Chinese Name: Tea polyphenols Nickname: Called tea tanning or tea tannins Interpretation: The general term for polyphenols in tea Contains: flavanols, anthocyanins, flavonoids, flavonols and phenolic acids Important content: flavanols (catechins), accounting for about 70% of the total amount of tea polyphenols Features: It is one of the main ingredients that form the color and fragrance of tea, and it is also one of the main ingredients in tea with health care functions
Not all teas have the same polyphenol content. The deeper the degree of fermentation of tea leaves, the greater the number of tea polyphenols converted into other substances, and the content of tea polyphenols will be reduced accordingly.
Green tea is not fermented, the content of tea polyphenols is quite rich, there are data show that the content of tea polyphenols in green tea is 144% higher than that of black tea of the same quality, and about 59% higher than that of oolong tea of the same quality.
In addition to the variety, the quality of the tea also affects the content of tea polyphenols.
For example, when making tea leaves, the more tender the tea leaves, the better the quality. Because the young leaves grow at the top, closest to the sun, they can fully photosynthesis and will synthesize more phenolic substances.
What is the use of tea polyphenols
➀ Anti-aging
Tea polyphenols have strong antioxidant and physiological activity, are the body's free radical scavengers, can inhibit the lipoxygenase and lipid peroxidation in the mitochondrials of the skin, thus having an anti-aging effect.
Studies have shown that 1 mg of tea polyphenols is equivalent to 9 micrograms of superoxide dismutase (sod) in scavenging excess free radicals harmful to the human body, which is much higher than other similar substances.
The antioxidant resistance of tea polyphenols is significantly 18 times stronger than that of vitamin e, and has a synergistic effect with vitamins C and e.
➁ Relieves allergies
Tea polyphenols can strongly inhibit the release of histamine, and experiments have proved that the anti-allergic reactions and anti-skin allergic reactions of tea polyphenols are 2 to 10 times stronger than the inhibitory effect of commonly used antiallergic drugs.
➂ Detoxification
Tea polyphenols have a strong adsorption effect on heavy metals, and can form complexes with heavy metals to produce precipitation, which is conducive to reducing the toxic effect of heavy metals on the human body.
In addition, tea polyphenols also have the effect of improving liver function and diuresis, so they have a good anti-antidote effect on alkaloid poisoning.
➃ Aids digestion
The caffeine in tea polyphenols can increase the secretion of gastric juice, can help digestion, and enhance the ability to break down fat. The so-called "long-term food makes people thin" is here.
➄ Radiation protection
Tea polyphenols and their oxidation products have excellent radiation resistance, can absorb radioactive substances, prevent their diffusion in the human body, known as natural ultraviolet filters.
➅ Dental guards
Tea polyphenolic compounds can kill lactic acid bacteria and other carious bacteria present in the tooth gap, have the effect of inhibiting glucose polymerase activity, and effectively interrupt the process of caries formation.
Protein foods that remain between the teeth become a matrix for the proliferation of spoilage bacteria, and tea polyphenols can kill such bacteria.
➆ Beauty
Tea polyphenols are water-soluble substances, with it to wash the face can remove the oiliness of the face, tighten the pores, with disinfection, sterilization, anti-skin aging, reduce the ultraviolet radiation in the sun on the skin damage and other effects.
➀ Cancer
Green tea and cancer prevention are not new topics for a long time.
Tea polyphenols can scavenge harmful free radicals, block the lipid peroxidation process, improve the activity of enzymes in the human body, thereby playing an anti-mutation and anti-cancer effect.
According to relevant data, the tea polyphenols (mainly catechin compounds) in tea are beneficial for the prevention and adjuvant treatment of various cancers such as stomach cancer and bowel cancer.
➁ Hypertension
Tea polyphenols have a strong effect of inhibiting the activity of conversion enzymes, so they can play a role in reducing or maintaining blood pressure stability.
➂ Arteriosclerosis
Tea polyphenols, especially the catechins ecg and egc in tea polyphenols and their oxidation products theaflavins.
Helps inhibit atherosclerotic plaque proliferation, reduces the formation of fibrinogen with enhanced blood coagulation viscosity, and clears blood clotting, thereby lowering blood lipids and preventing liver and coronary atherosclerosis.
➃ Hyperglycemia
Tea polyphenols have a regulatory effect on the body's glucose metabolism disorders, can reduce blood sugar levels, thereby effectively preventing and treating diabetes.
➄ Stroke
Tea polyphenols have the effect of curbing the production of lipid peroxide and can eliminate vasospasm.
Maintain the elasticity of the blood vessel wall, increase the effective diameter of the blood vessel, reduce blood pressure through vasodilation, and thus effectively prevent stroke.
➅ Blood clots
Tea polyphenols have a protective and repairing effect on the deformation ability of red blood cells, and are easy to form complexes with thrombin, preventing fibrinogen from becoming fibrin.
In addition, tea polyphenols can effectively inhibit the rise of cholesterol content in plasma and liver, promote the excretion of lipids and bile acids, and effectively prevent the formation of blood clots.
➆ Asthma
Tea polyphenols can inhibit the allergic reactions caused by active factors such as antibodies, epinephrine, enzymes, etc., and have a significant effect on allergic diseases such as asthma.
➇ Constipation
As the saying goes: "morning tea a cup, a day of mighty wind", tea polyphenols have stimulated gastrointestinal response, accelerate the peristalsis of the large intestine to achieve the effect of treating constipation.
(9) Diarrhea
Tea polyphenols improve the body's comprehensive immunity, inhibit and kill various harmful pathogens that cause diarrhea, and soothe the tension of the stomach and intestines to achieve anti-inflammatory and anti-diarrhea effects.
(10) Scurvy
Tea polyphenols can promote the body's absorption of vitamin C, thereby effectively preventing and treating scurvy.
Drinking tea makes people healthy, largely thanks to the action of tea polyphenols.
Healthy living starts with a cup of tea.
