Antimutagenic and anticancer effects of 1
Tea polyphenols in tea have strong antioxidant and free radical scavenging effects. A large number of studies have confirmed that tea polyphenols can not only inhibit various physical (radiation, high temperature, etc.)-induced mutations (antimutagenic effects). ) and chemical (carcinogenic) factors, but also inhibit the proliferation of cancer tissue (anticancer effect).
The results showed that white tea had strong antimutagenic activity against Salmonella, which was stronger than green tea. The ethanol extracts of green tea and white tea have certain inhibitory effects on TA 100 induced by mutagen N- methyl-N ′-nitro -N- nitrosoguanidine (MNNG, 0.4μg/ dish).
According to the research data of the American Cancer Research Foundation, white tea is a new anticancer substance, which can constantly play tricks, inhibit and shrink the tumor of liver cancer and improve human immune function. Zinc in tea also has anti-cancer and anti-aging effects.
2 bactericidal and antiviral effects
White tea contains tea polyphenols, tea pigments, tea polyphenols, aromatic substances and other functional substances, all of which have strong bactericidal, anti-inflammatory and antiviral effects. Tea polyphenols have a strong inhibitory and killing effect on a variety of bacteria and fungi.
Studies have shown that white tea extract has anti-human pathogenic virus effect. White tea extract and its tea polyphenols can inhibit the main pathogenic microorganisms in the oral cavity, so it is better to add white tea extract to toothpaste to protect teeth.
3 anti-radiation effect
White tea contains anti-radiation substances such as tea polyphenols, tea polysaccharides, amino acids, vitamin C and B vitamins. It can directly participate in scavenging free radicals of radiation products, improving the activity of antioxidant enzymes in vivo, regulating and enhancing cellular immune function to improve the resistance of cells to radiation, promoting the proliferation and growth of hematopoietic and immune cells, and repairing radiation-damaged tissues.
Tea has a protective effect on all kinds of radiation damage, which can improve vitality, protect skin, improve immune function and protect hematopoietic tissue. Tea is a "drink of the atomic age", which can protect you from radiation.
4 the role of prevention and treatment of cardiovascular and cerebrovascular diseases
Studies have proved that tea and its functional components have the functions of inhibiting lipid peroxidation, anticoagulation, promoting fibrinolysis, anti-platelet aggregation, lowering blood pressure, reducing blood lipid, preventing atherosclerosis and protecting myocardium. Therefore, it will be helpful to the prevention and treatment of cardiovascular and cerebrovascular diseases by regulating various indexes in blood and improving cardiovascular and cerebrovascular systems.
Caffeine in white tea can promote coronary artery dilation, increase myocardial contractility, increase cardiac output, improve blood circulation and accelerate heartbeat. Tea polyphenols can resist oxidation, scavenge free radicals and prevent the body from being oxidized; Can inhibit arteriosclerosis and platelet aggregation, and prevent thrombosis; Can lower blood sugar and blood pressure.
Flavonoids in white tea can keep phlogiston well during processing, which is an important part of vitamin P and also has an obvious effect on reducing vascular permeability. Tea pigment has a good hypolipidemic effect. Tea polysaccharide also has a significant effect on hyperlipidemia.
5 hypoglycemic effect
White tea retains the active enzymes needed by human body during processing. Drinking white tea for a long time can significantly improve lipoprotein lipase, promote lipocatabolism, effectively control insulin secretion, delay glucose absorption, decompose excess sugar in the body and promote blood sugar balance. Drinking white tea can promote the secretion of pancreatic juice, change the sugar metabolism in the human body, reduce the source of blood sugar, increase the number of ways, and thus reduce blood sugar.
6 anti-oxidation, anti-aging, enhance immunity
The important reasons for human aging are: one is caused by excessive free radicals, and the other is lipid peroxidation in the body.
Tea polyphenols in white tea have strong antioxidant and free radical scavenging effects. Drinking tea can increase the number and activity of white blood cells and lymphocytes in human body, thus enhancing human immunity. Tea polyphenols and tea polysaccharides in tea can enhance the function of macrophages. Tea polyphenols have obvious inhibitory effect on hemolysin. Tea polysaccharide can increase the number of lectin antibodies in serum, thus enhancing the immune function of antibodies.
7 antiallergic effect
Tea polyphenols (especially ester catechins), caffeine and tea polyphenols in white tea have antiallergic effects.
Protective effect of 8 on renal function
Modern medical research shows that tea and its effective components have inhibitory effects on many factors leading to nephropathy. In addition, they also have the functions of benefiting qi and removing blood stasis, detoxicating and resolving turbidity, anticoagulation and improving hemorheology. Therefore, tea may inhibit the induction and progress of nephropathy, improve the symptoms of nephropathy, and thus prevent and treat nephropathy.
Caffeine in white tea also has diuretic effect. Tea polyphenols inhibit the production of methylguanidine and prevent uremia. Tea polyphenols can prevent immune hyperfunction and inflammatory reaction, inhibit cell and body lipid peroxidation, thus inhibiting the occurrence of nephropathy; At the same time, tea polyphenols can also resist coagulation, thrombosis and improve hemorheology, thus preventing the progress of nephropathy.
9 the role of protecting the liver
White tea extract has protective effect on liver injury, and the protective effect increases with the increase of concentration. Tea polyphenols, flavonoids, theanine and other active substances in white tea can improve the antioxidant capacity of hepatocytes, protect the integrity and function of hepatocyte membrane structure, and achieve the effect of antagonizing the damage of carbon tetrachloride to hepatocyte membrane.
Caffeine in white tea has a protective effect on the liver, enhances diuretic effect, and is also conducive to the discharge of stones. Theanine can reduce the concentration of abdominal fat, fat and cholesterol in blood and liver, and has the functions of protecting liver and antioxidation.
10 beauty function
A large number of scientific studies have proved that tea polyphenols, the main medicinal component of tea, can achieve health care and beauty effects through antioxidant, anti-aging, antibacterial, anti-radiation and immunomodulation. Tea polysaccharides, vitamins, aromatic substances and other components in tea also have health care and beauty effects.
Drink tea regularly, especially white tea, to keep your body warm, avoid sores and acne, delay skin aging and wrinkle formation, and inhibit skin spots and pigmentation; Keep skin moist, fair and ruddy; As the window of the soul, eyes should be crystal clear and bright.
Drinking more tea and supplementing vitamins C, E and A will help to improve and protect your eyesight. Strengthening teeth and preventing caries, using tea mouthwash from childhood and using toothpaste added with tea can all achieve the effect of strengthening teeth and preventing caries. Ancient medical books all mentioned that "drinking tea for a long time makes people lose weight and reduce fat", and tea has the effect of "losing weight" and "reducing fat".
