研究人員選取了695名孕婦作為受試者。研究發(fā)現(xiàn)，每天攝取2.4克魚(yú)油補(bǔ)充劑的孕婦，嬰兒患哮喘等呼吸道疾病的幾率降低了30.7%。
根據(jù)美國(guó)國(guó)家老化研究所（National Institute on Aging），2.4克魚(yú)油約是美國(guó)人通過(guò)食物攝取平均量的15到20倍。世界衛(wèi)生組織（WHO）建議每天劑量不應(yīng)超過(guò)3克，因?yàn)閿z入過(guò)多可導(dǎo)致出血和低血壓，甚至?xí)c藥物或維他命A、D和E起反應(yīng)。
部分原文報(bào)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.
The 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 response that is a factor in asthma and related conditions.
