Researchers National Center for Health Statistics at the CDC report that food allergies have risen by almost 20% in kids over the last decade.
In the period from 1997-2007, food allergies in kids increased by 18%. Furthermore visits to doctors to treat these allergies including peanut butter allergy have increased by three times during the same period.
"Reported food allergy is increasing among children of all ages, among boys and girls, and among children of different races/ethnicities," researcher Amy M. Branum, MSPH and colleagues wrote. "However, it cannot be determined how much of the increases in estimates are truly attributable to increases in clinical disease and how much are attributable to increased awareness by physicians, other health care providers, and parents."
The details of the study are published in Pediatrics.
