About three of every 100 people in the U.S. have at least one food allergy, and the presence of a food allergy may raise their risk of asthma, a study shows.
The study, which appears in the October issue of Journal of Allergy and Clinical Immunology, is the largest to offer a national snapshot of food allergy prevalence.
Children are at greater risk for food allergy than adults, and black male children are particularly at risk, the study shows.
“This gives us a good perspective, and the prevalence number is pretty solid,” says study researcher Andy Liu, MD, an allergist at National Jewish Health in Denver.
Food allergies are on most everyone’s radar screen these days with growing numbers of schools calling themselves “peanut-aware” or “peanut-free” and parents routinely asked to provide information on their child’s food allergies.
