Eat fish and avoid brain damage caused by pollution.

A detailed survey found that regular consumption of salmon, gray and other greasy fish, especially in the elderly, can protect the brain from air pollution damage. Details are included in the latest issue of the Journal of Neurology.

This is because all oily fish are rich in omega-3 fatty acids, which on the one hand keep the heart strong, on the other hand reduce the body's internal inflammation and remove the waste products that accumulate in the brain. Do out If the amount of mercury and lead in the atmosphere is damaging the brain, omega-3 fatty acids have the ability to reduce it.

The study was conducted by a obstetrician and gynecologist at Columbia University. According to him, the toxins that accumulate in the brain can be eliminated with omega-3 fatty acids. Thus a profound link between diet and mental health has been discovered.

Air pollution contains innumerable toxic compounds, including heavy metals. The study looked at air pollution and diet in areas over the age of 70 for women. Experts were surprised to find that women who had low levels of omega-3 fatty acids had more shrunken brains than other women.

During further research, the experts also looked at the amount of fish each woman ate weekly, the amount of fatty acids in her blood, and the air pollution around her home. This process continued for three consecutive years. In the meantime, brain scans of all the participants were taken in between, in which the hippocampus in particular was noted. This area is the center of our memory and the white matter in it serves to send and receive brain signals.

It was found that eating fish maintained the amount of white matter (white matter) in the brain, which helped prevent the destructive effects of air pollution.

In this sense, there is a strong link between mental health and diet, and thus oily fish can help protect the brain from the toxic effects of air pollution.
