Omega-3 Found to Increase Brain’s Gray Matter  
 
Omega-3 fatty acids, found in fatty fish such as salmon, are associated with increased gray matter volume in areas of the brain typically linked to mood and behavior according to new research.

The study’s results were presented March 6, 2007, by Sarah M. Conklin, Ph.D., postdoctoral scholar at the Cardiovascular Behavioral Medicine Program in the department of psychiatry at the University of Pittsburgh (Pitt; PA, USA; www.pitt.edu), at the American Psychosomatic Society’s annual meeting, held in Budapest, Hungary.

While this finding suggests that omega-3s may promote structural improvement in areas of the brain related to mood and emotion regulation--the same areas where gray matter is decreased in individuals who have mood disorders such as major depressive disorder--investigators noted that more research is needed to determine whether fish consumption actually causes changes in the brain.
