Research suggests link between lipid levels, risk of allergies

For children and teens who suffer from respiratory allergies, an IQAir HealthPro Plus medical-grade air filtration system can help reduce the likelihood of airborne irritants causing an allergic reaction. While this may be welcome news for parents of children with these conditions, the underlying causes of respiratory allergies have remained unclear - until now. New research has linked levels of omega-3 and omega-6 lipids in children's cord blood at birth with their likelihood of developing allergies in later life.

Researchers at the Chalmers University of Technology in Sweden identified a correlation between the presence of poly-unsaturated fatty acids in cord blood with the possibility that children will develop respiratory and skin allergies in adolescence. In addition, children who suffered from these allergies in their teens also had significantly lower levels of mono-unsaturated fats in their cord blood at birth than those who did not show signs of respiratory and dermatological allergies.

"The mechanism by which these lipids affect allergy development is unknown, but may involve dampening of the immune activation in infancy needed for proper maturation of the infant's immune system," read a statement in the study, which was published in the open-access "PLoS One" scientific journal.
