Peanut allergy is caused by an allergic reaction to the peanut protein. Peanut oil is typically safe because it's highly refined and has almost no detectable allergen (protein). This is the type of peanut oil often used in cooking and frying and is safe for individuals with peanut allergy.

Should you consider peanut oil/peanut allergy the same? The short answer is no, because there is no such thing as a peanut oil allergy. If you are allergic to peanuts, you are allergic to the protein in peanuts, which is removed from highly refined peanut oils, but is still present in unrefined peanut oils.

Infants with severe eczema and/or egg allergy have a higher risk of being allergic to peanuts, but it is now known that earlier introduction of peanut-containing foods reduces the subsequent risk of developing a peanut allergy.

Peanut preparation (dry roasted vs. boiled or fried), delayed consumption of peanuts in young children, genetic factors, skin adaptations caused by regular bathing that lets peanut proteins penetrate the skin, changing agricultural methods and a weakened immune system may all be to blame.

But peanuts are common, and despite your best efforts, you're likely to come into contact with peanuts at some point. For a severe allergic reaction, you may need an emergency injection of epinephrine and to visit the emergency room. Many people with allergies carry an epinephrine autoinjector (EpiPen, Auvi-Q, others).

Palforzia is the only oral immunotherapy product currently approved by the FDA for treatment of peanut allergy. This type of treatment is called oral peanut immunotherapy. It slowly exposes an allergic child to peanuts so their immune system is less likely to react after an accidental ingestion of peanut product.

Very often the answer is: vegetable oil. If you have a peanut allergy, this may sound safe enough. However, while vegetable oil most often means canola, corn, or soy-based oil, in some rare cases peanut oil may be in the mix. This is because peanuts are not actually nuts - they're legumes!

Sesame oil does contain sesame protein and should be avoided. Also, one should be cautious with some less commonly found unrefined nut oils – including flax, walnut, almond and sunflower. In most cases, if the oil is highly refined, it will be safe for a person who is generally allergic to the food.

Research has shown that refined peanut oil will not cause allergic reactions for the overwhelming majority of people who are allergic to peanuts and if anyone does suffer a reaction it is likely to be mild. However, unrefined (crude) peanut oil is more likely to cause symptoms.
