Scientists have learned which product helps to increase intelligence!Scientists from the University of Pennsylvania have proven that eating fish increases the intelligence and improves sleep. The study was conducted among children, its results were published by the portal Eurekalert.
Earlier studies have shown the effect of omega-3 fatty acids in fish on mental activity, but the relationship between increased intelligence and improved sleep has not been studied enough, the authors of the study believe.
The study involved 541 children from China aged 9 to 11 years - 54% were boys, 46% were girls. They answered the question of how often they eat fish, and then passed the test for intelligence. Simultaneously, their parents assessed the quality of sleep in children, answering the relevant questions of scientists.
According to the test results, it was found that children who ate fish at least once a week had fewer sleep disorders. In addition, they on average scored in the tests for IQ by 4.8 points more than their peers, who use this product rarely or never.
According to scientists, the results of the study support the idea that children should be given more fish. A child can take it for food, starting from the age of two, and the earlier "introduce" the child to this product, the better it will perceive it to taste. "Children can smell good, if they are not used to it, they can avoid eating fish," explained one of the authors of the study, Jennifer Pinto-Martin.

I grew up eating fish. And seems the article is right. I have no sleep disorders and love sleeping 8 to 10 hours daily. Plus sometimes even had above a 4.0 in my studies xD

I don't really like this study at all, far too many variables involved in the development of intelligence, the largest being the random chances of genetics which are influenced partially by parental IQ, and partially by environmental factors surrounding gestation and early development/nutrition, which is what this study is attempting to investigate - but in a flawed manner. I don't believe these results are reproducible at all as the sample size is very small, 541 children is nowhere near the amount you'd need to avoid the influence extraneous variables - of which there are a multitude of for IQ, anything below a sample of 20,000 that accounts for parental IQ, geographic location, education quality, and economic status has me highly doubtful. Beyond all this, the measured gain of 4.8 IQ points is not statistically significant given the potential influence of conflicting variables such as the ones mentioned earlier (only to name a few). Also, in an age where sleep quality can be empirically derived via modern sleep tracking apps on phones, assessing sleep via one's own opinion is inexcusable. It gets worse though - the parents assessed the sleep quality of their children. I honestly don't even know what these researchers were thinking with this process, I'd be very surprised to see this make it past peer review anywhere. Omega-3 fatty acids amongst a variety of other beneficial nutrients are found in fish and could help in development of IQ, although a much better study needs to be conducted to find out the extent. Why not ask what type of fish was eaten, and how it was prepared? These two questions could have an impact on the types of nutrients received when different types of fish are eaten and the detriments of certain types of preparation (unhealthy fats from frying, bacteria+mercury from uncooked sushi, or less detriments from baking, etc.) could have an influence on nutrition as well. This is only one type of meal these children are eating though, and assuming they don't eat fish 3 times a day (hopefully), information on the other meals is necessary to avoid the influence of the other meals from affecting sleep and IQ, although a statistically significant increase in fish as compared to benchmark data on children dietary habits for that specific region of China would be important in ruling this out. Measuring fish consumption amount on a 1-10 scale is really not cutting it. I wouldn't even take a suggested correlation from this study, it's far too weak in it's methods. Still eat fish though of course, a bad study doesn't mean it's unhealthy, the mechanism this study attempted to prove is still real, but evidently not convincingly proven yet.

How would you conduct this study? Or what exactly would you do differently? |

A much larger sample size, around 20,000 ideally with anything below 10,000 undesirable, and anything below 5,000 useless, with sleep monitoring done through a selected phone app consistent with all participants. The participants log all meals given to children (ideally through the same app that records sleep) and tick a box for preparation type, while they also record IQ twice yearly, for 2 years. The selection of participants is the most important part, most importantly they must be from the same income level which is ideally middle class to avoid the larger prevalence of conflicting variables in lower incomes, and a shared geographic location which is defined by the type of land development (urban/suburban/rural), the province, and the dialect spoken. The second most important variable is education quality, which would need to either be weighted or constant with a smaller sample size. The variation in initial IQ is controlled by comparing multiple IQ scores over time. Distributing this study through schools of similar education quality levels in the same metropolitan area would be ideal for a study like this. An area where regular IQ testing is common or easily available would help, although a norm referenced fluid intelligence test could possibly be provided through an app which sacrifices accuracy for the sake of sample size, and would allow for a large amount of data collection. Distributing this through a custom made app would actually allow for longer term studies, and a myriad of potential papers to be written on the affects of any of the food families and their affects on IQ and sleep, as by running the data through a program like MATLAB one can just run a find function for every data point above a certain point on the prevelance of a certain food family, and find correlations for any food family between their corresponding IQ and sleep quality variables by mapping them to a line graph. Would be a great study, but I'm not sure it's necessary given our current knowledge of the flynn effect, nutrition, and environmental factors in IQ stemming from their interaction with neurogenesis+neuroplasticity processes.
