What is the likelihood for a person who has no known food allergies to spontaneously develop them as an adult?
I’m going to guess entirely possible. I’ve been having some health issues and both Drs I’ve seen asked if I’ve ever been tested. Twice, both times, non allergic. When I told them this, they both made a point of telling me that it doesn’t mean I haven’t developed some since! In fact, I may have to be tested again!
Not merely food allergies, but any allergies can spontaneously develop or disappear at any age.
