FOOD ALLERGY MYTH

“The smell of peanut butter will cause an allergic reaction in someone with a peanut allergy.”

 

FOOD ALLERGY FACT

The smell of peanut butter is caused by pyrizines, which are not proteins. In most cases it is the proteins that trigger allergic reactions.

 

COMMENTARY:

In a small study conducted on children with peanut allergy, peanut butter was held one foot from the noses of the subjects for ten minutes. None of the children experienced an allergic reaction. The smell that we perceive when someone is eating a peanut product is caused by a volatile organic compound, not a protein.  Proteins are the most common cause of allergic reactions.

Although the above information  is reassuring, respiratory exposure to food allergens can cause allergic reactions.  There have been deaths associated with the inhalation of actively cooked foods.  Take caution with flours, powders and other small particles of food that can go up in the air.
