Eating fish is good for the development of intellectual abilities and the child’s sleep. To such conclusion scientists from the University of Pennsylvania.
The main focus of the study was done to study the effects of polyunsaturated fatty acids omega-3 on the body of the child. It is known that they are contained in fish in large quantity.
The study involved 541 children (boys and girls) from 9 to 11 years. Children live in China. The analysis was conducted on the basis of a survey of children regarding the frequency of eating fish. The answers were the most different: from “at least once a week” to “less than 2 times a month.” Next, subjects were tested for IQ, and parents of the subjects interviewed regarding the sleep quality of their children.
It was found that children who ate fish at least once a week, IQ by 4.8 points higher than those who ate it less frequently or did not eat. In addition, the “fish lovers”, scientists have recorded fewer violations of sleep, than those who rarely eat fish.
The results of the analysis are important in formulating strategies of healthy nutrition for children, but scientists believe that research should continue. Now they intend to study “the mechanisms by which omega-3 fatty acids can help to improve neuroreplete and cognitive function”.
