An adage I heard in childhood turns out to be true; fish is brain food. Package with Omega 3 fatty acids and vitamin D, eating fish twice a week is now recommended for good brain health and cognitive function. In 2006, I attended mind body medicine training sponsored by the BHI for Mind Body Medicine in Boston, Mass. and over fish for lunch one trainer suggested that Omega-3 and olive oil should be part of any healthy diet plan. She said there was research to prove it. One might wonder how many years it takes for us to learn what our mothers taught us.
Another recent study, reported this week in the NY Times, low blood levels of omega-3 fatty acids were associated with smaller brain volume and poorer performance on tests of mental acuity, even in people without apparent dementia.
In the analysis, published online in the journal Neurology, scientists examined 1,575 dementia-free men and women, whose average age was 67. The researchers analyzed the fatty acids of the subjects’ red blood cells. They used an M.R.I. scan to measure brain volume and white matter hyperintensities, a radiological finding indicative of vascular damage.
People in the lowest one-quarter for omega-3 levels had significantly lower total cerebral brain volume than those in the highest one-quarter, even after adjusting for age, body mass index, smoking and other factors. They also performed significantly worse on tests of visual memory, executive function and abstract memory than those in the highest one-quarter. There was no significant association with white matter hyperintensity volume.
“We feel that omega-3’s reduce vascular pathology and thus reduce the rate of brain aging,” said Dr. Zaldy S. Tan, the lead author and associate professor of medicine at the University of California, Los Angeles.
Few in the study were taking omega-3 supplements, Dr. Tan said. The main reason that some had higher blood levels of omega-3’s was that they ate more fatty fish. Examples of fatty fish are salmon, sardines, smelt, and anchovies.
Whether we believe it because of science or faith in the wisdom of mothers, fish is good for us and our brains.
