"Consuming fish like tuna, salmon or mackerel three times a week reduces harmful brain lesions which can trigger Alzheimer's disease and stroke.
Researchers claim it could cut the risk of brain problems by 26 per cent.
But the study found that health benefits dramatically reduce if the fish is fried rather than baked or steamed.
Jyrki Virtanen, who led the study at the University of Kuopio in Finland, said: "While eating tuna and other types of fish seems to help protect against memory loss and stroke, these results were not found in people who regularly ate fried fish.
'More research is needed as to why these types of fish may have protective effects, but the omega-3 fatty acids would seem to have a major role.""
