omega-3
fatty acids in the fish.The findings, published in the American Journal of Preventive Medicine, are further evidence that lifestyle factors are good for brain health later in life, according to a report published on
8 5
, in the Journal of Preventive Medicine.. James Becker, a professor of psychiatry at the University of Pittsburgh School of Medicine, said scientists expect more than
,800,000 people to develop dementia by
2040

, a huge burden on families and aincrease in medical costs. Some studies suggest that lifestyle changes, such as increased activity and lower rates of smoking and obesity, can help reduce the risk of Alzheimer's disease and other cognitive impairments in old age.

oxidation offatty acids also helps improve health, especially brain health, while fish, seeds, nuts and certain types of oil contain more
omega-3
fatty acids.Our study shows that people who
eat grilled fish more often than fried fish have larger areas of the brain
associated with memory and cognition,"Dr. Becker said. The conclusion is that we are uncovering a broader range of lifestyle factors that can affect brain health, and diet is only part of that. 's lead researcher, Cyrus Raj, M.D., and a team of researchers analyzed data from
260,
people who provided information about their diets, underwent high-resolution brain MRI tests, and were all cognitively normal when they participated in a cardiovascular health study. The study began in

1989 to analyze risk factors for heart disease in
65-year-olds over
years of age." the participants answered questions about eating habits, such as how much fish they would eat, how they cooked, and so on. Raj said, "Compared to fried fish, grilled fish has a higher
omega-3
fatty acid content, because the high temperature of frying destroys
omega-3
fatty acids, so we took this factor into account when we scanned their brains."researchers found that people who ate grilled fish at least once a week had more grayscale in their brains responsible for memory and cognitive areas, and were more likely to receive a college education than those who ate fish less often. But the study did not find a link between
differences in the blood
high and low levels of fatty acids."This suggests that lifestyle factors (in this study, taking fish as an example) rather than biological factors have an effect on structural changes in the brain," Dr. Becker said. ”
