A huge meta-analysis of 26 studies included more than 150,000 people. The researcher found that people eating a lot of fish have a 17% reduction in the risk of depression. Men and women profit in the same way.
The link between fish and reduced depression risk is strong. But still researcher don’t know the exact mechanism.
One possible explanation is that fish is rich in omega-three fatty acids. These “good” fats are known to be involved in the activity of certain neurotransmitters in the brain. Neurotransmitters are the way neurons (nerve cells) communicate. Serotonin is one of the neurotransmitters involved in the development of depression.
The researchers concluded: “Higher fish consumption may be beneficial in the primary prevention of depression. Future studies are needed to further investigate whether this association varies according to the type of fish.”
