Expert consensus on the diagnosis and management of IgE mediated food allergy in children

The prevalence of food allergy in children is increasing, which seriously affects the quality of life of children and their families. Among children and adolescents, IgE-mediated food allergy is the most common type. In recent years, allergen specific IgE (sIgE) and skin prick testing (SPT) have been widely used in clinical practice, with component resolved diagnosis (CRD) also gaining traction for precise diagnosis of IgE-mediated food allergy. However, a challenge persists in clinical practice due to the tendency to over-interpret food allergen test results without considering the patient's clinical history. While food avoidance remains the most effective treatment for IgE-mediated food allergy, there are varying approaches to clinical management. Strict food avoidance for non-severe food allergies may increase the patient's burden and impact their quality of life. To address these challenges, a consensus on the diagnosis and management of IgE-mediated food allergy in children has been developed based on the latest guidelines and research evidence. This consensus aims to guide physicians in standardizing the management of IgE-mediated food allergy in children.

A Multi-centre Analysis of Serum IgE Levels in Atopic Dermatitis

Abstract Objective: To assess the characteristics of total immunoglobulin E (IgE) and allergen-specific IgE (sIgE) to 20 common allergens in 154 patients with atopic dermatitis (AD). To assess the correlation of clinical food allergy with positive food allergens’ sIgE results. We further discuss the significance of IgE as a potential biomarker for AD disease severity. Methods: A total of 154 AD patients were collected from 15 hospitals nationwide in China from 2019 to 2021. Serum IgE was measured using reverse-enzyme immuno capture test (REAST). Patients were required to have at least one positive sIgE (N ≥ 0.35 IU/mL). Patients were divided into groups according to gender, age, disease severity, and region. SPSS 26.0 software was used for statistical analysis. Results: Compared with adolescent and adult, AD in infancy and childhood showed significantly higher frequencies of positive sIgE to food allergens, including egg, cow milk, and wheat (P < 0.01). However, adolescent and adult AD showed significantly higher frequencies of positive sIgE to inhaled allergens, dermatophagoides farinae, and house dust mite. In addition, sIgE in different sexes were different. Compared with women, men showed higher frequencies of positive allergen-specific IgE level to wheat, dermatophagoides farinae, and house dust mite. The most common food allergens with elevated sIgE levels were egg (71%), cow milk (39%) and wheat (32%). However, AD patients reported seafood, including crab, shrimp, and fish, as the most frequent food allergens which aggravate their disease in their daily life. Only 18 (12%) patients reported definite correlation of clinical practice with positive food allergens’ IgE results. Among 154 sIgE-positive patients, 99 patients had an increase of total IgE (≥60 IU/ml). TotalIgE (tIgE) levels were significantly different between mild (193 ± 239 IU/mL), moderate (170 ± 202 IU/mL), and severe (375 ± 343 IU/mL) forms of AD patients (P < 0.01). AD patients with accompanied allergic diseases showed significantly higher tIgE levels than those without accompanied allergic symptoms (280 ± 286 IU/mL vs 194 ± 248 IU/mL). Conclusion: Neither sIgE nor tIgE levels can be used to evaluate the condition or severity of AD. AD patients with accompanied allergic diseases showed significantly higher tIgE levels than those without accompanied allergic symptoms. Infantile AD patients are more allergic to food, while adolescents and adults are more allergic to environmental antigens. IgE tests must be interpreted by combining with clinical history to avoid unnecessary food avoidance. Early food allergen introduction for infants may be promising for the prevention of food allergies.

Prevalence of potential risk of eating disorders among young, unprofessional European athletes: results of the ERASMUS+ project SCAED.

