Why eating fish once a week makes us smarter

Scientists from the University of Pittsburgh (USA) recommend eating fish once a week for brain health.

In early August, the University of Pittsburgh website published a conclusion from a group of scientists that eating baked fish has a very positive effect on brain health. The amount of omega-3 fatty acids contained in fish does not matter.

Scientists came to these conclusions during an experiment involving 260 people. The researchers found that participants who ate baked or fried fish at least once a week had more gray matter in areas of the brain responsible for memory and cognition. Interestingly, among the fish menu lovers there were more people with higher education. However, scientists were unable to find a connection between the level of omega-3 fatty acids and the development of these parts of the brain.

Previous research by university experts also shows that a healthy lifestyle - increasing physical activity, quitting smoking and fighting obesity - reduces the risk of developing Alzheimer's disease and other cognitive impairments. This is also facilitated by omega-3 fatty acids, which are found in large quantities in fish, seeds, nuts and some types of oils.

Thus, regular consumption of fish has a beneficial effect on brain function and cognitive abilities. Even one serving per week helps maintain brain activity and prevent age-related cognitive decline.
