According to the study by the American Heart Association journal Hypertension, blood pressure decreased about 10 mm Hg in high blood pressure patients who drank a cup of beet root juice daily. The reason given: Beet root juice contains dietary nitrate, which may help relax blood vessel walls and improve blood flow.Beets are good for you – they are rich in folate, potassium, vitamin C, fiber and antioxidants. They are just not a solution in themselves. I join researchers in encouraging you to eat more green leafy vegetables as part of a broader lifestyle approach – which ultimately will improve your cardiovascular health.
