Medical value of tea polyphenol: it has anticancer effect

Tea polyphenols have high medical value and anticancer effect 1 It can eliminate the active oxygen free radicals, block the lipid peroxidation process, and improve the activity of enzymes in human body, so as to play the role of anti mutation and anti-cancer Many medical experiments have proved that tea polyphenols have a strong role in eliminating harmful free radicals and preventing lipid peroxidation; inducing the increase of metabolic enzyme activity in human body, promoting the interpretation of carcinogens; inhibiting and blocking endogenous nitrosation in human body, preventing carcinogenesis and radical mutation It can inhibit the covalent binding of carcinogens and cell DNA, prevent DNA single strand breakage, and improve the cellular immune function of the body The results showed that 160 mg tea polyphenols per person per day inhibited and blocked the nitrification process in human body, and 480 mg tea polyphenols had the highest inhibition 2 Prevention and treatment of diseases caused by hyperlipidemia: ① enhance the strength and toughness of microvasculature, reduce blood lipid, and prevent liver and coronary atherosclerosis The effect of tea polyphenols on serum cholesterol is to clear the accumulation of cholesterol on the arterial wall by increasing the content of high-density lipoprotein cholesterol (HDL-C), and to inhibit the uptake of low-density lipoprotein cholesterol (LDL-C) by cells, so as to reduce blood lipid, prevent and alleviate atherosclerosis ② lowering blood pressure: one of the functions of human kidney is to secrete "angiotensin II" which can increase blood pressure and "bradykinin" which can reduce blood pressure, so as to maintain blood pressure balance When the enzyme activity that promotes the conversion of these two substances is too strong, the level of Ang Ⅱ increases, and the blood pressure increases Tea polyphenol has a strong inhibitory effect on the activity of invertase, so it can reduce or maintain the stability of blood pressure ③ hypoglycemia: diabetes mellitus is the metabolic disorder of sugar, fat and protein caused by insulin deficiency and excessive blood sugar Tea polyphenols can regulate the glucose metabolism of human body, reduce the level of blood sugar, thus effectively prevent and treat diabetes ④ prevention of stroke: One of the causes of cerebral apoplexy is that lipid peroxide is generated in human body, which makes the blood vessel wall lose elasticity Tea polyphenol has the function of restraining lipid peroxide, keeping the elasticity of blood vessel wall, relaxing the blood vessel wall, eliminating vasospasm, increasing the effective diameter of blood vessel, reducing blood pressure through vasodilation, so as to effectively prevent cerebral apoplexy ⑤ antithrombotic: the increase of plasma fibrinogen can cause the aggregation of red blood cells and the increase of blood viscosity, thus promoting the formation of thrombus In addition, the increase of phospholipid and cholesterol in the membrane lipid will reduce the deformability of red blood cells, seriously affect the perfusion of microcirculation, increase the blood viscosity, make the blood flow in capillaries stagnate, and intensify the aggregation of red blood cells and thrombosis Tea polyphenols can protect and repair the deformability of red blood cells, and can easily form complex with thrombin to prevent fibrinogen from turning into fibrin In addition, tea polyphenols can effectively inhibit the increase of cholesterol content in plasma and liver, promote the excretion of lipids and bile acids, and effectively prevent the formation of thrombus Most of the existing antithrombotic drugs have some side effects and are not easy to take for a long time Tea polyphenol is a kind of natural component in tea, which has the function of reducing blood fat and resisting thrombus In addition, it has its own antioxidant properties, which makes it a new functional health care product.
