Eating fish is good for kids IQ’s.
A new study from the University of Pennsylvania found that children who eat fish at least once a week boosted their intelligence test scores and the quality of their sleep.
But they’ve never all been connected before, according to Penn researchers who focused on omega- 3 S coming from food, not supplements.
“This area of research is not well-developed. It’s emerging,” said Jianghong Liu, lead author on the paper and an associate professor of nursing and public health, in a university release.
Findings are based on a group of 541 9- to 11-year-old boys and girls in China.
Subjects reported how often they had consumed fish in the past month. Options ranged often (at least once per week), to occasionally (2-3 times per month), to seldom or never (less than 2 times per month).
Youngsters also took an IQ test that examines verbal and non-verbal skills such as vocabulary and coding. Parents completed a questionnaire about their kids’ sleep habits.
After accounting for parents’ education and jobs, marital status and the number of kids in the home,
researchers found that kids who eat fish at least once a week sleep better and have IQ scores that are 4.8 points higher, on average, than those who consume fish less frequently or not at all.
Increased fish consumption was associated with “fewer disturbances of sleep, which,” researchers said, “indicates better overall sleep quality.”
The findings have important implications when it comes to promoting healthy diets for kids and adolescents.
