Can an average person achieve higher IQ?
Although IQ (Intelligence Quotient) does not always predict success in life, it remains a symbol of prominence.
For instance, Stephen Hawking and Albert Einstein both have high IQ level. Their intelligence made them famous.
But can an average person develop a higher IQ? How?
Recently, a group of researchers led by Dr. Jianghong Liu conducted a study to answer these questions.
The researchers followed more than 500 children in China aged nine to twelve.
The findings suggest that eating fish at least once a week was associated with higher IQ and better sleep.
In fact, the researchers found that those who eat fish once a week had five IQ points higher than those who don’t eat fish. In addition, eating more fish was also associated with fewer sleep disturbances.
Although the study on this topic is still in its infancy, it is the first evidence that links between omega-3 and higher IQ and better sleep.
Dr. Jianghong Liu said that “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.”
Eating fish is also helpful in reducing antisocial behavior. This is because an antisocial behavior is associated with lack of sleep.
Consuming ample amount of omega-3 may improve sleep. And better sleep may also reduce antisocial behavior.
Professor Adrian Raine, the co-author of the study added that “Lack of sleep is associated with antisocial behavior; poor cognition is associated with antisocial behavior. We have found that omega-3 supplements reduce antisocial behavior, so it’s not too surprising that fish is behind this.”
Eating fish does not only develop higher IQ but also better health. This made the other co-author of the study suggests the importance of fish consumption, especially among children.
“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,” said Professor Jennifer Pinto-Martin.
Professor Raine also supported the idea that children should eat fish regularly. “If the fish improves sleep, great. If it also improves cognitive performance – like we’ve seen here – even better. It’s a double hit.”
