Vitamin D, Breastfeeding and Food Allergy

Inasmuch as many infants develop allergic symptoms early in infancy, and exposure to allergens may be important in the development of food allergies, there is great interest in maternal dietary strategies during pregnancy and lactation that may prevent food allergies, and thus reduce the burden of disease. Vitamin D levels are known to be associated with atopic disease development in early infancy; however, existing data are controversial. The aim of this review was to investigate any possible effect of vitamin D on the onset of neonatal allergy via breast feeding.
