Celery:
Celery is an excellent food that digests well with almost anything else. It contains the necessary mineral sodium, which is present in a ratio that can be easily accessed by the body. Sodium is critical, along with the mineral potassium, in managing the body's electrolyte balance.
Electrolytes create electric osmotic pressure which helps the body to move fluids through the cell's membranes. It can be eaten with any other fruit or vegetable.
