研究发现孕期补充鱼油降低婴儿哮喘几率

讯据外媒报道，《新英格兰医学杂志》刊登一项丹麦研究发现，孕期最后3个月摄取足量的鱼油，可降低孩子3岁前哮喘的机率。

研究人员选取了695名孕妇作为受试者。研究发现，每天摄取2.4克鱼油补充剂的孕妇，婴儿患哮喘等呼吸道疾病的几率降低了30.7%。

根据美国国家老化研究所（National Institute on Aging），2.4克鱼油约是美国人通过食物摄取平均量的15到大花洽草20倍。世界卫生组织（WHO）建议每天剂量不应超过3克，因为摄入过多可导致出血和低血压，甚至会与药物或维他命A、D和E起反应。

部分原文报道如下：

A Danish study of 695 pregnant women is raising the possibility that fish oil supplements begun in the final three months of pregnancy may reduce the risk of asthma or persistent wheezing in offspring.

T蒙古堇菜he supplements brought the risk from 23.7 percent among mothers in the placebo group who took 2.4 grams of olive oil daily down to 16.9 percent in the women who got the fish oil capsules. That's a 30.7 percent reduction during the first three years of life.

The real benefit seemed to be exclusively among the children whose mothers started out with low levels of the two key ingredients in fish oil - eicosapentaenoic acid （EPA） and docosahexaenoic acid （DHA）。 That may make them more vulnerable to the inflammation and heightened immune system微毛樱桃 response that is a factor in asthma and related conditions.
