How common is a peanut allergy?
<|assistant|>
In the United States, approximately 1.8 percent of adults and 3.5 percent of children are allergic to peanuts. In addition, roughly 0.9 percent of adults and 2.3 percent of children have a moderate-to-severe peanut allergy, where exposure to peanuts can cause a severe allergic reaction, such as anaphylaxis. It is the most common food allergy in young children and affects girls and boys almost equally. Peanut allergy is less common among non-white populations and among adults, especially those over age 45.
