A recent study to be published in Pediatrics done at Emory University found that women taking 400 mg / day of DHA had children with fewer cold symptoms than the placebo group.
Women who took DHA had infants that had nearly a 25% lower occurrence of colds during infancy. If the baby did develop a cold their symptoms improved faster than the placebo group.
Children get their DHA during pregnancy and by breastfeeding. The mothers who took the DHA had higher levels of DHA in both their breast milk and their blood plasma. This suggests that DHA is essential to both the fetus and infant in developing a normal and healthy immune system.
The graphs below show the difference in symptoms between the DHA group and the placebo group. (Note not on graph but at 6 months the DHA group did show increase in vomiting.)
DHA is also very important also for neurological function and it would be interesting to look at intelligence and neurological development further down the road with this same group. However the study does make clear that DHA does help the developing infant’s immune system. DHA should be a part of every mother’s prenatal routine.
