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.

But a study by Danish scientists shows that treatable bacterial infections can also be a culprit.
