Omega-3s During Pregnancy Reduces Kids' Eczema and Egg Allergy Risk
In a new study, researchers determined that supplementation with omega-3 fatty acids during pregnancy reduces the risk of eczema in children by about 36%, and egg allergy by 50%. The findings are from the largest clinical to date studying the effects of omega-3 supplementation in pregnant women.
The DOMInO trial (DHA to Optimise Mother and Infant Outcome) required pregnant women in the omega-3 group to consume three 500 mg capsules of fish oil (equivalent to 900mg omega-3) per day starting from Week 21 of pregnancy. The multi-centered, randomized, double-blind, placebo-controlled clinical trial, then measured IgE-associated allergic disease (eczema or food allergy with sensitisation) at one year of age.
While the researchers reported no differences in the overall percentage of infants with IgE-associated allergic disease between the omega-3 and control groups, they did note that the incidence of eczema and egg sensitisation were lower.
They reported that children whose mothers had consumed omega-3 daily had 36% less risk of developing eczema, a 38% reduction in the chance of being sensitised to egg, and 50% less chance of having egg allergy.
