NEW YORK, Feb. 24 (UPI) -- Children with low levels of vitamin D have increased risk of developing allergies, New York researchers say.
Senior author Dr. Michal Melamed of the Albert Einstein College of Medicine at Yeshiva University looked at the serum vitamin D levels in blood collected in 2005-2006 from a nationally representative sample of more than 3,100 children and adolescents as well as 3,400 adults.
