There are several risk factors associated with developing an allergy to cashews. They include: Allergy to another type of tree nut: Tree nuts often have high cross-reactivity, which is when two different foods have similar enough proteins that cause allergic reactions.

Cashew allergy: An allergic reaction to cashew nuts. Cashew allergy can be isolated, meaning that the individual is only allergic to cashews and not to other nuts, or the allergy may extend to other kinds of tree nuts such as walnuts and pistachios.

Cashew food allergy is associated with the presence of IgE directed against the major seed storage proteins in cashew, including the 13S globulin (legumin group) and 2S albumins, both of which represent major allergen classes in several plant seeds.
What foods to avoid if you are allergic to cashews?
The most common cross-reactivities with cashews are plant foods, e.g., tree nuts, fruits, soybeans, vegetables, and legumes. Cashews and pistachios share similar allergenic proteins, so those who react to cashews may also react to pistachios and vice versa.
How do you test for cashew allergy?
The cashew allergy blood test checks for an allergic reaction to cashews by assessing the level of the IgE antibodies in the blood. Preparation: No special preparation required.
Why do cashews make me sick?

When applied to the skin: There isn’t enough reliable information to know if cashew is safe. If the unroasted cashew is used it might cause skin irritation, redness, and blisters.
Cashew, pistachio, and mango are in the same family, so shared proteins is common as is cross-reactivity. A number of other foods contain proteins similar to those in cashews. For this reason a person with a cashew allergy may also react to hazelnut, mustard seed, peanut, pistachio, sesame, soybean, and walnut.
Can I eat cashews if I’m allergic to peanuts?

Walnuts, almonds, pistachios, and pecans are also seeds of drupes — just like cashews ( 5 ). Cashews are usually classified as nuts because they possess many of the same physical and nutritional characteristics as true nuts.
Why are so many people allergic to nuts?
The reason for the response is an overactive immune system that identifies proteins in the peanut as a threat. An antibody called immunoglobulin E is produced which causes chemicals to be released. The result is an allergic reaction – one that could potentially be life-threatening.
Is a cashew a tree nut?

In addition, four persons reported perianal itching, and three reported blistering of the mouth.
What is a high IgE level for cashew allergy?
Based on their study, they conclude that a value of greater than 0.97 kU/L of Ana o 3 IgE testing, there is a high likelihood of a positive food allergy to cashew.
Are cashews inflammatory?
Taken together, our result fits with previous study in which it was demonstrated that cashew nuts possess interesting anti-inflammatory, anti-oxidative, and analgesic activities that will be of interest for further investigation.
