The leaves and stalks of celery can be used as vegetables, and its seeds can be used as spices. In recent years, large-stemmed and crisp green celery introduced from abroad has become a star at the dining table as a cold dish. When eating rich and greasy food, a few stalks can make the meal feel refreshing and invigorating.
Modern medical research has found that celery can neutralize excess uric acid in the blood and can be used as a dietary therapy for gout patients. British scientists have discovered that eating water celery can partially counteract the damage to the lungs caused by toxic substances in tobacco, and to a certain extent, it has the effect of preventing lung cancer.
However, when people usually eat celery, they often prefer to discard the leaves and keep the stalks. In fact, the nutrient content in celery leaves mostly exceeds that of the stalks. For example, its carotene content is 88 times that of the stalk, vitamin B1 is 17 times higher, vitamin C is 13 times higher, and calcium is 2 times higher.由此可见，食芹菜弃叶，实在是可惜。
