If you do not treat your kid to fish once a week, it is time you did as kids who eat fish, at least, once a week are likely to score higher on IQ tests and experience sound sleep. A study published in the journal, Scientific Reports, the researchers at the University of Pennsylvania claim that omega-3 fatty acids found in fish may be the reason behind the same. Omega-3 fatty acids have previously been linked to intelligence and improved sleep.
The results suggested that kids who ate fish, at least, once a week scored 4.8 points higher on the IQ tests than the ones who never or seldom consumed fish. Children whose meals sometimes had fish included scored slightly more than three points. Also, , eating more fish was linked with better sleep.
The team of researchers, for the research, analysed the eating habits of 500+ boys and girls in China between 9 and 11 years. The kids were asked 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. The children also took a Chinese version of an IQ test that rates verbal and non-verbal skills called the Wechsler Intelligence Scale for Children – Revised. In addition, their parents had to answer questions about the child’s sleep quality including how long did kids sleep, how often they woke up in the middle of night, and whether they slept during the day.
Although the study was done on Chinese kids, researchers added that American kids are just as likely to benefit from eating fish but only if they are ready to modify their diet. The study cannot prove that eating fish accounted to higher IQ and better sleep, but they seem to be associated.
