This systematic review and meta-analysis examined the prevalence of food allergies specifically in older adults, pooling data across available studies to estimate how common food allergy is in this age group.
The body of literature on food allergy in older adults is limited; studies likely vary widely in diagnostic criteria and methodology, which may affect pooled estimates.
Clinicians should be aware that food allergy is not exclusively a pediatric condition — screen older adult patients for food allergy when relevant symptoms arise.
