Nine functions of black tea, I believe many people have drunk black tea, and black tea is a very common kind of tea in life. Black tea is rich in nutrition and can supplement the nutrition needed by human body. Black tea also has many functions. Here are nine effects of black tea!
Nine Functions of Black Tea 1 Anhua Black Tea is named after it is produced in Anhua County, Hunan Province, China. It is one of the famous teas in ancient China. It was extinct in May of last century, so it is unknown.
20 10 Hunan black tea entered China Shanghai World Expo and became one of the top ten famous teas in China World Expo. Anhua black tea once again entered the sight of tea people and became their new favorite. Its characteristic thousand two hundred teas are a must, and the other is the nine functions of Anhua black tea.
Nine functions of black tea
1, supplement dietary nutrients
Anhua black tea contains rich and heavy nutrients, the most important of which are vitamins and minerals, in addition to protein, amino acids and sugars.
For the residents in northwest China who live on beef, mutton and cheese and lack vegetables and fruits, drinking Hunan Anhua black tea for a long time is the primary source of essential minerals and vitamins, so it is called the tea of life.
2, help digestion, greasy, smooth stomach.
Caffeine, vitamins, amino acids and phospholipids in Anhua black tea contribute to human digestion and regulate fat metabolism. The stimulation of caffeine can improve the secretion of gastric juice, thus increasing appetite and helping digestion.
Japanese scholars have proved through scientific conservation that Anhua black tea has a strong function of relieving boredom and promoting digestion, which is why meat eaters especially like this kind of tea.
3. Reduce blood fat, lose weight, soften human blood vessels and prevent cardiovascular diseases.
High blood lipid content will make lipid deposit on blood vessel wall, which will cause atherosclerosis and thrombosis.
Anhua black tea has good functions of lowering blood fat, anticoagulation, promoting fibrinogen dissolution and obviously inhibiting platelet extraction. It can also relax the wall of blood vessels and increase the useful diameter of blood vessels, thus inhibiting the formation of atherosclerotic plaques on the inner wall of aorta and coronary artery. Achieve the purpose of lowering blood pressure, softening blood vessels and preventing and treating cardiovascular diseases.
Epidemiological observation and interpretation in Xinjiang, Inner Mongolia, Qinghai and other key consumption areas show that drinking Anhua black tea for a long time has an excellent regulatory effect on human blood lipid, blood sugar, blood pressure and arteriosclerosis, and has an excellent regulatory effect on body weight and body shape.
4, anti-oxidation, anti-aging, eliminating diseases and prolonging life.
According to the theory of free radicals related to aging, under the premise of normal physiology, free radicals in the human body are constantly multiplying and eliminating, and are in a state of balance.
Anhua black tea is not only rich in antioxidant substances such as catechins, tea pigments, flavonoids, vitamin C, vitamin E and D- carotene, but also contains a large number of trace elements with antioxidant effects such as zinc, manganese, copper (component of SOD) and selenium (component of GSHPX).
Catechins, theaflavins, theanine and tea polysaccharides in Anhua black tea, especially the huge flavonoids with more content, have the function of scavenging free radicals, so they have the functions of antioxidation and delaying cell aging.
5, anti-cancer, anti-mutation
Cancer is one of the diseases with extremely high mortality in the world. Since the late 1970s, scientists from all over the world have successively invented tea or tea extract, which has an inhibitory effect on a variety of cancers.
Qualcomm screening technology, the frontier technology of contemporary drug screening, was accepted by Hunan Agricultural University, which was able to conduct Qualcomm screening research on Anhua black tea tumor cell model SGC790 1, proving that Anhua black tea has obvious inhibitory effect on tumor cells.
6, lower blood pressure
It has long been reported that tea has the effect of lowering blood pressure. Recently, Japan reported that theanine, an amino acid in tea, can inhibit the increase of blood pressure by activating dopaminergic neurons.
Here, it is also found that caffeine and catechin in tea can relax the wall of blood vessels, increase the useful diameter of blood vessels, and lower blood pressure through vasodilation.
The tea pigment invented by Lou Fuqing and others in China has obvious effects of anticoagulation, promoting fibrinolysis, preventing platelet adhesion and extraction, and inhibiting the proliferation of arterial smooth muscle cells.
It can also significantly reduce triglyceride and low-density lipoprotein in serum of high-fat animals, improve high-density lipoprotein in serum, obviously inhibit ACE enzyme and have antihypertensive effect.
7. Improve carbohydrate metabolism, lower blood sugar and prevent diabetes.
Tea polysaccharide complex in Anhua black tea has an important role in lowering blood sugar. Tea polysaccharide complex, usually called tea polysaccharide, is a mixture with huge components and great changes.
The determination results of tea polysaccharide content in several kinds of tea show that Anhua black tea has the highest content of tea polysaccharide, and its component activity is stronger than other teas, which is due to the action of glycosidase, protease and hydrolase in fermented tea.
Compared with short sugar chain and peptide chain, short peptide chain is easier to be absorbed and has stronger biological activity, which is probably one of the reasons why fermented tea, especially Anhua black tea polysaccharide, has better hypoglycemic effect than other teas.
