Scientists recently learned that DHA (Docosahexaenoic Acid), an essential fatty acid, could be linked to human mental abilities. They studied several hundred adult volunteers, and the people who had higher blood levels of DHA showed better mental performance.1
Among the 280 healthy volunteers, the people with higher DHA levels received better scores on cognitive tests for nonverbal reasoning and mental flexibility, as well as working memory.
The authors of the study were also able to link vocabulary abilities to DHA levels.
DHA, an omega-3 fatty acid, is an essential nutrient that’s found in oily fish and is an important part of nervous system functions, according to Jane Higdon, a scientist from the Linus Pauling Institute.2
In fact, two scientists found that DHA could improve learning ability.3 In their study, Health Benefits of Docosahexaenoic Acid (DHA), scientists Lloyd A. Harrocks and Young K. Yeo indicate that this fatty acid influences learning ability by playing a role in cell signaling.
Other researchers indicate that cell signaling is made possible by phospholipids, the fats that help form cell membranes and contain fatty acids.4,5
In one study, scientists say: “Docosahexaenoic acid (DHA) is an important constituent of brain phospholipids and plays a role in maintaining structural and functional integrity of membranes.”6
So, by acting as a building block of brain cell membranes, DHA facilitates cellular signaling and helps with human mental performance.
