Pregnant Women Who Eats Fish Will Make Baby Intelligent

Based on the recent study, pregnant moms who eat fish (with less mercury) regularly have preschoolers who are more intelligent.

Researcher discovered that 341 3-year old kid whose moms eats more than 2 servings of fish each week when they were pregnant, in general shows higher results during verbal, visual and motor development test.

Meanwhile, preschoolers whose mother has higher level of mercury in their blood when they were pregnant showed low score in the test.

According to the  report of the researchers in American Journal of Epidemiology,  those who eat fish has bigger chances of having mercury levels in their blood compared to those who don’t eat fish.

Fish is considered as “brain food” but it is important to pick fish which has lower mercury.

“Recommendations for fish consumption during pregnancy should take into account the nutritional benefits of fish as well as the potential harms from mercury exposure,” says Dr. Emily Oken of Harvard Medical School in Boston.



Oily fish like salmon, tuna and sardines contains omega-3 fatty acids which is important in the development of the brain of a child. The only problem is that fatty fish may have the possibility of being contaminated by mercury, a toxic metal which can poison brain cells, particularly a fetus or a child.

However, Swordfish, king mackerel and  tilefish should be avoided by pregnant women. These fishes contain high levels of mercury because they eat other fish and have longer life which enables them to collect more mercury in their fat tissue.



U.S. health officials recommend pregnant women to eat not more than 12 ounces of fish or 2 servings each week.