8, sterilization, anti-inflammatory
The important components of Anhua black tea soup color are theaflavins and thearubigins. According to research and publication, theaflavins are not only a useful free radical scavenger and antioxidant, but also have significant antibacterial effects on Botox, Enterobacteriaceae, Staphylococcus aureus, Clostridium perfringens and Bacillus cereus.
In addition, theaflavins can inhibit the invasion of influenza virus and the pollution of rotavirus and enterovirus.
9, diuretic detoxification, low alcohol and tobacco persecution
The diuretic effect of caffeine in Anhua black tea is realized by the kidney enhancing the filtration rate of water in urine. At the same time, the stimulating effect of caffeine on bladder not only helps diuresis, but also helps sober up and eliminate alcoholism.
At the same time, tea polyphenols in Anhua black tea can not only precipitate nicotine in tobacco, but also eliminate free radicals in smoke and reduce the persecution of smoke to human body.
Tea polyphenols have a strong adsorption effect on heavy metal poisons, so drinking more tea can also reduce the persecution of heavy metals.
skill
Vegetarians are easy to lack nutrients such as vitamin B, iron and calcium, and tea will hinder the body's absorption of these vitamins, so vegetarians need to drink tea in moderation.
In addition, people who are too thin, malnourished and lack of protein can remove fat from tea, which hinders the body's absorption of protein. Therefore, people who are too thin, malnourished and lack of protein can control drinking tea best.
Nine functions of black tea 2 functions 1
Black tea has the functions of quenching thirst, resisting radiation, preventing cancer, sobering up, promoting digestion, losing weight, delaying aging and lowering cholesterol. It can enhance the sensitivity of brain central nervous activity, improve thinking ability, lower blood pressure and inhibit arteriosclerosis.
Tea belongs to post-fermented tea, and its unique processing technology, especially the participation of microorganisms, makes it have special Chinese medicine effects. Rich in tea polysaccharide compounds, it is considered by the medical community to have the functions of regulating sugar metabolism (preventing diabetes), lowering blood lipid, lowering blood pressure, preventing coagulation and thrombosis, and improving immunity.
Clinical trials have proved that black tea has remarkable special effects and is irreplaceable by other teas. Qualcomm screening technology was used to select 10 modern disease model to study the effect of black tea on human health.
These include models of lowering blood pressure, blood lipid and blood sugar, models of inhibiting cancer cell proliferation, models of improving human immunity and so on.
Through model evaluation, it is found that Liangqian tea and Fuzhuan tea have obvious effects of lowering blood pressure, blood lipid and blood sugar, which are very helpful for human fat metabolism and weight control.
In addition, Qianliang tea extract can also inhibit the proliferation of gastric cancer cells and liver cancer cells. Hundreds of years of history have proved that it is the life drink of frontier herders. "It is better not to drink tea for one day than not to eat for three days", which is the testimony of the unique pharmacological effects of black tea.
Nowadays, with the change of people's lifestyle and diet structure, it is more and more necessary to drink black tea.
Due to the unique flowering process of Fuzhuan tea, a cephalosporium is produced, and a Punol component is produced in the fermentation process, which oxidizes excess cholesterol in the human body and prevents fat accumulation. Dr. Wang Zhiwei, a world-class microbiologist, studied Japanese microorganisms and food fermentation 18 years, saying that Fuzhuan tea is the most magical food in the world.
Efficacy 2
During the storage of aged dark tea, microorganisms have undergone generations of reproduction and metabolism, resulting in a series of unknown small molecular active substances, namely secondary metabolites, which form slowly.
Moreover, the chemical properties are unstable, and only by maintaining the original natural state will it have a special effect on the human body. The efficacy is similar to that of the Millennium Ganoderma lucidum.
Most people in Anhua have this experience. The effect of drinking aged black tea to treat gastrointestinal diseases can be said to be a "medicine for treating diseases".
The main components of dark tea soup color are theaflavins and thearubigins. The results show that theaflavin is not only an effective free radical scavenger and antioxidant, but also has many physiological functions such as anticancer, antimutagenic, antibacterial and antiviral, improving and treating cardiovascular and cerebrovascular diseases, treating diabetes and so on.
The main functional component of black tea is tea complex polysaccharide compound, which is considered by the medical community to have the functions of regulating sugar metabolism (preventing and treating diabetes), lowering blood lipid, lowering blood pressure, anticoagulating blood, resisting thrombus and improving immune ability. Clinical trials have proved that these special functions of black tea are remarkable and irreplaceable by other teas.
Black tea can inhibit fat accumulation in the lower abdomen. When it comes to obesity, people immediately think of abdominal fat, and black tea has always played an obvious role in the increase of fat.
Black tea is also a healthy drink with low caffeine (high maturity of raw materials, baking and other factors). Compared with cola and other teas, black tea does not affect sleep. It can be drunk all night, and it is very effective to insist on drinking every day.
