Fish that is rich in Omega-3 fatty acids is especially associated with a healthier heart, a lower risk of developing Alzheimer’s disease, better cognitive functions and more beautiful skin and hair.
A new study now looks deeper into the benefit of a diet rich in fish and shows that it can be linked to a much lower chance of becoming depressed. This theory is not entirely new, but more evidence is always useful, given the fact that there are about 350 million people on the globe who suffer from depression.
A team of researchers from the Medical College of Qingdao University, in Shandong, China, looked at 26 studies comprised in 16 articles. The studies were conducted by researchers all over the world and they involved over 150,000 people.
The findings revealed that the risk of developing depression is much lower for those who consume a lot of fish, even if recommendations were not given by the experts, so it remains uncertain what “a lot” means or what type of fish should be eaten.
Thus, it was shown that men who eat lots of fish lower their chance of depression by as much as 20 percent, while women decrease their risk of becoming depressed by 16 percent.
A reason for this is that the omega-3 fatty acids that fish usually contains might lead to modifications of the dopamine and serotonin levels, which are known to be involved in depression. Moreover, the high content of nutrients, vitamins and minerals could also have a role in keeping the person away from depression, as it is known that healthy food keeps people happy.
Other health experts have associated food with depression, recommending that people who are at risk eat a lot of fruit, legumes, vegetables and less sugar and complex carbohydrates.
According to lead study author Professor Dongfeng Zhang, more studies are needed to confirm the theory but the research is, nevertheless, an important starting point for health experts, when it comes to making useful recommendations to their patients.
