ELI5: Why do you crave salty/fried foods after drinking alcohol?
gpt
Did you know, if you attempted to run a marathon drinking only water, you could die. Shocking, huh?

Water is exceptionally important to human bodies but it doesn't work alone. Salts help this water get to where it needs to be and helps water do what it needs to do. Drinking alcohol dehydrates you, and that dehydration means your precious salts went out with the piss. Your body wants more back in there!
