Past studies have shown that people who take in the recommended amounts of omega-3 fatty acids may be able to reduce their risk of heart attacks and strokes, according to the Mayo Clinic.
Now, new research reveals that elderly people who consume food rich in omega-3 fatty acids and vitamins may be able to stay sharp in their old age. In the study, scientists from Oregon Health and Science University and Oregon State University’s Linus Pauling Institute worked with 104 people with an average age of 87.
Scientists tested 30 different nutrient biomarkers in the participants’ blood, while 42 of them underwent magnetic resonance imaging scans. Based on blood nutrient levels and other data, the scientists found a connection between cognitive ability and high levels of vitamins B, C, D, E and healthy oils.
"The vitamins and nutrients you get from eating a wide range of fruits, vegetables and fish can be measured in blood biomarkers," said Maret Traber, principal investigator at the Linus Pauling Institute and co-author of the study. "I’m a firm believer these nutrients have strong potential to protect your brain and make it work better."
Individuals who are curious about what impact their diet is having on their cognitive abilities may want to take an IQ test and find out.
