LOS ANGELES, Feb. 29 (UPI) -- A diet lacking in omega-3 fatty acids may cause the brain to age faster and lose some of its memory and thinking capabilities, U.S. researchers said.
Dr. Zaldy S. Tan, a member of the Easton Center for Alzheimer's Disease Research at the University of California, Los Angeles, said the study involved 1,575 dementia-free study subjects -- average age 67 -- who underwent brain scans and were given tests measuring mental function, body mass and omega-3 fatty acid levels in their red blood cells.
