Severe Cashew Allergy Symptoms: Understanding Cross-Reactivity and Co-Reactivity

Cashews, a popular nut, can trigger severe allergic reactions in some individuals. However, it's not just food products containing cashews that can cause an allergic reaction. Cashew is also found in non-food items, making it essential to scrutinize labels diligently. In this article, we'll explore the severity of cashew allergies and the concept of cross-reactivity and co-reactivity.

Food manufacturers may modify ingredients or change facilities, increasing the risk of cross-contamination. This means that even if you've previously consumed a particular product, it's crucial to check the label again. Cashews can be hidden in various products such as nut butters, oils, extracts, milk, and some beverages. They're also often used as a substitute for pine nuts in pesto recipes.

Unlike other tree nut allergies, pollen allergy or hay fever is rarely associated with cashew nut allergy. If you're concerned about cross-reactive foods, consult your doctor or allergy specialist. The major cross-reactive foods include pink peppercorns, sumac spice, citrus fruits and pips, peaches and plums, and mango and its seed.

Surprisingly, people with cashew allergies can also react to other non-tree nut foods. In addition, those with cashew nut allergy may experience reactions to peanuts and other tree nuts that do not come from closely related plant species. Tree nut allergies and peanut allergy often involve reactions to various nut types.

The main related allergen to cashew is pistachio, which is highly cross-reactive. Understanding the concept of cross-reactivity and co-reactivity is vital when dealing with nut allergies. Tree nuts include almonds, Brazil nuts, cashews, macadamia nuts, pistachios, pecans, walnuts, hazelnuts, and pine nuts (classified as tree nuts in the US).

Cashew nut allergies are common in both children and adults and can be severe. It's essential to take necessary precautions and consult a healthcare professional if you suspect an allergy. By being aware of the severity of cashew allergies and the risks of cross-contamination, you can better manage your condition and live a healthy life.
