The obvious solution: Don't eat them.

It's a sensitivity rather than an actual allergy. I have the same thing with peanut butter, only mine strikes in the lower GI tract, which is a bit more socially challenging. Peanuts don't seem cause the problem, but the truth is, I can live without peanuts and peanut butter. I never liked PB as a kid and maybe my body was wiser than my adult appetite.

Most of the food sensitivity theories will tell you to stay absolutely away for three months, and then gradually try eating them again if you want, but be aware that there may be some threshold that if you eat more than that, you'll get the symptoms back.

Or you can spend $1200 for the Elisa blood test and find out what else you're sensitive to.
