Do Omega-3 fatty acids really make people more effective thinkers?
William Lassek, an epidemiologist at the University of Pittsburgh in Pennsylvania, and anthropologist Steven Gaulin of the University of California, Santa Barbara, set out to shed some light on this question.
As part of the Third National Health and Nutrition Examination Study, they studied 4,000 children between 6 and 16.
There were statistical controls to take into account the income levels, education, race, blood lead levels and siblings of the children’s families.
Four cognitive tests were given. Girls who ate more fish, and consumed more Omega-3 fatty acids, performed “significantly better.” They also score higher on IQ tests.
Boys who ate higher than normal amounts of Omega-3s did better as well, but not as well as the girls.
