Based on research published in the American Journal of Preventive Medicine, people who have a grilled fish mengosumsi gray matter (which is responsible for memory) in regions of the brain, the wider, ie 4.3 percent and cognition (14 percent) than their who do not eat fish regularly. They are also more likely to have higher education than those who do not regularly eat fish.
"Our study shows that people who eat a diet that includes fish grilled, not fried, has a larger volume of brain regions, which is associated with memory and cognition," says senior investigator, James T. Becker, Ph.D., who is also a professor of psychiatry at the University of Pittsburgh School of Medicine.
However, according to the researchers, no association was found between the difference (volume) of the brain and omega-3 content.
"We did not find an association between omega-3 levels and changes (volume) of the brain. It's a bit surprising to us, "Becker said as quoted by the official website of University of Pittsburgh School of Medicine, also reported Reuters.
"This leads us to the conclusion that we are entering a more general set of lifestyle factors that affect the health of the brain, where the diet is just one part," he added.
According to Dr. Becker, compared to biological factors, lifestyle factors, in this case, eating fish, contribute to the structural changes in the brain.
"Lifestyle factors may be responsible for better brain health, and this may prevent or delay cognitive problems that may develop later in life," he said.
Effects of antioxidants in omega-3 acids, which are found high amounts in fish, seeds and nuts and oils have also been known to be associated with improved health, especially the health of the brain.
In this study, the researchers analyzed data from 260 people about their dietary intake, based on the high-resolution brain MRI and cognitively normal in two times during their participation in the Cardiovascular Health Study (CHS).
The study starts from 1989 through the next 10 years is to identify risk factors for heart disease in people aged over 65 years.
"CHS study participants answered a questionnaire about their eating habits, such as how much fish they eat and how to cook it," said the team leader, Cyrus Raji, MD, Ph.D.
"Baked fish has omega-3 content is higher than fried fish, because the fatty acid is destroyed in high heat when frying, so we made this into consideration when researching their brain scans," he added.
Several studies have estimated, lifestyle changes, such as reducing smoking, physical inactivity and obesity can reduce cases of Alzheimer's disease and other conditions kongnitif disorders in the elderly.
According to Dr. Becker, scientists estimate in 2040, more than 80 million people will suffer from dementia. This in turn can be a substantial burden families and increase health care costs.
