Tea can control High Blood Pressure, Preventing Cardiovascular Disease in CKD

Cardiovascular disease is the leading cause of death among hemodialysis patients, and poorly controlled blood pressure is a major risk factor for cardiovascular events. Also, high blood pressure remains one of the most common causes of Chronic Kidney Disease (CKD) and contributes to development of End-Stage Renal Disease (ESRD).

A high blood pressure reading is one that exceeds 140/90 millimetres of mercury. The first figure, the systolic pressure, corresponds to the ‘surge’ that occurs with each heartbeat. You might have thought you were simply satisfying a thirst, but researchers say that drinking three cups of tea a day may also stabilize your blood pressure, reduce it, and minimize the variability of blood pressure readings taken at night.

Experts say the benefits of tea are largely due to flavonoid content, antioxidant ingredients, that counteract cardiovascular disease.  It has long been known that high blood pressure can significantly increase the risk of heart disease. Now wide variations in blood pressure are also recognized as an important risk factor compared with blood pressure readings that show little difference over a 24-hour period.

There is already mounting evidence that tea is a contributor to a healthy heart, but this is an important discovery because it demonstrates a link between tea and a major risk factor for heart disease. This shows that the consumption of black tea lowers rates of blood pressure variation at night time. Research also suggests adding milk does not affect the benefits.

High blood pressure is a well-recognized risk factor for cardiovascular and total mortality. Traditionally the level of blood pressure has been equated with risk but the variability of blood pressure is now thought to contribute to the risk. Black tea and its constituent flavonoids are increasingly associated with improvement in blood pressure and cardiovascular health. The regular consumption of black tea has been shown to lower blood pressure. Therefore, KidneyBuzz.com recommends drinking three tea cups of black tea each day according to your fluid intake requirements.
