I know that urine drinking is a widespread practice (with a long history). The main reason that people give today involves there being nutrients in urine.
If there are nutrients to be gained, why is it that the body is getting rid of them in the first place? Is it just that the body didn't need them "at the moment"? If so, is "at the moment" likely to change within a 24 hour period (I'm thinking of daily urine drinkers here)?
Note: I am not interested in water or the adverse effects of drinking a high salt solution (hence, the dilute urine). Also, if this question doesn't belong here, feel free to edit/close.
