Eating fish and other aquatic products can improve boys’ IQ
A study released by Sweden on Monday showed that eating more aquatic products such as fish in the daily diet can significantly increase boys’ IQ.
The study examined the IQ, language ability, and sense of space of 3,972 Swedish boys, then 15, in 2000. When these boys joined the army in 2003, they investigated these aspects again.
Studies have shown that boys who ate fish once a week at the age of 15 had a seven-point higher average on the IQ test after 3 years, while those who ate fish more than once a week were 12% higher.
The report’s co-author Maria Aaberg said in the statement: “There is a clear link between regular consumption of starch at the age of 15 and cognitive improvement at the age of 18.
In terms of language ability, children who ate fish once a week at the age of 15 were four percentages higher than children of the same age in tests after 3 years, while children who ate fish more than once a week were nine instances higher.
As for spatial comprehension, 15-year-old children who eat fish had 7 and 11 combined higher tests in the 18-year-old test, respectively.
