Tree Nut Allergies
A tree nut allergy is caused by the seeds and nuts coming from trees. Like peanut allergies, it is a very common health problem. Some popular tree nuts include almonds, cashews, Brazil nuts, pistachios, macadamia nuts, walnuts, and pine nuts. People with this type of allergy can also have problems with products containing these ingredients like nut oils or butter. Since symptoms can become serious, it is advisable to avoid all nuts if you are allergic to only one type.[4]
