Not great. They are certainly not great as an adult. In children what we do see is that the younger you are when you develop the allergy, the more likely it is that it will be outgrown. I would simply avoid it, and follow your ige levels to peanut to see if someday, you might be able to do a food challenge (if the ige level dropped).
Not likely. As an adult it is highly unlikely that one would "outgrow" a peanut allergy.
