Reduce fat and lose 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, 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. The study also found that catechins and tea saponin in black tea can kill and inhibit the growth of oral bacteria, helicobacter, Escherichia coli, typhoid, paratyphoid, staphylococcus and other pathogenic bacteria, so they have obvious functions of relieving stagflation, stopping diarrhea and eliminating constipation, which is of great significance to 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 brain function:

There is a synchronous process between the natural aging of human body and degenerative diseases including tumors and cardiovascular diseases, 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 the functions of preventing cancer, reducing blood fat, preventing radiation and diminishing inflammation.

5. Prevention of cardiovascular diseases in the elderly:

Experts observed the changes of blood lipids in 50 elderly people before and after drinking black tea. Because flavanols and their oxidized polymers centered on catechins and their oxidized products in black tea are complex physiologically active substances, which play an important role in human health, blood cholesterol and glycerides have decreased to varying degrees. Black tea can reduce the activity of lipid peroxide, alleviate atherosclerosis and reduce the incidence of coronary heart disease.

6. Clearing heat and reducing fire, quenching thirst and promoting fluid production:

"Compendium of Materia Medica" records: "Tea tastes bitter and cold ... the best way to reduce fire, fire is a hundred diseases, and it will be clear when it is reduced." Qing? Zhao Xuemin's Compendium of Materia Medica records on page 26 of Volume 6: "Coarse japonica leaves must be boiled in water or soup, and then tasted at the water temperature. Its color is dark, bitter and sweet, and the food is clear to the heart and stomach, warm and bitter, slightly sweet, and the lower diaphragm is depressed and cold. " Drinking black tea can also regulate body temperature. Especially in dog days, the sun is like fire, and a cup of initialized black tea makes you feel cool and happy, far better than a cold drink to quench your thirst. The water extracts in Anhua black tea, such as polyphenols, sugars, pectin, amino acids, etc., can react with saliva in the mouth to quench thirst and produce fluid. After testing, drinking a cup of hot Anhua black tea can reduce the body temperature by 1-2℃ in just a few minutes.

7. Prevention of dental caries and elimination of halitosis:

Black tea contains iodine and fluoride. Iodine can prevent and treat hyperthyroidism; Fluoride is a component of human bones and teeth. Drinking black tea is one of the ways to supplement fluoride, especially in areas with low fluoride content in drinking water, black tea has obvious caries prevention effect. The demonstration of "Study on Fluorine Content in Tea and Its Influence on Human Health" shows that the main cause of dental caries is the poor calcium content in teeth. Fluoride ions have great affinity with calcium in teeth. The combination of the two can not only supplement calcium, but also enhance the ability of caries prevention. Tea (black tea) itself is an alkaline substance. Appropriate amount of fluorine is beneficial to the utilization and deposition of calcium and phosphorus in bones, accelerating the growth of bones, maintaining the health of bones and enhancing the resistance to dental caries. Fluorine has a certain preventive effect on osteoporosis. However, high fluoride can cause tooth discoloration (possibly yellow, brown and black), skeletal fluorosis (tendon deformation and limb pain), and damage the normal structure of bones and teeth. Black tea can deodorize, for example, washing pig's stomach with black tea is very effective; Vitamin C, aromatic oil and tea polyphenols in Anhua black tea can also remove bad breath.

8. Radiation protection and anti-cancer:

In Japan, tea is called "the drink of atomic age" and "tea can protect you from radiation" because of the comprehensive effect of phenols, lipopolysaccharide and vitamin C in tea absorbing radioactive substances. According to the survey after World War II, after the atomic bombing in Hiroshima, Japan, people who have long-term tea drinking habits have less radiation damage and higher survival rate. China has made tea into anti-radiation medicine, which has obvious effect on treating radiation injury and increasing the number of white blood cells. Scientific researchers have confirmed that tea has obvious anti-cancer effect. Studies have shown that tea can significantly block the synthesis of nitrosamines with carcinogenic effect; Ensure that normal DNA is not damaged, inhibit the synthesis of cancer cell DNA, and promote the breakage of cancer cell DNA; It affects the activities of various oncogenes and directly kills cancer cells. Tea is known as a natural anticancer agent, and drinking black tea regularly is one of the daily measures to prevent and suppress cancer.

9. Supplement nutrition and enhance physical fitness:

Black tea contains many vitamins, mainly vitamins A, B 1, B2, C, P, PP, K, E and other trace vitamins. Drinking black tea can supplement the body's demand for multivitamins and prevent some diseases. Black tea is rich in amino acids and is an important chemical component of black tea. It also contains a variety of minerals, especially trace elements rare in other foods, such as potassium, calcium, zinc, selenium, magnesium, molybdenum, phosphorus, iodine, etc., which have certain nutritional value and medicinal efficacy. Drinking black tea can also eliminate fatigue, clear the heart and improve eyesight, relieve cough and asthma, promote human metabolism and enhance physical fitness.

10. Sterilization, anti-inflammatory, hangover relieving and detoxification:

Polyphenols in black tea have obvious inhibitory effects on Escherichia coli, Staphylococcus and viruses. People use boiled strong tea (that is, strong black tea soup) to treat bacillary dysentery, or apply black tea to the wound to diminish inflammation and detoxify and promote wound healing. At present, there are Chinese patent medicines made of tea for treating dysentery and colds. Just like when you are drunk, sour wine needs tea. This is a poem by Wang Yangming in the Ming Dynasty, which shows that people have long recognized that drinking tea can relieve alcohol, because tea polyphenols can neutralize alcohol. Drinking tea can precipitate harmful substances such as nicotine in tobacco leaves and excrete them through urine. Black tea is a sobering agent and an antidote for smokers.
