you ask a very interesting question and i can see where you're coming from. after all mold is a fungus and mushrooms are fungi so if a person is allergic to one type of fungus wouldn't they be allergic to all fungi? fortunately the answer is "no. " or at least "not necessarily. " when we talk about a "mold allergy " we're usually talking about a nasal allergy (also called an 'inhaled allergy'). that means when we breathe in mold spores our immune system treats them like an invader and mounts a hyperactive attack to get rid of them. that hyperactive attack leads to the common symptoms of nasal allergies: sneezing runny nose swollen nasal passages and more. however most people don't inhale mushrooms. most people eat them. when you eat something your stomach acid starts breaking it down quite quickly. while it's possible to have a true food allergy (peanuts is a particularly lethal example) most of the time the immune system does not view food as an invader. even if you had a nasal allergy to mold and then you ate mold you likely would not have an allergic reaction to it. you might get good and sick from eating mold but that wouldn't be due to a hyperactive immune response in your nasal passages. it's a good thing that one type of allergy doesn't always translate to being allergic across the board. for example most people who are allergic to penicillin can still safely consume blue cheese -- which is created by injecting cheese cultures with penicillium. it would be a shame if everyone who was allergic to penicillin was denied the creamy luxury of a good blue cheese. wishing you well!
if mold is a microscopic fungi does that mean a person allergic to mold might be allergic or sensative to mushrooms?
