A study published in the journal Scientific Reports tells that eating fish at least once a week can dramatically improve children’s intelligence and also helps them sleep better. A study shows that the most regular consumers scored almost 5 points in IQ test which suggests that the old wives’ tale that fish makes you brainy is actually true. Researchers found seafood helps youngsters to sleep well, which boosts brain power.
The researchers from the University of Pennsylvania claimed that kids who ate fish once a week slept better and benefited from a higher IQ, by about four more points on average and omega-3 fatty acids found in fish may be the reason behind it.Omega-3 fatty acids have been linked to improved sleep and intelligence.
The study was done on Chinese kids between 9 and 11 years old, as per the researchers, American kids are just as likely to benefit from eating fish, but only if they are ready to modify their diet. For the research, researchers studied the eating habitat of around 500 boys and girls in China. The kids were told to complete a questionnaire about how often they ate fish in the past month, with option ranging from never to at least once a week. Then the kids also took a Chinese version of an IQ test that rates verbal and non-verbal skills which are known as the Wechsler Intelligence Scale for Children-Revised.
Children’s parents also had to answer questions about their child’s sleep quality. The result came that fish-eaters scored 4.8 more points and those who ate fish occasionally earned 3.3 more points than who never ate. Registered Nurse Jianghong Liu, lead author on the Paper said “This area of research is not well-developed. It’s emerging. Here we look at omega-3s coming from our food instead of from supplements.” According to the National Institutes of Health, there is some evidence indicating that omega-3s could help with rheumatoid arthritis.
