If a person has a known allergy to which citrus fruits should they approach yuzu with caution?
Answer
Oranges, lemons, or grapefruits
While yuzu itself may not be a frequent allergen, it belongs to the broader *Citrus* family, meaning cross-reactivity is a distinct possibility for sensitive individuals. If someone has a documented allergy to other common citrus fruits, such as oranges, lemons, or grapefruits, introducing yuzu requires careful observation. This caution is rooted in the shared biological components within the family that might trigger an adverse immunological response. An allergic reaction, even if rare for yuzu specifically, can manifest through various symptoms ranging from mild dermatological issues to more concerning internal distress.
