Salmon

The amazing health benefits.
Many researchers consider DHA to be the most important fat found in the human brain, and the unusual concentration of this omega-3 fatty acid in salmon helps explain the research-documented benefits of salmon and omega-3 fish intake for thinking and the decreased risk of certain brain-related problems that accompanies omega-3 fish consumption. Intake of omega-3s and omega-3 containing fish is associated with decreased risk of depression, decreased risk of hostility in some studies of teenagers, and decreased risk of cognitive decline in older persons. Some studies have shown an association between IQ and omega-3 intake, and also between IQ and intake of omega-3 fish.

Especially interesting in this area of fish intake, DHA, and brain function is the relatively recent discovery of protectins. Protectins are special compounds made from DHA and preliminary research studies have shown them to have a potentially important role as anti-inflammatory regulatory molecules, especially when produced by nerve tissue. (When protectins are produced by nerve tissue, they are typically called "neuroprotectins.") Researchers have speculated that at least some of the brain-related benefits from omega-3 fish intake may be due to conversion of the DHA in these fish to protectins that can help prevent excessive inflammation.
