These included both cashew nut allergic and cashew nut sensitized children. Subjects were identified based on a positive IgE (≥0.35 IU/L) to cashew nut in children younger than 18 years. The aim of this study was to investigate the clinical characteristics of cashew nut allergy in Singaporean children.Ī retrospective analysis was conducted between 20 in KK Women's and Children's Hospital, the main tertiary paediatric referral centre in Singapore. An estimated prevalence of self-reported tree nut allergy in Singapore in 2010 was 0.3%. There have been no Asian studies looking specifically into cashew nut allergies. A study in Leicester comparing White children with South Asian children found the latter to be more likely to be sensitized and allergic to cashew nuts, with a relative risk of 1.94 and 2.59 respectively. Cashew nut is commonly consumed in Singapore and in Asia as a snack, as well as used in Indian, Thai, and Chinese cuisines. In Sweden, a 10-year review estimated the prevalence of cashew nut allergy to be 6% of their food allergy cohort, with evidence of increasing frequency and severity of cashew nut allergic reactions. In the United States, cashew nut and walnut allergies are the most common tree nut allergies accounting for 15%–30% of all tree nut allergies. Just as the prevalence of peanut allergy is on the rise in Western populations, recent studies suggest a similar trend for cashew nut allergy. It is protected by a double-layered hard shell that is toxic and requires processing prior to consumption. The kidney-shaped cashew nut sprouts out externally from the cashew fruit. occidentale is cultured in Africa and Asia.