Function of black tea
Its main varieties are Hunan Black Tea, Hubei Laobian Tea, Sichuan Biancha, Guangxi Liubao Sancha Tea and Yunnan Pu 'er Tea. Among them, Yunnan Pu 'er tea enjoys a long-standing reputation at home and abroad. It is an effective tea, which belongs to the alkaline category and can be preserved for decades. The longer it is kept, the more valuable it is!
Of course, it tastes good, because it belongs to black tea and has no bitterness of green tea. It is the same as clearing intestines, eliminating fat, scraping oil and wiping water, and it will not have a great effect on weight loss;
It also has the functions of caring skin, treating dermatoses (preventing melanin from depositing on the skin), refreshing mind, promoting digestion, treating dysentery, sobering up, improving immunity and reducing blood fat.
Black tea, represented by Pu 'er and Lao Lu 'an, is warm and moist, and has the advantages of clearing kidney, reducing fire, eliminating fat and resolving stagnation. For example, when eating more moon cakes, it is perfect to eliminate stagnation and fat, Xian Yi, young and old. Suitable water temperature: 100℃ for brewing.
Black tea contains many effective components that are beneficial to human health. There is a saying in the northwest that there is no food for three days and no tea for one day. This kind of tea is black tea.
We also made a field survey, and herdsmen reported that if they don't drink black tea for one day, their stomachs will swell, and if they don't drink black tea for three days, they will feel weak as if they were ill.
Herdsmen give horses boiled tea dregs, which makes them more energetic. We have also noticed a phenomenon that some nomadic people live on grass.
There are no vegetables and fruits in the whole winter, and the plant vitamins needed by the human body are completely taken from tea. After a winter, everyone is healthy, which also proves the healthy effect of black tea on human body from another side.
Nine effects of black tea 3 1, reducing fat and losing weight
Obesity is a series of diseases caused by specific biochemical factors, such as diet regulation and energy metabolism disorder. A series of diseases caused by obesity have become the main killers endangering human health.
Tea polyphenols and their oxidation products in black tea can dissolve fat and promote the discharge of lipid substances, thus reducing the contents of total cholesterol, free cholesterol, low-density lipoprotein cholesterol and triglyceride in blood, thus reducing cholesterol deposition on arterial wall and reducing the incidence of arterialization.
It can also activate protein kinase, accelerate fat decomposition and reduce body fat content. Through experiments on human body, scientists found that compared with people who drink ordinary water, the average daily energy consumption of people who drink tea is 67eal higher, and the fat oxidation rate is higher than 12%. This proves that black tea does have the function of reducing fat and weight.
2. Enhance gastrointestinal function and improve immunity.
The effective components of black tea can not only inhibit the growth of harmful microorganisms in human stomach, but also promote the growth and reproduction of beneficial bacteria (such as lactic acid bacteria), which has a good effect on regulating gastrointestinal function. Its alkaloids can promote the secretion of gastric juice, and flavanol can significantly enhance gastrointestinal peristalsis.
It is also found that catechins and tea saponin in black tea can kill and inhibit the growth of oral bacteria, helicobacter, Escherichia coli, typhoid and paratyphoid bacilli, staphylococcus and other pathogenic bacteria.
Therefore, it has obvious functions of relieving stagflation, stopping diarrhea and eliminating constipation. It plays an important role in white-collar workers who often sit and work, and is also a folk medicine for stopping diarrhea.
Theanine in black tea has a good effect on enhancing human immunity.
3, anti-aging, regulating the role of the brain.
The natural aging of human body and degenerative diseases including tumor and cardiovascular diseases have a common process, that is, cells are damaged by oxygen free radicals. More than 95% of free radicals in human body are oxygen free radicals, which are the basis of destroying biological macromolecules and participate in the occurrence and development of various diseases and aging.
Under normal circumstances, free radicals in the human body are constantly produced and removed, which is in a state of balance. However, in some cases, the production and elimination of free radicals are out of balance, which leads to protein's degeneration and decreased enzyme activity, thus causing various diseases and accelerating aging.
Catechins and compound flavonoids in black tea have very active hydroxyl hydrogen, which can provide a large number of hydrogen protons to react with free radicals and remove excess free radicals, thus protecting human health and longevity.
4. Reduce blood pressure and blood sugar
Theanine in black tea can inhibit the increase of blood pressure, while alkaloids and flavonoids can relax the wall of blood vessels, increase the effective diameter of blood vessels, and reduce blood pressure by relaxing blood vessels.
Diabetes is one of the health killers of modern middle-aged and elderly people, and with the improvement of people's living standards and the intensification of population aging, the incidence of diabetes is gradually increasing.
Diabetes is still an incurable disease, which is mainly controlled by drugs and diet regulation. Studies have proved that tea polysaccharide in tea has obvious hypoglycemic effect, which is similar to insulin.
After injecting tea polysaccharide into mice for 7 hours, their blood sugar decreased by 70%. Black tea contains more tea polysaccharides and is an ideal drink to prevent and treat diabetes. Folk also use black tea to treat mild diabetes, and the stronger the tea, the better the effect.
Black tea also has common health care functions such as cancer prevention, blood lipid reduction, radiation protection and anti-inflammation.
