During pregnancy the mothers must pay attention to food intake. What women consumed a major impact on the health and intelligence of the fetus.
In a recent study of pregnant women found eating fish such as tuna turned out to affect cognitive development and protecting shield of the symptoms of autism.
This observational study was funded by the Spanish government and published in the American Journal of Epidemiology. They studied more than 2,000 pregnant women in all of Spain. During pregnancy, the women reported fish intake through a questionnaire that categorizes food intake based on the type of fish.
Most women eat fish during pregnancy. The average amount eaten three servings a week. During birth, the umbilical cord blood of women measured the levels of mercury, contaminants that has to do with the effects of the poison to the nerves. It also measured DHA and omega three fatty acids.
After the birth, the woman's children were measured by scale development of the brain and the measurement scale indication symptoms of autistic spectrum disorders. Both trials were conducted when children aged 14 months and five years.
Eat more fish turned out to affect an increase in cognitive scores and a decrease in the symptoms of autistic spectrum children. Eating 600 grams of fish per week, about three to four servings was associated with an increase in IQ scores 2.8 points.
Surprisingly enough, it turned out the impact of protection and intelligence that comes from fish such as tuna are the most rich in DHA and mercury of all fish.
Umbilical cord blood tests revealed a high content of mercury and DHA for those who eat tuna. But the researchers did not look at the negative connection mercury and neurological development of children.
"It seems that we are more revealing indicator mercury fish consumption and its positive effects than the toxic effects of mercury," said Jordi Julves, researchers from the Center for Research in Environmental Epidemiology (Creal) Barcelona.
The benefits of eating fish was decreased when fish consumption of more than 600 grams.
