A team of researchers at the Menzies Institute in Tasmania, Australia, spent five years tracking down 1,400 volunteers between the ages of 26 and 36. These volunteers record their diets every day, including all kinds of seafood, such as sea fish, shrimp and shellfish. At the same time, their mental health status was recorded in turn.
The study found that there is a strong correlation between the number of women eating fish and the chance of suffering from depression. The results showed that women who ate fish every other week had a 6% reduction in the risk of depression; women who ate more than twice a week had a 25% lower risk of depression than women who ate less than twice a week.
However, for men, there is no such good thing. The reason may be that men get more omega-3 fatty acids than women from other dietary sources, especially meat. According to Richard Marsh, director of the Institute of Food, Brain and Behavior, part of the human brain is made up of long-chain fatty acids of omega-3 fatty acids, which are common in fish oil.
Another reasonably plausible explanation is that omega-3 fatty acids may work with female sex hormones to boost brain health and thereby suppress the risk of depression.
This study proves that eating more fish is beneficial to women’s mental health. Of course, eating deep-sea fish is not only beneficial to women’s mental health, but also beneficial to the health of the brain. Experts recommend that people can eat deep-sea fish twice a week, such as mackerel, tuna, salmon and sardines.
