Cashews Now Leading Cause of Tree Nut-Induced Anaphylaxis in Children: Study
Cashews have emerged as the most common cause of tree nut-induced anaphylaxis in children, according to a recent study published in The Journal of Allergy and Clinical Immunology (JACI). The analysis, which spanned data from 2007 to 2024, revealed a striking increase in allergic reactions to cashews, particularly among children under the age of five (Nguyen-Luu et al., 2024).
Researchers found that even tiny amounts of cashew — often less than a teaspoon — were enough to trigger severe reactions. The study observed that, unlike other tree nuts, cashews are more likely to be introduced to children at an early age through processed foods, spreads, or mixed nut products, potentially contributing to the higher sensitization rates.
The rise in cashew-induced anaphylaxis outpaced that of other tree nuts like almonds, walnuts, and pistachios. The findings stress the need for pediatricians and caregivers to be cautious during early food introductions, especially in children with a family history of food allergies.
The study also underlines the importance of food labeling and allergy awareness. With cashew being used widely in both sweet and savory packaged products, accidental exposure is becoming more frequent — especially in daycare and school environments.
