Children Eating Fish at least Once a Week Results in Better Sleep and Higher IQ.


Latest US research suggests that Children who eat fish at least once a week are more likely to sleep better and have higher IQ scores than those who eat fish less frequently or not at all.

Carried out by the University of Pennsylvania, the research follows Previous studies showed a relationship between omega-3s, the fatty acids in many types of fish, and improved intelligence, as well as omega-3s and better sleep. But they’ve never all been connected before.

For the research, a cohort of 541 9-to 11-year-olds, 54 percent boys, and 46 percent girls, completed a questionnaire about how often they consumed fish in the past month, with options ranging from “never” to “at least once per week.”

“This area of research is not well-developed. It’s emerging,” said Liu, lead author on the paper and an associate professor of nursing and public health. “Here we look at omega-3s coming from our food instead of from supplements.”

“It adds to the growing body of evidence showing that fish consumption has really positive health benefits and should be something more heavily advertised and promoted,” said Jianghong Liu “Children should be introduced to it early on,” Liu added.

The team also advised the whole family to increase their fish consumption together, little by little, even to just once per week. “Doing that could be a lot easier than nudging children about going to bed,” Raine said. “If the fish improves sleep, that’s great. If it also improves cognitive performance — like we’ve seen here — even better. It’s a double hit.”

The research results have been found published online in Scientific Reports, a Nature journal. For more latest news updates follow PressKS.
