Long-term drinking of black tea is an important source of essential minerals and vitamins for residents in northwest China who live on beef, mutton and cheese and lack vegetables and fruits. Therefore, Anhua black tea is known as "tea of life" in the local area.
2, help digestion, greasy, smooth stomach.
Caffeine, vitamins, amino acids, phospholipids and so on. Black tea helps the human body to digest and regulate fat metabolism, while the stimulation of caffeine can improve the secretion of gastric juice, thus increasing appetite and helping digestion.
Japanese scholars have proved through scientific experiments that black tea has a strong function of relieving greasy and helping digestion, which is why residents in northwest China especially like this kind of tea. In addition, black tea can also improve the intestinal microbial environment and has the function of moistening the stomach. China has a tradition of treating abdominal distension and dysentery with aged black tea.
3. Reduce blood fat, lose weight, soften human blood vessels and prevent cardiovascular diseases.
Black tea has good effects of degrading fat, anticoagulation, promoting fibrinogen dissolution, relaxing blood vessel wall and increasing effective diameter of blood vessels, thus inhibiting the formation of atherosclerotic plaques on the inner wall of aorta and coronary artery, thus achieving the purposes of lowering blood pressure, softening blood vessels and preventing and treating cardiovascular diseases.
1990, the general hospital of the Chinese people's liberation army observed the situation of 55 veteran cadres with hyperlipidemia after taking black tea 180 days (3 grams a day). Among them, the blood lipid content in 50 cases decreased significantly.
Epidemiological investigation in Xinjiang, Inner Mongolia, Qinghai and other areas where Fuzhuan tea is mainly consumed shows that drinking black tea for a long time has a good regulatory effect on human blood lipid, blood sugar, blood pressure and arteriosclerosis, and has a good regulatory effect on body weight and body shape.
Anhua black tea is called "slimming tea" by Japanese, "beauty tea" by Koreans and "slim and healthy tea" by Southeast Asians. Anhua black tea has become the first choice to reduce the "three highs".
4. Anti-oxidation, anti-aging and longevity.
According to the free radical theory of aging, under normal physiological conditions, free radicals in the human body are constantly produced and eliminated, which is in a state of balance. Black tea is not only rich in antioxidants, such as catechins, tea pigments, flavonoids, vitamin C, vitamin E, vitamin D and carotene. It also contains a large number of trace elements with antioxidant effects, such as zinc, manganese, copper and selenium.
Catechins, theaflavins, theanine and tea polysaccharides in black tea, especially high-content compound flavonoids, all have the function of scavenging free radicals, so black tea has the function of antioxidation and delaying cell aging.
5. Anti-cancer and anti-mutation
In the late 1970s, scientists all over the world found that tea or tea extract had inhibitory effects on the occurrence of various cancers. Qualcomm screening technology, an advanced technology of modern drug screening, was used in Hunan Agricultural University to study the Qualcomm screening of black tea tumor cell model SGC790 1, which proved that black tea had obvious inhibitory effect on tumor cells.
bring down the blood pressure
The effect of black tea on lowering blood pressure has long been reported in the medical field. In addition, caffeine and catechin in tea can soften blood vessels and lower blood pressure by dilating blood vessels.
Professor Lou Fuqing and other authoritative experts have found that tea pigment has obvious effects of anticoagulation, promoting fibrinolysis, preventing platelet adhesion and aggregation, and inhibiting the proliferation of arterial smooth muscle cells. It can also significantly reduce triglyceride and low-density lipoprotein in animal serum, increase high-density lipoprotein in serum, significantly inhibit ACE enzyme, and has antihypertensive effect.
7. Improve carbohydrate metabolism, lower blood sugar and prevent diabetes.
The results showed that the content of tea polysaccharide in black tea was the highest, and its component activity was stronger than other teas.
This is because in fermented tea, sugar chains and peptide chains with short phase length are formed due to the action of glycosidase, protease and hydrolase. Short peptide chains and long peptide chains are more easily absorbed and have stronger biological activity. Therefore, this long-dead fermented tea, especially Anhua black tea polysaccharide, has better hypoglycemic effect than other teas.
8. Sterilization and anti-inflammatory
Studies have shown that theaflavins are not only an effective free radical scavenger and antioxidant, but also have obvious antibacterial effects on Botox, Enterobacteriaceae, Staphylococcus aureus, Bacillus spongiform and Bacillus cereus. In addition, theaflavins can also inhibit the invasion of influenza virus and the infection of rotavirus and enterovirus.
9. diuretic detoxification, reduce the poison of alcohol and tobacco
Tea diuresis, and can decompose some toxins in tobacco, especially can inhibit the impact of nicotine on human health.
Extended data:
Taboo of drinking tea
It is not advisable to drink a lot of tea before meals.
Drinking a small amount of tea before or during meals is not a big problem, but if you drink a lot of tea or drink too much tea, it will affect the absorption of many macro elements (such as calcium) and trace elements (such as iron and zinc). And drinking tea before meals will also stimulate the stomach. If it's bad for your stomach, please stop drinking tea half an hour before meals.
It is not advisable to drink tea immediately after a meal.
Drinking tea immediately after meals will reduce the absorption of iron, and if the food is rich in phosphorus and calcium, it will combine with oxalate ions in tea, which is not easy to be excreted, and it is easy to get lithiasis. It is best to drink tea after meals 1 hour, which can help digestion.
It is not advisable to drink tea on an empty stomach, and be careful not to get drunk.
Drinking tea on an empty stomach will dilute gastric juice and reduce its secretion. Tea soup is weakly acidic, with a PH of 5-6. The acidity of gastric juice is stronger than that of tea soup, and some alkaline substances are reduced by neutralization.
For green tea, yellow tea and white tea with herbal tea, drinking tea on an empty stomach will cool the spleen and stomach, leading to gastrointestinal problems, and may also cause palpitations, upset, dizziness and trembling, commonly known as tea drunkenness; For black tea and black tea with weak tea, drinking tea on an empty stomach is prone to hunger, causing dizziness, hypoglycemia and other drunken tea phenomena.
4. It is not advisable to take medicine with tea, so as not to affect the curative effect.
Different kinds of tea have chemical components ranging from dozens to hundreds. After being brewed into tea soup, it also plays a combination role. If tea is used as medicine, various drugs for various diseases are mixed with tea soup, which will cause some changes and reduce the efficacy of the original medicine.
5. Don't drink overnight tea
Protein and sugar in overnight tea will become nutrients for bacteria and mold if it is kept for a long time. Tea soup is easy to deteriorate, with poor aroma and taste. Drinking overnight tea has lost the meaning of healthy drinking.
6. Don't drink too strong tea
Old tea drinkers who have been drinking tea for many years will prefer strong tea. In fact, strong tea, especially green tea, yellow tea and green tea, contains a lot of caffeine, which is irritating, easy to harm the stomach and kidneys, and can cause problems such as excitement, insomnia and headache, especially for people with high blood pressure, stomach problems, anemia and heart disease.
7. Don't drink new tea.
The so-called new tea refers to the tea that has been picked for less than a month. From the point of view of nutrition, the nutrients of the freshest tea are not necessarily the best, because these tea leaves have not been placed for a period of time, and some substances that have adverse effects on the body, such as polyphenols, alcohols and aldehydes, have not been completely oxidized, so the newly brewed tea should be placed for more than one month before drinking.
