Give celery a second look. A satisfyingly crunchy snack, it adds flavor to soups, salads and stews. A medium stalk has only six calories, plus small amounts of potassium, vitamin C, folate, fiber and lutein (a carotenoid). It has 32 milligrams of sodium—not much, though more than most vegetables.
However, chewing celery does not result in a net loss of calories, as some people claim. Eating celery won’t subtract inches from your waistline, but at least it won’t add any.
