Food allergy can be a confusing topic and not all bad reactions to food are actually due to an allergy. If you think you may have a food allergy, discuss it with your doctor.
Food allergy is a common problem affecting as many as 1 in 25 young children but is much less common in adults. Food allergy is more common in people with eczema. Among children under 5 who have eczema, as many as 30% may also have food allergy.
