Fish May Be Good for the Growing Brain

 Children who eat fish tend to sleep better and score higher on IQ tests, a new study has found.

Using self-administered questionnaires, researchers collected information on fish consumption among 541 Chinese boys and girls ages 9 to 11. Parents reported their children’s sleep duration, how often they awoke at night, daytime sleepiness and other sleep patterns. At age 12, the children took IQ tests.

Compared to the one-quarter of children who ate fish twice a month or less, those who had it twice a week or more scored an average of 4.8 points higher on IQ tests.

The study, in Scientific Reports, also found that the more fish a child ate, the fewer his or her sleep problems. There may be a chain of effects: fish consumption is associated with better sleep, and better sleep is associated with better cognitive performance. The study controlled for sex, parental education, maternal age at childbirth, breast-feeding duration and other factors.
