Hi,

This is my first post here. I'm really new to peanut allergies. I was wondering if anyone knows if it's possible to be allergic to peanut oil, but not peanut butter?

My Dr. thinks I've developed a peanut oil allergy at age 31. Last week was a pretty bad reaction, hives difficulty breathing, etc... I've had 2 reaction to french fries at Buger King in the last few months. When I asked them what oil they used, they told me they changed to peanut oil a few months ago, right around the time of my first reaction.

I eat peanut butter all the time and have no problems. Has this ever happened to anyone else?

No. My peanut-allergic son eats BK fries just fine and last I checked they are NOT fried in peanut oil. You can actually ask them to bring you a box of their shortening which I believe is soy based. If you can eat peanut butter you are NOT allergic to peanuts.

I would suspect a food allergy for sure. Reactions happen usually within minutes to 45 min of ingestion but can start up to 2 hours after ingestion. I would make a list of all things you ate within 2 hours of both reacctions and bring those foods to an allergist to get skin tested to those very foods.

Also, you should have epi pens and a written, clear emergency plan that spells out when to use the epi if you have another reaction. The reactions you described are VERY serious and untreated can lead to even a fatality.

Do you have an allergist yet? If not now is the time to get one asap.

I would avoid all foods you ate just before the reaction until you know the cause of this. A good allergist will help you figure out the cause of this.

Thanks for the comment. I called our BK again and checked the website. The woman last week was wrong. They use a combo of corn, soy, and canola oil.

I do have a shrimp allergy so I do have an allergist and epi pens.

Hephzibah624-welcome to peanutallergy.com!

To answer your question--food allergies are an allergic reaction to the protein of an allergen.

That being said, if you were allergic to peanuts you would be allergic to peanut protein.

It does sound like the reactions you experienced were allergic reactions of some kind. Unfortunately you might not be able to tell what from.

It's possible that the fries were cross contaminated--meaning they touched something you might be allergic to. Not sure if it could have been shrimp there though.

Most people who are allergic are not allergic to highly refined oils like peanut oil, soybean oil, etc. (Though some are.)

It's also possible you are allergic to sulfites or some other preservative that might be in the fries.

I don't recommend allergy testing when you are not sure about the allergen in question as there is a risk of false positives.

I do recommend discussing with an allergist and not a gen. Dr. and also monitoring what you eat closely for any other symptoms.

Hope that helps!
Ruth

Thank You!

I never even thought of sulfites! Ruth you may have just saved my life, literally! I'm allergic to all sulfer/sulfites/sulfonomides (sp?) in medicine. One reaction hospitalized me for 2 weeks. If I were to guess, that's what it was. I know my Dr. will agree.

We're still going to do the blood test just to see if anything shows, but I know that's not the most reliable.

Thank You so much!

Emme--Yay! So glad to help! Do come back and let us know what you learn. I'd be curious to hear if it is indeed sulfites.

Not me, and this is quite strange because most cases I've heard of deal with the PA sufferer being tolerant to peanut oils because they are so highly refined...

I've never heard of this. I am allergic to both peanuts, peanut butter, and peanut oil :/

Sad to say that's the way it is for me too. Anything peanut related in fact.

If you're suffering an allergic reaction to something cooked in or containing peanut oil, it's not because of the oil. The allergic reaction comes from peanut proteins, but highly refined peanut oil doesn't contain them. Major restaurant chains across the U.S.A. cook with peanut oil due to its high smoke point and other favorable properties, and they wouldn't do it if there were even a chance that it would harm people with food allergies.