Adolescent athletes are at higher risk of developing eating disorders (ED) due to sports environment pressures and developmental characteristics. The ERASMUS+ project Sports Community against Eating Disorders (SCAED) aims to assess the prevalence of the potential risk of eating disorders among young, unprofessional European athletes and to provide them with easier access to professional support and knowledge. The online survey included 462 unprofessional athletes from six European countries aged 12-25 (average age 18.49 ± 5.50) on their socio-demographics, sports and lifestyle habits, behaviors, concerns, and perceived pressure from coaches and teammates regarding body weight and shape. The eating disorder potential risk was assessed using the Eating Disorder Examination for Adolescents (EDE-A) and Eating Disorders Screen for Athletes (EDSA). Every seventh (14.9%, EDE-A) and fifth (19.9%, EDSA) of young, unprofessional European athletes were at possible risk for developing eating disorders. Overall potential risk (18.7% EDE-A, 26.6% EDSA), dietary restraint (12.9%), and concerns about eating (9.5%), shape (23.7%), and weight (19.6%) were significantly more prevalent among female athletes. Younger athletes showed a slightly higher prevalence and avoidance of food. Athletes training in weight-sensitive sports exhibited more behaviors related to eating disorders. Females (p = 0.003), younger, and those athletes training in less weight-sensitive sports noted higher weight- and shape-related pressure from coaches. Dissatisfaction with their current weight was expressed by 44.6% of athletes, while 46.1% thought that they needed to lose weight to improve performance. The observed prevalence of the potential risk of ED among young, unprofessional European athletes is concerning, particularly due to limited access to support. Efforts to reduce the prevalence should target female and younger athletes in weight-sensitive sports. The SCAED Erasmus+ project aims to decrease ED prevalence among young, unprofessional European athletes, their families, and coaches by supporting them through education and professional consultation.

Perceived healthiness of foods, food avoidance and diet-related anxiety in individuals with self-reported irritable bowel syndrome: a cross-sectional study

BackgroundIrritable bowel syndrome (IBS) is a common gastrointestinal disorder in which the intake of food is known to exacerbate symptoms. Experiencing food related symptoms can lead to avoidance of food, and cause anxiety related to food intake. We aimed to explore perceptions of the healthiness of food, food avoidance, and food-related worry and anxiety among individuals with and without IBS.MethodsThis study was based on a survey conducted in January-February 2017. In total, 2000 participants aged 20–65 were invited by postal letter randomly obtained through the Swedish state personal address register. The questionnaire included aspects of socioeconomic position, different disorders including IBS and food intolerances, food avoidance, and food-related worry or anxiety.ResultsIn total, 538 participants were included in this study, of whom 8.4% (n = 45) reported having IBS. There were few differences regarding the perceived healthiness of foods between individuals with and without IBS. Participants with IBS avoided gluten (OR 3.45, p = 0.002), lactose (OR 5.0, p < 0.001) and alcohol (OR 2.0, p = 0.042) more frequently than individuals without IBS, and avoidance was driven by abdominal pain. Participants with IBS also reported feeling more worried and having anxiety about diet than those without IBS (p = 0.032 and p = 0.002, respectively).ConclusionThis study indicates that individuals with IBS perceive most foods as equally healthy as individuals without IBS. Having IBS increases the odds of avoiding gluten, lactose, and alcohol. Worry and anxiety related to diet were more common among individuals with IBS, and these aspects need to be considered both in clinical practice and in future research.

Food Avoidance beyond the Gluten-Free Diet and the Association with Quality of Life and Eating Attitudes and Behaviors in Adults with Celiac Disease

Background: The only treatment for Celiac Disease (CeD), which affects about 1% of the population, is a gluten-free diet (GFD). Studies have indicated an association between the GFD, a diminished quality of life (QOL), and maladaptive eating patterns. This study aims to explore food avoidance behaviors in adults with CeD. Methods: This cross-sectional study assessed 50 adults with biopsy-confirmed CeD who completed validated surveys evaluating demographics, psychological factors, QOL, eating pathology, and food avoidance. Results: Overall CDQOL scores were good (mean: 62.7 out of 100). However, 58.0% of the participants self-elected to avoid one or more additional foods without diagnosed allergies or intolerances. Those avoiding one or more other foods had lower QOL scores (57.4 (23.2) vs. 70.2 (15.9)) compared to those only avoiding gluten (p = 0.034). The mean depression score (CESD) for the group avoiding foods beyond gluten was in the depressive range, unlike those avoiding only gluten (16.0 (4.9) vs. 13.6 (4.0), p = 0.078), with 77% of those avoiding more than gluten scoring above the CESD cut-off point of 15, indicating clinical depression. Conclusions: Over half of participants (58%) reported avoiding additional foods beyond the GFD, a behavior associated with decreased QOL and increased depression.

