Eating fish every week may keep our brain more active during our older years. This is the conclusion of research conducted by the Rush University Medical Center in Chicago. The study found that older people who eat fish regularly have quicker and better memories. Over a lifetime of eating fish, people could be three to four years mentally younger in age. Lead researcher Martha Clare Morris said: “We found that people who ate one fish meal a week had a 10 percent slower annual decline in thinking.…People who rarely eat fish have a…faster decline in their thinking ability over time.”
Morris’s team collected information on the diets and memory loss of 6,158 people aged 65 and older. She concluded: “Eating fish may help to slow people’s decline in thinking ability as they age.” She thinks several fatty acids contained in fish may help the brain’s development. Eating fish has previously been associated with a lower risk of developing Alzheimer’s disease or having a stroke. Oily fish, like salmon and tuna, are a rich source of the acids. The report on the benefits of consuming fish appears in the October 10 online issue of the Archives of Neurology*.
