Walnuts have always been considered as “Brain Food“, perhaps because its surface structure has a crinkly appearance like that of the brain. Due to this reason, they have been considered as a symbol of intelligence, leading to the belief that walnuts actually increase one’s intellect.
While this is not exactly true, recent scientific studies have proven that the consumption of walnuts does help in promoting brain function.
Eating just one ounce of walnuts a day (that’s about seven) may be all it takes to take advantage of their beneficial properties.
They have a significantly high concentration of DHA, a type of Omega-3 fatty acid. DHA has been shown to protect brain health in newborns, improve cognitive performance in adults, and prevent or ameliorate age-related cognitive decline.
One study even shows that mothers who get enough DHA have smarter kids. Just a quarter cup of walnuts provides nearly 100% of the recommended daily intake of DHA.
In a cross-sectional study that drew from a sampling of thousands of people in the United States aged 20 and older, those who ate more walnuts performed better on a series of six cognitive tests, according to new research from the David Geffen School of Medicine at The University of California, Los Angeles, led by Dr. Lenore Arab.
And cognitive function was consistently better no matter the person’s age, gender or ethnicity. The findings add to a growing body of research surrounding walnuts’ benefits on brain health.
A 2013 study published in The New England Journal of Medicine found that as little as one ounce of nuts per day could mean the difference between living to 80 and living to 90.
