Study finds weekly fish consumption linked to better sleep, higher IQ
Analyzing these data points, the Penn team found that children who reported eating fish weekly scored 4.8 points higher on the IQ exams than those who said they “seldom” or “never” consumed fish.
Children who eat fish at least once a week sleep better and have IQ scores that are 4 points higher, on average, than those who consume fish less frequently or not at all, according to new findings from the University of Pennsylvania, Philadelphia, Pa.
Previous studies showed a relationship between omega-3s and improved intelligence, as well as omega-3s and better sleep. But, they’ve never all been connected before.
