"Eating fish is good for your brain," is a widely circulated piece of dietary advice. So, how do scientists explain this?

Fish oil contains two high-concentration omega-3 fatty acids that are essential for normal brain development, and a diet rich in fish can also help us stay mentally sharp. A study showed that among the elderly, those who ate fish once a week experienced a 10% slower annual decline in cognitive skills over 6 years compared to their peers who didn't eat fish at all. Those who ate fish twice a week saw an even slower decline of 13%. Research from Harvard University also indicates that mothers who eat more fish during the 4th to 6th month of pregnancy have children who perform better on cognitive tests at 6 months of age.
It is widely believed that eating fish more than twice a week can indeed have a brain-boosting effect. Of course, when eating fish, it's important to avoid species that are easily contaminated and try to avoid those with high mercury levels, otherwise, the benefits may be outweighed by the risks.
