Fish consumption can improve IQ
Children who ate fish at least once a week on average improved sleep quality. In addition, their IQ test scores are also higher than children who rarely or never eat fish. Researchers found that children each week ate their IQ test score scores 4.8 points higher than those who "rarely" or even "never" consumed fish. Children who covered 54 percent of men and 46 percent of women were surveyed about their fish consumption in the past month. Meanwhile, parents were asked about the sleep quality of children at night and day. The boys and girls were also asked to undergo an IQ test to test their verbal and non-verbal abilities.
