It may be good for your heart

Zucchini has a good amount of potassium: 295 milligrams per cup, or 8 percent of your recommended daily value. According to the American Heart Association, potassium can help control blood pressure because it lessens the harmful effects of salt on your body. Studies suggest that boosting your potassium intake (while also curbing sodium) can slash your stroke risk and may also lower your odds of developing heart disease. Zucchini is also high in the antioxidant vitamin C, which may help the lining of your blood cells function better, lowering blood pressure and protecting against clogged arteries. One cup of sliced zucchini has 20 milligrams, or about 33 percent of your daily value.
