Efficacy and effects of black teaAssist digestion and degreaseIn black teacoffeeAlkali, vitamins, amino acids, phospholipids, etc. help the human body to digest and regulate fat metabolism. The stimulating effect of caffeine can increase the secretion of gastric juice, thereby increasing appetite and helping digestion.Japanese scholars have proved through scientific inspection that blackTea setIt has a strong function of relieving greasy and digesting food, which is why the carnivorous people particularly like this tea.
    The food structure of the ethnic minority people in Northwest China is beef, lamb and cheese.teaThe effect of “removing fatness” and “resolving fishy meat” has a lot to do.
In addition, black tea can also improve the intestinal microbial environment and has the function of smoothing the intestines and stomach.The Chinese folks have a tradition of using old black tea to treat abdominal distension, dysentery, and inability to digest.    
Reduce fat and lose weightHigh blood lipid content can cause lipids to be deposited on blood vessel walls, causing atherosclerosis and thrombus formation.Black tea has good fat degradation, anti-blood coagulation, promote fibrinogen dissolution and significantly inhibit platelet aggregation. It can also relax the blood vessel wall and increase the effective diameter of the blood vessel, thereby inhibiting the atherosclerotic plaque on the inner wall of the aorta and coronary arteries. form.Achieve the purpose of lowering blood pressure, softening blood vessels, and preventing and treating cardiovascular diseases.    The rich tea polysaccharides in black tea have the effect of reducing blood lipids and peroxide activity in the blood.From May 1990 to May 1991, the General Hospital of the Chinese People’s Liberation Army conducted observations on 55 hyperlipidemia patients among 155 senior cadres in a retreat after taking black tea for 180 days (3 grams per day). In 50 cases of drinking black tea, the blood lipid content and blood peroxide activity decreased significantly.
    anti-oxidationThe free radical theory of aging believes that under normal physiological conditions, free radicals in the human body are constantly produced and removed, and they are in a balanced state.Dark tea is not only rich in antioxidants such ascatechuWhitekind,Tea pigment, Flavonoids, vitamin C,Vitamin E, D-carotene, etc., and contains a large amount of anti-oxidant trace elements such as zinc, manganese, copper (the constituent element of SOD) and selenium (the constituent element of GSHPX).The catechins, theaflavins, and theaflavins in black teaTheanineAnd tea polysaccharides, especially the more complex flavonoids, have the function of scavenging free radicals, so they have the effect of anti-oxidation and delaying cell aging.
Cancer is currently one of the diseases that cause extremely high human mortality in the world.    Since the late 1970s, scientists from all over the world have discovered that tea or tea extracts have an inhibitory effect on the occurrence of a variety of cancers.Hunan Agricultural University used the cutting-edge high-throughput screening technology of modern drug screening to conduct high-throughput screening research on the tumor cell model SGC7901 of black tea, which proved that black tea has a significant inhibitory effect on tumor cells.
hypotensiveIt has long been reported that tea has the effect of lowering blood pressure.Japan reported that the unique amino acid theanine in tea can inhibit the increase in blood pressure by activating dopaminergic neurons.Here, it was also found that the caffeine and catechins in tea can relax blood vessel walls, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation.China Lou Fuqing and others found that tea pigments have significant anticoagulant, promote fibrinolysis, prevent platelet adhesion and aggregation, and inhibit the proliferation of arterial smooth muscle cells. It can also significantly reduce triglycerides and low-density lipoproteins in the serum of high-fat animals. High-density lipoprotein in the serum has a significant inhibitory effect on the ACE enzyme and has a blood pressure lowering effect.    HypoglycemicThe tea polysaccharide complex in black tea is the main component for lowering blood sugar.Tea polysaccharide complex is usually called tea polysaccharide, which is a kind of complex and highly variable mixture.The results of the determination of the tea polysaccharide content of several teas show that the tea polysaccharide content of black tea is the highest, and its component activity is also stronger than other teas. This is because in fermented tea, due to glycosidase, protease, and hydrolase Because of the formation of relatively short sugar chains and peptide chains, short peptide chains and longer peptide chains are easier to absorb and have stronger biological activity. This may be the reason that fermented tea, especially black tea, has an excellent blood sugar lowering effect. One of the reasons for other teas.
    Sterilization and anti-inflammatoryThe main components of black tea soup color are theaflavins and thearubigen.Studies have shown that theaflavins are not only an effective free radical scavenger and antioxidant, but also have obvious antibacterial effects on botulinum, Enterobacter, Staphylococcus aureus, Perfringens, and Bacillus cereus.In addition, theaflavins have a certain inhibitory effect on the invasion of influenza virus and the infection of rotavirus and enterovirus.
Diuresis and detoxificationThe diuretic function of caffeine in black tea is achieved by the kidneys to promote the filtration rate of water in the urine.At the same time, the stimulating effect of caffeine on the bladder can not only assist in diuresis, but also help sober up alcohol and relieve alcohol toxins.At the same time, the black teaTea polyphenolsNot only can the nicotine of tobacco be precipitated and excreted with urine, but also the free radicals in the smoke can be eliminated, and the toxic effect of smoke on the human body can be reduced.For heavy metal poisons, tea polyphenols have a strong adsorption effect, so drinking more tea can also alleviate the toxic effects of heavy metals.    The medicinal value of dark teaBlack tea has the effects of quenching thirst, anti-radiation, anti-cancer, anti-cancer, helping sober up, promoting digestion, weight loss, delaying aging, and lowering cholesterol.It can enhance the acuity of brain central nervous activity, improve thinking ability, lower blood pressure, inhibit arteriosclerosis, etc.
    Tea belongs to post-fermented tea. Its unique processing process, especially the participation of microorganisms, makes it have special traditional Chinese medicine and pharmacological effects. It is rich in tea polysaccharide compounds and is considered by the medical community to regulate glucose metabolism in the body (prevent diabetes) and lower blood lipids. , Blood pressure, anti-coagulation, thrombosis, improve body immunity.Clinical trials have proved that the special effects of black tea are remarkable, and it is irreplaceable for other teas.Through the use of high-throughput screening technology, 10 modern disease models were selected, and the functions of black tea on human health were studied, including models for lowering blood pressure, lowering blood lipids, and lowering blood sugar, models for inhibiting the spread of cancer cells, and models for improving human immunity. Wait.Through model evaluation, it is found that Qianliangcha and Fuzhuan are effective in lowering blood pressure, lipids, and blood sugar, and are very helpful for human fat metabolism and weight control.In addition, the extract of Qianliangcha has an inhibitory effect on the spread of gastric cancer cells and liver cancer cells.Hundreds of years of history have proved that it is the drink of life for herders in the border areas.Nowadays, with the changes in people’s lifestyle and diet, more and more fat intake and milk consumption, drinking black tea is more and more necessary.due toFu Brick TeaThere is a unique blooming process, which produces a kind of Santocystis cristatum, which produces a kind of punuol component during the fermentation process, which oxidizes excess cholesterol in the body and prevents fat accumulation. Dr. Wang Zhiwei, a world-class microbiologist, researches microorganisms and The food has been fermented for 18 years, and it is said that Fuzhuan tea is the most amazing food in the world.
