Kids’ Allergies May Correlate With Omega-3, Omega-6 Lipid Levels In Cord Blood
High polyunsaturated fat levels in cord blood raise risk of respiratory, skin allergies
Children with high proportions of poly-unsaturated fatty acids (PUFA) in cord blood at birth are more likely to develop respiratory and skin allergies in their early teens, according to research published July 10 in the open access journal PLOS ONE by Malin Barman and colleagues from the Chalmers University of Technology, Sweden.
Children with allergies at age 13 had higher proportions of omega-3 and omega-6 PUFAs in cord blood samples taken at birth. Compared to healthy children, allergy sufferers also had lower levels of mono-unsaturated fats in their cord blood. The risk of respiratory allergies in children with higher PUFA levels was equally significant in children with allergic and non-allergic mothers. The study says, "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."
