When it comes to food allergies, nuts are often the subject of the most persistent myths. While managing a peanut allergy shares some similarities with tree nut allergy management, many people will be surprised to learn about the differences between them. However, understanding the distinctions is a crucial step towards obtaining an accurate diagnosis along with ongoing care from your Atlanta allergist. So what are the main differences between a peanut and tree nut allergy?
What Makes Peanut and Tree Nut Allergies Different?
From the underlying cause of the allergy to the treatment approach, peanut and tree nut allergies are distinct in many ways. Let’s look at what sets peanut allergies and tree nut allergies apart.
Severity of Allergic Reactions
Peanut and tree nut allergies share some common symptoms including stomach pain, hives, swelling and difficulty breathing. However, peanut allergies are more likely to cause severe allergic reactions. According to the Mayo Clinic, peanuts are the most common food allergy-related trigger for anaphylaxis. A study published in the National Library of Medicine further identifies peanuts as the leading cause of fatal food-induced anaphylaxis.
Peanut and Tree Nut Classifications
The word “nut” in peanut understandably leads to a bit of confusion when discussing allergies. The peanut is actually not a nut at all, but a legume that grows underground. In contrast, the nuts that are most likely to cause allergies (almonds, Brazil nuts, cashews, hazelnuts, pecans, pistachios and walnuts), grow on trees. When dealing with this and any type of food allergy, accurate food allergy testing procedures are needed to diagnose exactly what is triggering a reaction.
Dietary Differences Between Peanuts and Tree Nuts
Both peanuts and tree nuts are found in a wide range of snacks, sauces and baked goods. However, the types of foods you’ll need to watch out for will vary. Peanuts are common in candy, chocolate and peanut butter, while tree nuts are often found in breakfast cereals and savory dishes.
Chances of Cross-Reactivity
Cross-reactivity occurs when different foods (that contain similar proteins) trigger an immune system reaction. And while peanuts typically don’t cause cross-reactivity with other legumes like soy and lentils, people who react to one type of tree nut often react to several others.
Onset of Allergy Development
Peanut and tree nut allergies can develop at any time during a person’s life. However, peanut allergies often emerge in early childhood, particularly in infants and toddlers. Tree nut allergies are more likely to develop later in childhood, and can even appear in adulthood. At the first sign of symptoms you should speak with your allergist about peanut and tree nut allergy treatment and testing.
