Could Low Vitamin D Levels Cause Allergies?

A study of more than 3,000 children has found that low vitamin D levels are associated with increased likelihood that children will develop allergies.

Researchers examined serum vitamin D levels in the children’s blood.  Low vitamin D levels correlated with sensitivity to 11 of the 17 allergens tested, including both environmental allergens such as ragweed, oak trees, dogs and cockroaches, and food allergens such as peanuts.

Eurekalert reports:

“For example, children who had vitamin D deficiency (defined as less than 15 nanograms of vitamin D per milliliter of blood), were 2.4 times as likely to have a peanut allergy than were children with sufficient levels of vitamin D (more than 30 nanograms of vitamin D per milliliter of blood).”
