This causes an allergic reaction. Even a small amount of peanut or tree nut protein can set off a reaction. But allergic reactions from breathing in small particles of nuts or peanuts are rare. That's because the food usually needs to be eaten to cause a reaction.
Most foods with peanuts in them don't allow enough of the protein to escape into the air to cause a reaction. And just the smell of foods containing peanuts won't cause one because the scent doesn't contain the protein.
When someone with a peanut or tree nut allergy has something with nuts in it, the body releases chemicals like histamine. Reactions to foods, like peanuts and tree nuts, can be different. It all depends on the person — and sometimes the same person can react differently at different times. Nut and peanut allergies can cause a severe reaction called anaphylaxis.
Anaphylaxis may begin with some of the same symptoms as a less severe reaction, but then quickly get worse, leading someone to have trouble breathing, feel lightheaded, or to pass out. If it is not treated right away, anaphylaxis can be life-threatening.
If you have a peanut or tree nut allergy or any kind of serious food allergy , the doctor will want you to carry an epinephrine auto-injector in case of an emergency. An epinephrine pronounced: eh-puh-NEH-frin auto-injector is a prescription medicine that comes in a small, easy-to-carry container.
It's easy to use. Your doctor will show you how. Keep the epinephrine with you, not in a locker or in the nurse's office. Every second counts in an allergic reaction. If you start having serious allergic symptoms, like swelling of the mouth or throat or trouble breathing, use the epinephrine auto-injector right away. Also use it right away if your symptoms involve two different parts of the body, like hives with vomiting.
Then call and have someone take you to the emergency room. The proteins aren't present in purified peanut oil, which is fat, not protein. That's why most people who are allergic to peanuts can consume peanut oil without a reaction. Those specific proteins also aren't present in the airborne compounds that create the odor of peanuts. The smell is contained in smaller organic compounds that aren't peanut protein.
You inhale and potentially ingest these flavor and aroma compounds when you smell peanuts, but since they don't contain the problematic proteins, you won't react to them. Medical researchers have tested the peanut odor for allergic reactions. They exposed 30 children with peanut allergies to peanut butter and a soy butter placebo for 10 minutes each at a range of one foot.
Although the subjects could smell the peanut butter and the soy butter , none of them reacted to the peanut butter aroma. Many of these children had a history of contact-based or inhalation reactions to peanuts. Reactions that appear to involve the smell of peanuts in the air are really about what you're actually inhaling. Peanut dust and small airborne peanut particles can cause an allergic reaction.
If all you're smelling is peanut butter, it's unlikely any dust or small pieces of peanut are floating in the air. Peanut butter is sticky, not dusty. One exception is if you're smelling peanut butter near a nut-butter grinder, like some upscale grocery stores and health food stores have. These machines pose a real risk and you should stay away. If people are shelling and eating peanuts near you, they can spread peanut dust in the air.
That means you could not only be smelling peanuts but actually inhaling dust and particles. Dust inhalation is an issue at stadiums that serve peanuts and in some stores and restaurants that offer unshelled peanuts for customers to snack on.
In addition, when foods are cooked, they often release oils into the air—oils that can contain allergenic proteins and cause reactions. Boiled peanuts , or certain types of Asian foods that include peanuts and peanut sauce, could pose this risk. Finally, trace amounts of peanut products can get onto your hands and be ingested that way, causing a reaction, even if there's no peanut dust in the air.
Many airlines still serve peanuts on planes and patients are self-reporting subjective reactions to peanuts. A recent study showed that the only way peanut allergen would show up in the air of a commercial plane is if the peanuts were boiled or removed from the shells, so just serving peanuts on a plane should not cause an anaphylactic reaction.
Nevertheless, it would be better if planes did not serve peanuts as many patients have a great fear. A study was done taking 30 children with severe peanut allergy. They were either exposed to peanut butter by inhalation or by touching peanut butter.
None of the 30 children experienced a systemic or respiratory reaction. An allergic reaction to food will not occur because someone is eating it in a classroom or vicinity of the allergic person. He does go on to say that if everybody on an airplane started opening packages of peanuts, then that could be a concern:.
The only exception to the above is if peanut protein itself is in the air that you breathe. If a peanut allergic person breathes enough of the peanut protein in the air, the person can have a serious allergic reaction, asthma attack or anaphylaxis. Situations in which this are unusual but can happen. For instance, if a large number of people are opening packages of peanut at the same time — e.
So, this would justify an airline opting to not serve peanuts to all passengers on an airplane. Myth 3: Touching peanuts or a peanut-contaminated surface can trigger an allergy. Certainly, prolonged skin contact with peanuts can trigger an allergic reaction. People treated for peanut allergies using special skin patches often will develop rashes. However, brief contact is unlikely to cause anything, unless some peanut particles are eaten or inhaled or come into contact with the eyes.
