What causes tolerance to spicy or sour foods?
In: 49
I know spiciness is just exposure rather than any genetic component.
Not sure about sour though.
I do know anecdotally that I’ve loved sour even as a small child. My mom tried to give me a lemon as a baby, just to get the puckered “oh hell no” reaction out of me, and instead I loved the hell out of it. And as an older child, I’d eat so much sour stuff that the acids in it would wear away a few layers of my tongue. My mom doesn’t like sour, but my dad has always been fond of it.
