Eat Fish, Help Your Brain!

(Ivanhoe Newswire)– If your diet is lacking in omega 3′s, you may be putting your brain at risk for memory loss, and speeding up aging.

“People with lower blood levels of omega-3 fatty acids had lower brain volumes that were equivalent to about two years of structural brain aging,” Zaldy S. Tan, MD, MPH, study author, was quoted as saying of the Easton Center for Alzheimer’s Disease Research and the Division of Geriatrics, University of California at Los Angeles.

The study consisted of 1,575 participants with an average age of 67, who did not show signs of dementia and had MRI brain scans done. The participants were also given tests that measured mental function, body mass and the omega-3 fatty acid levels in their red blood cells.

What the researchers found was that individuals whose DHA levels were among the bottom 25 percent of the participants had lower brain volume compared to those who had higher DHA levels. Furthermore, participants with levels of all omega-3 fatty acids in the bottom 25 percent also scored lower on tests of visual memory and executive function, such as problem solving and multi-tasking and abstract thinking.