Component-resolved diagnostics of fruit and vegetable allergy: precise identification and individualized treatment strategies

Vegetable and fruit allergies are common types of food allergies worldwide, most of them are triggered by primary sensitization to pollen. Most allergens in vegetables and fruits belong to a few cross-reactive proteins such as PR-10 proteins, profilins, and nsLTPs. The presence of these allergens in various plants can lead to widespread cross-reactive allergic responses. Component-resolved diagnostics (CRD) can improve diagnostic accuracy by precisely identifying specific allergenic proteins, aiding physicians in making more accurate treatment and management decisions, and reducing unnecessary food avoidance. This article, based on the "Molecular Allergology User's Guide 2.0 (MAUG 2.0)" issued by the European Academy of Allergy and Clinical Immunology (EAACI), analyzes the primary mechanisms, relevant allergens, and diagnostic and clinical management strategies for vegetable and fruit allergies. By detailing and analyzing these allergenic components, this article may help the healthcare professionals to deep the understandings of vegetable and fruit allergies, offer new perspectives and practical guideline for the research and treatment of these allergies, and promot the development of precise diagnostics and personalized treatment strategies.

Single mandibular implant study - impact on dietary habits after 5 years of observation in patients with immediate and delayed loading protocols

ObjectivesSingle midline implants in the edentulous mandible can be used to support existing complete dentures to improve patients’ satisfaction and masticatory efficiency. The impact on patients’ dietary habits and the influence of the loading protocol of the implants was the subject of this study.Materials and methodsIn this prospective randomized clinical trial, edentulous patients with existing complete dentures in both jaws were treated with a single midline implant in the mandible. In group A, the implants were loaded immediately, in group B the loading was delayed after three months. Patients were asked to report on their nutritional intake before implant placement and 12, 24 and 60 months after loading using a standardized two-part questionnaire.ResultsNutritional intake regarding the frequency of consumption of the requested food items did not change significantly during the 60-months study period, regardless of the loading protocol. In contrast, the second part of the questionnaire revealed that after 60 months, there was a significant decrease in avoidance of food, that had a coarse and hard texture in both groups. This significant decrease was observable in the group A in the first 12 and 24 months and in the group B after 60 months.ConclusionA change in the patients’ dietary habits due to the insertion of a single midline implant in the mandible to support the existing complete denture cannot be observed, independently to the loading protocol.Clinical relevanceImproving the chewing efficiency by single midline implants in the edentulous mandible does not lead to a change in dietary habits.

Mixed-method Irish study exploring the role of diet in IBD based on an online questionnaire and a patient panel opinion.

Diet is a risk factor in inflammatory bowel diseases (IBD) pathogenesis. This study aims to examine the dietary patterns and beliefs of Irish patients living with IBD through an online questionnaire and subsequent open discussions with an IBD patient collaborator panel (PCP). All data presented here are selected and presented following the PCP's suggestions and views. This mixed-method study included an online questionnaire using a short food frequency questionnaire examining dietary patterns, dietary opinions, beliefs and behaviours (phase I). Six in-person PCP sessions were conducted, where findings from the online questionnaire, diet and lifestyle in the context of IBD were discussed in depth (phase II). The questionnaire revealed that respondents with active IBD are associated with the consumption of high-sugar, processed and meat-based foods while reducing their consumption of high-fibre foods. Individuals with active Crohn's disease have a decrease in overall daily energy consumption and a significant reduction in intake of fibre, non-starch polysaccharides, micronutrients [B vitamins (B1, B2, and B9), vitamin C, calcium] and trace elements (iron, zinc, copper and manganese). The PCP reported that food tolerability is limited during relapse, leading patients to prefer simple carbohydrates for energy, consistent with the dietary intake data. The PCP reported that most dietary advice was received during hospitalisation (relapse), focused on food avoidance, with little follow-up during remission. The consensus among the PCP was that factors, such as disease type, psychological aspects, dietary understanding and support, can influence peoples' dietary choices. In summary, we show that dietary intake in people with IBD varies and may depend on several factors, not just the disease itself. This PCP desires more dietary information and professional support outside of hospitalisation to assist with disease management.

