One year old infants with vitamin D deficiency are more likely to have a food allergy when compared to infants with higher vitamin D levels, according to research conducted at the Murdoch Childrens Research Institute (MCRI) in Melbourne, Australia.
Katrina Allen, PhD, and colleagues assessed vitamin D status and skin prick test results from 577 infants.
They found that infants of Australian-born parents, but not of parents overseas, with vitamin D insufficiency (<20 ng/ml) were more likely to have a peanut and/or egg allergy than were those with sufficient vitamin D levels. Furthermore, among infants with Australian-born parents, those with levels <20 ng/ml were more likely to have two or more food allergies rather than a single allergy.
The researchers conclude,
“These results provide the first direct evidence that vitamin D sufficiency may be an important protective factor for food allergy in the first year of life.”
