Low levels of omega-3 in blood ‘ups’ risk of dementia and brain aging: Study

Researchers looked at 1,575 adults who averaged 67 years old and had no signs of dementia and had not had a stroke. They were given MRI brain scans and a battery of tests to measure memory and thinking abilities; they also had blood drawn to check the level of docosahexaenoic acid (DHA) or omega-3 fatty acids in their red blood cells. Those with the lowest levels of omega-3s showed signs of accelerated aging. They had lower brain volume, indicating shrinkage comparable to two additional years of aging. Compared with those with the highest blood levels of omega-3s, they scored lower on cognitive tests measuring such things as memory, problem solving, abstract thinking and multi-tasking.
