Eating fish just once a week significantly slows down cognitive decline in older adults, according to a new study.
The decline in memory, mental speed and other cognitive abilities was slowed by 10 percent among people who ate one fish meal per week and 13 percent among those who ate two or more meals a week.
This is equivalent of being three to four years younger in mental age, report researchers from Rush University Medical Center.
Eating fish "may help preserve our thinking ability as we get older," said lead researcher Martha Clare Morris. The study is published in the Archives of Neurology.
