What are the benefits of drinking tea

summary

Tea has many pharmacological effects and wide range of functions, which can not be replaced by other drinks. The main components of tea with pharmacological effects are tea polyphenols, caffeine, lipopolysaccharide, etc. Today, I'd like to introduce the benefits of drinking tea.

What are the benefits of drinking tea

First, it is helpful to delay aging. Tea polyphenols have strong antioxidant and physiological activities, and are scavengers of free radicals in human body. According to the research of relevant departments, it has been proved that 1 mg of tea polyphenols can eliminate excessive free radicals harmful to human body, which is equivalent to 9 μ g of superoxide dismutase (SOD), much higher than other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes.

Second, it is helpful to inhibit cardiovascular disease, and tea polyphenols play an important role in human fat metabolism. The content of cholesterol and triglyceride in human body is high, and the deposition of fat in the inner wall of blood vessels, the formation of atherosclerotic plaque after the proliferation of vascular smooth muscle cells and other cardiovascular diseases. Tea polyphenols, especially the catechins ECG and EGC in tea polyphenols and their oxidation products theaflavins, help to inhibit the proliferation of the plaque, reduce the fibrinogen with enhanced blood coagulation viscosity, clear blood coagulation, and inhibit atherosclerosis. 　　

Third, it is helpful to prevent and fight cancer. Tea polyphenols can block the synthesis of ammonium nitrite and other carcinogens in the body, and have the effect of directly killing cancer cells and improving the immune ability of the body. According to relevant data, tea polyphenols (mainly catechins) in tea are beneficial to the prevention and adjuvant treatment of gastric cancer, colorectal cancer and other cancers.

matters needing attention

Tea polyphenols and their oxidation products have the ability to absorb the toxicity of strontium 90 and cobalt 60. According to the clinical trials of relevant medical departments, the effective rate of tea extract in the treatment of mild radiation sickness caused by tumor patients in the process of radiotherapy can reach more than 90%; the effective rate of tea extract in the treatment of hemocytopenia can reach 81.7%; and the effect of tea extract in the treatment of leukopenia caused by radiation is better.
