A new study found most people with a peanut allergy aren't additionally allergic to tree nuts, and that around half of those who tested positive for one tree nut allergy actually had no allergic reaction to other tree nuts in a food test.

The study, which was published online Monday in the Annals of Allergy, Asthma and Immunology, looked at the accuracy of skin and blood tests in diagnosing tree nut allergies in patients with allergies to one type of tree nut who had not eaten other kinds of tree nuts before, according to HealthDay.

About half of those who showed sensitivities to tree nuts in allergy testing did not show a reaction when tested using an oral food challenge, in which sufferers eat increasing amounts of the food while being monitored for allergic reactions over several hours.

Almonds, Brazil nuts, cashews, hazelnuts, pistachios, and walnuts are tree nuts; peanuts are actually legumes.

Allergic reactions to peanuts and tree nuts include rashes and swelling of the face, lips, tongue, and throat, UPI reported. Some patients who are severely allergic can experience anaphylaxis, which can cause trouble breathing and death in severe cases.

About 3 million children and adults in the U.S. have tree nut allergies, HealthDay noted. The study looked at more than 100 people with allergies to at least one tree nut.
