February 27/Halle-Wittenberg, Germany/RedOrbit -- Adding a little vitamin D supplement to the diet while pregnant may put the child at risk of developing a food allergy after birth, according to a new study published in the journal Allergy.

The Helmholtz Centre for Environmental Research and the Martin Luther University in Halle-Wittenberg in Germany sought out to prove that there is a correlation between the concentration of vitamin D in the blood of expectant mothers and in the cord blood of babies. Cord blood is the blood that remains in the placenta and in the attached umbilical cord after childbirth.