Personalized Food Avoidance Dietary Approach for Psoriasis and Hypertension: A Case Study and Pilot Trial

Background: The comorbidity, coheritability and common immune pathways of the inflammatory ‘chronic’ (non-communicable) diseases, suggest a shared aetiopathogenic mechanism, with phenotypic localization dependent on genetic predisposition, for example, the arteries in hypertension and the skin in psoriasis. Lifelong observation of psoriasis suggests genetically predisposed toxicity of amphiphilic fats, flavor enhancers, and nonsugar sweeteners. Aim: To conduct trials of personalized dietary intervention to abate the phenotypic expression of psoriasis and hypertension. Materials and Methods: The interventional case study of psoriasis was conducted by means of repetitive dietary challenge and avoidance testing. We then conducted an open trial of personalized nutrition on nine consenting recruits with uncomplicated essential hypertension. They were counseled on which foods to avoid or to take based on the experience gained in psoriasis. Study participants with ‘GOOD’ or ‘FAIR/POOR’ dietary compliance were compared with regard to blood pressure (BP) control, antihypertensive drug treatment requirement (ADTR), and anthropometry. Results: Data from four FAIR/POOR diet compliers and three GOOD compliers, as at 29 weeks of dietary intervention, showed mean systolic home BP values of 128.1 (±6.74) mmHg and 122.3 (±2.03) mmHg, respectively; the mean systolic automated office BP values were 139.8 (±8.80) mmHg and 108.3 (±5.55) mmHg, respectively; as at 39 weeks of dietary intervention, the mean ADTR scores were 4.2 (±2.12) and 1.03 (±0.57), respectively. Using data at baseline and from all available timepoints after dietary intervention, two-way ANOVA confirmed highly significant improvement of BP control (P &lt; 0.0001) and reduction of ADTR score (P = 0.0008) in GOOD compliers. GOOD compliers exhibited significantly more reductions in BMI, abdominal circumference, and triceps skinfold thickness than FAIR/POOR compliers (two-way ANOVA and linear regression: P &lt; 0.05). Conclusion: These results support the case for adverse dietary exposure avoidance to abate the phenotypic expression of chronic disease.

Peanut Allergy in Children-Is Prevention Better than Cure?

Peanut allergy, one of the most frequently occurring allergies, usually starts in childhood and rarely subsides-often persisting throughout adult life. Accidental exposure to peanuts can often result in adverse reactions ranging from mild to life-threatening, such as anaphylactic shock. Historically, food avoidance and the use of rescue drugs have remained a fundamental management mechanism for dealing with food allergy. However, prevention of adverse reactions to food allergy is playing an increasing role. This is possible through the early introduction of peanuts into the diet, especially in infants at risk of this allergy. In recent years, specific immunotherapy has been used to develop desensitisation and, in some patients, tolerance-defined as a persistent state of clinical non-reactivity to the allergen after therapy is finished. The aim of this article is to summarise the current state of knowledge on the prevention and treatment of peanut allergy, with a focus on clinical trials, current guidelines, and recent experimental studies. This review may be particularly useful for paediatricians and general practitioners.

