Researchers from Columbia University in New York, have recently shown that Omega-3 fatty acids from fishes can fight inflammation and maintain brain structure in ageing brains.
On Wednesday, the 15th of July 2020, American academy of neurology, published a research article by author Ka. He, M.D., Sc.D., of Columbia University in New York, proving that higher levels of fish consumption can preserve the brain from air pollution.
Researchers also discovered that among older women who lived in areas with high levels of air pollution, those who had the lowest levels of omega-3 fatty acids in their blood had more brain shrinkage than women who had the highest levels.
Previous researchers have shown that fishes are excellent sources of omega-3 fatty acids and they are easy to add to the diet. This research has found out that omega-3 fatty acids can reduce brain damage caused by neurotoxins like lead and mercury. So we explored if omega-3 fatty acids have a protective effect against another neurotoxin, the fine particulate matter found in air pollution.
During the research, emphasis was placed on age, education and frequency of smoking, after adjusting for age, education, smoking and other factors that could affect brain shrinkage, researchers found that women who had the highest levels of omega-3 fatty acids in the blood had greater volumes of white matter than those with the lowest levels.
