A roadhouse nut allergy is not the same as a tree nut allergy.
A tree nut allergy is an allergy to a tree nut, such as almonds, cashews, pistachios, and walnuts. Tree nuts contain proteins that are similar to those found in shellfish. People with tree nut allergies react to these proteins with an immune system that produces antibodies, or proteins that mark the person’s body as harmful.
The proteins that cause reactions in tree nut allergy sufferers are similar to proteins that cause allergic reactions in people with a peanut allergy. The proteins are called tree nut allergens.
The roadhouse nut allergy is different from a peanut allergy.
A peanut allergy is an allergy to peanut, and it’s possible to have a peanut allergy, but not an allergy to peanuts.
Symptoms of a peanut allergy include swelling of the skin, hives, and/or difficulty breathing. The symptoms of a roadhouse nut allergy are similar to those of a peanut allergy, but they’re milder in nature.
A roadhouse nut allergy doesn’t increase the risk of other types of allergies.
If you have a peanut allergy and have been diagnosed with a roadhouse nut allergy, you should avoid eating foods that contain peanuts and nuts, including:
- Peanut butter
- Peanut oil
- Peanut and nut butters
- Peanut and nut meal
- Peanut-based spreads
- Peanut-in-shell snacks
- Nuts and nut butters
- Nut-based snacks
- Nut butters
- Nuts and oil
Diagnosing a roadhouse nut allergy
To diagnose a roadhouse nut allergy, your doctor will do a skin prick test. A skin prick test is a simple blood test. During it, the doctor pricks the skin over the part of the body that’s causing the symptoms. The test involves placing a tiny amount of the allergen onto the skin and then waiting 24 to 48 hours to see if there is an allergic reaction.
If you’re allergic to a tree nut, you may have a positive skin prick test. If you have a positive skin prick test, your doctor may order a blood test to confirm that you have a roadhouse nut allergy.
The skin prick test can be done in two ways.
In one way, the skin prick test can be done using a small amount of a tree nut extract. This is called a skin-prick test with a prick to the skin. It can show if you have an allergy to a tree nut, including roadhouse nuts.
If you have a positive skin-prick test with a prick to the skin, your doctor may order a blood test to confirm that you have a peanut allergy.
If your blood test results are negative, your doctor may order a food challenge to see if you have a food allergy.
If your blood test results are positive, your doctor will order another skin prick test to see if you have a positive reaction to a different tree nut.
Food challenge test
The food challenge test is not a standard test performed in an allergy clinic. It’s a test that must be ordered by your doctor, and it consists of:
- Taking a food to see if you have an allergic reaction to it
- Waiting a certain amount of time
- Checking for symptoms of an allergic reaction
The food should contain the same allergen that you had a positive reaction to in the test with the skin prick. The food used for the food challenge should contain a tree nut, but not a peanut.
A positive food challenge to a different tree nut may show that you have a roadhouse nut allergy.
Treating a roadhouse nut allergy
There is no cure for a roadhouse nut allergy.
Allergy medications can help relieve symptoms and prevent them from occurring in the future.
Avoiding foods that contain peanuts and tree nuts can help prevent allergic reactions.
The best way to avoid a roadhouse nut allergy is to avoid foods that contain peanut or tree nuts.

If you have a peanut allergy, you can still eat nuts. And, if you have a peanut allergy, you can eat peanut butter, peanut oil, and peanut-based foods.
