Pregnant? Avoid fish...
13 Oct, 2006 1253hrs ISTIANS

NEW YORK: Researchers in the US have warned pregnant women to limit their fish intake citing high mercury levels in oily fish.

The high mercury levels in fish such as mackerel, salmon and sardines could cause them harm, reported the online edition of *** News quoting a report published in the New Scientist magazine.

Dr. Fei Xue and colleagues looked at 1,024 pregnant women living in Michigan and measured the amount of mercury they had in their hair and compared this with the date that the women delivered their babies.

The women who gave birth more than two weeks early were three times as likely to have double the average mercury level in their hair samples, the researchers said. On the whole, these women also tended to eat more oily fish, particularly canned fish.

Only 44 of the women, however, gave birth prematurely, and the researchers said more work was needed to corroborate their findings.

They also pointed out that the women were asked to recall how much fish they had eaten, which might be inaccurate. It was also possible that the women could have been exposed to mercury from other sources too, they said.

Xue said until the risks become clearer, women could take fish oil supplements instead.

But experts warn it is important for pregnant women, and indeed everyone, to eat enough fish to keep healthy. Pregnant women should eat fish twice a week, says the Food Standards Agency.

But they should avoid shark, marlin and swordfish because these fish are particularly high in mercury and other pollutants.

Women who are breastfeeding and those trying for a baby should also eat two portions of oily fish per week. Other women, and men and boys, can eat up to four portions per week. One portion is about 140g of fish - one tuna steak, for example.

Pregnant? Avoid fish...
孕妇需要禁食鱼类吗？

NEW YORK: Researchers in the US have warned pregnant women to limit their fish intake citing high mercury levels in oily fish.
纽约路透社电美国科学家提醒孕妇要限制鱼类的进食，因为富含油的鱼类汞含量高。

The high mercury levels in fish such as mackerel, salmon and sardines could cause them harm, reported the online edition of *** News quoting a report published in the New Scientist magazine.
英国广播公司（***）网络版转载《新科学家》杂志上的研究报告：汞含量高的鱼类如鲭鱼、鲑鱼和沙丁鱼会对她们造成伤害。

Dr. Fei Xue and colleagues looked at 1,024 pregnant women living in Michigan and measured the amount of mercury they had in their hair and compared this with the date that the women delivered their babies.
Fei Xue博士及其同事检测了居住在密西根州的1024名孕妇头发中汞的含量，并比较了她们分娩的时间。

The women who gave birth more than two weeks early were three times as likely to have double the average mercury level in their hair samples, the researchers said. On the whole, these women also tended to eat more oily fish, particularly canned fish.
研究人员称，早产时间大于两周的孕妇，头发中平均汞含量是其他妇女的两倍。大体上来说，这些孕妇也进食了更多的富含油的鱼类，尤其是罐装鱼。

Only 44 of the women, however, gave birth prematurely, and the researchers said more work was needed to corroborate their findings.
同时，研究人员也指出，调查中仅有44名孕妇出现早产，因此需要更多的研究来证实这个发现。

They also pointed out that the women were asked to recall how much fish they had eaten, which might be inaccurate. It was also possible that the women could have been exposed to mercury from other sources too, they said.
他们还指出，这些孕妇回想的她们所进食的鱼类的量可能不准确。也有可能这些孕妇同时还暴露于其他汞源中。

Xue said until the risks become clearer, women could take fish oil supplements instead.
Xue说，在这种风险被确定之前，孕妇可以进食鱼油补充剂来代替鱼类食物。

But experts warn it is important for pregnant women, and indeed everyone, to eat enough fish to keep healthy. Pregnant women should eat fish twice a week, says the Food Standards Agency.
但是专家提醒，孕妇，甚至每个人，进食足够的鱼类来保持健康都是很重要的。英国食品标准局称，孕妇每周需要进食两次鱼类食物。

But they should avoid shark, marlin and swordfish because these fish are particularly high in mercury and other pollutants.
但是她们要避免进食鲨鱼、马林鱼和旗鱼，因为这些鱼中汞的含量及其他污染物的含量特别高。

Women who are breastfeeding and those trying for a baby should also eat two portions of oily fish per week. Other women, and men and boys, can eat up to four portions per week. One portion is about 140g of fish –
one tuna steak, for example.
进行人乳喂养的女性每周也需要进食两份富含油的鱼。其他女性、男性和孩子每周可以进食4份，每份大约为140克，例如一份鲔鱼鱼排。

整理了一下：
美国科学家提醒孕妇要限制鱼类的进食

纽约路透社电据《新科学家》杂志上的研究报告：孕妇要限制鱼类的进食，因为富含油的鱼类，尤其是鲭鱼、鲑鱼和沙丁鱼等的汞含量很高，这将对孕妇造成伤害。

美国学者Fei Xue博士及其同事检测了居住在密西根州的1024名孕妇头发中汞的含量，并比较了她们分娩的时间。他们发现早产时间大于两周的孕妇，头发中平均汞含量是其他妇女的两倍。而且总体上来说，这些孕妇进食富含油的鱼类也更多，尤其是罐装鱼。同时，他们也指出该研究存在一些不足，例如，这些孕妇所回想的进食的鱼类食物的量可能不够准确，也有可能这些孕妇同时还暴露于其他汞源中。Fei Xue博士称，在这种危险被确定之前，孕妇可以进食鱼油补充剂来代替鱼类食物。

但是，专家又提醒，孕妇乃至每个人都必须进食足够的鱼类来保持身体的健康。英国食品标准局称，孕妇每周需要进食两次鱼类食物，而进行人乳喂养的女性每周也需要进食两份（每份大约为140克）富含油的鱼。但是她们要避免进食鲨鱼、马林鱼和旗鱼等汞及其他污染物含量均特别高的鱼类。
