While access to quality dementia care may limit the devastating effect that the disease can have on loved ones, scientists say those who eat more fatty fish that contain omega-3 fatty acids could enjoy retirement living with less risk for the disease.
A study conducted in seven countries used interviews to establish th
e eating habits of the more than 15,000 participants, and in every country but India, researchers found that the more fatty fish one ate, the less likely one was to develop dementia.
The findings build on earlier studies, like one at the University of Kuopio in Finland where scientists combined dietary habit interviews with brain scans on more than 3,500 people.
They saw in the scans that those who ate fatty fish like salmon at least three times a week reduced their risk for lesions in the brain associated with dementia by more than one fourth; making a meal of omega-3-rich fish lowered the likelihood by 13 percent.
"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," said lead author Dr Jyrki Virtanen.
