Many common foods including cow’s milk, hen’s egg, soya, peanut, tree nuts, fish, shellfish, and wheat may cause food allergies. The prevalence of these immune-mediated adverse reactions to foods ranges from 0.5% to 9% in different populations. In simple terms, the cornerstone of managing food allergy is to avoid consumption of foods causing symptoms and to replace them with nutritionally equivalent foods. If poorly managed, food allergy impairs quality of life more than necessary, affects normal growth in children, and causes an additional economic burden to society. Delay in diagnosis may be a further incremental factor. Thus, an increased awareness of the appropriate procedures for both diagnosis and management is of importance. This paper sets out to present principles for taking an allergy-focused diet history as part of the diagnostic work-up of food allergy. A short overview of guidelines and principles for dietary management of food allergy is discussed focusing on the nutritional management of food allergies and the particular role of the dietitian in this process.

Common Misconceptions

Background: Food allergies are common, affecting 1 in 13 school children in the United States and their prevalence is increasing. Many misconceptions exist with regards to food allergy prevention, diagnosis and management. Objective: The main objective of this review is to address misconceptions with regards to food allergies and discuss the optimal, evidence-based approach for patients who carry this diagnosis. Observations: Common misconceptions in terms of food allergy prevention include beliefs that breastfeeding and delayed introduction of allergenic foods prevent the development of food allergies. In terms of diagnosis, statements such as ‘larger skin prick tests or/and higher levels of food-specific IgE can predict the severity of food-induced allergic reactions’, or ‘Tryptase is always elevated in food-induced anaphylaxis’ are inaccurate. Additionally, egg allergy is not a contraindication for receiving the influenza vaccine, food-allergy related fatalities are rare and peanut oral immunotherapy, despite reported benefits, is not a cure for food allergies. Finally, not all infants with eczema will develop food allergies and epinephrine auto-injectors may unfortunately be both unavailable and underused in food-triggered anaphylaxis. Conclusions and relevance: Healthcare professionals must be familiar with recent evidence in the food allergy field and avoid common misunderstandings that may negatively affect prevention, diagnosis and management of this chronic disease.

Distinguishing Features

Food allergy is an emerging epidemic that affects all age groups, with the highest prevalence rates being reported amongst Western countries such as the United States (US), United Kingdom (UK), and Australia. The development of animal models to test various food allergies has been beneficial in allowing more rapid and extensive investigations into the mechanisms involved in the allergic pathway, such as predicting possible triggers as well as the testing of novel treatments for food allergy. Traditionally, small animal models have been used to characterise immunological pathways, providing the foundation for the development of numerous allergy models. Larger animals also merit consideration as models for food allergy as they are thought to more closely reflect the human allergic state due to their physiology and outbred nature. This paper will discuss the use of animal models for the investigation of the major food allergens; cow's milk, hen's egg, and peanut/other tree nuts, highlight the distinguishing features of each of these models, and provide an overview of how the results from these trials have improved our understanding of these specific allergens and food allergy in general.

State Of The Science

In the past several years, food allergies have taken center stage in the media and have become a topic of great concern for our patients and their families. Whether or not this is due to a rise in the prevalence of food allergies or just a heightened awareness, it is our responsibility as clinicians and scientists to critically analyze the current evidence available concerning the epidemiology, manifestations, diagnosis, and management of this disease. In 2010, the National Institute of Allergy and Infectious Diseases (NIAID) published guidelines concerning the diagnosis and management of food allergies. Since 2009, the Allergy, Asthma and Immunology Committee of the American Academy of Otolaryngology—Head and Neck Surgery has sponsored a miniseminar titled, “Food Allergy: State of the Science.” This commentary focuses on the highlights from the 2010 meeting and provides some thoughts on what this latest publication means to otolaryngologists.

The Relationship

Food allergies are potentially fatal immune-mediated disorders that are growing globally. The relationship between sex and food allergy remains incompletely understood. Here we tested the hypothesis that, should sex influence the clinical response to food allergens, this would be reflected by a sex disparity in published studies of food allergy. We performed a systematic search of the PubMed literature for IgE-mediated allergy to 11 allergenic foods of international regulatory importance. No date restriction was used and only articles in English were considered. Of the 4744 articles retrieved, 591 met the inclusion criteria representing 17528 subjects with food allergies. Whereas among children with food allergies, 64.35% were males and 35.65% were females (male/female ratio, 1.80), among adults 34.82% were males and 65.18% were females (male/female ratio, 0.53). Consequently, these data argue that there is need for further investigation to define the role of sex in the pathogenesis of food allergy.

Background: The diagnosis of non-IgE mediated food allergies may be a complex puzzle when there is no start point to establish an elimination diet to allow a clear clinical field to initiate diagnostic Oral Food Challenges tests. Objective: To evaluate the opportunity of the tube titration of precipitins to select food allergens to proceed with elimination diets to assist the diagnosis and management of adult patients with Food Allergy manifested as Intrinsic Atopic Dermatitis (IAD). Methods: The tube titration of specific precipitins against anamnesis-chosen food allergens were performed in 64 IAD patients and their titers were associated with an Improvement Verbal Scale Rate (IVSR) of the patient’s perception of the benefits of the Precipitins-based Elimination Diet (PED) performed with these specific food allergens, as well correlated with their positive or negative perception of the impairment of symptoms after the reintroduction of the Symptom-Related Food Allergen (SRFA). Results: In most cases, the PED contributed to a significant clinical improvement that allowed the patients to evaluate the individual effect of the reintroduction of each food allergen on their diets. There was a significant positive correlation coefficient between the titers of the food-specific titration of precipitins and the percentage of positive SRFA (Pearson r = 0.91; p-value = 0.0004). Conclusion: The semiquantitative titration of specific precipitins against food allergens is a promising triage test to select food allergens to proceed with elimination diets to support the diagnosis and management of non-IgE mediated Food Allergy in patients with Intrinsic Atopic Dermatitis.

Background: Adverse reactions to foods are divided in two main groups: food intolerance (non-immune process) and food allergies (immune-mediated process). The food allergy (FA) is a common and on rise condition in population. Although there is possibility of preventive or symptomatic relief through use of antihistamines and corticosteroids, it lacks full cure. Heretofore, it was believed that the only really effective treatment against this condition would be complete allergen restriction. Aim: To review the immune mechanisms related with food allergy and propose a new therapeutic technic called desensitization. Methods: Non‑systematic review. Findings: FA is more common in children and in patients with other allergic conditions. Allergies related to peanut/milk/egg/fish/crustacean shellfish are more common and permanent. FA is a complex and multifactorial process, which mixes genetic and environmental factors. Conclusion: Food allergy is a health problem worldwide. Scientists still need a better understand of the immune mechanisms involved in the food allergy pathogenesis & in the human susceptibility to allergens. Therefore, scientists will need to improve definitive therapeutic modalities to avoid dramatic outcomes.
