Pregnant women do not have to "use mercury waste fish"!

Text ｜ Wang Fang

British scientists brought together the analysis of 4,131 pregnant women and children in the 1990s, and conducted similar studies in Seychelles, and then called for the guidance suggestions for changing pregnant women during pregnancy.

Related papers have recently published in "Neurotoxicology". It is important that researchers have also found that it does not seem to be important to eat, because the essential nutrients in fish can offset the mercury content in its body. The more important factor is whether women eat fish. This is in sharp contrast to the suggestions that pregnant women do not consume some fish with relatively high mercury content.

Although several studies have considered this issue before, this study focuses on two comparative studies. The interviewee is the people who measure mercury content during pregnancy, and their children are often followed in their childhood.

The first item is a research on the population of Seychelles, where almost all pregnant women eat fish. The second study considers the 1990s. The University of Bristol was based on ALSPAC data based on a industrialized area in southwestern England, where the fish consumption was much lower.

Although for a while, people have always believed that eating fish during pregnancy has many benefits for children's vision and intelligence, but official suggestions have warned not to eat fish with relatively high mercury content. As a result, some women may stop eating any fish for "safety reasons".

"We found that if the mother eats fish, the mercury content in the mother during pregnancy may not adversely affect the child's development during pregnancy. If the mother does not eat fish during pregnancy. The mercury content may have a harmful effect on children. "

Taylor explained that this may be because fish provides a variety of necessary nutrients, including long -chain fatty acids, iodine, vitamin D and selenium.

Jean Golding, a co -author of the study, a professor of peripheral epidemiology at the University of Bristol University, said: "Health professionals should modify their suggestions on not eating certain fish. There is no evidence to show that these fish will cause damage, but there are some, but there are some. Evidence from different countries shows that such suggestions will confuse pregnant women. "

"Pregnancy guide should emphasize‘ eating at least two fish a week, one of them is oily ’, and ignores all warnings that should not eat certain fish." Golding said.
