“…In the current study, adult-onset allergies were observed to every assessed food. After wheat, the most common adult-onset allergies in our sample were shellfish, soy, tree nut, and fin fish, which were the top 4 allergies identified by Kamdar et al 13 Furthermore, the observed rates of adult-onset shellfish and fin fish allergy in our sample are not dissimilar to the rates of 60% and 40%, respectively, observed by Sicherer et al 8 more than a decade ago. The most common childhood-onset allergy was peanut, which underlines the importance of early-life primary prevention efforts, such as the targeted early introduction practices advocated by the recent Addendum Guidelines for the Prevention of Peanut Allergy in the United States.…”
This survey study provides nationally representative estimates of the distribution, severity, and factors associated with adult food allergy in the United States.

“…Less is known about the prevalence of food allergy in older children or adults. Most studies of food allergy prevalence in adults have been surveys undertaken at a single point in time . No studies have used food challenge to examine prevalence in these age groups.…”
It is generally accepted that the prevalence of food allergy has been increasing in recent decades, particularly in westernised countries, yet high‐quality evidence that is based on challenge confirmed diagnosis of food allergy to support this assumption is lacking because of the high cost and potential risks associated with conducting food challenges in large populations. Accepting this caveat, the use of surrogate markers for diagnosis of food allergy (such as nationwide data on hospital admissions for food anaphylaxis or clinical history in combination with allergen‐specific IgE (sIgE) measurement in population‐based cohorts) has provided consistent evidence for increasing prevalence of food allergy at least in western countries, such as the UK, United States and Australia. Recent reports that children of East Asian or African ethnicity who are raised in a western environment (Australia and United States respectively) have an increased risk of developing food allergy compared with resident Caucasian children suggest that food allergy might also increase across Asian and African countries as their economies grow and populations adopt a more westernised lifestyle. Given that many cases of food allergy persist, mathematical principles would predict a continued increase in food allergy prevalence in the short to medium term until such time as an effective treatment is identified to allow the rate of disease resolution to be equal to or greater than the rate of new cases.
“…In a retrospective chart review, approximately
15% of patients with an initial food allergy diagnosis developed the problem as an
adult [21]. The same study found that
age at first reaction peaked during the early 30s, although there was a wide range.…”
Section: Natural History Of Adult Food Allergiesmentioning
Purpose of Review
The goal of this review is to present an updated summary of the natural history
of major childhood and adult food allergies and report recent advances in potential
treatments for food allergy.
Recent Findings
The most common childhood food allergies are typically outgrown by adolescence
or adulthood. However, peanut/tree nut allergies appear to more commonly persist into
adulthood. Adults can develop new IgE-mediated food allergies; the most common is oral
allergy syndrome. There are multiple different approaches being tried as possible
treatments for food allergy.
Summary
The prevalence of food allergy appears to be increasing but the varied
approaches to treatment are being actively pursued such that an approved modality may
not be too far in the future.