The impact of a whole foods dietary intervention on gastrointestinal symptoms, inflammation, and fecal microbiota in pediatric patients with cystic fibrosis: A pilot study

Gastrointestinal (GI) complications are a significant source of morbidity for people with cystic fibrosis (PwCF). Historically, dietary recommendations in CF have focused on calories, typically emphasizing a high fat diet. The changing landscape of CF highlights the need to update this nutritional strategy. There is little research into how the quality of calories consumed by PwCF influences nutritional outcomes, GI symptoms, or likely contributors: intestinal inflammation and GI microbiology. We assessed the feasibility of a whole foods-based diet (WFD) and avoidance of ultra-processed foods, measuring safety/tolerability, adherence, and GI symptoms, as well as fecal measures of inflammation and microbiota among children with CF (CwCF) with GI symptoms. Single center, 4-week dietary intervention involving CwCF aged 5-14 years who screened positive on GI symptom questionnaire. Assessments included weight, symptom questionnaires and adverse events (AEs). Stool was analyzed for microbiota (16S rRNA) and calprotectin. 108 children were pre-screened, 9 enrolled and 8 initiated and completed the study. There were no significant changes in weight and no AEs. PEDS-QL GI identified overall improvement in symptoms. Certain symptom domains (constipation, diarrhea, gas/bloating, stomach pain and hurt) demonstrated significant improvement on the WFD. Of two participants with abnormal fecal calprotectin at enrollment, both exhibited decreased values on WFD. There was no significant change in microbiota diversity. A WFD diet was feasible and safe in CwCF. There was improvement in GI symptom scores based on both parent and child assessments. Larger studies are needed to further investigate effects on intestinal inflammation and microbiota.

Personalized Nutrition for Obesity Management: A Mini-Review

Abstract Obesity is a pro-inflammatory state and a chronic health condition, which falls within the spectrum of immune-mediated inflammatory diseases (IMIDs). It is caused mainly by the consumption of excess calories and egregious food substances. A Personalized Food Avoidance Dietary Approach for Management of IMIDs (PFA-DAMI) addresses primary and secondary immune intolerances of different individuals to dietary constituents. Exposure to toxic food substances is responsible for inflammatory immune dysfunction that mediates obesity. Hence, a PFA-DAMI is promising for the management of obesity. T cell dysfunction disease mediating models describing inflammatory disease processes underlying IMIDs exist. However, they do not highlight inflammatory processes underlying the diseases concerning toxin-mediated epigenetic T cell dysfunction. Online searches were conducted on databases, such as Google Scholar, PubMed, Biomed Central, and SciELO. Articles were reviewed using keywords, such as obesity, personalized nutrition, immune optimization/dysfunction, T lymphocyte activation/dysfunction, cytokines, and adipokines. There is a putative T cell toxin-mediated dysfunction disease model for IMIDs, which may apply to other diseases. The putative disease model may highlight the actual inflammatory immune dysfunctional processes underlying T cell disease mediation in inflammatory diseases, which may be validated by multiomic studies. Validation of the putative disease model using obesity as an example should pave the way for a better understanding of the role of personalized nutrition in obesity management.

Olfactory performance and odor liking are negatively associated with food neophobia in children aged between 3 and 9 years

BackgroundChild food neophobia, i.e., rejection or avoidance of novel foods at a young age, is a prevalent nutrition problem that affects the quality of children’s diet and impedes the development of healthy food preferences. Sensory sensitivity can relate to the degree of food neophobia, but previous studies rarely focused on the olfactory component of this problem in children.ObjectiveWe aimed to thoroughly examine the relationship between various aspects of olfactory sensitivity and food neophobia in children.Methods246 children aged between three and nine years took part in a food neophobia assessment as well as in a comprehensive, psychophysical olfactory testing.ResultsWe found that certain smell perception aspects such as lower odor liking, poorer odor identification ability as well as lower sensitivity to an unknown non-food odor all significantly predicted higher food neophobia in children. Among individual characteristics of either a child or a caregiver, only the child’s age significantly and positively predicted food neophobia. The exploratory model looking into the role of family environment factors predicting self-reported food neophobia in children revealed that food neophobia was associated with lower control given to a child in this child’s feeding process, as well as with a more frequent use of food as a reward in feeding.ConclusionsWe suggest that suppressed olfactory perception and performance can play a unique role in child nutritional difficulties. The study inspires further considerations of olfaction-engaging interventions to counteract food-neophobia in children.

