1. Helps to delay aging.
Tea polyphenols have strong oxidation resistance and physiological activity, and are scavengers of human free radicals. According to the research of relevant departments, the effect of 1 mg tea polyphenols on eliminating excessive free radicals harmful to human body is equivalent to 9 micrograms of superoxide dismutase (SOD), which is much higher than other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes. According to the test results of Tomoyo in Ota, Japan, it is confirmed that the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin E.
2, help to inhibit cardiovascular disease.
Tea polyphenols play an important role in human fat metabolism. The human body has cardiovascular diseases such as high cholesterol and triglycerides, such as fat deposition on the inner wall of blood vessels and atherosclerotic plaques formed after vascular smooth muscle cells proliferate. Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and its oxidation products theaflavins, are helpful to inhibit this mottled proliferation, reduce the formation of fibrinogen that enhances coagulation viscosity, make coagulation clear, and thus inhibit atherosclerosis.
3, help to prevent and fight cancer.
Tea polyphenols can block the synthesis of carcinogens such as ammonium nitrite in the body, which can directly kill cancer cells and improve the immunity of the body. According to relevant data, tea polyphenols (mainly catechins) in tea are beneficial to the prevention and adjuvant treatment of cancers such as gastric cancer and intestinal cancer.
4. It is helpful to prevent and treat radiation injury.
Tea polyphenols and their oxidation products have the ability to absorb the toxicity of radioactive substances strontium 90 and cobalt 60. According to the clinical trials of relevant medical departments, the treatment of mild radiation sickness caused by radiotherapy with tea extract can reach more than 90%. For cytopenia, the effective rate of tea extract is 865438 0.7%; It has a good therapeutic effect on leukopenia caused by radiation.
5, help to inhibit and resist viruses and bacteria
Tea polyphenols have strong convergence, obvious inhibition and killing effects on pathogenic bacteria and viruses, and obvious anti-inflammatory and antidiarrheal effects. Many medical units in China use tea preparation to treat acute and chronic dysentery, amebic dysentery and influenza, and the cure rate is about 90%.
6, contribute to beauty and skin care
Tea polyphenols are water-soluble substances, which can remove greasy face and astringe pores, and have the effects of disinfection, sterilization, anti-aging and reducing the damage of ultraviolet rays in the sun to the skin.
7, help to refresh.
Caffeine in tea can stimulate the central nervous system of human body, enhance the excitement process of cerebral cortex, and has the functions of refreshing the brain, clearing away heart fire and calming the nerves.
8, help diuresis to relieve fatigue
Caffeine in tea can stimulate the kidney, promote the rapid excretion of urine, improve the filtration rate of the kidney and reduce the retention time of harmful substances in the kidney. Caffeine can also eliminate excessive lactic acid in urine, which helps to eliminate fatigue as soon as possible.
9, help reduce blood fat and help digestion.
It is recorded in the Tang Dynasty that the effect of tea is "eating for a long time makes you thin". There is a saying among the ethnic minorities in China's border areas that "tea is indispensable for a day". Because tea helps digestion and reduce fat, in today's fashionable language, it is helpful to "lose weight". This is because caffeine in tea can increase the secretion of gastric juice, help digestion and enhance the ability to decompose fat. The so-called "long-term eating makes people thin" is here.
10, which helps to protect teeth and improve eyesight.
The fluorine content in tea is high, and the fluorine content per 100 g of dry tea is 100 mg- 15 mg, of which 80% is water soluble. If everyone drinks 10g tea every day, they can absorb 1mg- 1.5mg of water-soluble fluoride. Moreover, tea is an alkaline beverage, which can inhibit the reduction of calcium in the human body, help prevent dental caries, protect teeth and strengthen teeth. According to relevant data, the experiment of "gargling with tea after drinking" among primary school students can reduce the incidence of dental caries by 80%. According to the investigation of relevant medical units, 28.6% cataract patients have the habit of drinking tea; 7 1.4% have no habit of drinking tea. This is because vitamin C and other ingredients in tea can reduce the turbidity of eyes, and drinking tea often has a positive effect on reducing eye diseases, protecting eyes and improving vision.
