Modern research on the efficacy of Pu 'er tea * * * lists these 20 operations, namely, weight loss, lipid lowering, prevention and treatment of arteriosclerosis, prevention and treatment of coronary heart disease, blood pressure lowering, anti-aging, anti-cancer, blood sugar lowering, antibacterial and anti-inflammatory, smoke poisoning reduction, heavy metal reduction, radiation resistance, central nervous system excitement, diuresis, dental caries prevention, eyesight improvement, digestion assistance, anti-toxicity, sterilization, constipation prevention, hangover relief and others. Some functions are as follows. Here is a brief introduction to the functions and mechanisms of the main substances in tea. \ x0d \ x0d \ 1, Weight loss and lipid lowering and prevention and treatment of atherosclerosis \ x0d \ x0d \ Tea polyphenols can obviously inhibit the increase of cholesterol and triglycerides (both main components of blood lipids) in the body, promote the excretion of lipid compounds from feces, and make the capillary wall elastic, so it is very important to prevent and treat atherosclerosis, hypertension and obesity. \ x0d \ x0d \ Obesity is mostly caused by metabolic disorder and excessive accumulation. The weight-reducing effect of tea is due to the comprehensive effect of effective components such as tea polyphenols, chlorophyll and vitamin C. \ x0d \ x0d \ Tea polyphenols can remove fat and greasy, chlorophyll can hinder the digestion and absorption of cholesterol, and vitamin C can promote the excretion of cholesterol, so drinking tea can achieve the ideal weight loss effect. \ x0d \ x0d \ Hypolipidemic (also called hypolipidemic) refers to reducing the content of cholesterol in blood and preventing hyperlipidemia (or hyperlipidemia). Because obesity often leads to an increase in cholesterol at the same time, the slimming effect of tea is also effective in lowering blood fat. \ x0d \ x0d \ Tea polyphenols in tea can not only remove fat, but also significantly inhibit the increase of cholesterol content in plasma and liver, and inhibit the prevention and treatment of arteriosclerosis. Professor Lou Fuqing and other studies show that tea pigment (oxidized from catechin) has obvious anticoagulant effect, promotes fibrinolysis, prevents blood from being stimulated, arrogant and poor, and prevents coronary heart disease. Therefore, drinking tea is effective in preventing and treating coronary heart disease. According to statistical data, the incidence of coronary heart disease without drinking tea is 3. 1%, while those who drink tea occasionally are reduced to 2.3%, and those who drink tea regularly (for more than three years) are only 1.4%. In addition, the aggravation of coronary heart disease is related to coronary insufficiency and thrombosis. The tea pigment formed by the continuous oxidation of catechins and tea polyphenols in tea polyphenols during boiling has obvious anticoagulant, fibrinolytic and antithrombotic effects in vitro animal experiments. \x0d\\x0d\3。 Decreased blood pressure \ x0d \ x0d \ Hypertension refers to the increase of systolic or diastolic blood pressure, which exceeds the normal level. Atherosclerosis not only leads to coronary heart disease, but also has a close relationship with hypertension. Lowering blood pressure means lowering blood pressure. Tea polyphenols, vitamin C and vitamin P in tea are all effective components for preventing and treating hypertension. In particular, the role of capillaries in the pathogenesis of tea polyphenols and the obvious inhibitory effects of catechins and theaflavins on the transformation of angiotensin I can directly lower blood pressure. \x0d\\x0d\4。 Anti-aging \ x0d \ x0d \ The process of lipid peroxidation at rest has been proved to be one of the mechanisms of human aging, and some compounds with oxidation effect, vitamin C, are used. Vitamin e can delay aging. Tea contains not only more vitamins C and E, but also tea polyphenols. Japanese scholars have studied that vitamin E, which has always been regarded as an anti-aging drug, has an antioxidant effect of only 4%, while green tea contains tea polyphenols, and its antioxidant effect is higher than 74%. In addition, amino acids and trace elements in tea also have certain anti-aging effects. \ x0d \ x0d \ 5。 Anti-cancer \ x0d \ x0d \ Tea anti-cancer refers to the prevention and treatment of various malignant tumors. The Chinese Academy of Preventive Sciences conducted in vivo experiments on 140 kinds of tea. In vitro scientific experiments and the display of a large number of data confirmed the anticancer and antimutagenic effects of tea. It mainly blocks the formation of carcinogenic nitroso compounds in human body. Polyphenols and catechins in tea can activate some carcinogenic enzymes, and facial mask can also directly act on electrophilic final carcinogen metabolites to change their activities, thus reducing the start and promotion of proto-oncogenes and reducing the number of final carcinogens. Compared with a large number of people, it also proves that the incidence of cancer in the capital of tea drinking is low. The latest research shows that chemical adults can also prevent an important molecule in the development of cancer. This means that the anti-cancer ability of green tea is stronger and more diverse than scientists predicted. Crops indirectly kill tumor cells mainly by enhancing the immune function of machines. \x0d\x0d\ 6, help digestion \ x0d \ The combination of caffeine and flavanol in tea can increase the peristalsis of the digestive tract, thus helping the digestion of food. \x0d\7, hangover \ x0d \ x0d \ tea hangover, because the liver needs vitamin C catalyst in the process of alcohol hydrolysis. Drinking tea can supplement vitamin C, which is beneficial to the alcohol detoxification of the liver. On the other hand, the diuretic effect of caffeine in tea leaves alcohol in the state of brain center, thus playing the role of hangover relief. \ x0d \ x0d \ 8, diuretic \ x0d \ x0d \ Modern research shows that caffeine and theophylline contained in tea can increase renal blood flow and inhibit renal tubular water reabsorption, thus playing an obvious diuretic role.
