Its emerging," said Liu, lead author on the paper and an associate professor of nursing and public health. The researchers also want to add to this current observational study to establish, through randomized controlled trials, that eating fish can lead to better sleep, better school performance and other real-life, practical outcomes. Children are sensitive to smell.This work, conducted by Jianghong Liu, Jennifer Pinto-Martin and Alexandra Hanlon of the School of Nursing and Penn Integrates Knowledge Professor Adrian Raine, reveals sleep as a possible mediating pathway, the potential missing link between fish and intelligence.

The findings have been published in the journal Nature.Previous studies showed a relationship between omega-3s, the fatty acids in many types of fish, and improved intelligence, as well as omega-3s and better sleep."Given the young age of this study group, Liu and colleagues chose not to analyze the details participants reported about the types of fish consumed, though they plan to do so for work on an older cohort in the future.For the moment, the researchers recommend incrementally incorporating additional fish into a diet; consumption even once a week moves a family into the "high" fish-eating group as defined in the study.Washington: Eating fish at least once a week results in better sleep and higher IQ in children, suggests a study."Introducing the taste early makes it more palatable," Pinto-Martin said. "It really has to be a concerted effort, especially in a culture where fish is not as commonly served or smelled. If it also improves cognitive performance -- like weve seen here -- even better. .."It adds to the growing body of evidence showing that fish consumption has really positive health benefits and should be something more heavily advertised and promoted," she said."Doing that could be a lot easier than nudging children about going to bed," Raine chinese fish tanks said
