Omega-3 fatty acids study and brain aging

Trial data published in Neurology from 1500 dementia-free participants who underwent MRI scanning suggested that diet levels in omega-3 fatty acids could cause the brain to age faster and lose memory and thought abilities. Regular consumption of foods rich in omega-3 fatty acids can slow mental decline. People with DHA in the lowest quartile of the partipants had lower brain volume that those with higher DHA levels. Brain scans showed less blood supply in the brains of people with the lowest omega-3 fatty acids suggesting that DHA plays a role in promoting general health of blood vessels in the brain. see Neurology Vol 78 No 9, 658-664 "Red blood cell omega-3 fatty acid levels and markers of accelerated brain aging" Z.S.Tan et al.
