Looks like Jeeves is proved right once again.
Eating fish may thwart silent brain damage.
Older adults who regularly eat fish may have a lower risk of subtle brain damage that contributes to stroke and dementia — as long as the fish isn’t fried — researchers reported Monday. In a study that followed 3,660 adults age 65 and older, Finnish researchers found that those who ate more fish were less likely to show certain “silent” brain infarcts — tiny areas of tissue that have died because of an insufficient blood supply — on an MRI scan. The tissue damage is considered silent, or “subclinical,” because it causes no obvious symptoms and can only be detected through brain scans. It can, however, raise a person’s longer-term risk of having a stroke or developing dementia. Among older adults in the current study, those who said they ate tuna and “other” baked or broiled fish at least three times per week were one-quarter less likely than those who rarely ate fish to have subclinical brain infarcts at the study’s start. Fish eaters also tended to be less likely to develop new infarcts over the next five years. No such benefits were linked to consumption of fried fish, however, the researchers report in the journal Neurology.
