The Claim
Individuals in the highest tertile of fish intake score 1.9 points higher on the selective reminding test for verbal memory after 4 years compared to individuals in the lowest tertile of fish intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat the most fish over four years score 1.9 points higher on a verbal memory test than people who eat the least fish.
See the scientific wording
Higher fish intake is associated with better verbal memory performance, with individuals in the highest intake tertile scoring 1.9 points higher on the selective reminding test after 4 years compared to those in the lowest tertile.
Fats from fish enter the brain and help build and repair connections between nerve cells, while also calming harmful inflammation that damages those connections. This keeps the brain better able to store and recall words and language.
What the research says
1 studyMen who ate more fish remembered about 2 more words on a memory test after four years compared to those who ate less fish — and the study found exactly that.
