What does pickle juice do to the body?
Anecdotal evidence indicates that the juice, which is combined with cucumbers to make pickles, has helped professional football players lessen cramping when competing in hot weather, the Vanderbilt University research notes. Despite claims of pickle manufacturers, little scientific evidence supports the use of the juice as an athletic drink to prevent muscle cramps and dehydration. Salt can help with dehydration but does not have to come from pickle juice, according to the director of the Sports Medicine Center at Vanderbilt University.
