The team previously observed that people with lower blood levels of omega-3 fatty acids were more apt to have a negative outlook and to be more impulsive, while those with higher levels typically were more agreeable and less likely to exhibit a sour mood.
In their latest study, Conklin and colleagues set out to see whether the volume of gray matter in the brain, especially in areas related to mood, was proportionally related to the amount of omega-3 fatty acid consumed.
They asked 55 healthy adults about their average intake of omega-3 fatty acids and used MRI bran scans to determine gray matter volume.
As the researchers theorized, the higher the intake of omega-3 the larger were the volumes of gray matter in areas of the brain associated with mood and regulation of emotion.
