Celery

If you associate celery with diets, or think the stalks are nothing more than sturdy swizzle sticks for your Bloody Mary, think again. Evidence suggests there’s a world of health benefits in every crunch. Dieters count on celery because it’s low in calories—only 10 calories in a large stalk—but it also delivers phthalides, which are thought to act as a natural diuretic. Those same phtalides support the circulatory system, and can help to reduce high blood pressure.
