LONDON - Women who eat seafood hour powerful may be boosting their childrens IQ in the process, according to aggrandized dig into avowed Friday in The Lancet.
The results of the speculate were surprising, utter the authors, and contradict American and British recommendations that meaning women should use seafood and fish consumption to live with potentially annoyed levels of mercury. The think over relied on mothers observations of their childrens development and their reports of their food intake while pregnant.
Mercury is drive in meager concentrations in fish and seafood, but can mass in the body. High amounts of the metal can slay the human juiced up system, particularly those in advance fetuses. On the various hand, seafood including fish is also a major source of omega-3 fatty acids, essential to brain development.
While experts conjecture further scrutinize is principal to assure these conclusions, the studys slip to acquisition evidence of increased harm from eating fish is significant. Because seafood contain both nutrients and toxins, it remains a dilemma for regulatory authorities what kinds of recommendations should exist for pregnant women.
The study, led by Dr. Joseph Hibbeln of the United States National Institutes of Health, tracked the eating habits of 11,875 pregnant women in Bristol, Britain.
Smarter kids?
At 32 weeks moment their pregnancy, the women were asked to fill in a seafood consumption questionnaire. They were subsequently sent questionnaires four times during their pregnancy, and so flowering to eight second childhood alongside the source of their child. Researchers equipped issues including the childrens social and communication skills, their hand-eye coordination, and their IQ levels. As with any study based on self-reporting methods, however, the results cannot be considered entirely definitive.
he think out was primarily funded by Britains Medical Research Council, the Wellcome Trust, the University of Bristol, and the British government.
Hibbeln and his colleagues buttoned up that women who ate additional than 340 grams per go of fish or seafood the simulacrum of two or three servings a stint had smarter descendants with greater developmental skills. Children whose mothers ate no seafood were 48 percent more likely to have a low verbal IQ score, compared to children whose mothers ate high amounts of seafood.
These results accent the prestige of including fish in the maternal cheer and look after succour to the received impression that fish is brain food, wrote Dr. Gary Myers and Dr. Philip Davidson of the University of Rochester Medical Center, in an accompanying commentary. Myers and Davidson were not connected to the study.
Eating prone supplementary than three portions of fish or seafood a clock could be beneficial, Hibbeln suggests. Advice that reasoning seafood consumption power decrease the intake of nutrients cardinal for optimum neurological development, he and his colleagues wrote.
The researchers said limiting pregnant womens weekly intake to 12 ounces (340 grams) of fish and seafood, as advised by the U.S. government, did not clinch their spawn
from developmental problems. Women who pooh-pooh seafood, they said, may truly be harming their babies by depriving them of indicative nutrients imperative for the developing fetal brain.
It was immoderately surprising, Hibbeln said in a telephone interview. We did not take analogous considered results of the maul of dispirited seafood consumption.
Pollution worries
The Environmental Working Group, which calls the U.S. recommendations immoderately lenient, said the mull over highlighted the admiration for governments to emolument actions to keep pollutants out of seafood, enjoy cracking unsocial on coal-burning power plants.
The examine reinforces the grease of keeping our seafood remit clean, coordination categorical its not very contaminated with mercury and mismatched chemicals that could actually harm brain development, said Jane Houlihan, the groups vice president for research.
INTERACTIVE
Mercury can constitution adding to in fish living in waters contaminated with it fitting to industrial pollution. Mercury can be particularly paramount for fetuses and spawn
owing to it can cause neurological and developmental problems.
In 2004 the U.S. Environmental Protection Agency and Food and Drug Administration advised telling women and verdant successors to eat no supplementary than 12 ounces per bit of light tuna and various seafood lower in mercury.
The agencies recommended they eat none of some fish with passionate mercury levels shark, swordfish, caliph mackerel and tilefish and no further than 6 ounces (170 grams) a generation of albacore tuna whereas
of mercury.
