Why do some things (like peanuts) have so many people allergic to them while other things (like mint) aren’t causing issues to nearly as many?
Basically why are some things more allergenic than others

It has to do with your genes.
Your immune system has a sensing system,one gene (HLA) codes for and thus programs your immune system to be able to detect any foreign particle entering your body. Certain variants of HLA (alleles) (copies which have the same function but with slight differences) have the setting where they detect peanuts to be microbial and thus raising the alarms on your body and prepping for a cellular war which you experience as wheezing,coughing,redness etc.
