Lean can not outweigh the benefits of eating fish during pregnancy mercury exposure
#Cosmoread: For pregnant women, to eat fish every week may benefit their future child’s brain, and even, for some of the early signs of autism can reduce his or her risk of a new study according.
In the study, “eating fish during pregnancy” researchers in Spain followed about 2,000 mothers and their children, pregnant mothers’ beginning in the first quarter, until the children turned 5. The results showed that children whose mothers fish three to four those whose mothers ate fewer servings of fish a week had IQ scores that were 2.8 percent higher.
The study also showed that children whose mothers during their pregnancy, 21 ounces of fish per week (about three to four servings) showed no signs of mercury in fish eaten average negative children whose mothers ate less fish compared with the health impact of their development.
Pregnant women, because of its high levels of mercury have been discouraged from eating – – What makes that particularly surprising findings, such as tuna or tile-fish some fish from some of the greatest developmental benefits was associated Jordi Julvez, said study lead author and center for research in epidemiology in Barcelona in environmental research.
The study was observational, higher IQ scores between fish and does not prove a cause-and-effect relationship. However, the findings suggest that a compound called docosahexaenoic acid (DHA) any negative impact of high levels of mercury can increase, the researchers said.
Even the tuna mercury DHA, an omega-3 fatty acid that plays an important role in brain growth and development of higher levels of fish that can be caught that way eating fish during pregnancy is good for health, Julvez said.
“Maybe this effect is masking the negative effects that mercury come from,” Julvez told Live Science. Or, “It could be more rewarding than the toxic effects of mercury.”
The current recommendations of the US Food and Drug Administration recommends that pregnant women eat three servings of fish per week to two, and they are low in mercury such as salmon-type fish, choose.
Researchers studied the babies’ umbilical cord blood taken after they were born, and both mercury and DHA levels in their blood measured. Later, when the children were 14 months old, and again when they were 5, the researchers assessed the cognitive development of their children, and autism spectrum disorders (ASD) symptoms to be tested.
“Autism spectrum steady decline in symptoms was also observed” growing children whose mothers ate fish levels, the researchers wrote in their study.
Concerns about eating fish during pregnancy arose when some previous findings suggest prenatal exposure to mercury found in fish may increase the risk of developing health problems. For example, Harvard TH A study by researchers at the Chan School of Public Health found that increased consumption of fish containing methyl mercury and heart damage in children with a risk of irreversible damage to brain function can be added.It is also a reason eating fish during pregnancy.
The study, published in 2004 in the Journal of Pediatrics, researchers in Denmark, Faroe Islands, where seafood is a big part of the diet of people in more than 800 children examined in 1986 and 1987. Cord blood sample and the birth of children to mercury exposure for children ages 7 and 14 hair samples were taken.
They found that at the age of 7, along with their level of development of children tracked mercury exposure. For example, double-Border Environmental Protection Agency (EPA) set by the US for exposure to mercury at 1.5 to 2 months were behind them. These development issues did not seem to improve with age.
Although the link between fish consumption and brain development of more studies are needed, many new results in earlier studies that children with better results from eating fish during pregnancy is associated with are in line, Edwin VanWijngaarden, chief of epidemiology at the University of Rochester Medical center, who was not involved in the new study.
Kids fish VanWijngaarden people who Seychelles (Indian Ocean Islands) lives consumptionthatlooked, at least eight fish per week to consume food containing a larger study. VanWijngaarden 2013 found that omega-3 fatty acids in fish is beneficial to the development of children’s language.
“This [study], because the FDA and EPA in their 2014 draft advice on the benefits of fish consumption among pregnant women and least stressed intake is advised, while taking care that much bigger fish mercury known for material not to consume, “VanWijngaardensaid.
Researchers in the new study until the age of 9 will continue to follow the children, Julvez said.
