Abstract: Cashew nut allergy can cause serious food allergy. In recent years, with the rapid increase in consumption of cashew nuts, the incidence of cashew nut allergy has been on the rise, and cashew nuts have become an important food allergen. Ingestion of a small amount of allergens can cause severe allergic reactions and even life-threatening events. However, cashew nut allergy is a severely underestimated health problem, especially for children. Therefore, the society urgently needs to pay enough attention to cashew nut allergy, and it is necessary to widely publicize the seriousness of cashew nut allergy to the public. This article conducts a systematic review on the epidemiology, allergen components, clinical features, diagnosis, prevention and treatment of cashew nut allergy, with the aim to provide scientific information for the social understanding and in-depth research of cashew nut allergy.
