A new study by UCLA researchers shows that a diet lacking in omega-3 fatty acids, which are commonly found in fish, may cause your brain to age faster and lose some of its memory and thinking capabilities. The research demonstrated that people with lower levels of omega-3 fatty acids have lower brain volumes — equivalent to approximately two years of structural brain aging.
Fish: Good and good for you The 1,575 dementia-free study subjects (average age 67) underwent MRI brain scans and were given tests measuring mental function, body mass and omega-3 fatty acid levels in their red blood cells. Omega-3 fatty acids include the nutrients docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Researchers found that those whose DHA levels were in the bottom 25 percent had lower brain volumes than those with higher DHA levels. In addition, those whose levels of all omega-3 fatty acids were in the bottom 25 percent scored lower on tests of visual memory and executive function, including problem-solving, multi-tasking and abstract thinking.
