The efficacy and function of brick tea
Supplementing dietary nutrition
Black tea is rich in nutrients, the most important of which are vitamins and minerals, as well as 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 black tea for a long time is an important source of essential minerals and vitamins, so it is called the tea of life.
Help digestion and relieve greasy.
Caffeine, vitamins, amino acids, phospholipids and so on. Black tea helps the human body to digest and regulate fat metabolism. The effect of caffeine can improve the secretion of gastric juice, thus stimulating 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 meat eaters especially like this kind of tea.
The food structure of ethnic minorities in northwest China is beef, mutton and cheese, so there is a saying that "it is better not to drink tea for three days", which has a lot to do with the efficacy of tea in "removing fat and getting tired" and "removing fishy smell from meat".
In addition, black tea can also improve the intestinal microbial environment and has the function of moistening the stomach. In China, there is a tradition of using old black tea to treat abdominal distension, dysentery and indigestion.
Reducing fat and weight to prevent diseases.
High blood lipid content will make lipid deposit on blood vessel wall, which will cause atherosclerosis and thrombosis. Black tea has good effects of degrading fat, anticoagulation, promoting fibrinogen dissolution and significantly inhibiting platelet aggregation. It can also relax the wall of blood vessels and increase the effective 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.
Tea polysaccharide rich in black tea can reduce blood lipid and peroxide activity in blood. 1May, 1990 to1May, 19991May, China People's General Hospital observed the situation of 55 hyperlipidemia patients among 155 veteran cadres. After taking black tea 180 days, it was observed that * * * was 3 grams per day.
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.
Antioxidant and anti-aging
According to the free radical theory of aging, under normal physiological conditions, free radicals in the human body are constantly produced and removed, which is in a state of balance. Black tea is not only rich in catechins, tea pigments, flavonoids, vitamin C, vitamin E, D- carotene and other antioxidant substances, but also contains a large number of trace elements with antioxidant effects, such as zinc, manganese, copper, SOD, selenium and GSH PX. Catechins, theaflavins, theanine and tea polysaccharides in black tea, especially compound flavonoids with high content, all have the function of scavenging free radicals, so they have the functions of antioxidation and delaying cell aging.
Anti-cancer and anti-mutation
Cancer is one of the diseases with extremely high mortality in the world.
Since the late 1970s, scientists all over the world have found that tea or tea extract can inhibit the occurrence of various cancers. Qualcomm quality screening technology, the frontier technology of modern drug screening, was used by Hunan Agricultural University to screen the tumor cell model SGC790 1 of black tea, which proved that black tea had obvious inhibitory effect on tumor cells.
bring down the blood pressure
It has long been reported that tea has the effect of lowering blood pressure. Japan reported that theanine, a unique amino acid in tea, can inhibit the increase of blood pressure by activating dopaminergic neurons. It is also found here that caffeine and catechin in tea can relax the wall of blood vessels, increase the effective diameter of blood vessels and reduce blood pressure by relaxing blood vessels. Lou Fuqing and others in China 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 serum of high-fat animals, increase high-density lipoprotein in serum, significantly inhibit ACE enzyme, and has antihypertensive effect.
In fact, in addition to the above functions and functions, brick tea has many functions and functions. For example, it can lower blood sugar, sterilize and diminish inflammation, diuretic and detoxify, and preserve health. So you can drink more brick tea at ordinary times.
