For those who suffer form – or are afraid of – memory problems, there is good news coming from a Swedish study which has found fish consumption may improve cognitive skills.

The study examined fish consumption in teenage Swedish boys at age 15, and found that those who ate fish at least once a week had higher cognitive skills at age 18 than those who ate it less frequently.

In fact, the former group had combined intelligence scores that were, on average, nearly 11 percent higher than those who ate fish less than once a week.

“There are a number of studies linking omega-3 EPA/DHA found in oily fish to thinking, reasoning, and remembering abilities in infants and the elderly,” says Jon Getzinger of Ocean Nutrition Canada.

However, he adds that given that it can be challenging for young children and teens to eat fatty fish, as many of them do not like the taste, omega-3 EPA/DHA-enhanced foods “are an easy way to incorporate this nutrient into their diets.”

Omega-3 essential fatty acids are also available at health stores in the form of nutritional supplements.
