The findings found that women who were prescribed 2.4 grams of long-chain Omega-3 supplements during the third trimester of pregnancy reduced their children's risk of asthma by 31 per cent.


Long-chain Omega-3 fatty acids, which include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found in cold water fish, and key to regulating human immune response.


One of the researchers Hans Bisgaard from Copenhagen University Hospital, Denmark said, "We've long suspected there was a link between the anti-inflammatory properties of long-chain omega-3 fats, the low intakes of Omega-3 in Western diets and the rising rates of childhood asthma".


"This study proves that they are definitively and significantly related," Bisgaard added.


Researchers analysed blood samples of 695 Danish women at 24 weeks' gestation and one week after delivery for the study.


They then monitored the health status of each participating child for five years, which is the age asthma symptoms can be clinically established.


The study used rapid analytical techniques developed and performed at the University of Waterloo in Canada to measure levels of EPA and DHA in pregnant women's blood.


The testing also revealed that women with low blood levels of EPA and DHA at the beginning of the study benefited the most from the supplements.


For these women, it reduced their children's relative risk of developing asthma by 54 per cent, showed the findings published in the New England Journal of Medicine.