Development and Management of Avoidant/Restrictive Food Intake Disorder and Food Neophobia in Pediatric Patients with Food Allergy: A Comprehensive Review.

Avoidant/Restrictive Food Intake Disorder (ARFID) and food neophobia present significant challenges in pediatric healthcare, particularly among children with food allergies (FAs). These eating disorders, characterized by the persistent avoidance or restriction of food, can lead to severe nutritional deficiencies and psychosocial impairments. The presence of FAs further complicates these eating behaviors, as the fear of allergic reactions exacerbates avoidance and restrictive patterns. This comprehensive review synthesizes current knowledge on ARFID and food neophobia, focusing on their definitions, characteristics, and the unique challenges they present in the context of FAs. The review explores the critical role of healthcare professionals, especially nurses, in integrating psychological and clinical care to improve outcomes for affected children. A multidisciplinary approach, including Cognitive Behavioral Therapy (CBT) and Family-Based Therapy (FBT), is emphasized as essential in addressing the complex needs of these patients. The review also highlights the need for standardized treatment protocols and further research on the long-term outcomes of these disorders, aiming to enhance therapeutic strategies and family support systems. Effective management of ARFID and food neophobia in the context of FAs requires a holistic and integrated approach to mitigate the profound impacts on a child's growth, development, and overall well-being.

THE ROLE OF LIFESTYLE-RELATED TREATMENTS FOR IRRITABLE BOWEL SYNDROME

Introduction: The role of diet and lifestyle in Irritable Bowel Syndrome (IBS) mainly involves alleviating symptoms and improving the quality of life for patients. Diet plays a significant role through the identification and avoidance of trigger foods, the introduction of an appropriate amount of fiber, and adherence to specific guidelines. Lifestyle, including regular physical activity, stress reduction techniques, and healthy sleep habits, also contributes to the reduction of bowel discomfort. Aim of the study: The aim of this study is to examine the relationship between diet and lifestyle, and the occurrence and course of Irritable Bowel Syndrome. Material and Methods of Research: A literature review focused on keywords related to the topic was performed using databases such as PubMed and Google Scholar, as well as textbooks and articles on websites. Results: Irritable Bowel Syndrome (IBS) is a chronic functional disorder of the gastrointestinal tract, primarily characterized by abdominal pain and changes in bowel habits. Dietary modifications, such as a lowFODMAP diet, and lifestyle factors, including physical activity levels, stress management, and meal regularity, significantly influence the course of the disease. There are gender differences in symptomatology and psychosocial impact as well as gender-specific responses to pharmaceutical treatments. Ongoing research is needed to better understand the mechanisms underlying IBS and to optimize therapeutic strategies. Conclusion: The effectiveness of IBS therapy requires a comprehensive approach that includes dietary modifications, increased daily physical activity, learning to manage emotions, and regular collaboration with a doctor. Understanding and implementing these elements are crucial for effectively alleviating symptoms and improving the functioning of patients with Irritable Bowel Syndrome.

Food Neophobia in Children: A Case Study in Federal District/Brazil.

A reluctance to eat and/or avoidance of novel foods is characterized as food neophobia (FN). FN restricts the diet to familiar foods when, in fact, it should be much more varied. FN can be a barrier to healthy foods, affecting the quality of diet, and impairing children's growth and development. Therefore, according to their caregivers' perceptions, this study aimed to evaluate FN in children from Federal District/Brazil. The Brazilian Children's Food Neophobia Questionnaire (BCFNeo), a specific instrument developed and validated in Brazil, was answered by caregivers of children aged 4 to 11 y/o. Sampling occurred through snowball recruitment, being convenient and non-probabilistic. The Health Sciences Ethics Committee approved the study. The analysis evaluated FN in total (BCFNeoTot) and in the following domains: general (FNgen), for fruits (FNfru), and for vegetables (FNveg). FN scores were compared between sex and child's age and categorized according to three ordinal levels. FN levels were compared using the Mann-Whitney U test. The Friedman test, followed by the Wilcoxon test with Bonferroni correction, was performed to analyze differences in FN according to the environment. Of the caregivers' answers for their children, 595 answers were included, because 19 were out of age. The prevalence of high FN was 42.9%. The domain with the highest prevalence of high FN was vegetables (48.6%). Children aged 8 to 11 y/o had a higher mean FN in two domains (FNgen p = 0.047 and FNveg p = 0.038) when compared to children aged 4 to 7 y/o. Boys were more neophobic in all domains (FNgen p = 0.017; FNfru p = 0.010; FNveg p = 0.013; BCFNeoTot p = 0.008), and FN tends not to decrease with age. The results showed that the children of the FD are more neophobic than Brazilian children in general, highlighting the importance of additional studies in FN determinants in this population and nutritional education interventions to reduce FN among FD children.

