Taking fish oil while pregnant does not improve the brain development of babies, new research has found.

一项新研究发现，在怀孕期间服用鱼油并不能提升宝宝大脑的发育。

Fish oil has been marketed to women as a prenatal supplement.

鱼油一直被当作一种孕期补充剂而向女性推销。

But a 10-year study of more than 2,500 pregnant women found it did not improve babies' intelligence.

不过一项对超过2500名怀孕女性、持续十年的研究发现，鱼油并没有提升宝宝的智商。

The findings suggested that fish oil might lead to slightly longer pregnancies¹, but that would require further research.

该研究结果还表明，服用鱼油可能会导致孕期会稍微变长，但这需要进一步证实。

"If a pregnant woman has a healthy, balanced diet, then the baby's brain development is not going to benefit from having these fish oil supplements," study co-author Dr Jacqueline Gould told the BBC.

这项研究的合著者杰奎琳·古尔德教授在接受BBC采访时表示：“如果一位怀孕的妇女饮食搭配健康、均衡，那么宝宝大脑的发育就不会受益于这些鱼油补充剂。”

The research, by the South Australian Health and Medical Research Institute, followed women from their pregnancy² to when their children were seven years old.

由南澳大利亚州健康与医学研究所进行的这项研究，是从这些女性怀孕到孩子7岁一直进行跟踪。

Participants were given either a daily fish oil supplement or a placebo³.

这项研究的参与者被分成两组，一组每天服用鱼油，另一组则服用安慰剂。

The results found taking a 800mg dose of docosahexaenoic acid (DHA), an omega-3 acid, had no impact on babies' intelligence.

研究结果发现，每天服用800毫克的DHA（一种Omega-3脂肪酸），对于婴幼儿的智力发育并没有任何影响。
