A weekly consumption of fish is associated to a better sleep and higher IQ level in case of children from age of nine to eleven years old, if compared to that of the children who don’t eat fish or less frequently. The study is discovered by the University of Pennsylvania and published in the Scientific Reports this week.
Earlier research had disclosed the link between better sleep and fatty acids i.e. omega 3s which is found in fish, as well as improved intelligence in children and omega-3s. But all these links have never been connected together before.
Jianghong Liu, Alexandra Hanlon and Jennifer Pinto Martin from The University of Pennsylvania School of Nursing and Adrian Raine, a professor from the Penn Integrates Knowledge conducted the research that revealed sleep as a major mediating possible pathway, which is the potential missing connection between intelligence and fish consumption.
Leading professor, Jianghong Liu said in a statement that, “This area of research is not well-developed. It’s emerging. Here we look at omega-3s coming from our food instead of from supplements.”
Jennifer Pinto Martin is the executive director of the Center for Public Health Initiatives of the Penn University and also Viola MacInnes/Independence Professor of epidemiology and nursing at Penn Medicine, who holds strong potential of involvement in the research.
Pinto Martin said that, “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. Children should be introduced to it early on.”
