Maybe That’s Not an Allergy

Food Allergies Less Common Than Believed, says a study.  How they did it:  Disguised food and placebos (e.g., peanut butter hiding in something else or something else dressed up as peanut butter).

[T]he true incidence of food allergies is only about 8 percent for children and less than 5 percent for adults…[y]et about 30 percent of the population believe they have food allergies.

Not addressed:  How many of those non-allergy allergies are due to stress?
