A study by researchers at the University of California in USA and published in the journal of Neurology suggests that people who follow a diet deficient in omega 3 may suffer in advance with the natural process of brain aging such as loss of memory, reasoning and cognitive abilities.
They analyzed 1575 individuals, men and women between 67 and 76 years old with no signs of dementia and made them go thru brain MRI and tests that measured mental function, body mass and levels of omega 3 in blood cells.
At the end of testing, the group of people who had the lowest levels of omega-3 had 25% less amount of the nutrient in the blood than the group that showed a higher presence of the fatty acid.
Those individuals with less omega-3 in the blood showed less brain volume on magnetic resonance and poor outcomes of tests of visual memory and executive function of the brain, such as problem solving and ability to think of several things at the same time.
This is definitely a good reason to include more Omega 3 in your meals daily! Omega 3 is present in salmon, sardines, tuna, flaxseeds, walnuts, chestnut, olive and canola oil, dark green vegetables and as supplements!
