A team of researchers led by Dr. Zaldy S. Tan, a visiting professor at the University of California, Los Angeles (UCLA) found so much benefits of eating a diet rich in omega-3 fatty acids including oily fish such as salmon. Researchers believe oily fish could protect against premature aging of human brain and memory problems, especially when reaching the middle age group. On this age group, researchers found most people suffered from aging of brain and memory issues. The study is being published by the journal Neurology.
The Westwood, California-based University’s researchers applied samples of 1,575 people at age group of 58 to 76. Those in the samples must go thru tests including MRI brain scans, blood tests, and several types of mental-function tests. Researchers found men and women with the highest levels of omega-3s performed much better in visual memory and abstract reasoning tests. While men and women who had lowest levels of omega-3s had smaller brains and scored poorer on a series of tests such as memory and cognitive tests.
