Why is effective
The secret is found in green tea is rich in polyphenols, especially epigallocatechin gallate, a powerful antioxidant.
It is made from the leaves of the plant Camellia sinensis. The leaves are steamed, which prevents the EGCG compound being oxidized. By contrast, black and oolong tea, which come from the same plant, are made from fermented leaves, which results in the EGCG that is converted into other compounds that are not as effective in preventing and fighting various diseases.
How is low blood pressure (BP)?
It allows blood vessels to relax. Tea has caffeine, but unlike coffee, it really relaxes and the blood vessels and lowers blood pressure naturally, without side effects.
ACE, one of the causes of hypertension, is inhibited
Studies show that green tea catechins, EGCG, in particular enzyme (ACE conversion of angiotensin), which causes small muscles around the arteries to remove, which makes the smaller arteries, the forcing to increase your blood pressure. (Source: Actis-Goretta L, et al .. Inhibition of the activity of angiotensin-converting enzyme-rich foods J Agric Food Chem flavanols January 2006, 54: 229-34). If green tea can do naturally, why take an ACE inhibitor ramipril and artificial.
Salt uptake is blocked
Laboratory tests have shown that salt intake in green tea blocks the intestine that leads to lower BP. Theanine also a tea protein, lower blood pressure in genetically hypertensive rats but not in normal cells. (Source: Kreydiyyeh SI, et al: The tea extract inhibits intestinal absorption of glucose and sodium in rats Comp Biochem Physiol Pharm Tox endocrine July 1994, 108: 359-365 ..). That is good news for those of us who are genetically predisposed to hypertension.
Reducing the risk of hypertension in middle-aged
Recent research, following an eight-year study showed that middle-aged people who drank more than 600 ml of green tea each day had a 65% lower risk of developing hypertension. People who drank 110ml and 600 ml of each day for over a year showed an 46% lower risk of blood pressure.
People who do not drink or who drank less than 110 ml per day had no protection against hypertension.
This protection against the development of hypertension by drinking tea does not show statistically that after a year of daily use. In the short-term human trials have been inconclusive.
Considering all the evidence, green tea is more effective in reducing blood pressure, if we take four or five cups of green tea each day. “Better to be deprived of food for three days, than tea for one” (old Chinese). Being part of the diet of green tea can help lower blood pressure naturally.
