1. Replaced Electrolytes
Celery contains high levels of potassium and sodium. This makes it perfect for replacing electrolytes lost during exercise. One benefit of chomping on celery instead of swigging an artificially flavored electrolyte beverage is you avoid excess sugar and artificial colors. Whip up a post-workout green smoothie containing celery, apple, spinach, banana, and avocado for a delicious way to recover from exertion.
