Eating fish in middle age could make you better at problem-solving and ward off memory loss.
A study of almost 2,200 Americans, mainly in their forties and fifties, measured the level of omega-3 fatty acids in their blood.
These come mainly from eating oily fish like salmon, mackerel, herring and sardines, although people can also get them from supplements.
The higher omega-3 level people had, the better they generally did in a test of complex reasoning, which is linked to being good at problem-solving in real life.
The three-quarters of people with the highest omega-3 level also had a larger hippocampus - the brain region linked to memory.
These people were likely to have eaten at least one serving (3g) of oily fish a week, according to researchers.

This larger hippocampus is likely to ward off dementia, as people have more brain cells to lose as they get older before suffering any memory loss.
Dr Claudia Satizabal, who led the study from the University of Texas Health Science Centre in San Antonio, said: ‘Eating fish, which is quite easy to do if you live by the coast in the UK, could help your brain age more healthily and protect against dementia.
