Eating oily fish during pregnancy may reduce asthma risk in children, study says

A new study has claimed that children born to mothers who eat salmon during pregnancy may be at lower risk of developing asthma in comparison to kids whose mothers do not eat it.

Researchers from University of Southampton in the UK led by Philip Calder conducted the Salmon in Pregnancy Study, a randomized controlled sample in which a group of women consumed salmon twice a week from week 19 of pregnancy. Allergy tests were then carried out on the children at six months and then at two to three years of age.

Results were matched with a control group whose mothers did not eat salmon during pregnancy. The findings revealed that at six months there was no difference in allergy rate between the two groups of children. However, at age two and half years, children whose mothers consumed salmon during pregnancy were less likely to have asthma.

Calder's previous research has shown that some fatty acids - or their absence is associated with broad spectrum of common diseases ranging from various allergies to atherosclerosis and inflammatory conditions such as Crohn's disease.

The study was presented at the yearly Experimental Biology Congress in San Diego, US.
