Fish really is brain food for children, boosting their intelligence and helping them sleep better, scientists say. US researchers found that children aged nine to 11 who ate fish at least once a week scored almost five points higher in IQ tests compared to those who “seldom” did. Fish is considered an important part of a healthy diet, being both low in saturated fat and rich in protein, vitamins and minerals. Oily fish, such as salmon and mackerel, is also a good source of omega-3 fatty acids, which are essential for brain development and also thought to reduce inflammation of the brain, cardiovascular system and other cells. The study of more than 500 children asked how often they had consumed fish in the past month. They then took part in an IQ test. Those who ate fish at least once a week scored 4.8 points higher than those who never eat it. Even those whose meals sometimes included fish scored 3.3 points higher. Those who ate fish at least weekly also had fewer sleep disturbances and “better overall sleep quality” than those with a lower intake. The latest findings were published in Scientific Reports.
