Tree nuts Allergy.
Tree nuts are a common food allergy: in the United States, about 0.5% of the population—or about one in every 200 people is allergic to tree nuts. Tree nuts frequently cause strong allergic reactions and may cause anaphylaxis, which is a potentially life-threatening allergic reaction.
It’s possible to be allergic to just one type of tree nut, but many people are allergic to multiple different types of tree nuts. In addition, it’s common for food manufacturers to process different types of tree nuts on the same equipment, raising risks for people who are allergic. Therefore, if you have a tree nut allergy, your doctor may warn you to avoid most or all tree nuts.
Types of Tree Nuts.
The most common tree nuts include macadamia nuts, brazil nuts, cashews, almonds, walnuts, pecans, pistachios, chestnuts, hazelnuts (filberts), and pine nuts (pignoli or pinon). Less common tree nuts include beechnuts, butternuts, chinquapins, gingko, hickory nuts, lychee nuts, pili nuts and shea nuts.
Children who are allergic to multiple types of tree nuts (more than one or two) are less likely to outgrow their allergy than children who are allergic to just one type of tree nut.
