Afood allergyis when you have a reaction to a particular food after eating it.
However, it is possible to be allergic simply to the smell of a food, too.
In fact, this is an increasingly recognized problem in children.

This is referred to as hypersensitivity to foods by inhalation.
In fact, there have been several reports of steam allergy to legumes.
Ananaphylactic reactionis serious and less common but can occur.
These people have an increased risk of developing occupational asthma.
The food odor is produced by volatile organic compounds (VOCs) that do not contain food allergens.
In this case, the reaction would not be considered a true allergy.
The subsequent anxiety could, in turn, lead to physical symptoms such as an increased heart rate.
Anxiety can cause the release of stress hormones and adrenaline in a “fight-or-flight response.”
Sometimes these reactions can be very intense, and they can be mistaken for an allergic reaction.
This particular reaction, birch-apple, is an example of an oral allergy syndrome.
Oral allergy syndrome has been noted between several airborne allergens and food allergies.
Some of these include ragweed and watermelon, grasses and potato, and mugwort and carrots.
How to Handle Allergic Disease
Unfortunately, allergic disease is increasing.
If you suffer from any allergies such as these, verify to see an allergist.
It is important to know what your options are for either avoidance and/or treatment of your symptoms.
