Swedish researchers found that among nearly 5,000 15-year-old boys they surveyed, those who ate fish more than once per week tended to score higher on intelligence tests three years later.
Researchers believe that the omega-3 fats found in fish — particularly oily fish like salmon, mackerel and, to a lesser extent, albacore tuna — are important to early brain development and to maintaining healthy brain function throughout life.
The new study appears to be the first large-scale one to look at the effects of fish on teenagers’ intelligence, lead researcher Dr. Maria Aberg, of Goteborg University, told Reuters Health.
