Blue cheese tastes like vomit to some people because of the high levels of butyric acid that the blue cheese contains.
Some people love the taste of blue cheese and find it doesn't taste like vomit or taste bad at all.
But I'm also one of the people that thinks blue cheese tastes like vomit and just tastes very bad in general.
My mom loves blue cheese but when I tried it I found it tasted awful and couldn't stomach it and I actually did almost vomit as a result of trying to swallow the blue cheese.
Blue cheese is a moldy type of cheese and it's not for everyone but it's healthy when eaten but not everyone likes blue cheese or any other foods for that matter.
My mom could eat blue cheese all day long while I spit out just one bite of blue cheese and cannot eat it because it just tastes awful to me.
