Answer

Hypersensitivity to foods is a problem encountered throughout the industrialized world. [8] In the United States, an estimated 4 million Americans have well-substantiated food allergies. A study from Australia showed that more than 10% of 12-month-old children had challenge-proven IgE-mediated food allergies. [9] In Montreal, 1.5% of early elementary school students were found to be sensitized to peanuts. Reactions to foods are thought to be the most common prehospital (outpatient) cause of anaphylaxis.
