According to Finnish researchers, risk of dementia as well as of stroke considerably decrease by eating tuna and other fatty fish.
The lead author of the study, Jyrki Virtanen of the University of Kuopio in Finland told that ‘silent’ brain lesions that often become the cause of memory loss and dementia occurred less in those people who ate baked or broiled fish high in omega-3 fatty acids.
“The results of some previous studies have shown that fish and fish oil is helpful to avoid stroke, but this is the first study of its kind that examines the effects of fish on brain lesions in older people,” Virtanen further added.
Fish like salmon, mackerel sardines, herring and other foods like walnuts are rich with omega-3 fatty acids. These foods have also shown an anti-inflammatory effect and related to a lower risk of cardiovascular disease.
In the study, the Finnish researchers examined the cases of those 3,660 people who aged 65 and older and went through brains scans five years. The researchers found that the people who consume omega-3-rich fish more than two times a week had almost 26 percent lower risk of silent brain lesions.
While people who consume one serving per week were found with 13 percent reduced risk than those who didn’t include such sort of fish in their diets. The study has been published in the journal Neurology.
However, the researchers added that fried fish, in some people, did not appear to have the same benefits.
