This chapter discusses the background, prevention, diagnosis, treatment, and prognosis for food allergy. A food allergy is an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a given food. The food allergy is distinct from other adverse health consequences from food such as intolerance (non-immunologic, e.g. lactose intolerance) or other non-immune-mediated reactions (e.g. toxic, pharmacologic). Diagnosis relies upon a careful history and is confirmed by tests including skin prick tests, serum tests for food-specific IgE, elimination diets, and oral food challenges. Treatment relies upon allergen avoidance and preparation to treat severe reactions promptly with epinephrine. Prognosis is excellent for resolution of many childhood food allergies, although allergies to peanut, tree nuts, fish, and shellfish are likely to persist. Annual testing for children with allergies to milk, egg, wheat, and soy is generally undertaken.

Researchers have found a relationship between having food allergies and anxiety in children. Anxiety may relate to others' lack of food allergy knowledge. This study investigated the relationship between having a food allergy and self-reported anxiety among children. Furthermore, knowledge of food allergies among children without food allergies and teachers was explored.Children with food allergies and their parents each completed a perceived food allergy severity questionnaire. Children without food allergies completed a food allergy knowledge measure. All children completed a self-reported anxiety measure. Teachers completed a questionnaire investigating knowledge, attitudes, and beliefs about food allergies. Correlational analyses and analyses of variance were conducted.Overall anxiety was significantly higher in children with food allergies than in children without food allergies. When controlling for the effects of sex and age, children with food allergies had significantly higher social phobia and school phobia. Teachers correctly answered 69.7% of knowledge-based questions about food allergies; children without food allergies correctly answered 62.7%.Findings highlight the need for an integrated approach in which families, school personnel, psychologists and other mental health professionals, and medical professionals work together to increase awareness about the multifaceted needs of children with food allergies.

The prevalence of food allergies continues to increase. Literature shows child diagnosis of a food allergy has implications for parents (e.g., higher levels of anxiety), which can influence food parenting practices (FPP). As such, the primary aim of the current study was to investigate whether FPP differ between parents of children with and without a food allergy. The secondary aim was to investigate whether secondary factors, such as historical severity of allergic reaction, will also affect FPP. Participants were parents of children (N = 399) who completed online surveys about health history, including food allergy history, and FPP (Child Feeding Questionnaire, Structure and Control in Parent Feeding). About one-quarter (24.6%; n = 98) of children had at least one food allergy. A series of ANOVAs were conducted to assess differences in FPP between children with and without food allergies. Secondary analyses were conducted among parents of children with food allergies to examine how professional diagnosis, parental food allergy, reaction severity, hospitalization history, and presence of other chronic conditions affect FPP. Parents of children with food allergies were more likely to report limit setting FPP (p = .035); there were no other significant differences in FPP between children with and without food allergies (ps > .133). Among families with food allergies, parents whose children were not professionally diagnosed with a food allergy reported greater use of restrictive feeding practices (p = .019). Compared to parents without a food allergy, when both parent and child have a food allergy, parents reported higher pressure to eat (p = .006, p = .046), use of control (p = .039), and structured feeding routines (p = .039). Current findings illustrate that FPP are similar between parents of children with and without food allergies, with parents of children with food allergies engaging in more limit setting. However, in families with a food allergic child, other factors, such as parental food allergy history, were associated with increased use of controlling FPP. Given that food parenting practices have implications for child health, it is critical to work with parents of children with food allergies to help reduce use of controlling food parenting practices.

Patients with suspected food allergies are commonly seen in clinical practice. Although up to 15 percent of parents believe their children have food allergies, these allergies have been confirmed in only 1 to 3 percent of all Americans. Family physicians must be able to separate true food allergies from food intolerance, food dislikes, and other conditions that mimic food allergy. The most common foods that produce allergic symptoms are milk, eggs, seafood, peanuts, and tree nuts. Although skin testing and in vitro serum immunoglobulin E assays may help in the evaluation of suspected food allergies, they should not be performed unless the clinical history suggests a specific food allergen to which testing can be targeted. Furthermore, these tests do not confirm food allergy. Confirmation requires a positive food challenge or a clear history of an allergic reaction to a food and resolution of symptoms after eliminating that food from the diet. More than 70 percent of children will outgrow milk and egg allergies by early adolescence, whereas peanut allergies usually remain throughout life. The most serious allergic response to food allergy is anaphylaxis. It requires emergency care that should be initiated by the patient or family using an epinephrine autoinjector, which should be carried by anyone with a diagnosed food allergy. These and other recommendations presented in this article are derived from the Guidelines for the Diagnosis and Management of Food Allergy in the United States, published by the National Institute of Allergy and Infectious Diseases.

Food allergy is often the first manifestation of allergy in a child, and this problem is most relevant at an early age. With an allergic reaction to food, a seemingly not very significant pathology, a so-called «atopic march» may begin with the development of severe forms of allergic diseases in a child. At the same time, a favourable course of food allergy is possible with the disappearance of disorder signs with age. The disease prognosis depends on many factors, both genetic and environmental, but early diagnosis and adequate treatment of children with food allergies in most cases allow to improve the prognosis of tolerance formation or, at least, to achieve a mild course of food allergy manifestations. It is pediatricians who first deal with early manifestations of food allergies, and adherence to clinical guidelines for managing patients avoids the most common mistakes. This article is addressed to practicing doctors. It considers the most common mistakes of pediatricians in the management of children with food allergies and discusses the surviving «myths» about this pathology.

Food allergy is often thought to be a cause of rhinitis by patients, whose views are frequently influenced by information obtained from the Internet. The incidence of food allergy in children is 2–8 per cent, although a vast majority will grow out of it, and food allergy is actually very rare in adults. Food allergy usually presents with multi-system involvement, most commonly cutaneous and gastrointestinal symptoms. Food allergy induced rhinitis is less common, and isolated rhinitis due to food allergy is extremely rare. Treatment for rhinitis due to food allergy is therefore rarely indicated. This review summarises the literature related to the incidence, diagnosis and management of food allergy and food allergy induced rhinitis.
