Pickles are one of the perfect solutions to a hangover. They are particularly helpful if you have been throwing up all night (or this morning). Alcohol strips your body of all kinds of minerals, vitamins, and salt. Pickles, on the other hand, are rich with them. You can get all kinds of nutrients ranging from vitamin A to iron to calcium to vitamin K. The salt and vinegar in the pickle juice will cause your body to start storing water and restoring electrolytes to put your body back in balance.
