Children who eat foods rich in omega-3 fatty acids like salmon and walnuts are more likely to score better on reading and memory tests, finds study.
The Oxford University study of 500 children indicates that it may help to add foods like salmon and walnuts to the table that are rich in omega-3 fatty acids, which are essential building blocks for a healthy brain.
After taking blood samples from the children between the ages of seven and nine, scientists found that levels of omega-3 fatty acids "significantly predicted" their ability to concentrate, and learn, the New York Daily News reported.
Presented at a conference in London last week, the study found that higher levels of omega-3, particularly the long-chain form of Docosahexaenoic acid (DHA), were associated with better reading and memory and fewer behavioral problems among the children examined.
Omega-3 fatty acids have been shown to play an important role in the brain's structure and cognitive function, in addition to heart health and the immune system.
Dietary sources of omega-3 include fatty fish such as sardines, mackerel, salmon and tuna as well as flaxseed oil and walnuts.
The study is published in the journal PLOS One.
