I know that Isotonic drinks contain similar concentrations of salt and sugar as in the human body, which makes the drink feel refreshing. Osmosis and so on. Isotonic drinks are not limited to what is branded as sport drinks - a mix of juice and sparkling water can also be isotonic.
Thus I was wondering, if there could be solid isotonic foods. It should be possible for a type of food to contain similar concentrations of salt and sugar as in the human body right? Does that exist? If so, does it feel as refreshing to eat as it feels to drink isotonic drink? If it doesn’t, why not?
Inb4: frozen isotonic drinks are not the answer I am looking for.
I didn’t think about this, but it makes perfect sense. Somebody else also posted that solid food by definition would require too many carbs and amino acids so that the relation to water and electrolytes can by definition not be isotonic to the human body.
