The effect and function of brick tea

Brick tea effect

Supplementary dietary nutrition

Black tea contains rich nutrients, the most important being vitamins and minerals, in addition to protein, amino acids, carbohydrates and so on. For the residents of the northwestern region who have no choice of vegetables and fruits in their diets, such as cattle, lamb, and cheese, long-term drinking of Hunan black tea is an important source of their essential minerals and vitamins.

Digestive oily

Black coffee in the caffeine, vitamins, amino acids, phospholipids, etc. help the body digest, regulate fat metabolism, caffeine stimulation can improve the secretion of gastric juice, thereby increasing appetite and help digestion. Japanese scholars have proved through scientific tests that black tea has a strong oily greasy, digestion and other functions, which is why meat-eating people particularly like this type of tea.

The food structure of ethnic minorities in Northwest China is beef, mutton, and cheese. Therefore, there is a saying that “it would rather eat for three days without food and not have one day without tea”. This has the effect that tea can “get fatty” and “destroy”. Big relationship.

In addition, black tea can also improve the intestinal microenvironment, has a gastrointestinal function. There is a tradition in our country that old black tea is used to treat abdominal distention, dysentery, and inefficiency.

Lipid-lowering diet to prevent diseases

High levels of lipids can cause lipids to deposit on the walls of blood vessels, thus causing atherosclerosis and thrombosis. Black tea has a good degradation of fat, anti-hemagglutination, profibrinolytic activity and significant inhibition of platelet aggregation, but also to relax the blood vessel wall, increase the effective diameter of blood vessels, thereby inhibiting the atherosclerotic plaque and atherosclerotic plaque form. To achieve blood pressure, soften blood vessels, prevention and treatment of cardiovascular diseases.

The tea polysaccharides rich in black tea have the effect of lowering blood lipids and peroxide activity in the blood. From May 1990 to May 1991, the General Hospital of the Chinese People's Liberation Army observed 55 hyperlipidemia patients in 155 veteran cadres at a retired institution after taking continuous black tea for 180 days (3 grams per day). In 50 cases of drinking dark tea, blood lipid levels and peroxide activity in blood decreased significantly.

Epidemiological surveys conducted in key tea consumption areas in Xinjiang, Inner Mongolia and Qinghai indicate that long-term drinking of black tea has a good regulatory effect on human blood lipids, blood glucose, blood pressure, and arteriosclerosis, and has a good regulation effect on body weight and body shape. .

Antioxidant anti-aging

The theory of ageing free radicals believes that under normal physiological conditions, free radicals in the human body continue to be produced and are constantly being removed and are in equilibrium. Black tea contains not only rich antioxidant substances such as catechins, tea pigments, flavonoids, Vitamin C, vitamin E, and D carotenoids, but also contains a large number of trace elements with antioxidant effects such as zinc and manganese. Copper (a constituent element of SOD) and selenium (a constituent element of GSHPX) and the like. The catechins, theaflavin, theanine and tea polysaccharides in black tea, especially the more complex flavonoids, etc., have the function of scavenging free radicals, and thus have the effects of anti-oxidation and delaying cell senescence.

Anti-cancer, anti-mutation

Cancer is one of the diseases that cause high human mortality in the world.

Since the late 1970s, scientists all over the world have discovered that tea or tea extracts have inhibitory effects on the occurrence of various cancers. Hunan University of Agricultural Science and Technology adopts cutting-edge high-throughput screening technology of modern drug screening to conduct high-throughput screening studies on black tea in tumor cell model SGC7901, demonstrating that black tea has a significant inhibitory effect on tumor cells.

hypotensive

The role of tea in lowering blood pressure has long been reported. Japan reported that theanine, a unique Amino Acid in tea, acts as an inhibitor of blood pressure by activating dopaminergic neurons. Here, it has also been found that caffeine and catechins in tea can relax blood vessel walls, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation. China’s Lou Qingqing found that tea pigments have significant anticoagulation, promote fibrinolysis, prevent platelet adhesion and aggregation, inhibit the proliferation of arterial smooth muscle cells, and significantly reduce triglyceride and low-density lipoprotein in serum of high-fat animals. Serum high-density lipoproteins, and ACE enzyme has a significant inhibitory effect, with a blood pressure effect.

Hypoglycemic treatment of diabetes

The tea polysaccharide complex in black tea is the main component of hypoglycemia. Tea polysaccharide complex is often referred to as tea polysaccharide and is a mixture of black teas with a complex and variable composition. The results of determination of the content of tea polysaccharides in several kinds of teas show that black tea has the highest tea polysaccharide content and its component activity is stronger than other teas because of the glycosidases, proteases, and hydrolases in fermented teas. The effect of the formation of a relatively short length of the sugar chain and peptide chain is due to the short peptide chain longer peptide chain is more easily absorbed, and the biological activity is stronger, which may be fermented tea, especially black tea polysaccharide polysaccharides excellent hypoglycemic effect One of the reasons for other types of tea.

Sterilization and anti-inflammatory

The main components of black tea color are theaflavin and theaflavin. Studies have shown that theaflavins are not only effective free radical scavengers and antioxidants, but also have significant antibacterial effects against botulinum bacillus, enterobacteriaceae, staphylococcus aureus, capsular bacillus, bacillus cereus. In addition, theaflavins have a certain inhibitory effect on influenza virus infection and rotavirus and enterovirus infections.

Diuretic detoxification

The diuretic function of caffeine in black tea is achieved by the kidneys promoting the filtration rate of water in the urine. At the same time, the stimulatory effect of caffeine on the bladder can not only help diuresis, but also help sober up and relieve alcoholism. At the same time, tea polyphenols in black tea can not only precipitate nicotine in tobacco, but also be excreted with urine, but also can remove free radicals in smoke and reduce the toxic effects of smoke on human body. For heavy metal poisons, tea polyphenols have a strong adsorption effect, so drinking more tea can also alleviate the toxic effects of heavy metals.

Black tea health

Black tea is different from other teas in the choice of raw materials, processing technology (fermented flowers), etc., resulting in the composition and proportion of the biochemical components of black tea and the resulting pharmacological functions.

A large number of clinical trials have proved that teas formed through the participation of microorganisms in the dumping process have significant differences in the content of tea from red and green tea, and the functions they perform are also different. l It has significant effects in reducing blood fat, lowering blood pressure, lowering blood sugar, losing weight, preventing cardiovascular disease, and anti-cancer. Studies have shown that the special health benefits of black tea are related to its richness in tea polysaccharides.
