Background: Food allergy has become an increasingly important public health problem. However, information regarding epidemiological studies of food allergy among Chinese adults is very limited. This study aims to estimate the prevalence of self-reported food allergy among adults in China.
Method: A population-based cross-sectional study was administered to estimate the prevalence of self-reported food allergy on the basis of a face-to-face questionnaire survey. The participants were recruited by cluster random sampling from three prefectures in Jiangxi Province, China.
Results: A total of 12 082 questionnaires were distributed, and 11 935 (98.8%) of completed ones were collected. The prevalence of self-reported food allergy was 4.0% (3.1% in men and 4.8% in women), self-reported doctor-diagnosed food allergy accounted for 1.4%. The most common allergic symptom was skin reaction showing in 63.9% of the participants with self-reported food allergy. The main allergic foods were shrimp, mollusks, and mango, accounting for the prevalence of 39.8%, 20.8%, and 18.7%, respectively. The self-reported food allergy was significantly linked with gender, age group, body height and other allergic conditions.
Conclusions: The prevalence of self-reported food allergy is about 4.0% among adults in China. The three most common allergenic foods were shrimp, mollusks and mango. Gender, age, and other allergic diseases could be contributing factors associated with food allergy in adults. These findings will provide scientific basis for the further research and prevention of food allergy in adults.

Roads to remission: evolving treatment concepts in type 2 inflammatory diseases.
EClinicalMedicine
February 2025
Institute of Laboratory Medicine and Pathobiochemistry, Molecular Diagnostics, Philipps University Marburg, Marburg, Germany.
Unlabelled: Non-communicable diseases (NCDs) characterised by type 2 inflammation, including asthma, allergic rhinitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis, food allergies and eosinophilic esophagitis, are increasing in prevalence worldwide. Currently, there is a major paradigm shift in the management of these diseases, towards the concept of disease modification and the treatment goal remission, regardless of severity and age. Remission as a treatment goal in chronic inflammatory NCDs was first introduced in rheumatoid arthritis, and then adopted in other non-type 2 inflammatory diseases.

Background: Multiparameter immunoblot testing is increasingly used as an alternative to multiple individual IgE analyses for type 1 allergies. This study investigated the performance of an inexpensive immunoblot method, the RIDA qLine allergy test system (R-Biopharm AG), vs. the current gold standard.

Objective: We aimed to determine whether a pro-inflammatory dietary pattern (mechanism-based diet) is associated with incident female gout among two large cohorts of US women.
Methods: We prospectively followed 79,104 women from Nurses' Health Study (NHS; 1984-2016) and 93,454 women from NHSII (1991-2017); 45,445 men from Health Professionals Follow-up Study (1986-2016) served as a comparison cohort. Validated food frequency questionnaires were used to calculate Empirical Dietary Inflammatory Pattern (EDIP; food-based index predictive of circulating inflammatory biomarkers) scores every 4-years.
A review of the toxicological effects and allergenic potential of emerging alternative protein sources.
Compr Rev Food Sci Food Saf

The growing environmental pressure of the animal food chain requires a system shift toward more sustainable diets based on alternative protein sources. Emerging alternative protein sources, such as faba bean, mung bean, lentil, black gram, cowpea, quinoa, hemp, leaf proteins, microalgae, and duckweeds, are being explored for their potential in meeting global protein demand and were, therefore, the subject of this review. This systematic literature review aims to understand the current knowledge on the toxicological effects and allergenic potential associated with these sources and derived protein and food products.

Tropomyosin (TM), the primary allergen in crustacean aquatic products, has excellent thermal and digestive stability. In this work, the changes in digestive resistance of TM and allergenicity of TM digestion products induced by ultrasound-assisted cold plasma (UCP) treatment were investigated. The stability of TM to simulated digestion were reduced, especially the simulated intestinal fluid (SIF) digestive resistance.
