The researchers do not know why the affiliation was solely vital for fish consumption in Europe.
The research was additionally solely capable of present an affiliation between consuming fish and the chance for despair, not that consuming fish causes a decrease threat for despair, Li stated.
Nonetheless, Li thinks there could also be explanation why fish could impact despair.

This course of, known as a meta-analysis, makes an attempt to seek out constant patterns throughout a number of research.
Along with an total profit from fish in curbing despair, Li’s crew discovered a distinction between women and men. Particularly, the researchers discovered a barely stronger affiliation between consuming plenty of fish and lowered despair threat in males by 20 p.c. Amongst girls, discount in threat was 16 p.c, the researchers stated.
Simon Rego, director of psychology coaching at Montefiore Medical Middle/Albert Einstein Faculty of Medication in New York Metropolis, stated it is “unattainable to attract any definitive conclusions about direct trigger and impact” as a result of research’s design.
However, he added, “Whereas the precise means fish could stop despair is unknown, it is promising to study that despair could also be preventable for some folks by making easy modifications to their life-style, equivalent to by consuming extra fish.”
