Storage proteins: Seeds, legumes, and nuts all contain storage proteins. They are similar and you can have cross reaction between all of them. So if you are primarily allergic to cashew (which is a tree nut), you may also react to peanut (a legume), or even sesame seed (a seed).

Avoid peanuts: Currently, the only treatment for peanut allergy is strict avoidance, having self-injectable Epinephrine available, a written anaphylaxis action plan and wearing a medical ID. Reading food labels and being aware of cross contamination is key. An allergist can assist in discussing prognosis and future treatments.
