First, reduce blood fat and lose weight
Black tea has good effects of dissolving human fat, anticoagulating blood, promoting fibrinolysis and obviously inhibiting platelet aggregation. It can also relax the blood vessel wall, increase the reasonable blood vessel diameter, and then inhibit the occurrence of atherosclerotic soft spots in pulmonary artery and coronary artery lumen. Achieve the purpose of lowering blood pressure, cleaning up vascular garbage and preventing cardiovascular diseases.
Tea polysaccharides in black tea are rich and colorful, and have the specificity of softening peroxides in blood vessels and blood. After eating black tea, the specificity of blood sugar composition and peroxide in blood decreased obviously. Drinking black tea for a long time has an excellent buffering effect on blood sugar, blood sugar value, blood pressure and arteriosclerosis, and has an excellent control effect on resting weight and body shape.
Second, diet nutrition.
Black tea contains rich and colorful nutrients, especially vitamins and minerals, as well as protein, carbohydrates and glycogen. For the residents in the western region, whose diet is dominated by beef and cheese, who lack vegetables, fruits and fresh fruits, drinking Hunan black tea for a long time is the key source of essential minerals and vitamins for human body, and is called "tea of life".
Third, reduce blood fat.
Tea polysaccharide nitric oxide synthase in black tea is the main component of reducing blood lipid. Tea polysaccharide from black tea has the largest component, and its component specificity is better than other tea series. This is because sugar chains and peptide chains with relatively short lengths are produced in fermented tea due to the efficacy of enzymes such as glycolytic enzymes, trypsin and hydrolase. The short peptide chain is easier to be digested and absorbed, and its biological activity is stronger, which may be one of the reasons why fermented tea, especially black tea polysaccharide, has better blood lipid-lowering effect than other tea systems.
Fourth, promote digestion and oil decomposition.
Caffeine, vitamins, carbohydrates, unsaturated fatty acids, etc. Black tea is beneficial to the digestion and absorption of human body and regulates the decomposition of fat, while the stimulation of caffeine can improve the excretion of gastric acid, thus improving appetite and promoting digestion. According to scientific research, Japanese experts and scholars have confirmed that black tea has a strong function of relieving boredom and helping digestion, which is why China people like this kind of tea very much.
In addition, black tea can also improve the natural environment of intestinal microorganisms and dredge the stomach. In China, old black tea is used to treat abdominal distension, dysentery and indigestion.
Verb (abbreviation for verb) is antioxidant.
Black tea not only contains rich and colorful antioxidant substances such as catechins, tea pigments, flavonoids, polysaccharides, vitamin C, vitamin E, D- carotene and so on. It also contains many antioxidant nutrients such as zinc, manganese, copper (the constituent element of SOD) and selenium (the constituent element of GSHPX). Catecholic acids, theaflavins, tea polyphenols and tea polysaccharides in black tea, especially various flavonoids with more components, all have the function of lowering cholesterol, so they have the effects of antioxidation and delaying cell aging.
Sixth, cancer prevention.
Qualcomm screening technology, the frontier technology of contemporary drug screening, was selected by Hunan Agricultural University to carry out Qualcomm screening scientific research on black tea tumor cell model SGC790 1, which confirmed that black tea had a significant inhibitory effect on tumor somatic cells.
Seven, lower blood pressure
It has long been reported that tea has the effect of lowering blood pressure. Tea polyphenols are unique carbohydrates in tea, which can inhibit the rise of blood pressure according to active dopaminergic nerve cells. Here, it is also found that caffeine and catechin in tea can relax the wall of blood vessels, increase the reasonable diameter of blood vessels, and lower blood pressure according to the left ventricle of blood vessels. Black tea has obvious effects of anticoagulation, promoting fibrinolysis, avoiding platelet adhesion and aggregation, and inhibiting the proliferation of aortic smooth muscle cells. It can also significantly reduce triglycerides and low-density proteins in blood cells of high-fat small animals, increase high-density proteins in blood cells, have obvious inhibitory effect on ACE enzyme, and have the practical effect of lowering blood pressure.
