I have no idea how any kind of peanut might affect an allergy, for good or ill. What I do know is that I’ve been eating roasted and salted peanuts pretty much my whole life, and I’m now in my 70s. Good stuff. But then, I don’t have an allergy.
I feel for those with a peanut allergy. I think about how many different types of nuts I eat, not to mention one of my favorite sammiches...the PBJ. A PBJ sammich gives me a needed boost when I’m working in the yard.
My son has almost died twice from ingesting peanuts.
