A good night’s sleep and a higher IQ could be achieved by eating fish at least once per week — for children, at least. UPenn researchers analyzed the IQs, fish-eating habits and sleeping patterns of 541 Chinese children aged 9–11 years. They found children who ate fish weekly scored 4.8 points higher on IQ tests than those who never or seldom ate fish. Children who had fish sometimes had a 3.3 point advantage over those who didn’t or rarely ate it. Furthermore, children who ate fish at least once weekly had fewer sleep disturbances than those with lower fish intake, which the researchers say is an indicator of “better overall sleep quality.”
The research, published in the Nature journal Scientific Reports, also quizzed parents on their children’s quality of sleep, including how often they wake in the middle of the night and “daytime sleepiness.” It found, “increased fish consumption was associated with fewer disturbances of sleep… Lack of sleep is associated with antisocial behavior; poor cognition is associated with antisocial behavior,” explains study co-author Prof. Adrian Raine. “We have found that omega-3 supplements reduce antisocial behavior, so it’s not too surprising that fish is behind this.”