Food Neophobia and Avoidant/Restrictive Food Intake among Adults and Related Factors.

Avoidant/restrictive food intake disorder (ARFID) includes age-inappropriate feeding behaviors in eating patterns, including food neophobia, defined as refusal or reluctance to eat new or unknown foods. This study aimed to assess the prevalence of ARFID and food neophobia among adults and determine the related characteristics of these risks. The study used an anonymous survey questionnaire consisting of three parts as the research tool. The first part of the questionnaire was a metric and concerned socio-demographic data. The Food Neophobia Scale (FNS) and the Nine-Item Avoidance/Restrictive Food Disorder Screen Questionnaire (NIAS) were used to evaluate the eating disorders. The survey included 309 people (60.2% women, 39.8% men) aged 18-77 years. NIAS results indicated that 15.2% of the subjects showed food selectivity, and 11.0% had food anxiety. In the FNS assessment, 42.4% had a low risk of food neophobia, 38.2% a medium risk, and 19.4% a high risk. A higher risk of food neophobia correlated with higher NIAS scores, indicating a higher risk of ARFID (p = 0.00231). The NIAS score increased with the risk of food neophobia (p = 0.000). Respondents at low risk of neophobia were most likely to avoid several products (83.97%), while in the high-risk group, 56.67% did not want to eat a favorite food enriched with a new ingredient. A higher risk of neophobia was correlated with more food avoidance and adverse reactions to new foods (p = 0.000). A higher risk of food neophobia is strongly correlated with a higher risk of ARFID. Although demographics did not significantly impact NIAS results, some trends were noted, such as higher scores among older and underweight people. Those with a higher risk of food neophobia show more food avoidance and a greater reluctance to experiment with new ingredients. Public education should emphasize that eating disorders affect both sexes equally, with tailored interventions for high-risk groups such as the elderly, rural populations, and those with lower education. Health policies should promote access to nutrition education, psychological support, and diverse food options, while further research is needed to improve targeted interventions.

Living with and Caring for People with Multiple Food Allergies: A Qualitative Study.

The quality of life (QoL) impact of food allergies extends beyond severe allergic reactions, as food avoidance can permeate the daily lives of individuals with food allergies and their caregivers. People with multiple food allergies may experience a greater impact on QoL than people with a single food allergy, but there is limited evidence available. The aim of the study was to provide insight into the lived experiences of adults, teenagers, children, and caregivers of children with multiple food allergies. Semi-structured interviews were conducted of people with multiple food allergies and their caregivers (n = 20) in the United States, including 10 adults, 5 teenagers, and 5 caregivers of children. Patterns in responses were explored using reflexive thematic analysis. Four themes were developed by the researchers to convey the experiences of people with food allergies and QoL impact: preparedness and allergen avoidance results in a loss of spontaneity; emotional impact varies by person and for each person; participating in society involves speaking up and trusting others; and food is more than nutrition. In addition, 3 themes were identified that convey the experiences of caregivers: looking out for your child's safety is an emotional balancing act; limitations on what you can do on your own and as a family; and creating a safe and fulfilling environment can be time-consuming and costly. These findings highlight that people with multiple food allergies experience social limitations, stress about food safety and allergen avoidance, and restrictions on freedom. Caregiver QoL is impacted by the need to navigate social, emotional, and practical implications of caring for a child with multiple food allergies.
