Update on food allergy in adults.

Though much has been studied and written about food allergy, the majority of the available literature focuses on food allergies in the pediatric population. Unfortunately, it is likely that in regard to food allergies, adults are not just big children, and extrapolating findings from pediatric to adult patient populations might lead to erroneous assumptions. Thus, it is important to validate the correlation between pediatric and adult data, gather data regarding adult food allergy and understand the specific nuances of subsets of adults to better treat their food allergy. This review was conducted by identifying potentially relevant studies regarding food allergies in adults through electronic databases, including PubMed, Medline, and Google Scholar. The search terms included "allergy", "food" and "adults". Parameters of 19+ years of age were added to search terms and all journals were written in or translated to English. From these search results, focus was placed on studies from 2010 to 2012. This systematic update on food allergy in adults found that the evidence regarding prevalence, diagnosis and management of food allergies is very limited, with the majority of data derived from children and young adults.
