mackerel, orange farmer, swordfish, shark, caribbean, escolar and canned white tuna.
Unfortunately, fish are very sensitive to mercury because it is abundant in the ocean. They absorb it through the gills and can store it in the long run. Since mercury levels may vary depending on your location, it is best to consult your local food safety and security agency to find out which fresh fish are rich in mercury to avoid.
