Uh. Spicy food is oily. You need to wash it down with fatty stuff. Whenever I have too much hot shit in my mouth, milk never does anything because I only have skim milk. I always take a swig of olive oil, some bread, mush it all around in my mouth, then spit it out. That always does the trick.
guess its a good thing i drink only vitamin d whole fat milk?
If a given food has some possible health benefits, then it is not specifically because it is spicy.
Alcohol is not healthy simply because there are some reported benefits from red wine.
If could be specific ingredients, perhaps something part of a specific flavouring and needs to be carefully considered on a per-food basis since even multiple foods called the same can vary considerably.
